Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments It is only a part of the embodiments of the present disclosure, but not all the embodiments. The components of the disclosed embodiments generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations.

Public cloud refers to cloud services provided by third-party providers to users through the public Internet. Users can access the cloud through the Internet and enjoy various services, including but not limited to computing, storage, and networking. Generally, a private network (Virtual Private Cloud, VPC) software-defined network (Software Defined Network, SDN) architecture applied to a public cloud includes a client, an intermediate module, and a computing node server. connected.

In one solution, the intermediate module can use a remote dictionary service (Remote Dictionary Server, Redis) as a storage solution, and use Kafka, a distributed publish-subscribe message system, as a message queue. When the client receives the configuration data, it sends the configuration data to the intermediate module, and the intermediate module caches each received configuration data so that the computing node server can read it. Due to the aging of Kafka cache data, configuration data may be lost in intermediate modules, further reducing the credibility of the public cloud.

At the same time, using Kafka as a message queue, when computing nodes join or leave, there will be a balance rebalance phenomenon, affecting the working process of the agent broker, resulting in low efficiency of the entire Kafka throughput data, and with the increase of computing nodes, the efficiency will decrease reduce.

In another solution, the intermediate module can use the distributed storage system Etcd for data storage, so that the computing nodes can monitor watch Etcd and obtain configuration data from Etcd. On the one hand, due to the need for data synchronization between the various storage modules in Etcd, when the number of computing nodes is large, the amount of configuration data is also large, so that the data that needs to be synchronized between the various storage modules in the intermediate module is large, resulting in The efficiency of computing nodes to pull data is low. On the other hand, the number of watch connections that Etcd can receive is limited. When the number of computing nodes is large in a public cloud application scenario, Etcd cannot meet the needs of large-scale computing nodes.

At the same time, Etcd is a key-value (Key-Value, kv) storage structure, which can represent the current configuration status of computing nodes, but cannot represent the resource configuration process of computing nodes. In scenarios where resources change frequently, such as In high-frequency operation scenarios such as creating, mounting, and uninstalling virtual network cards, it is impossible to accurately deliver the configuration data of each computing node to the computing node, which reduces the credibility of the public cloud. Moreover, in the public cloud application scenario, when the number of computing nodes is large, the upper limit of Etcd's data storage may not meet the scenario requirements.

And in the above two schemes, after the intermediate module receives the configuration data, it stores the configuration data in the local storage module. After the configuration data is cleaned, if the computing node needs to pull the data, the cleaned configuration data cannot be processed. Recovery, so that the computing node cannot obtain the configuration data, causing the computing node to be unable to configure virtual machine resources, reducing the credibility of the public cloud.

In order to alleviate the problems existing in the above solution, an embodiment of the present disclosure provides a network configuration delivery system, which is applied in a public cloud, and the system includes a control cluster, a configuration data storage cluster, a configuration channel service cluster, and a computing node cluster. By setting configuration data storage clusters to store incremental configuration data, the situation of configuration data loss is alleviated, and the security and reliability of the system are improved. For large-scale computing node clusters in public cloud scenarios, configuration data storage clusters Able to meet data storage needs. Set up the configuration channel service cluster. By caching the incremental configuration data, the computing node cluster can quickly pull data from the cached configuration data, improving the efficiency of data delivery; and for large-scale When computing node clusters, since there is no need for data synchronization among the cache modules in the configuration channel service cluster, the configuration channel service cluster can expand the service horizontally to meet the pull requirements of large-scale computing nodes and improve the performance of the public cloud. The degree of adaptation in the scene.

At the same time, when there is incremental configuration data required by the computing node cluster in the cache module, the computing node cluster can quickly obtain the required incremental configuration data; there is no incremental configuration data required by the computing node cluster in the cache module When , the required incremental configuration data can be obtained from the configuration data storage cluster, which improves the data transmission efficiency of the system on the basis of ensuring the security of the system.

It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

In order to facilitate understanding of the embodiments of the present disclosure, a system for delivering network configuration disclosed in the embodiments of the present disclosure is first introduced in detail. The system is applied in the public cloud scenario. Here, a brief description of the public cloud application scenario and the basic concepts in this application scenario is given.

VPC builds an isolated, self-configured and managed virtual network environment for resources on the cloud, in which different private networks are isolated from each other, and users can create and manage cloud resources such as cloud servers and load balancing in their own private networks.

Regions refer to different geographic regions where physical data centers are located. Intranets in different regions are completely isolated to maintain maximum stability and fault tolerance among different regions. When creating a cloud resource, you must select the region where the cloud resource is to be created. The region cannot be modified after the resource is created.

Availability Zone (AZ) refers to the physical area where circuits and networks are isolated in the same area. In the same private network, the internal network between availability zones communicates with each other by default. When creating some cloud resources (subnets, cloud server instances), you need to select an availability zone. After the resources are created, the availability zone does not support modification.

In the public cloud scenario, the physical server resources of the public cloud are generally set in multiple regions, with 2-3 availability zones in each region, and 10,000 to 20,000 physical servers deployed in each availability zone. Generally, in public cloud scenarios, the scale of computing node clusters under a single VPC may reach 50,000 to 100,000, which shows that the number of computing nodes in public cloud scenarios is relatively large.

Referring to FIG. 1 , it is a schematic diagram of the architecture of the network configuration distribution system provided by the embodiment of the present disclosure, including: a control cluster 11, a configuration data storage cluster 12, a configuration channel service cluster 13, and a computing node cluster 14; wherein, the control cluster 11 is respectively connected to the configuration data storage cluster 12 and the configuration channel service cluster 13; the configuration channel service cluster 13 is connected to the computing node cluster 14.

The control cluster 11 is used to receive the incremental configuration data for the virtual switch on the computing node, send the incremental configuration data and the channel parameters generated for the incremental configuration data to the configuration data storage cluster 12 for associated storage, and store the incremental The configuration data and the channel parameters generated for the incremental configuration data are sent to the configuration channel service cluster 13 for caching.

Configuration channel service cluster 13 is used to receive the target channel parameters sent by the computing node cluster; in response to receiving the target channel parameters, from the cached configuration data, obtain the current configuration data matching the target channel parameters; from the cached configuration data When the current configuration data is obtained, the current configuration data is sent to the computing node cluster; when the current configuration data is not obtained from the cached configuration data, the current configuration data is obtained from the configuration data storage cluster, and the current configuration data is processed cache.

The computing node cluster 14 is configured to periodically send target channel parameters to the configuration channel service cluster and receive current configuration data; and configure virtual network resources on the virtual switch based on the current configuration data.

The control cluster can be a cluster composed of at least one server. The control cluster is used to receive the incremental configuration data for the virtual switch on the computing node delivered by the user, and generate corresponding channel parameters for the incremental configuration data. The received The incremental configuration data and the channel parameters corresponding to the incremental configuration data are sent to the configuration data storage cluster and the configuration channel service cluster. The configuration data storage cluster associates and stores the received incremental configuration data and channel parameters. And the configuration channel service cluster caches the received incremental configuration data and channel parameters. Wherein, the incremental configuration data is data issued by the user for configuring virtual machine resources in the computing node cluster, for example, the incremental configuration data may be configuration data for creating a network card, and the like.

The computing node cluster is used to periodically pull the required configuration data from the configuration channel service cluster, wherein the acquisition cycle of the computing node cluster can be set according to the actual situation. During implementation, the computing node cluster is used to generate target channel parameters and send the target channel parameters to the configuration channel service cluster. For example, the target channel parameter may include the name of the computing node, the channel version number of the data, the channel name of the configuration channel used when the data is delivered, the quantity of acquired configuration data, and the like.

The configuration channel service cluster receives the target channel parameters sent by the computing node cluster, and in response to receiving the target channel parameters, preferentially obtains the current configuration data matching the target channel parameters from the cached configuration data. If the current configuration data is obtained from the cached configuration data, the current configuration data is sent to the computing node cluster.

Due to the timeliness of the configuration data cached in the configuration channel service cluster, the configuration data may be deleted when the cached configuration data has not been pulled for a long time, so the current configuration data may not be obtained from the cached configuration data. If the current configuration data is not obtained from the cached configuration data, the current configuration data can be obtained from the configuration data storage cluster, and the obtained current configuration data can be cached so that the computing node cluster can be based on the target channel parameters in the next cycle , the current configuration parameters can be obtained from the configuration data cached in the configuration channel service cluster.

In an optional implementation manner, as shown in FIG. 2, the configuration data storage cluster 12 includes an incremental configuration storage module 121 and a full configuration storage module 122; the control cluster 11 is also used to receive the full configuration for the virtual switch on the computing node data, sending the full configuration data to the configuration data storage cluster 12; wherein, the incremental configuration data and the full configuration data are used to configure virtual network resources on the virtual switches of the computing nodes in the computing node cluster.

The configuration data storage cluster 12 is used to store the full configuration data to the full configuration storage module 122; store the incremental configuration data to the incremental configuration storage module 121, and use the incremental configuration data to store the full configuration data in the storage module. The full amount of configuration data is updated.

The control cluster is also used to receive the full configuration data delivered by the user, and deliver the full configuration data to the configuration data storage cluster. The configuration data storage cluster stores the full configuration data in the full configuration storage module, and stores the received incremental configuration data in the incremental configuration storage module. At the same time, when the incremental configuration data is received, the incremental configuration data can also be used to update the full configuration storage module, that is, the incremental configuration data is stored in the full configuration storage module, so as to realize the update of the full configuration storage module. For example, when the received incremental configuration data is: configuration data 3.1, and the full configuration data stored in the full configuration storage module includes: configuration data 1.1 and configuration data 2.1, the incremental configuration data is used to update the full configuration storage module Afterwards, the full configuration data stored in the updated full configuration storage module (that is, the updated full configuration data) is: configuration data 1.1, configuration data 2.1, and configuration data 3.1.

Exemplarily, the incremental configuration storage module may be a relational database management system MySQL, and the full configuration storage module may be Etcd. By using MySQL to store incremental configuration data, the current configuration data in the configuration process is stored, and Etcd is used to store the full configuration data, which realizes the storage of each configuration data in the configuration process. The above configuration meets the requirements It meets the needs of multiple application scenarios, and can accurately determine the distribution and current status of configuration data, improving the efficiency and accuracy of configuration.

By storing the incremental configuration data in the incremental configuration storage module and storing the full configuration data in the full configuration storage module, the classified storage of configuration data is realized, so that when the current configuration data cannot be found in the configuration channel service cluster, Obtaining the current configuration data from the configuration data storage cluster alleviates the problem of data loss in related technologies; and stores the incremental configuration data through the incremental configuration storage module, realizing the storage of the current configuration data in the configuration process, through the full configuration The storage module stores the full amount of configuration data, realizing the storage of each configuration data in the configuration process.

At the same time, store the full configuration data in the full configuration storage module. When the configuration status of the computing node is slow, for example, the version of the incremental configuration data stored in the incremental configuration storage module is 5.1, and the incremental configuration data received by the computing node The version of the data is 1.1. At this time, the configuration status of the computing nodes is slow. By sending the full configuration data to the computing node cluster, the fast configuration of the computing nodes is realized and the configuration efficiency is improved.

During implementation, when updating the full configuration storage module, the following situations exist: the incremental configuration data is successfully written to the incremental configuration storage module, but the incremental configuration data is not successfully written to the full configuration storage module. In order to ensure the full The data consistency between the configuration storage module and the incremental configuration storage module, the control cluster can control the incremental configuration storage module, delete the written incremental configuration data, and improve the security and reliability of the system.

In an optional implementation manner, as shown in FIG. 2 , the control cluster includes at least one private network VPC controller; each private network controller is provided with a private network VPC proxy broker software development kit (Software Development Kit, SDK).

The control cluster 11 sends the incremental configuration data and the channel parameters generated for the incremental configuration data to the configuration data storage cluster for associated storage, and sends the incremental configuration data and the channel parameters generated for the incremental configuration data to the configuration When the channel service cluster performs caching, it is used to:

Use the VPC broker SDK to put the incremental configuration data into the configuration channel that matches the incremental configuration data, and use the VPC broker SDK to update the channel version number of the configuration channel, where the configuration channel is associated with a channel version number, and the configuration channel Every time an incremental configuration data is added, the channel version number is increased by the preset value; and the incremental configuration data and the updated channel version number are sent to the configuration data storage cluster through the configuration channel for associated storage, and the incremental configuration is sent through the configuration channel The data and the updated channel version number are sent to the configuration channel service cluster for caching.

During implementation, the configuration channel channel can be set in the VPC broker, and the configuration channel can be set with at least one of the following rules: different types of configuration data are put into different configuration channels; the configuration channel maintains a channel version number (channel version number The initial value of can be a preset value, for example, the default value is 1), every time an incremental configuration data is added in the configuration channel, the channel version number associated with the configuration channel will increase the preset value (for example, add 1); the configuration channel maintains the incremental configuration data Incremental configuration data and full configuration data, among which, the incremental configuration data and full configuration data can be put into the configuration channel by the user of the VPC controller; the configuration channel sends the incremental configuration data in the channel to the Computing node; when the configuration channel determines that the incremental configuration data on the computing node is relatively old (for example, the channel version number of the current incremental configuration data reported by the computing node is much smaller than the channel version number of the latest incremental configuration data issued by the user) , to deliver the full amount of configuration data to the computing nodes, so that the configuration of the computing nodes can quickly catch up with the latest incremental configuration data delivered by the user.

In an optional implementation, the configuration channel includes the following types: the first configuration channel that stores the private network identification number (i.e. vpc_id) that the computing node server pays attention to; The second configuration channel; the third configuration channel for storing global events under each private network; the fourth configuration channel for storing target events concerned by at least one computing node under each private network.

For the first configuration channel, the channel type of the first configuration channel can be node_vpc_control_channels. The function of the first configuration channel can be: store the vpc_id that each computing node needs to pay attention to, and the stored virtual switch resources can include: resources related to VPC Data, control information of some computing nodes, resource data related to VPC, such as subnet resource data, security group resource data, routing table resource data, etc.; wherein, the first configuration channel is equivalent to the signaling channel of the computing node. The number of first configuration channels is related to the number of computing nodes. Generally, one computing node corresponds to one first configuration channel, that is, the number of first configuration channels can be num (computing node host). The channel name of the first configuration channel can be determined according to the set rules. For example, the naming rule of the channel name of the first configuration channel can be: "control"+"host ip", where the host ip can be the Internet connection of the computing node Protocol (Internet Protocol, IP) address, for example: the channel name of the first configuration channel may be "control+10.2.3.4".

For the second configuration channel, the channel type of the second configuration channel can be: vpc_host_data_channels, and the function of the second configuration channel can be: store single-node events under a certain VPC that each computing node needs to pay attention to, and store virtual switch resources It may include: virtual port vport, elastic public IP (Elastic IP Address, EIP), high-availability virtual IP (High-Availability Virtual IP Address, HaVip), etc. The number of second configuration channels is related to the number of VPCs under the computing nodes. Generally, each VPC under each computing node corresponds to a second configuration channel, that is, the number of second configuration channels can be num(VPC)×num(host) . The channel name of the second configuration channel can be determined according to the set rules. For example, the naming rule of the channel name of the second configuration channel can be: "host_channel"+{vpc_id}+{host ip}, for example: host_channel+vpc-mjnipf8wjy +10.2.3.4".

For the third configuration channel, the channel type of the third configuration channel can be: vpc_global_data_channels, the role of the third configuration channel can be: to store global events under each VPC, and the stored virtual switch resources can include: routing table route, etc. . The number of third configuration channels is related to the number of VPCs. Generally, each VPC corresponds to one third configuration channel, that is, the number of third configuration channels may be num(VPCs). The channel name of the third configuration channel can be determined according to the set rules. For example, the naming rule of the channel name of the third configuration channel can be: "selfdefine"+{vpc_id}+{service type}, for example: selfdefine+vpc-mjnipf8wjy +route".

For the fourth configuration channel, the channel type of the fourth configuration channel can be: vpc_mutil_host_data_channels. The function of the fourth configuration channel can be: to store target events that need to be paid attention to by multiple computing nodes under the VPC. The stored virtual switch resources can include: Security group rules, IP address set IPset, network access control list (Access Control List, ACL), etc. The number of the fourth configuration channel is related to the number of computing nodes concerned with the target event. For example, if the target event is a channel creation event and the number of computing nodes concerned with the target event is n, then the number of the fourth configuration channel is n. The name of the fourth channel is related to the target event. For example, the name of the fourth configuration channel is constructed by obtaining the corresponding creation and deletion event (target event) from the second configuration channel, that is, the virtual switch control layer controller is obtained from the second configuration channel. Obtain the corresponding creation and deletion event (target event), and automatically go to the fourth configuration channel corresponding to the watch.

Referring to the channel relationship diagram shown in FIG. 3 , the figure shows the relationship among the first configuration channel, the second configuration channel, the third configuration channel and the fourth configuration channel. During specific implementation, the configuration data can be put into the first configuration channel, so that the computing node can obtain the vpc id that needs attention. When performing a VPC creation operation or a VPC deletion operation, if there is a single-node event in the VPC, the configuration data corresponding to the single-node event can be delivered by using the second configuration channel. If there is a global event in the VPC, the configuration data corresponding to the global event can be delivered through the third configuration channel. If there are target events in the VPC that require the attention of some computing nodes, the fourth configuration channel related to the target event corresponding to some computing nodes can be determined from the second configuration channel, and the configuration data corresponding to the target event can be downloaded through the fourth configuration channel. hair.

In this solution, by setting multiple types of configuration channels, different incremental configuration data can be sent to the computing node cluster more quickly and conveniently through different configuration channels. For example, global events can be downloaded through the third configuration channel. It is sent to each computing node corresponding to the VPC, which improves the efficiency of data delivery.

Since the configuration channel is set in the VPC broker, you can use the VPC broker SDK to put the incremental data into the configuration channel that matches the incremental configuration data. For example, when the incremental configuration data is a single-node event under VPC1, you can add the incremental The volume configuration data is put into the second configuration channel corresponding to VPC1. And use the VPC broker SDK to update the channel version number of the configuration channel, that is, add the preset value to the channel version number of the configuration channel to get the updated channel version number.

Then associate the incremental configuration data with the updated channel version number corresponding to the configuration channel, and send the associated incremental configuration data and the updated channel version number to the configuration data storage cluster and the configuration channel service cluster through the configuration channel, so that The configuration data storage cluster stores the received associated incremental configuration data and the updated channel version number to the incremental configuration storage module, and the configuration channel service cluster will receive the associated incremental configuration data and the updated channel The version number is cached in the cache module. In the subsequent process, the configuration channel service cluster can obtain the current configuration data from the cache module according to the received target channel parameters (such as channel name and channel version number).

Here, the incremental configuration data is delivered through the configuration channel to achieve faster delivery of the incremental configuration data, and each configuration channel maintains a channel version number, so that the computing nodes can compare Accurately obtain the required configuration data.

During implementation, the VPC controller can also periodically detect the status of each configuration channel; delete the configuration channel whose status is indicated as invalid, and reserve the configuration channel whose status is indicated as valid. For example, when the VPC corresponding to the configuration channel does not exist and the computing node server corresponding to the configuration channel goes offline, it may be determined that the status of the configuration channel is invalid. By periodically deleting invalid configuration channels, the occupation of network resources by invalid configuration channels can be reduced, and resource waste can be avoided.

Referring to the access process of the VPC controller shown in FIG. 4 , the functions of the VPC controller will be described in conjunction with FIG. 4 . The Hydra in the VPC controller is responsible for creating/deleting the configuration channel channel. When receiving the incremental configuration data, it can use the created configuration channel to send the incremental configuration data to the incremental configuration storage module MySQL by calling the API, and Send the incremental configuration data to the full configuration storage module Etcd through the configuration channel to update Etcd, so that there is data consistency between the incremental configuration storage module and the full configuration storage module; when receiving the full configuration data, Write the full configuration data to Etcd through the configuration channel. At the same time, the VPC broker can be notified, so that the VPC broker can use the VPC broker SDK to write incremental configuration data to the VPC broker server, and can also regularly clean up expired channels, such as deleting the channel when the status of the channel is determined to be invalid.

In an optional implementation manner, as shown in FIG. 2 , the configuration channel service cluster includes at least one configuration channel server, and each configuration channel server row is provided with a private network proxy service VPC broker server module and a cache module Redis.

The control cluster is used to send incremental configuration data to each configuration channel server in the configuration channel service cluster. The VPC broker server module in each configuration channel server is used to receive incremental configuration data and cache the incremental configuration data to the cache module of the configuration channel server.

When multiple configuration channel servers are included in the configuration channel service cluster, considering that computing nodes may pull incremental configuration data from any configuration channel server, the control cluster needs to broadcast incremental configuration data to each configuration channel server. During implementation, the control cluster is used to send incremental configuration data to each configuration channel server in the configuration channel service cluster. When the VPC broker server module in each configuration channel server receives the incremental configuration data, it caches the incremental configuration data to the cache module of the configuration channel server.

The number of configuration channel servers in the configuration channel service cluster can be expanded. During implementation, the configuration channel server can be expanded horizontally so that the configuration channel service cluster can meet the needs of the computing node cluster and improve the efficiency of data transmission.

In the embodiment of the present disclosure, at least one configuration channel server is set in the configuration channel service cluster, and each configuration channel server row is provided with a VPC broker server module and a cache module, and the target channel parameters are received by the VPC broker server module and cached in the cache module. Incremental configuration data enables computing nodes to quickly obtain incremental configuration data from the configuration channel server, improving data transmission efficiency.

During implementation, the system may also include a load balancer; the load balancer is respectively connected to the configuration channel service cluster and the computing node cluster. The load balancer is used to determine the configuration channel server corresponding to the computing node from each configuration channel server included in the configuration channel service cluster when receiving the target channel parameter sent by any computing node in the computing node cluster; and send the target channel parameter to For the VPC broker server module that determines the configured channel server.

The VPC broker client module on any computing node in the computing node cluster can establish a transmission control protocol (Transmission Control Protocol, TCP) long connection with any configuration channel server in the configuration channel service cluster through the load balancer. Report the local channel version number version of the concerned configuration channel, so that the VPC broker server module can obtain and deliver version+1 to version+N from the cache module according to the version of the configuration channel channel reported by the VPC broker client module (N is preset amount) of incremental configuration data.

In an optional implementation manner, as shown in FIG. 2, the computing node cluster includes at least one computing node server, each computing node server includes a node controller, and a private network agent client VPCbroker client module is included in the node controller;

The VPC broker client module is used to: determine the target channel parameters according to the channel name and channel version number of the stored configuration channel; send the target channel parameters to the configuration channel service cluster; and verify the current configuration data after receiving the current configuration data Whether the associated channel version number matches the target channel parameter, if so, store the channel version number, and configure the virtual network resource on the virtual switch based on the current configuration data. If it does not match, the data will be pulled again based on the target channel parameters.

During implementation, two coroutines can be started in the VPC broker client module, such as Report Channel ToBroker and Receive Channel From Broker. A TCP long connection can be used between the VPC broker client module and the VPC broker server module. Report Channel To Broker is responsible for delivering configuration data (incremental configuration data and full configuration data), and Receive Channel From Broker is responsible for receiving configuration data. When the VPC brokerclient receives the configuration data with the channel version number version, it will verify whether the version is correct. If it is correct, the configuration data will be transferred to the processing service response module through the callback CallBack function. The transferred configuration data is not associated with version.

As shown in FIG. 5, the VPC broker client module may include: a version storage module, a channel version management module, a version cycle reporting module, a processing service response module and an interface module. The channel version management module is used to determine the target channel parameters according to the channel name and channel version number of the configuration channel stored in the version storage module; and send the target channel parameters to the version cycle reporting module, so that the version cycle reporting module can report the target channel parameters Sent to the configuration channel service cluster. For example, the channel name and channel version number of the configuration channel stored in the version storage module are determined as target channel parameters. When the channel version number of the configuration channel does not exist in the version storage module, a target value such as -1 can be used as the target channel parameter, so that the VPC broker server can obtain and deliver the full amount of configuration data according to the target value.

The channel version management module is also used to check whether the channel version number associated with the current configuration parameters matches the target channel parameters after receiving the current configuration data. If it matches, it means that the current configuration data is correct, and the current configuration data is sent to the processing The service response module stores the channel version number associated with the current configuration data in the version storage module. The service response module configures the virtual network resources based on the current configuration data by calling the interface module. The version storage module can be a lightweight database SQLite.

Among them, the control cluster and computing node cluster may also include other functional modules required for virtual network resource configuration, such as computing node servers may also include virtual switches, virtual machines, etc., and other functional modules may be set as required during implementation.

In an optional implementation, the target channel parameters include the channel name and channel version number of the target configuration channel, and the configuration channel service cluster, in response to receiving the target channel parameters, obtains the configuration data that matches the target channel parameters from the cached configuration data. When using the current configuration data for:

According to the channel name, obtain the cached version number of the target configuration channel from the cached configuration data; when the cached version number is greater than the channel version number, determine the version number range based on the channel version number and the preset number; obtain the version number from the cache module The configuration data that matches the version number range; when the configuration data that matches the version number range is successfully obtained, the obtained configuration data is used as the current configuration data.

The target channel parameter may include the channel name and channel version number of the target configuration channel. After the configuration channel service cluster receives the target channel parameter, it can obtain the cache version number of the target configuration channel from the cache module according to the channel name in the target channel parameter, and the cache version number is the latest version number of the target configuration channel.

Compare the channel version number in the target channel parameter with the cache version number. When the cache version number is greater than the channel version number, compared with the incremental configuration data received in the computing node, the increment of the target configuration channel in the cache module The configuration data is new incremental configuration data, so the version number range can be determined based on the channel version number and the preset number. For example, when the channel version number is version2.0 and the preset number is N, the version number range can be: version2.0+1 to version2.0+N. Then obtain the configuration data matching the version number range from the cache module, such as obtaining the configuration data corresponding to version2.0+1, the configuration data corresponding to version2.0+2, ..., the configuration data corresponding to version2.0+N in the target configuration channel configuration data. When the configuration data matching the version number range is successfully obtained, the obtained configuration data is used as the current configuration data.

Among them, the target channel parameters can also include the name of the computing node, the preset number, etc., so that the configuration channel service cluster can determine the version number range according to the preset number, and monitor various information in the system operation process according to the name of the computing node.

Here, the target channel parameter includes the channel name and channel version number of the target configuration channel, and the required current configuration data can be obtained more accurately through the target channel parameter. At the same time, by comparing the cache version number with the channel version number, it can be quickly and preliminarily judged whether the required incremental configuration data exists in the cache module.

In an optional implementation, the configuration channel service cluster is also used for: when the configuration data that matches the version number range is not successfully obtained from the cached configuration data, obtain the configuration data in the incremental configuration storage module in the storage cluster The minimum version number of the stored target configuration channel; determine whether the channel version number is less than the minimum version number; if so, obtain the full configuration data corresponding to the target configuration channel from the cached configuration data based on the target channel parameters; if the full configuration is successfully obtained data, the full configuration data will be used as the current configuration data; if the full configuration data cannot be obtained, the full configuration data corresponding to the target configuration channel will be obtained from the full configuration storage module in the configuration data storage cluster, and the full configuration data will be cached .

During implementation, when the cache version number is greater than the channel version number, there are cases where the configuration data matching the version number range is not successfully obtained from the cache module, for example, all incremental configurations corresponding to the version number range are not included in the cache module data, it may cause configuration data acquisition failure. In this case, the minimum version number of the target configuration channel stored in the incremental configuration storage module in the configuration data storage cluster can be obtained; the smaller the version number, the time when the incremental configuration data corresponding to the version number is put into the configuration channel sooner.

Then determine whether the channel version number is less than the minimum version number, if so, it means that the channel version number is too old, that is, the incremental configuration data received by the computing node may be the older incremental configuration data issued by the user earlier , at this time, the full amount of configuration data corresponding to the target configuration channel can be obtained from the cache module (that is, the cached configuration data) based on the target channel parameters. If the full amount of configuration data is successfully obtained, the full amount of configuration data will be used as the current configuration data, so that the computing node can quickly catch up with the user's control plane; The storage module obtains the full configuration data corresponding to the target configuration channel, and caches the full configuration data in the cache module, so that the computing node can obtain the full configuration data based on the target channel parameters next time.

When the channel version number is greater than or equal to the minimum version number, the maximum version number corresponding to the target configuration channel in the cache module and the maximum version number corresponding to the target configuration channel in the incremental configuration storage module can be obtained; when the maximum version number of the cache module is less than When the maximum version number of the incremental configuration storage module is used, it means that the incremental configuration data corresponding to the target configuration channel in the cache module does not include the latest incremental configuration data, and the incremental configuration data corresponding to the target configuration channel in the incremental configuration storage module can be , synchronized to the cache module.

When the maximum version number of the cache module is equal to the maximum version number of the incremental configuration storage module, it means that the incremental configuration data corresponding to the target configuration channel in the cache module has equalized the incremental configuration storage module, and the synchronization operation may not be performed.

During implementation, when comparing the cache version number with the channel version number, there may be a situation where the cache version number is equal to the channel version number. In this case, it means that the incremental configuration data of the target configuration channel in the computing node has equaled the vpc controller Delivered configuration data, you don't need to perform any operation at this time.

There may also be a case where the cache version number is smaller than the channel version number. In this case, the incremental configuration data cached by the cache module does not belong to the latest incremental configuration data. At this time, the maximum version number corresponding to the target configuration channel in the cache module can be obtained , and the maximum version number corresponding to the target configuration channel in the incremental configuration storage module; when the maximum version number of the cache module is less than the maximum version number of the incremental configuration storage module, the increment corresponding to the target configuration channel in the incremental configuration storage module The configuration data is synchronized to the cache module so that the computing node can obtain the current configuration data next time.

With reference to FIG. 6 , the process of obtaining the current configuration data matching the target channel parameters from the configuration data cached in the cache module will be described in detail. Configure the channel service cluster to receive the target channel parameters, that is, the input parameters: the name of the computing node, the channel version number, the channel name, and the preset quantity. Then obtain the cache version number of the target configuration channel from the cache module. Determine whether the cache version number is greater than the channel version number, and if so, go to the cache module to obtain the incremental configuration data corresponding to the channel version number + 1 to the channel version number + N, where N is the preset number. If the acquisition is successful, the incremental configuration data (that is, the incremental configuration data corresponding to channel version number + 1 to channel version number + N) will be returned. If the acquisition is not successful, then judge whether the channel version number is less than the minimum version number in the incremental configuration storage module, if so, obtain the full configuration data from the cache module, and return the full configuration data when the full configuration data is successfully obtained; if the full When the acquisition of configuration data fails, execute: 1. The miss process; 2. Obtain the full configuration data from the full configuration storage module and put it in the cache module. Among them, the miss process means that no data is returned to the computing node service cluster.

If the channel version number is greater than or equal to the minimum version number in the incremental configuration storage module, then execute: 1, miss process; 2, compare the maximum version number of the target configuration channel in the cache module and the incremental configuration storage module, if the cache module If the maximum version number falls behind, the data is synchronized from the incremental configuration storage module to the cache module. That is, compare the maximum version number of the target configuration channel in the cache module with the maximum version number of the target configuration channel in the incremental configuration storage module. If the maximum version number in the cache module is smaller than the maximum version number in the incremental configuration storage module, start from the incremental configuration The data in the storage module is synchronized to the cache module.

If the cache version number is equal to the channel version number, no processing is performed, which means that the incremental configuration data of the target configuration channel received on the computing node is the latest data, and no data pull is required. If the cache version number is smaller than the channel version number, execute: 1. miss process; 2. compare the maximum version number of the target configuration channel in the cache module and the incremental configuration storage module. Synchronize data in the volume configuration storage module to the cache module.
