Background
Currently, a pod can be deployed on a certain computing node, and then the creation process of a certain application program is completed. Specifically, a computing node (e.g., a target computing node) for deploying a pod may be determined from a Kubernetes system (hereinafter referred to as the K8s system). Illustratively, as shown in fig. 1, the K8s system 10 may include a control node 101, a computing node 102, a computing node 103, and a computing node 104. The control node 101 may select a compute node with a remaining computational resource greater than 0 and a highest priority from the compute nodes 102, 103, and 104. Assuming that the remaining computing resources of the above 3 computing nodes are all greater than 0, and the priority of the computing node 104 is higher than the priority of the computing node 103 and the priority of the computing node 102, the control node 101 may determine that the computing node 104 is the target computing node, i.e., determine that a pod is deployed in the computing node 104.
However, the above-described method based on the remaining computing resources of the computing nodes and the priorities of the computing nodes may not be effective in determining the appropriate target computing node. For example, the computing node 104 determined above may not be able to complete the deployment process of the pod for some reason, and may not be able to complete the creation process of the application, affecting the user experience.

In conjunction with the communication system shown in fig. 2, the service access method provided by the embodiment of the present invention is completely described below from the perspective of interaction between devices in the communication system.
As shown in fig. 4, the service access method provided by the embodiment of the present invention may include S101 to S111.
S101, the main control node receives a service access request sent by UE.
The service access request comprises a requirement index corresponding to a target service, and the service access request is used for requesting to determine at least one target computing node corresponding to the target service.
Specifically, the user may create the service access request on the UE through the Yaml configuration script, and the UE sends the service access request to the main control node, so that the main control node may receive the service access request.
It should be understood that the target service is one of a plurality of services (or service functions) corresponding to a certain application, the target service may correspond to a plurality of processes, one process corresponds to (or becomes by encapsulation) one pod, and one pod is created in order to run the process corresponding to the pod. That is, the target service may correspond to a plurality of pods, and the at least one target computing node is configured to create the plurality of pods, and specifically, each computing node of the at least one target computing node may create at least one of the plurality of pods.
In the embodiment of the present invention, the requirement index corresponding to the target service is an index required for creating the target service (specifically, creating a pod), and the index may include a network requirement index and a resource requirement index. Specifically, the network requirement index is a network index required in a routing process, and includes a maximum delay of a target service (e.g., 10 milliseconds (ms)); the resource requirement index is a resource index required for creating the target service, and includes a type (for example, CPU) of a computing resource required for creating the target service and a requirement value (for example, 1GB) corresponding to the computing resource.
S102, the master node sends a container scheduling indication message to the translator.
Wherein, the container scheduling indication message includes a requirement index corresponding to the target service.
It should be understood that the master node is a control node in the K8s system, and the instruction (i.e. the container scheduling indication message) created in the K8s system by the user is in a passing text format visible to the user, and at this time, the master node needs to send the container scheduling indication message to the translator, so that the translator can parse the instruction and translate the content in the instruction into the language (or a script that can be executed) corresponding to the network device (e.g. the routing device and the computing node), thereby completing the creation process of the target service.
S103, the translator receives a container scheduling indication message sent by the master node.
S104, the translator determines a deployment strategy corresponding to the target service according to the requirement index corresponding to the target service, the network quality condition of the multiple pieces of routing equipment and the resource operation condition of the computing node corresponding to each of the multiple pieces of routing equipment.
It should be understood that a plurality of routing devices may correspond to a plurality of computing nodes, and the routing device may actively report the network quality condition and the resource operation condition of each of the plurality of computing nodes corresponding to the routing device to the translator. Specifically, the network quality condition is used to characterize relevant parameters of the number of routing devices in the network, including delay, jitter, next hop device, quality of service (QoS), quality of experience (QoE), and the like of the number of routing devices; the resource operation condition of a computing node is used to characterize the computing or storage capability of the computing node, and may specifically include a type of the computing resource (e.g., a CPU or a Graphics Processing Unit (GPU)), a remaining resource amount of the computing node, and the like.
It can be understood that the deployment policy is a principle target required for creating the target service, that is, a resource operation condition of a computing node (i.e., a target computing node) that creates the target service and a network quality condition of a number path routing device (hereinafter referred to as a target number path routing device) corresponding to the computing node need to satisfy an index included in the deployment policy.
In an implementation manner of the embodiment of the present invention, the deployment policy may include a delay range corresponding to the target service and a minimum resource amount corresponding to the target service, where a maximum value in the delay range is less than or equal to a maximum delay of the target service, and the minimum resource amount is greater than or equal to a required value corresponding to the computing resource. In the subsequent application process, the delay of the target number routing device should satisfy the delay range, and the remaining resource amount of the target computing node should be greater than the minimum resource amount.
In this embodiment of the present invention, the translator may determine, according to a requirement index corresponding to the target service, a network quality condition of the multiple pieces of routing equipment, and a resource operation condition of a computing node corresponding to each piece of routing equipment in the multiple pieces of routing equipment, a deployment policy corresponding to the target service, so that the routing equipment (including the main routing equipment and the number of routing equipment) may determine, based on the deployment policy, a next N-hop equipment (N ≧ 1), and determine the target computing node from the multiple computing nodes corresponding to the next N-hop equipment.
S105, the translator sends the demand index corresponding to the target service and the deployment strategy corresponding to the target service to the main routing device.
S106, the main routing device receives the demand index corresponding to the target service and the deployment strategy corresponding to the target service, wherein the demand index is sent by the translator.
S107, the main routing equipment determines the next hop of digital channel routing equipment based on the demand index corresponding to the target service, the deployment strategy corresponding to the target service and the optimal path algorithm.
In an implementation manner of the embodiment of the present invention, the main routing device may first select, from a plurality of number path routing devices having a communication relationship, a plurality of number path routing devices that satisfy a requirement indicator (hereinafter referred to as a first condition) corresponding to a target service, then select, from the plurality of number path routing devices that satisfy the first condition, a plurality of number path routing devices that satisfy a deployment policy (hereinafter referred to as a second condition) corresponding to the target service, and determine, in combination with an optimal routing algorithm, the number path routing device of the next hop from the plurality of number path routing devices that satisfy the second condition.
For example, table 1 below is an example of network quality of 5 number of path-driven devices corresponding to the main routing device.
TABLE 1
| Digital channel routing device | Priority of devices | Time delay |
| Digital channel routing device 1 | Height of | 10ms |
| Digital channel routing device 2 | Height of | 5ms |
| Digital channel routing device 3 | Height of | 3ms |
| Digital path routing device 4 | In | 2ms |
| Digital channel routing device 5 | In | 5ms |
Assuming that the demand index corresponding to the target service includes that the priority of the target number of routing devices is high, and the delay range included in the deployment policy corresponding to the target service is (0,5 ms), the main routing device may determine that the number of routing devices 2 and the number of routing devices 3 are the number of routing devices that satisfy the second condition, and further may determine, based on an optimal path algorithm, the number of routing devices of a next hop from the 2 number of routing devices.
And S108, the main routing equipment sends the demand index corresponding to the target service and the deployment strategy corresponding to the target service to the next-hop digital channel routing equipment, so that the next-hop digital channel routing equipment determines whether the target computing node exists in the plurality of computing nodes to be identified.
And the plurality of computing nodes to be identified are computing nodes corresponding to the next hop of digital access routing equipment.
S109, the first number of paths of routing equipment receives the demand index corresponding to the target service sent by the main routing equipment and the deployment strategy corresponding to the target service.
It will be appreciated that the first number of ways routing device is the next hop number of ways routing device described above.
S110, determining whether a target computing node exists in the plurality of computing nodes to be identified by the first number of paths based on the demand index corresponding to the target service and the deployment strategy corresponding to the target service.
In an implementation manner of the embodiment of the present invention, the requirement index corresponding to the target service includes a type of a computing resource required for creating the target service, and the deployment policy corresponding to the target service includes a minimum resource amount corresponding to the target service.
In the embodiment of the present invention, when the operating condition of the first to-be-identified computing node meets the requirement index corresponding to the target service and the deployment policy corresponding to the target service, the first number of path routing devices may determine that the plurality of to-be-identified computing nodes exist in the target computing node, and the first number of path routing devices may also determine that the first to-be-identified computing node is the target computing node, where the first to-be-identified computing node is one of the plurality of to-be-identified computing nodes.
For example, table 2 below is an example of the respective operating conditions of the plurality of to-be-identified computing nodes corresponding to the first number of path-limited devices.
TABLE 2
| To-be-identified computing node | Type of computing resource | Amount of remaining resources |
| To-be-identified computing node 1 | GPU | 5G |
| To-be-identified computing node 2 | GPU | 10G |
| To-be-identified computing node 3 | CPU | 10G |
Assuming a requirement index corresponding to the target service (specifically, the type of the computing resource required by the target service is GPU), and a deployment strategy corresponding to the target service (specifically, the minimum resource amount corresponding to the target service is 4G), the first number of paths are determined by the device to have the target computing node, specifically, the computing node 1 to be identified may be determined as the target computing node, and the computing node 2 to be identified may also be determined as the target computing node.
Optionally, in a case that the operation conditions of the at least two to-be-identified computing nodes meet the requirement index corresponding to the target service and the deployment policy corresponding to the target service, the first number of pass-by devices may further select one target computing node from the at least two to-be-identified computing nodes according to the respective operation conditions (specifically, the remaining resource amount) of the at least two to-be-identified computing nodes, and for example, the to-be-identified computing node with the largest remaining resource amount may be determined as the target computing node.
And S111, under the condition that a target computing node exists in the plurality of computing nodes to be identified, the first number of paths send the demand indexes corresponding to the target service to the target computing node by the equipment.
To this end, the target computing node may start to create a pod corresponding to the target service, and allocate a corresponding computing resource to the pod based on the demand index corresponding to the target service.
In the service access method provided by the embodiment of the present invention, a main control node receives a service access request sent by a UE, where the service access request includes a requirement index corresponding to a target service, and then the main control node sends a container scheduling indication message to a translator; after receiving the container scheduling indication message, the translator may determine a deployment policy corresponding to the target service according to a requirement index corresponding to the target service, network quality conditions of multiple pieces of routing equipment, and resource operation conditions of computing nodes corresponding to the multiple pieces of routing equipment, and then the translator may send the requirement index corresponding to the target service and the deployment policy corresponding to the target service to the main routing equipment; after receiving the demand index and the deployment policy, the main routing device may determine, based on the demand index, the deployment policy, and an optimal path algorithm, a digital-to-access routing device of a next hop, and then the main routing device sends the demand index and the deployment policy to the digital-to-access routing device of the next hop, so that the digital-to-access routing device of the next hop determines whether a target computing node exists in a plurality of computing nodes to be identified (i.e., computing nodes corresponding to the digital-to-access routing device of the next hop). In the embodiment of the invention, the target computing node (i.e. the computing node for creating the target service, specifically the pod corresponding to the target service) and the target number access routing device corresponding to the target computing node can be determined based on the requirement index, the deployment strategy and the optimal path algorithm, so that the target computing node can be accurately and reasonably determined, the creating efficiency of the pod and the target service is improved, and the effectiveness of service access is further improved.
As shown in fig. 5, in an implementation manner, after S101, the service access method provided in the embodiment of the present invention may further include S201 to S207.
S201, the main control node sends an information acquisition request to the translator.
The information obtaining request is used for requesting to obtain the network quality conditions of the plurality of digital channel routing devices and the resource operation conditions of the computing nodes corresponding to the plurality of digital channel routing devices.
S202, the translator receives an information acquisition request sent by the master control node.
S203, the translator sends, to the master node, the network quality condition of the multiple routing devices and the resource operation condition of the computing node corresponding to each of the multiple routing devices.
S204, the main control node receives the network quality condition of the plurality of routing devices and the resource operation condition of the computing node corresponding to each of the plurality of routing devices, wherein the network quality condition is sent by the translator.
S205, the main control node determines the priority corresponding to the target service based on the requirement index corresponding to the target service, the network quality condition of the multiple pieces of routing equipment and the resource operation condition of the computing node corresponding to each of the multiple pieces of routing equipment, and adds identification information to the target service.
It should be understood that one identification information corresponds to one service, and the master node adds the identification information to the target service, i.e. so that the subsequent device can determine the service type of the target service based on the identification information.
Optionally, the requirement index may include a delay requirement and a resource requirement, and the master control node may determine a service with a lower delay requirement and/or a higher resource requirement as a high-priority service; the service with better network quality (for example, the average delay of a plurality of routing devices is lower) and/or better resource operation (for example, the average remaining resource amount of a plurality of computing nodes is larger) can also be determined as the high-priority service. In the embodiment of the present invention, the master control node may determine, as an example, a service with a low delay requirement, a low average delay, and a large average remaining resource amount as a high priority service, and determine other services as low priority services, based on the above three information.
S206, the main control node sends the priority corresponding to the target service and the identification information of the target service to the translator.
S207, the translator receives the priority corresponding to the target service and the identification information of the target service sent by the master node.
It can be understood that, the translator may receive the priority corresponding to each of the multiple services sent by the master node and the identification information of each of the multiple services, so that a target service may be preferentially forwarded based on the priority corresponding to each of the multiple services and the identification information of each of the multiple services, and further, when the target service is a high-priority service, the target routing device may preferentially receive or forward the relevant information of the target service, and the target computing node may preferentially allocate resources to the target service and preferentially create the target service.
In the service access method provided by the embodiment of the invention, after receiving a service access request sent by the UE, the master control node may send an information acquisition request to the translator; after receiving the information acquisition request, the translator sends network quality conditions of a plurality of digital channel routing devices and resource operation conditions of computing nodes corresponding to the digital channel routing devices to the main control node; the main control node determines the priority corresponding to the target service based on the requirement index corresponding to the target service, the network quality condition of the multiple pieces of routing equipment and the resource operation condition of the computing node corresponding to each of the multiple pieces of routing equipment, adds identification information for the target service, and sends the priority corresponding to the target service and the identification information of the target service to the translator. In this embodiment of the present invention, after receiving the priority and the identification information, the translator may determine a forwarding or processing order corresponding to the target service based on the priority and the identification information. Specifically, when the target service is a high-priority service, the target number access routing device may preferentially receive or forward the related information of the target service, and the target computing node may preferentially create the target service (i.e., the pod corresponding to the target service), so that computing resources may be reasonably allocated, and the efficiency of data forwarding is improved.
As shown in fig. 6, the service access method provided in the embodiment of the present invention may further include S301-S306.
S301, the first target computing node sends the service information of the first pod to the main control node.
The first pod is one of a plurality of pods corresponding to a target service, and the service information of the first pod includes a virtual Internet Protocol (IP) address of the first pod, port information corresponding to the first pod, and a service identifier of the target service, where the service identifier is used to identify a service type of the target service.
It should be appreciated that the first target computing node is the computing node that created the first pod, and that the first target computing node may assign a virtual IP address and port information for the first pod. And after the first pod is created, the first target computing node may send service information of the first pod to a master node, and further, other pods may interact with the first pod based on the virtual IP address and the port information.
Specifically, a sdec module may be included in one of the computing nodes, and after the first pod is created, the first pod may send the virtual IP address and the port information to the sdec module, and the sdec module performs cell broadcasting.
S302, the main control node receives the service information of the first pod sent by the first target computing node.
S303, the main control node inquires other target calculation nodes from the etcd database based on the service identification of the target service.
And the other target computing nodes are computing nodes except the first target computing node in at least one target node corresponding to the target service.
It should be understood that the etcd database is a key-value pair storage system. In the embodiment of the invention, the association relation and the mapping relation of each pod in the plurality of pods can be stored in the etcd database. Taking the first pod as an example, the etcd database may store an association relationship of the first pod and a mapping relationship of the first pod, where the association relationship is used to characterize which pods belong to the same service (i.e., a target service) as the first pod, and the mapping relationship is used to characterize which computing node (i.e., a first target computing node) the first pod belongs to.
Optionally, the master node may further send the service information of the first pod to the etcd database, so that the etcd database may store and backup the content included in the service information.
S304, the master node broadcasts the service information of the first pod in the target cluster.
The target cluster is a cluster formed by the first target computing node and the other target computing nodes, that is, the main control node sends the service information of the first pod to the other target nodes respectively.
S305, the second target computing node receives the service information of the first pod sent by the main control node.
With reference to the description of the foregoing embodiment, it should be understood that the service information of the first pod includes a virtual IP address of the first pod, port information corresponding to the first pod, and a service identifier of the target service, and the second target computing node is one of the other target computing nodes.
S306, under the condition that the second target computing node comprises the second pod, the second target computing node sends a service creation request to the first target computing node.
The second pod is a pod other than the first pod in the plurality of pods corresponding to the target service, and the service creation request includes data corresponding to the second pod.
It should be understood that the second target computing node includes the second pod, which indicates that the second target computing node is also a computing node corresponding to the target service, that is, the creation of the target service requires the cooperative processing between the second target computing node (specifically, the second pod) and the first target computing node (specifically, the first pod), so that the second target computing node can send data corresponding to the second pod to the first target computing node, and reach the first pod through the specific IP address inside the first target computing node (i.e., the virtual IP address of the first pod) and the port information (the port information corresponding to the first pod), thereby completing the creation process of the target service.
Alternatively, the service creation request may arrive at the first pod via the sidecar module described above.
In the service access method provided by the embodiment of the present invention, a first target computing node sends service information of a first pod to a main control node, where the service information includes a virtual IP address of the first pod, port information corresponding to the first pod, and a service identifier of a target service; after receiving the service information, the master node may query other target computing nodes from the etcd database based on the service identifier of the target service, and broadcast the service information in a target cluster (i.e., a cluster formed by the first target computing node and other target computing nodes). After receiving the service information, the second target computing node (i.e., one of the other target computing nodes) sends a service creation request to the first target computing node if it is determined that the second target computing node includes the second pod, so that the creation process of the target service can be completed. In the embodiment of the present invention, the master control node may receive and broadcast the service information of the first pod in the target cluster, and then the target computing node (i.e., the second target computing node) corresponding to the other pod (including the second pod) corresponding to the target service may send the service creation request to the first target computing node, thereby completing the creation process of the target service, and being capable of reasonably determining the other target computing node, thereby improving the efficiency of service creation.
