Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art based on this application belong to the scope of protection of this application.

With the widespread application of AI (Artificial Intelligence, artificial intelligence) and 5G technologies, emerging services such as the Internet of Things, big video, and Internet of Vehicles are booming. The existing network architecture and cloud centralized deployment methods are difficult to meet business needs. Therefore, through Edge computing enables networks and clouds to migrate to the edge along with business flows, which has become a new trend in the industry.

In related technologies, from a network perspective, resources of a single edge site are limited, and coordination among multiple edge sites is lacking. From a business perspective, the application layer is decoupled from the network layer, and the business cannot perceive the network status. Therefore, in order to improve the quality of network services, the network architecture needs to consider the evolution of network and computing convergence, and realize the global optimization of the network in the "connection + computing" architecture, so that the network can perceive computing and services, according to real-time resource status and user SLA (Service LevelAgreement, service level agreement) requirements, to achieve flexible scheduling of services, reasonable distribution of business, so as to provide users with a good experience.

See Figure 1. Figure 1 is a structural diagram of an edge network. The edge network includes a central node and multiple edge nodes. Multiple service modules can be deployed on each edge node at the same time, and the same service can be deployed on different edge nodes at the same time. Modules to provide users with different network services. For example, both edge node 1 and edge node 2 are deployed with VR service modules.

For example, based on CDN (Content Delivery Network, content distribution network) technology, a cache server (CDN cache server) may be deployed in a region or network where user access is relatively concentrated. When a user accesses a network service, the global load technology is used to direct the user's access to the nearest cache server, and the cache server responds to the user request.

Referring to FIG. 2 , FIG. 2 is a schematic diagram of processing a service request in the related art.

①. When the user clicks on the service option on the APP (Application, application, that is, the client), the client sends a request to the local DNS (Domain Name System, domain name resolution system) to send an IP address resolution request.

②. The local DNS forwards the IP (Internet Protocol, Internet Protocol) address resolution request to the CDN dedicated DNS server.

③. The CDN dedicated DNS server sends the IP address of the CDN load balancing device to the client.

④. The client sends a URL access request to the CDN load balancing device.

⑤. The CDN load balancing device selects a CDN cache server from the region to which the client belongs according to the IP address of the client and the URL requested by the user.

⑥. The CDN load balancing device sends the IP address of the CDN cache server to the client.

⑦. The client sends a resource request to the CDN cache server, and the CDN cache server sends a resource response to the client.

8. If the resource requested by the client does not exist in the CDN cache server, the CDN cache server requests the resource from the origin server of the service, and sends the requested resource to the client.

It can be seen that in related technologies, the application layer is decoupled from the network layer, that is, network services cannot perceive the network status of the network. For example, in step ⑤ of the above process, when the CDN load balancing device determines the CDN cache server, it does not consider the network status between the client and the CDN cache server, and thus fails to process the request in consideration of the network status , the processing performance of the network cannot be fully utilized, resulting in low service quality of the network service, and the service cannot meet the best user experience.

In order to solve the above problems, the present application provides a request processing method, which is applied to a management node in a request processing system. For example, referring to FIG. 3 , FIG. 3 is a structural diagram of a request processing system provided by an embodiment of the present application. The management node in this application may also be referred to as a centralized manager. In Fig. 3, the request processing system includes a centralized manager, multiple network nodes, and multiple computing power nodes; each computing power node communicates with a network node, and each computing power node is deployed with at least one network node The service module and the data transceiver module of the service. Wherein, the data transceiving module is used for receiving the service request sent by the client, and forwarding the service request to the corresponding service module, and receiving the service response sent by the service module, and forwarding the service response to the client. For example, service module 1-service module n is deployed in computing power node 1-1. Each service module can provide corresponding network services, such as VR services, V2X services, live video services, file storage services, and so on.

Correspondingly, refer to FIG. 4, which is an example diagram of a request processing method provided in an embodiment of the present application. The method may include the following steps:

S401: Receive a first service request sent by a user terminal.

Wherein, the first service request carries a service identifier representing the network service requested by the client.

S402: Determine a service module consistent with the service identifier from the service modules contained in each computing power node as a candidate service module.

S403: For each candidate service module, determine a network path between the computing power node to which the candidate service module belongs and the client as a candidate network path.

S404: Based on the network state information of each network node, according to the path search strategy corresponding to the type of network service represented by the service identifier, determine the target network path from each candidate network path, and determine the target network path from the computing power nodes corresponding to the target network path. A target service module is determined among the candidate service modules.

Wherein, the target service module is used to provide the network service requested by the client.

S405: Send the first service response carrying the network address of the target service module to the user end, and send forwarding information matching the target network path to each network node in the target network path, so that the user end can send to the network nodes in the target network path The network node sends the second service request carrying the network address of the target service module, and each network node in the target network path forwards the second service request according to the received forwarding information until the computing power of the target service module is deployed The node receives the second service request, and responds to the second service request through the target service module.

Based on the request processing method provided in the embodiment of the present application, since different types of network services have different requirements on the network, the target network path is determined based on the path search strategy corresponding to the type of network service and the network status information of each network node, and then , process the service request according to the target network path, which can meet the business requirements of the service request, that is, the service request can be processed in combination with the state of the network, and the processing performance of the network can be fully utilized to improve the service quality of the network service.

For steps S401 and S402, the network node in the request processing system may be a router in the network. A computing power node is a node used to provide network services. For example, a computing power node can be a physical server, or it can also be a cloud platform deployed with a virtual machine. The service module in the computing power node can be software that provides network services.

A service module that is consistent with the service identifier, that is, a service module that can provide corresponding network services. Since the request processing system includes multiple computing power nodes, and at least one service module is deployed in each computing power node, the service modules deployed in each computing power node may be the same or different. That is to say, in the request processing system, there may be multiple service modules that can provide the same network service.

The user terminal can send a service request carrying a corresponding service identifier to the management node according to the user's requirements. Furthermore, after receiving the service request, the management node can determine the network service requested by the user based on the service identifier, and correspondingly, can select a service module that can provide the network service, so as to respond to the user's service through the selected service module ask.

In an implementation manner, all service modules consistent with the service identifiers in the request processing system may be determined as candidate service modules.

In another implementation, in order to improve the service quality of network services, the first service request also carries the network address of the client; correspondingly, the above step S402 may include the following steps: determine from the service modules included in each computing power node The service module that is consistent with the service identifier and whose network address of the computing power node and the network address of the client belong to the same area is used as an alternative service module.

In this embodiment of the application, if the network address of the computing power node to which the service module belongs belongs to the same area as the network address of the client, it indicates that the physical distance between the computing power node to which the service module belongs and the client is relatively close. The service module responds to the service request of the client, and can improve the service quality of the network service. Therefore, a service module whose network address of the computing power node and the network address of the user end belong to the same area can be determined as a candidate service module.

For step S403, one candidate service module may correspond to one candidate network path, or may correspond to multiple candidate network paths, that is, the client may perform data communication with the same candidate service module through multiple different network paths.

It can be understood that the alternative network path includes at least one network node, and through the at least one network node, the service request sent by the client can be forwarded to the alternative service module in the corresponding computing power node.

For steps S404 and S405, the type of network service can be determined according to the requirements of the network service. For example, for V2X service, because it requires a small delay to ensure the safety of automatic driving, the type of V2X service can be delayed Time-demanding type, that is, for delay-demanding network services, it is necessary to reduce the response time of service requests. For the VR service, since it needs to transmit a large amount of data and occupies a large bandwidth resource, the type of the VR service can be bandwidth-demanding.

Since different types of network services have different requirements on the network, the target network path determined based on the path search strategy corresponding to the type of network service and the network state information of the network nodes can meet the business requirements of the service request.

It can be understood that the target network path includes at least one network node, and through the at least one network node, the service request sent by the client can be forwarded to the computing power node to which the target service module belongs (may be referred to as the target computing power node), also That is to say, the target computing power node communicates with the last network node in the target network path.

Since the forwarding information matches the target network path, the network node forwards the service request according to the forwarding information, and can also forward the service request according to the target network path, so that the service request can be transmitted from the user end to the target computer according to the target network path. The power node, and then the target computing power node can respond to the service request through the target service module.

If the target computing power node includes a candidate service module that provides the network service requested by the client, the candidate service module can be determined as the target service module.

If the target computing power node includes multiple candidate service modules that provide the network service requested by the client, one of the multiple candidate service modules may be selected as the target service module according to a preset selection strategy.

For example, target service modules can be selected based on load balancing policies. For example, the management node may determine the load of each candidate service module, and determine the candidate service module with the smallest load as the target service module. Alternatively, there is a designated order among the multiple candidate service modules, and correspondingly, the management node may determine the current candidate service module as the target service module according to the designated order.

For another example, the management node may randomly select a candidate service module as the target service module.

In addition, the management node may also send the network address of the first network node in the target network path to the user terminal. Further, the user end may send the second service request carrying the network address of the target service module to the first network node in the target network path. The first network node forwards the second service request to the second network node according to the forwarding information, and so on until the target computing power node receives the second service request.

In one embodiment, each computing power node may include a data transceiving module. Each computing power node can generate a corresponding network address for the deployed service module, for example, it can be a VIP (Virtual Internet Protocol, virtual Internet Protocol) address, and then, the computing power node can notify the network node connected by communication through the data transceiver module Its own node ID and the network address of the deployed service module. In addition, the data transceiving module can also forward the service request to the corresponding service module when receiving the service request, so that the service module can respond to the service request.

Correspondingly, each network node can notify the management node of the node ID of the computing power node and the network address of the service module deployed in the computing power node, and can notify other network nodes and management nodes of its own routing information.

In addition, each network node may also periodically send network status information to the management node.

For example, referring to FIG. 5 , FIG. 5 is a schematic diagram of a management node processing a service request provided by an embodiment of the present application. The management node can include collection module, decision-making module, execution module and service management module. The collection module can obtain the routing information uploaded by each network node, service information (including the identification of the computing power node, the network address of the service module deployed in the computing power node) and the network status information of the network node. Correspondingly, based on the above recorded information, the routing information for each service module can be determined, and the service information can be sent to the service management module, and the routing information and network status information can be sent to the decision-making module. The service management module can determine the service type corresponding to the service request, and then can determine the corresponding path search strategy and candidate service modules, and send them to the decision-making module. The decision-making module can determine the target network path from the candidate network paths corresponding to the candidate service modules according to the path search strategy, and determine a target service module from the candidate service modules contained in the computing power node corresponding to the target network path, and send to The execution module sends the target network path and the network address of the target service module; the execution module can send the network address of the target service module to the client, and send forwarding information matching the target network path to each network node in the target network path. Based on this, the management node can obtain the latest network state information, so that the determined target network path can effectively match the current network state, further improving the service quality of network services.

In one embodiment, the forwarding information of a network node in the target network path includes: the network address of the target service module, the corresponding relationship between the next hop in the target network path and the outgoing interface, and is used to indicate that the network node receives For the second service request carrying the network address of the target service module, the received second service request is forwarded to the next hop in the target network path through the corresponding outbound interface.

In the embodiment of this application, after obtaining the routing information of each network node and the network address of the service module deployed in each computing power node, the management node can determine the target network path according to the corresponding path search strategy, that is, it can determine From the user end to each network node between the target computing power node, and the order of each network node in the target network path can be determined.

Correspondingly, for each network node in the target network path, the management node can determine the next network node (that is, the corresponding next hop) of the network node, and can also determine the corresponding outbound interface of the next hop, and correspondingly , the management node can send the corresponding relationship of the network address, next hop, and outgoing interface of the target service module to the network node.

Furthermore, when receiving the second service request carrying the network address of the target service module, the network node can query the corresponding relationship, that is, forward the received second service request through the outgoing interface recorded in the corresponding relationship The next hop in the network path to the destination.

It can be understood that the last network node in the target network path may forward the second service request to the target computing power node. After the target computing power node resolves the network address of the target service module carried in the second service request, it can respond to the second service request through the target service module. In addition, the target computing power node may also send the second service request to the client through the target network path.

In one embodiment, the network service represented by the service identifier is a delay-demanding network service; the network state information includes the delay between network nodes; correspondingly, the above step S404 may include the following steps:

Step 1: For each candidate network path, based on the delay between network nodes in the candidate network path, calculate the distance between the client and the computing power node to which the corresponding candidate service module belongs in the candidate network path The delay between is used as the delay of the alternative network path.

Step 2: Determining the candidate network path with the minimum delay as the target network path.

Wherein, the delay between two network nodes may represent: the time required for network data to be transmitted from one network node to another network node.

In the embodiment of this application, for delay-demanding network services such as V2X services, since the delay required is small, that is, the response time of service requests needs to be reduced to ensure the safety of autonomous driving, therefore, when determining the service When the network service represented by the identification is a delay-demanding network service, the management node can obtain the delay between network nodes uploaded by each network node.

For example, for each candidate network path, the management node can obtain the delay between every two adjacent network nodes in the candidate network path, and then calculate the sum of each delay as the delay of the candidate network path hour.

Furthermore, the candidate network path with the smallest delay is determined as the target network path, so that the target service module can reduce the response time of the service request through the target network path, which can also meet the business requirements of delay-demanding network services and improve the quality of the network. Service quality of service.

In one embodiment, the network service represented by the type identifier is a bandwidth-demanding network service; the network status information includes bandwidth information of the interface of the network node; correspondingly, the above step S404 may include the following steps:

Step 1: For each candidate network path, calculate the available bandwidth of the candidate network path based on the bandwidth information of the interface of each network node in the candidate network path.

Step 2: Determine the candidate network path with the largest available bandwidth as the target network path.

The bandwidth information of the interface may include the maximum bandwidth of the interface and the currently used bandwidth of the interface, or may also include the bandwidth utilization of the interface, that is, the ratio of the currently used bandwidth of the interface to the maximum bandwidth.

In the embodiment of this application, for bandwidth-demanding network services such as VR services and live video broadcasts, since they need to transmit a large amount of data and occupy relatively large bandwidth resources, when determining the network service represented by the service identifier as bandwidth For demand-type network services, the management node can obtain the bandwidth information of the interface of the network node uploaded by each network node.

For example, for each candidate network path, the management node may acquire bandwidth utilization rates of interfaces of network nodes in the candidate network path, and then use the maximum value of each bandwidth utilization rate as the available bandwidth of the candidate network path.

Or, for each candidate network path, the management node can obtain the remaining bandwidth of the interface of each network node in the candidate network path (that is, the difference between the maximum bandwidth and the currently used bandwidth), and then use the The minimum value is used as the available bandwidth of the alternative network path.

Furthermore, the candidate network path with the largest available bandwidth is determined as the target network path, so that the bandwidth requirement of the service request can be met through the target network path, and the service quality of the network service is improved.

Based on the same inventive concept, the present application also provides a request processing system, which includes a management node, multiple network nodes, and multiple computing power nodes; each computing power node communicates with a network node, and each computing power At least one service module for providing network services is deployed in the node; where:
