Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.

With the wide application of AI (Artificial Intelligence) and 5G technologies, the rapid development of emerging services such as internet of things, large videos, internet of vehicles and the like is promoted, and the existing network architecture and cloud centralized deployment mode are difficult to meet the service requirements, so that the migration of networks and clouds along with the service flow direction edge by edge computing has become a new industrial trend.

In the related art, for a network angle, resources of a single edge station are limited, and a plurality of edge stations lack cooperation. Aiming at the service angle, the application layer is decoupled from the network layer, and the service cannot sense the network state. Therefore, in order to improve the quality of network Service, the network architecture needs to consider the network and the calculation fusion evolution cooperatively, so as to realize the global optimization of the network in the connection + calculation architecture, so that the network can sense the calculation and the Service, and realize the flexible scheduling of the Service and the reasonable distribution of the Service according to the real-time resource state and the user SLA (Service Level Agreement) requirements, thereby providing good experience for the user.

Referring to fig. 1, fig. 1 is a structural diagram of an edge network, where the edge network includes a central node and a plurality of edge nodes, each edge node may simultaneously deploy a plurality of service modules, and different edge nodes may simultaneously deploy the same service module, so as to provide different network services for users. For example, the edge node 1 and the edge node 2 are both provided with VR service modules.

For example, based on CDN (Content Delivery Network) technology, cache servers (CDN cache servers) may be deployed in regions or networks where user access is relatively centralized. When the user accesses the network service, the access of the user is directed to the cache server closest to the user by using the global load technology, and the cache server responds to the user request.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating a service request processing method in the related art.

(1) When a user clicks a service option on an APP (Application, i.e., user side), the user side sends an IP address resolution request to a local DNS (Domain Name System) according to a URL (Uniform Resource Locator) of a Resource requested by the user.

(2) And the local DNS forwards an IP (Internet Protocol) address resolution request to a DNS server special for the CDN.

(3) And the DNS server special for the CDN sends the IP address of the CDN load balancing equipment to the user side.

(4) And the user side sends a URL access request to the CDN load balancing equipment.

(5) And the CDN load balancing equipment selects a CDN cache server from the area to which the user side belongs according to the IP address of the user side and the URL of the user request.

(6) And the CDN load balancing equipment sends the IP address of the CDN cache server to the user side.

(7) And the user side sends a resource request to the CDN cache server, and the CDN cache server sends a resource response to the user side.

(8) And if the CDN cache server does not have the resources requested by the user terminal, the CDN cache server requests the resources from the source server of the service and sends the requested resources to the user terminal.

It can be seen that, in the related art, the application layer is decoupled from the network layer, that is, the network service cannot sense the network state of the network. For example, in step (5) in the above process, when determining the CDN cache server, the CDN load balancing device does not consider a network condition between the user side and the CDN cache server, that is, the request is not processed in combination with a state of the network, and processing performance of the network is not fully utilized, so that quality of service of the network service is not high, and the service cannot meet the best experience of the user.

In order to solve the above problem, 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 block diagram of a request processing system according to 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, a plurality of network nodes, and a plurality of compute power nodes; each computational power node is in communication connection with one network node, and at least one service module and a data transceiver module for providing network services are deployed in each computational power node. The data transceiver module is used for receiving a service request sent by a user side, forwarding the service request to a corresponding service module, receiving a service response sent by the service module, and forwarding the service response to the user side. For example, a service module 1-a service module n is deployed in the computing power node 1-1. Each service module is capable of providing a respective network service, e.g., VR service, V2X service, live video service, file storage service, etc.

Accordingly, referring to fig. 4, fig. 4 is an exemplary diagram of a request processing method provided in an embodiment of the present application, where the method may include the following steps:

s401: receiving a first service request sent by a user terminal.

The first service request carries a service identifier indicating a network service requested by the user terminal.

S402: and determining a service module consistent with the service identifier from the service modules contained in each computational force node as an alternative service module.

S403: and determining a network path between the computing node to which the alternative service module belongs and the user side as an alternative network path for each alternative service module.

S404: and determining a target network path from the alternative network paths based on the network state information of each network node and according to a path search strategy corresponding to the type of the network service represented by the service identifier, and determining a target service module from alternative service modules contained in the computational power node corresponding to the target network path.

The target service module is used for providing the network service requested by the user terminal.

S405: sending a first service response carrying the network address of the target service module to a user side, sending forwarding information matched with the target network path to each network node in the target network path, so that the user side sends a second service request carrying the network address of the target service module to the network nodes in the target network path, and forwarding the second service request by each network node in the target network path according to the received forwarding information until the computing node with the target service module receives the second service request, and responding to the second service request through the target service module.

Based on the request processing method provided by the embodiment of the application, because different types of network services have different requirements on the network, a target network path is determined based on the path search strategy corresponding to the type of the network service and the network state information of each network node, and then the service request is processed according to the target network path, so that the service requirement of the service request can be met, namely, the service request can be processed by combining the state of the network, the processing performance of the network can be fully utilized, and the service quality of the network service is improved.

For steps S401 and S402, the network node in the request processing system may be a router in the network. The computing node is a node for providing network services, for example, the computing node may be a physical server, or may also be a cloud platform with a virtual machine deployed therein. The service module in the computing node may be software that provides network services.

And a service module consistent with the service identification, that is, a service module capable of providing a corresponding network service. Because the request processing system comprises a plurality of computing power nodes, and each computing power node is provided with at least one service module, the service modules arranged in the computing power nodes can be the same or different. That is, in the request processing system, there may be a plurality of service modules capable of providing the same network service.

The user side can send a service request carrying the corresponding service identifier to the management node according to the requirement of the user. Further, after receiving the service request, the management node may determine, based on the service identifier, a network service requested by the user, and accordingly, may select a service module capable of providing the network service, so as to respond to the service request of the user through the selected service module.

In one implementation, all service modules in the request processing system that are consistent with the service identifier may be determined as alternative service modules.

In another implementation manner, in order to improve the service quality of the network service, the first service request also carries a network address of the user side; accordingly, the step S402 may include the following steps: and determining a service module which is consistent with the service identifier and belongs to the same area as the network address of the user side from the service modules contained in each computational force node to serve as an alternative service module.

In the embodiment of the present application, if the network address of the computing power node to which the service module belongs and the network address of the user side belong to the same area, it indicates that the computing power node to which the service module belongs is closer to the physical distance of the user side, and accordingly, if the service module responds to the service request of the user side, the service quality of the network service can be improved. Therefore, the service module, of which the network address of the computing node and the network address of the user side belong to the same area, can be determined as the alternative service module.

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

It is understood that the alternative network path includes at least one network node through which the service request sent by the user side can be forwarded to the alternative service module in the corresponding computational power node.

For step S404 and step S405, the type of the web service may be determined according to a requirement of the web service, for example, for the V2X service, since the requirement delay is small to ensure safety of automatic driving, the type of the V2X service may be a delay requirement type, that is, for the delay requirement type web service, a response time of the service request needs to be reduced. For the VR service, because the data amount required to be transmitted is large and occupies a large bandwidth resource, the type of the VR service may be a bandwidth-demand type.

Because 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 the network service and the network state information of the network node can meet the service requirement of the service request.

It is understood that the target network path includes at least one network node, through which the service request sent by the user side can be forwarded to the computing node to which the target service module belongs (which may be referred to as a target computing node), that is, the target computing node is communicatively connected to the last network node in the target network path.

Because the forwarding information is matched with 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 side to the target computing power node according to the target network path, and further, the target computing power node can respond to the service request through the target service module.

If the target computing force node comprises an alternative service module for providing the network service requested by the user side, the alternative service module can be determined as the target service module.

If the target computing power node comprises a plurality of alternative service modules for providing the network service requested by the user side, one of the alternative service modules can be selected as the target service module according to a preset selection strategy.

For example, a target service module may be selected based on a load balancing policy. 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. Or, a designated sequence is provided among the plurality of candidate service modules, and correspondingly, the management node may determine, according to the designated sequence, that the current candidate service module is the target service module.

For another example, the management node may randomly select an alternative 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 side. Furthermore, the user side may send a second service request carrying the network address of the target service module to the first network node in the target network path. And the first network node forwards the second service request to the second network node according to the forwarding information, and the like until the target force computing node receives the second service request.

In one embodiment, each computing node may comprise a data transceiver module. Each computing node may generate a corresponding network address for the deployed service module, for example, a VIP (Virtual Internet Protocol) address, and further, the computing node may notify the communicatively connected network node of its node identifier and the network address of the deployed service module through the data transceiver module. In addition, the data transceiver module may further forward the service request to the corresponding service module when receiving the service request, so that the service module responds to the service request.

Accordingly, each network node may advertise the node identifier of the computation force node and the network address of the service module deployed in the computation force node to the management node, and may advertise its own routing information to other network nodes and the management node.

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 logic diagram illustrating a management node processing a service request according to an embodiment of the present application. The management node may include an acquisition module, a decision module, an execution module, and a service management module. The acquisition module can acquire routing information, service information (including the identifier of the computational power node and the network address of the service module deployed in the computational power node) and network state information of the network nodes, which are uploaded by each network node. Accordingly, based on the recorded information, the routing information for each service module can be determined, and the service information is sent to the service management module, and the routing information and the network state information are sent to the decision module. The service management module can determine the service type corresponding to the service request, further determine the corresponding path search strategy and the alternative service module, and send the strategy and the alternative service module to the decision module. The decision module can determine a target network path from alternative network paths corresponding to the alternative service modules according to a path search strategy, determine a target service module from alternative service modules contained in a computational power node corresponding to the target network path, and send the target network path and a network address of the target service module to the execution module; the execution module can send the network address of the target service module to the user terminal and send forwarding information matched with the target network path to each network node in the target network path. Based on this, the management node can acquire the latest network state information, so that the determined target network path can be effectively matched with the current network state, and the service quality of the network service is further improved.

In one embodiment, the forwarding information for a network node in the target network path includes: and the network node is used for indicating that the network node forwards the received second service request to the next hop in the target network path through the corresponding outgoing interface when receiving the second service request carrying the network address of the target service module.

In the embodiment of the present application, after obtaining the routing information of each network node and the network address of the service module deployed in each computational power node, the management node may determine the target network path according to the corresponding path search policy, that is, may determine each network node from the user side to the target computational power node, and may determine the sequence of each network node in the target network path.

Correspondingly, for each network node in the target network path, the management node may determine a next network node of the network node (i.e., a corresponding next hop), that is, may determine an egress interface corresponding to the next hop, and correspondingly, the management node may send the network address of the target service module, the next hop, and a corresponding relationship between the egress interfaces to the network node.

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

It is to be appreciated that the last network node in the target network path may forward the second service request to the target computing force node. After the target computation force node resolves the network address of the target service module carried in the second service request, the target computation force node can respond to the second service request through the target service module. In addition, the target computing power node can also send the second service request to the user terminal through the target network path.

In one embodiment, the network service characterized by the service identifier is a network service of a delay demand type; the network state information includes delays between network nodes; accordingly, the step S404 may include the following steps:

the method comprises the following steps: and aiming at each alternative network path, calculating the delay between the user side in the alternative network path and the computational power node to which the corresponding alternative service module belongs based on the delay between the network nodes in the alternative network path, and taking the delay as the delay of the alternative network path.

Step two: and determining the alternative network path with the minimum delay as the target network path.

Wherein, the delay between two network nodes can be expressed as: the length of time required for network data to be transmitted from one network node to another.

In the embodiment of the present application, for network services requiring delay such as V2X services, since the required delay is small, that is, the response duration of the service request needs to be reduced to ensure the safety of automatic driving, when the network service represented by the service identifier is determined to be the network service requiring delay, the management node may obtain the delay between network nodes uploaded by each network node.

For example, for each alternative network path, the management node may obtain the delay between each two adjacent network nodes in the alternative network path, and then calculate a sum of the delays as the delay of the alternative network path.

Furthermore, the candidate network path with the minimum delay is determined as the target network path, so that the time for the target service module to respond to the service request can be reduced through the target network path, the service requirement of the delay-demand network service can be met, and the service quality of the network service is improved.

In one embodiment, the network service characterized by the type identifier is a bandwidth-demanding network service; the network state information includes bandwidth information of an interface of the network node; accordingly, the step S404 may include the following steps:

step 1: and calculating the available bandwidth of each alternative network path according to the bandwidth information of the interface of each network node in the alternative network path.

Step 2: and determining the alternative network path with the maximum available bandwidth as the target network path.

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

In the embodiment of the application, for bandwidth-demanding network services such as VR services and live video broadcasts, because the data volume to be transmitted is large and a large bandwidth resource is occupied, when it is determined that the network service represented by the service identifier is the bandwidth-demanding network service, the management node may obtain the bandwidth information of the interface of the network node uploaded by each network node.

For example, for each alternative network path, the management node may obtain bandwidth utilization rates of interfaces of network nodes in the alternative network path, and then take a maximum value of the bandwidth utilization rates as an available bandwidth of the alternative network path.

Alternatively, for each alternative network path, the management node may obtain the remaining bandwidths (i.e., the difference between the maximum bandwidth and the currently used bandwidth) of the interfaces of the network nodes in the alternative network path, and then use the minimum value of the remaining bandwidths as the available bandwidth of the alternative network path.

And then, determining the alternative network path with the largest available bandwidth 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.
