Detailed Description

Based on the embodiments of the present application, all other embodiments obtained by the person skilled in the art based on the present application are included in the scope of protection of the present application.
In view of the increasing diversity of industry applications, the network traffic original forwarding technology will gradually evolve into network traffic policy scheduling and adjustment based on application type base analysis. Therefore, it is important to realize a system based on application type flow analysis and management control, and a related system of a service application identification system aims at solving the problems that the existing SRv6 (Segment Routing IPv, segment routing based on an IPv6 forwarding plane) network layer flow cannot identify an application type and is adjusted and scheduled in real time, shortening the adjustment and scheduling time of the network layer application flow, and avoiding the need of distinguishing SRv6 network layer flow application types by various technical modes at a user side, and automatically executing SRv6 network application flow adjustment by the service application identification system, thereby improving service guarantee efficiency, reducing labor and physical hardware cost and greatly improving customer perception.
Referring to fig. 1, fig. 1 is a flow chart of a first flow forwarding method according to an embodiment of the present invention, where the method includes the following steps S101 to S104.
First, before explaining the above steps, an execution body of an embodiment of the present invention will be explained.
The implementation main body of the embodiment of the invention is network equipment, specifically, the network equipment is equipment accessed to each terminal equipment, after the terminal equipment sends network traffic, the first arrived equipment is the network equipment, and the network equipment determines a forwarding path of the network traffic. The network device may be a router, a gateway device, or the like.
Steps S101 to S106 will be specifically described below.
Step S101: and receiving the target network flow to be forwarded, which is sent by the terminal equipment, and determining target flow parameter information of the target network flow.
The target network traffic may be SRv6 network traffic.
The target flow parameter information is: traffic parameter information for the target network traffic. The target flow parameter information may include a parameter value of a preset network flow parameter item, where the network flow parameter item may include information such as a transmission rate and an occupied bandwidth of the network flow.
When determining the target flow parameter information, a preset information detection mode can be adopted to detect the flow parameter information of the target network flow, and the preset information detection mode can be any detection mode of the flow parameter information in the prior art.
Step S102: and determining the target service type of the service to which the target network flow belongs based on the target flow parameter information.
The target service type refers to: the service type of the service to which the target network traffic belongs. For example: when the service node provides the game service for the user, the service to which the network traffic transmitted in the network belongs may be the game service, where the service type of the service to which the network traffic belongs is: game service type.
The service types of the service to which the target network traffic belongs may include: browser service type, email service type, game service type, video service type, audio service type, etc.
In the case that the number of services subscribed to by the terminal device is large, the service types of the services to which the network traffic transmitted in the network belongs may be different, so that the network device needs to determine the target service type of the service to which the network traffic belongs. And because the difference between the flow parameter information of the network flows corresponding to the services of different service types is large, the service type of the service to which the target network flow belongs can be determined based on the flow parameter information of the target network flow.
In one embodiment, the target traffic parameter information of the target network traffic may be input into a pre-trained service type identification model to obtain a service type output by the service type identification model, which is used as a target service type of the service to which the target network traffic belongs.
The service type identification model is a model for carrying out service type identification on the flow parameter information.
When the service type identification model is trained, sample flow parameter information can be used as a training sample, and the actual service type of the service to which the sample network flow belongs is used as a training reference to train a preset neural network model.
Other embodiments for determining the target service type may refer to the following examples corresponding to fig. 2, and will not be described in detail herein.
Because the target service type is determined based on the target flow parameter information, the data packet in the target network flow is not required to be analyzed to obtain the target service type, and the problem of data packet safety caused by analyzing the data packet is avoided.
In addition, because the information recorded by the data packet in the target network flow is related to the service content, the data packet does not record the information related to the target network flow, so the data packet does not contain the parameter information of the target network flow, and in this case, the data packet in the target network flow does not need to be analyzed to obtain the parameter information of the target network flow, thereby further improving the safety of the data packet.
Step S103: a target forwarding path for forwarding the target network traffic is determined based on the target traffic type.
In one embodiment, a forwarding path corresponding to a target service type may be determined based on a preset correspondence between the service type and the forwarding path, and the forwarding path may be used as a target forwarding path for forwarding the target network traffic.
The correspondence between traffic types and forwarding paths may be predetermined. When the service type T and the forwarding path R have a corresponding relationship, the forwarding path of the network traffic included in the service of the service type T is the forwarding path R.
The forwarding path includes device information of network devices through which the target network traffic passes, and an order of the network devices through which the target network traffic passes. The device information may include identification of network devices, IP (Internet Protocol ) addresses, ports, etc.
The process of determining the target forwarding path is described below in conjunction with table 1. Table 1 shows the correspondence between the type of service and the forwarding path.
TABLE 1
| Service type | Forwarding path |
| Game service type | E1→E2→E3→D |
| Video service type | E2→E3→E4→D |
| Audio service type | E3→E4→E5→D |
The forwarding paths E1, E2, E3, E4, E5, and D in table 1 are all network devices.
When the target service type is the game service type, in table 1, the forwarding path corresponding to the game service type is: e1→e2→e3→d, so the target forwarding path is: E1→E2→E3→D.
Because the corresponding relation between the service type and the forwarding path is preset, based on the corresponding relation, the forwarding path corresponding to the more accurate target service type can be determined, so that the accuracy of the determined target forwarding path for forwarding the target network traffic is higher.
Step S104: and sending a policy generation request containing the target traffic parameter information and the target service type to the management equipment.
Specifically, after receiving the policy generation request, the management device may parse the policy generation request to obtain the target traffic parameter information and the target service type.
Step S105: and the receiving management equipment responds to the traffic forwarding strategy sent by the strategy generation request.
The traffic forwarding policy is as follows: a forwarding policy for forwarding the target network traffic. Specifically, the information such as the bandwidth required by forwarding the target network traffic, the required time delay and the like can be recorded in the traffic forwarding strategy.
Step S106: and forwarding the target network traffic by adopting a traffic forwarding strategy according to the target forwarding path.
In one embodiment, the information recorded in the traffic forwarding policy may be used to forward the target network traffic. For example: the bandwidth required for recording and forwarding the target network traffic in the traffic forwarding strategy is 10M, the required time delay is 10s, the network equipment can adopt the 10M bandwidth, and the target network traffic is reserved for 10 s.
As can be seen from the above, when the solution provided by the present embodiment is applied to forwarding traffic, because the network device determines the target forwarding path for forwarding the target network traffic according to the target service type, and obtains the traffic forwarding policy, and further forwards the target network traffic based on the determined target forwarding path and the traffic forwarding policy, compared with the prior art that the forwarding path is manually determined by relying on a worker, the efficiency of forwarding path determination is improved, and further the efficiency of traffic forwarding is improved.
And the target service type is determined based on the target flow parameter information, and the data packet in the target network flow is not required to be analyzed to obtain the service type corresponding to the target network flow, so that the problem of data packet safety caused by analyzing the data packet is avoided, the safety of the data packet is improved, and meanwhile, the efficiency of determining the service type is also improved.
In addition, the traffic forwarding policy is a policy generated based on the target parameter information and the target service type, where the target parameter information and the target service type are both information related to the target network traffic to be forwarded, and the traffic forwarding policy can be better applicable to the target network traffic, so that when the network device forwards the target network traffic by adopting the traffic forwarding policy, unnecessary consumption of network resources can be avoided, and network resources are saved.
In the implementation manner of step S103 in the foregoing embodiment shown in fig. 1, the correspondence between the preset service type and the forwarding path may be generated by a management device, where the management device is: an electronic device for managing network devices. Specifically, the management device may obtain service type parameter information of a service type of the service subscribed by the terminal device, calculate, based on the service type parameter information, a forwarding path by using a preset optimal path algorithm, and obtain a correspondence between a service type and the forwarding path as a forwarding path for forwarding network traffic included in the service.
After determining the forwarding paths for forwarding the network traffic included in the service, the management device may display the forwarding paths in a user interface provided by the management device, so that a worker may review the forwarding paths based on experience, and after the review, the management device sends a correspondence between the service type and the forwarding paths to each network device included in the forwarding paths, so that the network device may determine the forwarding paths for forwarding the network traffic based on the correspondence.
In order to adapt the forwarding paths corresponding to the service types to the network traffic in dynamic change, the forwarding paths corresponding to the service types can be updated periodically, so that updated corresponding relations are obtained, and then more accurate forwarding paths can be determined and obtained based on the corresponding relations.
Based on the analysis, in one embodiment of the present invention, after the step S106, the target service type and the target parameter information may be further sent to the management device; and receiving the adjusted target forwarding path sent by the management equipment, and updating the corresponding relation between the preset target service type and the target forwarding path based on the adjusted target forwarding path.
After receiving the target service type and the target parameter information, the management device can adjust a target forwarding path corresponding to the target service type based on the received information.
In one embodiment, the network device may periodically send the received traffic parameter information of the network traffic to be forwarded and the corresponding traffic type to the management device.
After receiving the adjusted target forwarding path, the network device replaces the original target forwarding path with the adjusted target forwarding path in the corresponding relation between the preset target service type and the target forwarding path, thereby realizing updating the corresponding relation.
In this way, when the forwarding path is determined by adopting the preset corresponding relationship later, the accuracy of the corresponding relationship between the service type and the forwarding path is higher due to the fact that the preset corresponding relationship is the updated corresponding relationship, so that the accuracy of the forwarding path determined later is also higher.
In step S102 of the embodiment shown in fig. 1, in addition to determining the target service type by using the service type identification model, the implementation of determining the target service type mentioned in the embodiment shown in fig. 2 may also be used. In an embodiment of the present invention, referring to fig. 2, fig. 2 is a schematic flow chart of a second flow forwarding method provided in this embodiment, and step S102 of the foregoing embodiment shown in fig. 1 may be implemented according to steps S202-S203 of the embodiment shown in fig. 2 described below.
Specifically, the embodiment shown in FIG. 2 includes the following steps S201-S207.
Step S201: and receiving the target network flow to be forwarded, which is sent by the terminal equipment, and determining target flow parameter information of the target network flow.
The step S201 is the same as the step S101 shown in fig. 1, and will not be described in detail here.
Step S202: and calculating the matching degree between the target flow parameter information and the flow parameter information corresponding to the stored service type.
The traffic parameter information corresponding to the service type is used for reflecting the parameter information of the network traffic included in the service of the corresponding service type. The flow parameter information may include a parameter value of a preset flow parameter item, where the preset flow parameter item may include a flow transmission rate, a bandwidth occupied by a flow, and the like.
Specifically, for each service type, the network device may perform statistical analysis on historical parameter information of network traffic included in the service of the service type, determine a statistical analysis result as traffic parameter information corresponding to the service type, and store the statistical analysis result. The statistical analysis method may be a method of calculating an average value, a calculation, a value, or the like.
In order to adapt to the dynamic change characteristic of the network traffic, the stored traffic parameter information corresponding to the service type is not fixed, but is updated and adjusted regularly. In one embodiment of the invention, the stored flow parameter information corresponding to the target service type can be updated based on the target flow parameter information.
In one embodiment, the statistical analysis may be performed again on the target flow parameter information and the history parameter information, and the statistical analysis result may be determined as updated flow parameter information and stored. In this way, when the traffic type is determined by adopting the stored traffic parameter information corresponding to the traffic type later, the accuracy of the traffic parameter information reflecting the parameter information of the target network traffic is higher because the stored traffic parameter information corresponding to the traffic type is updated information, so that the accuracy of the traffic type determined later is also higher.
In one embodiment, when calculating the matching degree, a difference value between a parameter value included in the target traffic parameter information and a parameter value included in the traffic parameter information corresponding to the traffic type may be calculated for each traffic type, and the matching degree may be determined based on the calculated difference value corresponding to each traffic type.
When the difference value is larger, the target flow parameter information is not matched with the flow parameter information corresponding to the service type, and the matching degree is smaller; and when the difference value is smaller, the target flow parameter information is matched with the flow parameter information corresponding to the service type, and the matching degree is larger.
Specifically, when calculating the difference value, an absolute difference between a parameter value of the preset flow parameter item in the target flow parameter information and a parameter value of the preset flow parameter item in the flow parameter information may be calculated for the same preset flow parameter item, and the absolute difference of each calculated preset flow parameter item is determined as a difference value between the target flow parameter information and flow parameter information corresponding to the service type.
Step S203: and determining the service type corresponding to the highest matching degree as the target service type of the service to which the target network flow belongs.
The process of determining the target traffic type is described below in connection with table 2. Table 2 shows the calculated matching degree and the service type corresponding to the matching degree.
TABLE 2
| Service type | Degree of matching |
| Game service type | 20％ |
| Video service type | 90％ |
| Audio service type | 60％ |
As can be seen from the above table 2, 90% is the highest matching degree, and the service type corresponding to 90% is the video service type, so that the target service type video service type of the service to which the target network traffic belongs can be determined.
Step S204: a target forwarding path for forwarding the target network traffic is determined based on the target traffic type.
Step S205: and sending a policy generation request containing the target traffic parameter information and the target service type to the management equipment.
Step S206: and the receiving management equipment responds to the traffic forwarding strategy sent by the strategy generation request.
Step S207: and forwarding the target network traffic by adopting a traffic forwarding strategy according to the target forwarding path.
Specifically, the steps S204-S207 are the same as the steps S103-S106 in the embodiment shown in FIG. 1, respectively, and are not described in detail herein.
From the above, the above-mentioned target service type is determined based on the service type corresponding to the highest matching degree, where the possibility that the service type of the highest matching degree is the service type of the service to which the target network traffic belongs is highest, so that the accuracy of determining the service type corresponding to the highest matching degree as the target service type is higher.
Referring to fig. 3, fig. 3 is a flowchart of a policy determining method according to an embodiment of the present invention, where the method includes the following steps S301 to S303.
First, before explaining the above steps, an execution body of an embodiment of the present invention will be explained.
The execution main body of the embodiment of the invention is a management device, and the management device is as follows: the electronic device for managing each network device may be an electronic device in a management platform, or the like.
Steps S301 to S303 are explained below.
Step S301: and receiving a policy generation request which is sent by the network equipment and contains the target flow parameter information and the target service type.
The target flow parameter information is: and the network equipment receives flow parameter information of the target network flow to be forwarded. The target service types are as follows: the service type of the service to which the target network traffic belongs.
In one embodiment of the present invention, the target service type may be one of the following service types: browser service type, email service type, game service type, video service type, audio service type.
The policy generation request is used for requesting to generate a traffic forwarding policy.
After receiving the policy generation request, the management device may parse the policy generation request to obtain the target traffic parameter information and the target service type.
Step S302: and obtaining target service parameter information of the target service type from the stored service parameter information of each service type.
The service parameter information of each service type may be stored in a preset database, and the management device may read the target service parameter information of the target service type from the database.
Step S303: and determining a flow forwarding strategy for forwarding the target network flow based on the target flow parameter information and the target service parameter information, and sending the flow forwarding strategy to the network equipment.
In one embodiment, the forwarding policy corresponding to the target traffic parameter information and the target service parameter information may be determined based on a corresponding relationship between preset parameter information and the forwarding policy, and the determined forwarding policy is used as a traffic forwarding policy for forwarding the target network traffic.
The parameter information in the corresponding relation comprises flow parameter information of network flow and service type service parameter information.
After obtaining the traffic forwarding policy, a response including the traffic forwarding policy may be generated, and the response may be sent to the network device, so that the network device obtains the traffic forwarding policy.
Therefore, the generated flow forwarding strategy is more applicable to the target network flow to be forwarded, and unnecessary consumption of network resources can be avoided and network resources can be saved when the subsequent network equipment forwards the target network flow based on the flow forwarding strategy.
And the flow forwarding strategy is generated based on the management equipment, so that compared with the flow forwarding strategy determined based on the experience of staff in the prior art, the efficiency of strategy determination is improved, and the labor cost is reduced.
The service parameter information mentioned for each service type in the above-described step S302 is predetermined, and specifically the above-described service parameter information may be generated in the following manner.
And generating service parameter information of each service type based on the service description information of each service type, the configuration information of each network device and the parameter information of the network resource.
In one embodiment of the present invention, the service description information of the service type may include: identification of service type, importance of service type, SLA of service type (Service Level Agreement ).
The network resources may include: computing resources, transmission resources, etc.
In one embodiment, the service description information, the configuration information of the network device, and the parameter information of the network resource may be integrated, and the integrated information is determined as the service parameter information.
Because the network traffic included in the service needs to be forwarded by the network equipment and the network resources, the service parameter information has an association relationship with the network equipment and the network resources. Thus, based on the service description information. The accuracy of the generated service parameter information is higher.
The following describes the flow forwarding method provided by the embodiment of the present invention in full with reference to fig. 4. Fig. 4 is a schematic structural diagram of a traffic forwarding system according to an embodiment of the present invention.
The traffic forwarding system comprises a service ordering unit, a service management unit, a service application identification unit, a network controller, an application characteristic acquisition unit and network equipment.
Specifically, a user subscribes a required service type through a service subscription unit, and the service subscription unit sends the service type subscribed by the user to a service management unit;
The service management unit generates service parameter information of the service type according to the service type, the description information of the service type, the configuration information of the network equipment and the parameter information of the network resource, and sends the service parameter information to the network controller.
And the network controller calculates an optimal forwarding path based on SRv after receiving the service parameter information to obtain a forwarding path for forwarding the network traffic corresponding to each service type, and displays the forwarding path on a user interface provided by the network controller for a worker to review, and after the worker passes the review, the network controller sends the corresponding relation between the service type and the forwarding path to each network device included in the forwarding path.
After receiving SRv network traffic to be forwarded, the network device determines SRv traffic parameter information of the network traffic, and determines a service type of the service to which the SRv network traffic belongs based on the traffic parameter information, so as to determine a forwarding path corresponding to the service type based on a stored corresponding relation, and the network device sends the traffic parameter information and the service type to an application feature acquisition unit;
