Detailed Description
The inventor notices in the process of invention that:
fig. 3 is a schematic diagram of a routing configuration, and as shown in the diagram, in the existing routing table configuration, the routing table is directly configured manually based on RMS, which is inefficient and inaccurate. If the route configuration is completed based on vGW (Virtual Gateway), all default route configuration data is forwarded by vGW, with a risk of congestion at vGW.
When a user sends a service request, the intelligent gateway reports a service message to an OSS (Operation-Support System) network management System through an RMS (root mean square) System, network management personnel generate a routing table through manual Operation and send the routing table to the intelligent gateway, and the gateway forwards the service message according to the routing table.
The routing table used by the current intelligent gateway for realizing routing forwarding is generated by network management personnel through manual operation, the workload is large, the accuracy of the routing table cannot be guaranteed, the risks of misoperation, failure in reaching the optimum and the like exist, and further, the priority of the service cannot be guaranteed.
Based on this, the embodiment of the present invention provides a gateway route configuration scheme, a route configuration policy is formulated through vGW, and the route configuration is forwarded to the gateway side based on interaction between the RMS and the controller, and the gateway directly communicates with the configured route according to the route table and bypasses vGW nodes. Therefore, the gateway new traffic only needs to pass through the vGW node once, reducing the possibility of vGW congestion while avoiding a decrease in manual configuration accuracy.
The following describes embodiments of the present invention with reference to the drawings.
In the process of description, the implementation of the intelligent gateway, vGW and the policy server will be described separately, and then an example of the implementation of the three will be given to better understand the implementation of the solution given in the embodiment of the present invention. The above explanation does not mean that the three must be implemented together or separately, and actually, when the intelligent gateway, vGW and policy server are implemented separately, they solve the problem on their own side, and when the three are used in combination, a better technical effect is obtained.
Fig. 4 is a schematic diagram of an implementation flow of a routing method on an intelligent gateway, as shown in the figure, including:
In implementation, the intelligent gateway forwards the service message according to the routing table, and sends the service message to the destination IP through the OLT.
Fig. 5 is a schematic flow chart of an implementation of the routing table processing method at vGW, as shown, including:
Fig. 6 is a schematic implementation flow diagram of a routing table processing method on a policy server, as shown in the figure, including:
In implementation, the routing table is generated by vGW and sent to the intelligent gateway after interacting with the controller based on RMS.
In an implementation, the intelligent gateway may further include:
the data is sent vGW in the default routing configuration to trigger vGW to generate a routing table.
Accordingly, at vGW, there is further included:
receiving data sent to vGW by the intelligent gateway according to the default route configuration;
and applying for service priority from the policy server.
In practice, after the policy server provides vGW with the traffic priority, vGW generates a routing table based on the traffic priority provided by the policy server.
The following is an example.
Fig. 7 is a schematic diagram of a routing process implemented, and as shown in the figure, in a network environment mainly composed of a gateway, an RMS, a controller, an OLT, a vGW, an orchestrator, a controller, a policy server, a destination IP, and the like, the following may be implemented:
1. the gateway sends vGW the data in a unified way according to the default route configuration.
2. vGW makes an application to the policy server.
3. The policy server parses the application, and the QoS priority.
4. The policy server feeds back vGW the priority.
5. vGW generate routing tables.
6. The controller receives a backup routing configuration.
7. The RMS interacts routing tables with the controller to the RMS.
8. The RMS issues the routing configuration to the gateway.
9. The gateway forwards the service message to the OLT, and the OLT directly sends the service message to the destination IP without passing through vGW.
Specifically, the routing table is usually configured manually based on RMS directly, which is inefficient and inaccurate. If route configuration is done based on vGW, all default route configuration data is forwarded by vGW, with a risk of congestion at vGW.
The scheme illustrated in fig. 7 includes elements of an existing network structure, as well as new nodes such as new policy servers, organizers, etc. The policy server authorizes vGW the priority; vGW generating a routing table and forwarding to the gateway through the management platform; after the gateway obtains the routing table, it is no longer sent to vGW through the default route, but directly bypasses vGW for transmission.
