Problems solved by technology

With the expansion of network scale and flat network design, users usually hope that the total number of neighbors and routing capacity supported by the link state routing protocol can be increased with the increase of hardware resources such as routing processors to realize link state routing. The expansion of the protocol, the traditional link state routing protocol operation mode cannot realize the expansion of the link state routing protocol because it is concentrated on a single routing processor

Embodiment Construction

[0024] The operation mode of the traditional link-state routing protocol is concentrated on a single routing processor, which is limited by the processing capability of the routing processor itself, and cannot realize the expansion of the link-state routing protocol. A routing processing method provided by the embodiment of the present invention, By dynamically distributing the functions contained in the link-state routing protocol to multiple routing processors, the scalability of the link-state routing protocol can be realized.

[0025] The router's multi-routing processor operating architecture generally consists of two parts: several nodes and the internal communication network between them. These nodes are usually organized into a distributed master-slave relationship, that is, a certain node is the master node, and other nodes are distributed slave nodes. Among them, each node includes: routing processor, used to run router control plane tasks such as routing protocols; ...

Abstract

The invention embodiment discloses a route processing method which includes that the connections among the nodes in the network are established; the nodes are processed with task scheduling; the nodes operate the link-state routing protocol, process route computation and obtain the route results according to the scheduled tasks; the route computation results of the nodes are acquired and the route summarization is processed. The invention embodiment also provides a route processor which includes a task scheduling module used for the task scheduling, a protocol operation module used for operating the link-state routing protocol according to the scheduled tasks, computing the routes and obtaining the route computation results and a route summarization module used for summarizing the route computation results. The invention embodiment also provides a router which has multi-route processor frame. The technical proposal provided by the route processing method can realize the extensibility of the link-state routing protocol.

Description

technical field [0001] The invention relates to computer network technology, in particular to a routing processing method of a link state routing protocol, a routing processor and a router. Background technique [0002] In the Internet, routers usually implement the forwarding of Internet packets. What guides routers in making forwarding decisions is the forwarding information base. This forwarding information base comes from routing information provided by different routing protocols. Routing protocols run by routers can be divided into border gateway protocols between autonomous systems and interior gateway protocols within autonomous systems according to application scenarios. Among them, an autonomous system refers to an Internet network in which management policies are implemented by a single management organization. Link-state routing protocols are currently the most widely used interior gateway protocols, mainly including Open Shortest Path First Protocol OSPF (Ope...
