Method and device for informing change of common route in networked devices

Abstract

The invention discloses a method and device for public route change notification in network equipment. The method includes: acquiring attribute information and route-related information of each characteristic module and a routing change processing scheme; according to the obtained attribute information of each characteristic module and Routing-related information establishes a feature module routing information linked list; checks the feature module routing information linked list according to a predetermined method, and processes the changed route through the routing change processing plan provided by the corresponding feature module; modifies the feature module route according to the change of the feature module route Information linked list. The device consists of public modules and at least one characteristic module. Utilizing the present invention, it is possible to simply and efficiently perform route change notification and processing, and at the same time realize route backup to ensure normal operation of the network system.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for public route change notification in network equipment. Background technique [0002] With the continuous expansion of computer network scale and the rapid development of large-scale Internet (such as the Internet), routing technology has gradually become a key part of network technology, and routers have also become the most important network equipment. Routers work at the third layer of the OSI (Open Systems Interconnection) model, the network layer. The router uses the "logical" network address (that is, IP address) defined by the network layer to distinguish different networks, realize the interconnection and isolation of the network, and maintain the independence of each network. [0003] In routers and high-level switch devices, the routing information learned through routing protocols is not only directly used by the IP (Internet Proto...

Problems solved by technology

[0008] In this mechanism, the routing change is no longer notified by the IP forwarding module, but is checked by each feature module itself. However, due to the lack of a unified mechanism, each module has a set of codes for similar functions, resulting in code The amount of maintenance is large, and the maintenance workload is correspondingly large, which does not conform to the principle of "reusable and modular" in code design
