[0044] In the first embodiment of the present invention, a method for implementing routing update, such as Figure 6 As shown, perform the following steps in the switching access device and / or switching network element:

[0045] In step S101, a routing aging table is established according to the received routing information.

[0046] Specifically, because both the switching access device or the switching network element are in the network, when establishing a route, the switching access device itself can have two functional roles as a source switching access device and a destination switching access device. The ingress device can receive the routing information sent by the corresponding destination switching access device through all available links. In addition, according to the basic functions of the switching network element, a switching network element can also receive the routing information sent by the corresponding switching access device through all its available link...

Abstract

The invention discloses a method and device for implementing routing update. The method is executed in a switching device: step 1, establish a routing aging table according to the received routing information; The routing table is synchronized consistently; step 3, after the synchronization is completed, clear the routing aging table, and repeat step 1. The invention performs updating through route aging, which can ensure the stability and reliability of the switching system. The device is located in the switching equipment and includes: a route establishment module, a route update module and a route aging module. Compared with the prior art, the present invention ensures the stability and reliability in the data exchange process. Although the routing aging function will increase additional system resource overhead, the consumed system resources only occupy a small part, which can be ignored. of.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method and device for implementing routing update. Background technique [0002] The switching system is used to complete high-speed and high-capacity information exchange of network packets. The switching system consists of switching access devices and switching networks, which are connected by links. Such as figure 1 As shown, the switching access device is divided into two functional roles: the source switching access device 101 and the destination switching access device 102 , and the switching network is composed of switching network elements 103 . The switching access device 101 at the source end receives network packets and cuts them into cells. Cells are a specific transmission form of the switching system and are transmitted to the switching network. The switching network completes the transfer and duplication of cells. The destination switching acce...
