Link failure processing method and data forwarding device

Abstract

The embodiment of the invention provides a link failure processing method and a data transmitting device, wherein the method comprises detecting that a link goes wrong, starting a timer, sending out failure detecting conversation dropping notice, receiving a detecting message by the timer before time over, keeping the neighbor relationship with a neighbor route device connected through a link, generating route information, and sending out the route information. The invention simultaneously provides a data transmitting device for implementing the method. The embodiment of the invention can shorten the convergence time length of an upper-layer application module, improves the convergence property, and saves CPU resource of the data transmitting device, and improves the working property thereof.

Description

technical field

[0001] The invention relates to communication technology, in particular to a link failure processing method and a data forwarding device. Background technique

[0002] With the rapid popularization of the network and the continuous enrichment of network applications, the traffic on the network continues to expand, the scale of the network is also increasing, and the network devices in it are becoming more and more difficult to maintain and manage. For this reason, an increasingly important feature that network equipment is required to have is: network equipment is required to have a fault detection function, so that when the path between adjacent network equipment fails during the communication process, the network equipment can detect the failure. Perform rapid detection, quickly establish a new communication channel to replace the faulty communication channel, or switch the communication from the faulty communication channel to other links. Some existing n...
