AI Technical Summary

Problems solved by technology

When large-scale BFD sessions are established in batches, the CPU is under sudden pressure. Often, the peer session detection times out and the BFD session flaps because the CPU does not send packets in time.

Abstract

The invention discloses a BFD session processing method, device, storage medium and routing equipment, which are applied to a first routing equipment. The method includes: when establishing communication with a second routing equipment using bidirectional forwarding to detect a BFD session, detecting the pre-configured own BFD session parameters and the BFD session parameters of the second routing device; generate a packet sending interval and a detection timeout time according to the BFD session parameters; and determine the packet sending interval and / or during the BFD session parameter negotiation process with the second routing device Whether the detection timeout supports hardware maintenance; when the packet sending interval and / or the detection timeout support hardware maintenance, the hardware maintenance is used to maintain the packet sending interval and / or the detection timeout time; when the packet sending interval or the detection timeout time does not support hardware maintenance, Then use the software to maintain the packet sending interval or detect the timeout time. Therefore, by adopting the embodiment of the present application, the probability of peer session detection timeout and session flapping is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a BFD session processing method, device, storage medium and routing equipment. Background technique [0002] BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) is a general, standardized, media-independent and protocol-independent fast fault detection mechanism, which is used to detect the connectivity status of the forwarding path. Usually, routing protocols, such as OSPF / IS-IS / BGP, use the Hello message mechanism to detect faults, and the required time is seconds. BFD can provide them with millisecond-level detection, quickly detect communication failures, and switch to backup links to ensure continuous business operation. [0003] With the development of high-performance single routers and multi-clusters, the number of links supported by the entire system is increasing, and more BFD sessions are required to quickly detect link fa...
