Problems solved by technology

[0003] When the communication between the BFR (Bit Forwarding Router, bit forwarding router) nodes in the BIER network fails, the BIER message will not be forwarded normally, resulting in service interruption
However, in the prior art, no clear detection scheme has been proposed about how to detect communication failures between BFR nodes. Therefore, a method for detecting communication failures between BFR nodes is urgently needed

Abstract

The invention provides a BIER network fault detection method, device and equipment and a readable storage medium. The method comprises the following steps: establishing a bidirectional forwarding detection BFD session between a bit forwarding ingress router BFIR and a bit forwarding egress router BFER based on channel associated signaling; and when the BFIR or the BFER continuously receives the BFD control message for N times overtime, determining that the current service transmission path from the BFIR to the BFER has a fault, N being a positive integer greater than 1. According to the invention, the BFD session between the BFIR and the BFER is established, so that whether the current service transmission path from the BFIR to the BFER has a fault is determined based on whether the BFD session is normal, the service transmission path of the BIER network is rapidly detected, and the network robustness is enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a BIER network fault detection method, device, equipment and a readable storage medium. Background technique [0002] BIER (Bit Index Explicit Replication, Bit Index Explicit Replication) is a new type of multicast technology, which can greatly reduce the protocol complexity and intermediate state of the intermediate network, and it is easier to realize the transmission of multicast traffic in the intermediate network without intermediate The network records any multicast traffic status, which greatly simplifies network operation and maintenance. [0003] When the communication between the BFR (Bit Forwarding Router, bit forwarding router) nodes in the BIER network fails, the BIER message cannot be forwarded normally, resulting in service interruption. However, in the prior art, no clear detection scheme has been proposed regarding how to detect communication failures bet...
