Problems solved by technology

[0004] However, if there is a certain data transmission bit error rate in the traffic received by the tail node and the intermediate nodes, and the data transmission bit error rate detected by the tail node and the data transmission bit error rate detected by each intermediate node do not reach the error rate However, in the actual transmission process, the bit errors generated by each intermediate node receiving the service flow have affected the reliability of the service flow transmission

Abstract

Embodiments of the present application provide a method and apparatus for tunnel switching, which relate to the field of communication technology and are used to solve the problem of low service reliability caused by the prior tunnel switching method. The method comprises the steps of receiving a first total bit error rate transmitted by an adjacent third node by a first node, wherein the first total bit error rate is the sum of the data transmission bit error rate of the traffic stream received by the second node and the data transmission bit error rate of the same traffic stream received byat least one third node. Then, if the first total bit error rate reaches a preset threshold, the first node switches the traffic stream carried by the first TE tunnel to the second TE tunnel.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a tunnel switching method and device. Background technique [0002] Multiprotocol Label Switching (Multiprotocol Label Switching, MPLS) Traffic Engineering (Traffic Engineering, TE) is a scalable and easy-to-implement traffic engineering solution, which combines MPLS technology and traffic engineering, and can be established along a specified path Resource reservation is performed on a label switched path (Label Switched Path, LSP) tunnel. [0003] At present, the switching between the active and standby tunnels of MPLS TE can be realized through bit error detection. When the bit error rate reaches the threshold of bit error switching, the node will trigger the switching of the active and standby tunnels, that is, switch the service flow carried by the main tunnel to the backup tunnel. [0004] However, if there is a certain data transmission bit error rate...
