Abstract

The invention provides a method and device for selecting a backup LSP, belonging to the field of network communication. In order to make full use of network resources, the present invention provides a method for selecting a backup LSP, including: calculating backup LSPs of all primary LSPs in the network, and determining the backup LSP as the current backup LSP when the backup LSP is better than the original backup LSP backup LSP, otherwise the original backup LSP is the current backup LSP. The present invention also provides a device for selecting a backup LSP, which includes a calculation module, a comparison module and a current backup LSP determination module. The scheme of the invention minimizes the bandwidth reserved by the network for the recovery path, thereby improving the utilization rate of the network bandwidth.

Description

technical field

[0001] The present invention relates to the field of network communication, in particular to a method and device for selecting a backup LSP (Label Information Base, label switching path). Background technique

[0002] The MultiProtocol Label Switching (MPLS, MultiProtocol Label Switching) technology is produced according to the requirements of the network itself. Various network communication services have higher and higher requirements on the performance of the network. At the same time, the network is required to be able to transmit voice, image and other data, with fast transmission speed, less delay, and better quality of service (QoS, Quality of Service) and other performance. MPLS is a label switching technology between the second layer and the third layer. It is specially designed for IP. It combines the high-speed switching capability of the second layer with the flexible characteristics of the third layer, so that the IP network has High-speed swit...
