Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications, and especially relates to a method and a device for removing a residual label switching path (LSP), so as to resolve the problems of wrongly removing a normal resource or not being able to effectively remove a residual resource due to residual link erroneous determination. Said method is: a first node receiving a residual LSP removing request corresponding to a current LSP; when the first node determines, according to the path information of all LSPs stored by itself and the residual LSP removing request, an LSP belonging to the same group as the current LSP exists, forming a first LSP group of all LSPs belonging to the same group as the current LSP; the first node setting an LSP, among the first LSP group, not indicated by the residual LSP removing request as a second LSP group, and setting the LSP in the second LSP group as a residual LSP; the first node removing the LSP in the second LSP group. This can achieve the efficiency of the residual removing, and improving the reliability of the residual removing and the survivability of the services in the network.
