Abstract

The present invention provides a method for switching label switching path update authority and related equipment. The method includes: receiving a PCUpd message, the PCUpd message carrying information to return the update authority of at least two LSPs created by the PCC; receiving path calculation Create a PCInitiate message for the label switched path; authorize the update authority of the at least two LSPs to the PCE sending the PCInitiate message according to the information carried in the PCInitiate message. In this way, the efficiency of switching the LSP update authority between PCEs can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for switching label switching path update authority and related equipment. Background technique [0002] Software Defined Network (Software Defined Network, referred to as SDN) is a new type of network architecture. Its design concept is to separate the control plane of the network from the data forwarding plane, so as to realize the programmability through the software platform in the centralized controller. It can realize the flexible and on-demand allocation of network resources by optimizing the control of the underlying hardware. [0003] In SDN, the Path Computation Client (PCC for short) can authorize the Label Switched Path (LSP for short) that it creates to update the attribute parameter capability to the Path Computation Element (PCE for short). , so that the PCE can update the LSP in time according to the change of the current network environme...
