Abstract
A method for establishment a pseudo wire (PW) is disclosed, including: receiving a first label mapping (LM) message, where the first LM message carries a PW ID, PW parameters, and label switching path (LSP) tunnel information that are selected by the sender of the first LM message; matching a local PW according to the PW ID; performing parameter negotiation of the local PW according to the PW parameters; matching a local tunnel according to the LSP tunnel information; binding the local tunnel and the local PW when the matching between the PW ID and the LSP tunnel information is successful; and establishing a PW when the parameter negotiation is successful. A device and system for establishing a PW are also disclosed. With the present invention, a PW service is associated with an LSP tunnel to improve the reliability of the information transmission process.
