AN IMPLEMENTING METHOD OF BINDING THE WORKING LABEL SWITCHED PATH WITH THE PROTECTION LABEL SWITCHED PATH

摘要

An implementing method of binding the working label switched path with the protection label switched path comprises the steps: the path switched label switching router (PSL) transmits the first message including the binding information to the path merging label switching router (PML), to demand setting up the protection LSP for the working label switched path (LSP); PML assigns the label for the protection LSP based on the first message, and returns the second message carrying the binding information; after PSL receiving the second message, PSL binds the working LSP with the protection LSP based on the binding information, and transmits the notification message carrying the binding information to PML; PML binds the working LSP with the protection LSP based on the binding information in the notification message.
