METHOD FOR POSITIONING LSP WITH ERROR AND PCC AND PCE

摘要

Disclosed is a method for positioning a label switched path (LSP) with an error, and the method comprises: a path computation client (PCC) receiving at least one path computation element communication protocol error (PCErr) message; the PCErr message carrying at least one piece of identification information about a label switched path (LSP) with an error; and the PCC determining, according to the received PCErr message, the LSP with an error. Further disclosed are a PCC and a path computation element (PCE).
