Abstract
A method and system for implementing a pseudo wire control word capability negotiation are disclosed in the present document. The method includes: when modifying a local control word value, a Provider Edge (PE) acquiring a control word value configured or negotiated locally by an opposite terminal provider edge by sending label request message and receiving label mapping message, and according to the local control word value and the acquired control word value, the provider edge determining a control word value negotiated with respect to a pseudo wire. In the present document, the problem of inconsistency between the control word configurations and the expected negotiation results existing in certain specific scenarios is solved, which enhances the negotiation performance. The technical scheme of the present document makes slight modifications on the existing protocol, and it is applicable to a single segment pseudo wire scenario and a multiple segment pseudo wire scenario.
