The method includes: a second equipment receives a negotiation message from a first equipment, where the message carries the BFD capability of VCCV of the PW at the first equipment and the BFD discriminator; and then sends to the first equipment a message which carries the BFD capability of the VCCV of the PW at the second equipment and the BFD discriminator allocated to the PW after obtaining the BFD capability and BFD discriminator from the first equipment if the local PW supports the BFD capability; or, sends to the first equipment a message which carries information indicating that the local PW does not support the BFD capability if the local PW does not support the BFD capability. Through this method, the process of negotiating the BFD session discriminator is simplified."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for negotiating the bidirectional forwarding detection session discriminator of pseudo wire","description":"A method, apparatus and system for negotiating the BFD session discriminator of the PW are disclosed.
