Abstract:
1. A method for allocating a label in a seamless multi-protocol label switching network based on pseudowire (PW) emulation edge-to-edge, the PW is an end-to-end single segment PW between the first access node and a second access node, comprising: obtaining, by a first router, label information of a first access node, wherein the label information comprises a PW destination address of the first access node and a single segment PW label of the end-to-end single segment PW between the first access node and the second access node, wherein the PW destination address of the first access node is thean address of the second access node; sending, by the first router, the label information, which includes the single segment PW label, to a second router by using a Border Gateway Protocol (BGP) message or a Target-Label Distribution Protocol (T-LDP) message; obtaining, by the second router, the single segment PW label carried by the BGP message or the T-LDP message; sending, by the second router, to the second access node, the obtained single segment PW label carried by the BGP message or the T-LDP message to the second access node by using a first access network configuration protocol, wherein the first access network configuration protocol is any one of Optical Network Terminal Management and Control Interface (OMCI) Protocol, Access Node Control Protocol (ANCP) Protocol, Ethernet Operations, Administration and Maintenance (Ethernet OAM) Protocol and TR069 protocol.
