摘要： A method and apparatus for providing information in a network by way of a Pseudowire switching TLV is presented. A second device in the network receives a first message having information relating to a first device in the network. The second device appends information relating to the second device (by way of a Pseudowire switching TLV) to the first message, resulting in a second message. The second message is then forwarded to a third device in the network.

摘要： In one embodiment, an access component of a local network edge device receives traffic, and generates a frame for the traffic that includes a remote context label that identifies an access component of the remote network edge device to which the traffic is to be forwarded upon arrival at the remote network edge device, and a virtual circuit label corresponding to a particular virtual service of the traffic. The local network edge device forwards the frame towards the remote network edge device. In another embodiment, the frame may be received at a core component of the remote network edge device, an in response to the remote context label identifying an access component of the remote network edge device, forwarded to the access component, which determines the particular virtual service, and forwards the traffic from the frame out the access component towards an endpoint for the traffic.

摘要： In one embodiment, a method includes generating an aggregated pseudowire status message at a first network device in a Multi-Protocol Label Switching (MPLS) network, transmitting the aggregated pseudowire status message to a second network device on a Label Switched Path (LSP) extending between the first and second network devices in the MPLS network, and establishing at the first network device, an aggregated pseudowire status session with the second network device upon receiving a response to the aggregated pseudowire status message on the LSP. The aggregated pseudowire status message configured to verify a current status of pseudowires on the LSP. An apparatus is also disclosed.
