Inter-Domain TE PW Signaling using RSVP-TE Overview Instantiate a multi-segment PW as a RSVP-TE LSP Two unidirectional LSPs or one bi-directional LSP – PW ID TLV along with the SESSION & SENDER_TEMPLATE identifies the PW This “PW LSP” is nested in intra-domain PSN RSVP-TE LSPs between PW segment end-points Targeted RSVP-TE signaling messages between PW segment end-points QoS signaling using TSPEC etc PW Explicit/Record routing using ERO/RRO Single sided signaling possible to ensure the same MS PW path in both directions Resiliency using Fast-Reroute - draft-ietf-mpls-rsvp-te-fast-reroute MS PW Path computation and routing follows inter-domain RSVP-TE |
