  1. Proxy MPLS Traffic Engineering Label Switched Path(LSP)draft-li-mpls-proxy-te-lsp-01 Zhenbin Li, Xinzong Zeng Huawei Technologies IETF 90, Toronto, ON, Canada

  2. Introduction • [I-D.draft-li-mpls-seamless-mpls-mbh-00] introduces the requirement and framework of Seamless MPLS for mobile backhaul networks where MPLS TE is often deployed in for high reliability, QoS, etc. • To achieve the above requirementthis draft proposes a method to setup proxy egress MPLS TE LSP with RSVP-TE signaling protocol which could stitch with BGP LSP to form an end-to-end LSP. • Define a new RSVP-TE object: Proxy Destination Object • Procedures of set up proxy egress TE LSP

  3. Solution of LSP Stitching in Seamless MPLS • Stitch multiple LSP Segments setup by different MPLS signaling protocols • Stitch proxy egress LSP with ingress LSP

  4. RSVP-TE Extension • IPv4 Proxy Destination Object Class-Num = TBD ((of form 0bbbbbbb) 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Length | Class-Num | C-Type (1) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | IPv4 Proxy Destination Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ • IPv6 Proxy Destination Object 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Length | Class-Num | C-Type (2) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | | IPv6 Proxy Destination Address | | | | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

  5. Procedures of set up proxy egress TE LSP PATH message Session Object : tunnel end point address = Remote AN Proxy Destination Object : proxy destination address = AGN PATH message Session Object : tunnel end point address = Remote AN Proxy Destination Object : proxy destination address = AGN AGN AN P Remote AN RESV message Session Object: Proxy Destination Object : same as PATH message RESV message Session Object: Proxy Destination Object : same as PATH message LSP Path message Resv message • Ingress: Use the proxy destination address to calculate path and the setup procedure is the same as current process. • Egress: Identifyitself as the proxy node, stitch the proxy RSVP-TE with the other LSP using tunnel end point address, return RESV message with the same proxy destination object.

  6. Updates • Add one section which is problem statement. • Modify the solution section and procedure section. • Correct text errors.

  7. Next Steps • Solicit more comments on mailing list. • More scenarios will be taken into account.
