  1. Requirements for delivering MPLS services over L3VPNdraft-kumaki-l3VPN-e2e-mpls-rsvp-te-reqts-02.txt Kenji Kumaki KDDI, Editor Raymond Zhang BT 67th IETF@San Diego

  2. Summary of this draft • This draft is to: • Clarify issues for an e2e MPLS TE LSP over BGP/MPLS IP-VPNs • Describe the reference model, application scenarios and specific requirements for these LSPs 67th IETF@San Diego

  3. Reference model P-TE LSPs C-TE LSPs Vrf instances CE PE C C CE PE P P CE CE PE PE Customer’s or another SP’s network Customer’s or another SP’s network Service Provider’s network 67th IETF@San Diego

  4. Application Scenario(1) Priority 0,bandwidth 1M Priority 0,bandwidth 1G SIP proxy server Primary LSP CE2 Customer’s site PE P P User agent client PE CE1 P PE P User agent server PE Customer’s site Backup LSP CE3 SP’s network Customer’s site • The PE should choose an appropriate P-TE LSP based on local policy. • Preemption priority • Voice : priority 0 • The P-TE LSP head-end should control the bandwidth of C-TE LSP. • DS-TE support for C-TE LSPs and P-TE LSPs • Fast protection between CE1 and CE3 • CE1 and CE3 may work as a PCC and PEs may work as a PCE. 67th IETF@San Diego

  5. Application Scenario(2) Priority 1,bandwidth 2G Priority 0,bandwidth 1G Priority 0,bandwidth 100M C1 Primary LSP CE SP B network PE P P C0 PE Backup LSP CE Secondary LSP P PE P PE SP B network Priority 1,bandwidth 200M CE SP A network C2 SP B network • The PE should choose an appropriate P-TE LSP based on local policy. • Preemption priority • Priority 0 : voice • Priority 1 : video and television • The P-TE LSP head-end should control the bandwidth of C-TE LSP. • Fast Protection between CEs (voice) • Load balancing of traffic across primary and secondary LSP to minimize the traffic disruption in case of a link or a PE failure (video and television) • DS-TE support for C-TE LSPs and P-TE LSPs • CEs may work as a PCC and PEs may work as a PCE. 67th IETF@San Diego

  6. Major Changes from -01 • Added two Application Scenarios in Section 5 • Enterprise case • Service Provider case • Added an Application Scenario in Appendix A • RSVP Aggregation over MPLS TE Tunnels 67th IETF@San Diego

  7. Remaining Issues • Any other specific requirements? 67th IETF@San Diego

  8. Next Actions • Need more comments and feedback from WG • Work with other WGs? • Request WG to accept this I-D as a WG document 67th IETF@San Diego
