November th Diego Requirements for delivering MPLS services over L3VPN draft-kumaki-l3VPN-e2e-mpls-rsvp-te-reqts-02.txt Kenji Kumaki KDDI, Editor Raymond Zhang BT

November th Diego 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

November th Diego Reference model Service Provider’s network Customer’s or another SP’s network Customer’s or another SP’s network P-TE LSPs Vrf instances C-TE LSPs CE C C PE PP

November th Diego Application Scenario(1) 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. SP’s network CE1 PE CE2 CE3 Customer’s site P P P P SIP proxy server User agent client User agent server Primary LSP Backup LSP Priority 0,bandwidth 1M Priority 0,bandwidth 1G

November th Diego Application Scenario(2) SP A network CE PE CE SP B network C0 C1 C2 P P P P Priority 0,bandwidth 1G Priority 1,bandwidth 2G Priority 0,bandwidth 100M 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. Priority 1,bandwidth 200M Primary LSP Secondary LSP Backup LSP

November th Diego 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

November th Diego Remaining Issues Any other specific requirements?

November th Diego Next Actions Need more comments and feedback from WG Work with other WGs? Request WG to accept this I-D as a WG document
