  2. RSVP Proxy Background • RSVP deployments happening: • eg for Voice/Video CAC on WAN in Enterprise • eg for VoD CAC on Aggregation in Triple-Play SP • RSVP also considered: • eg for Mobile Voice CAC on Radio • Many deployment scenarios involve RSVP only on a subset of end-to-end path • non-RSVP-capable Sender, or non-RSVP-capable Receiver • RSVP CAC only needed on (radio) access • Current RSVP spec assumes end-to-end signaling • Need to : • document (resurrect) non end-to-end deployment approaches • standardize corresponding extensions (where needed) • NSIS included this in base specs

  3. VoD RSVP Path Video Stream RSVP Resv Use Case: VoD CAC on Aggregation in Triple Play RSVP aware RSVP Receiver Proxy RSVP aware Residential L3 IP/MPLS Core Ethernet/IP/MPLS Aggregation Business RSVP Unaware Corporate 802.1Q

  4. Use Case: Voice/Video CAC on WAN in Enterprise SIP Server SIP HQ SIP RSVP Proxy RSVP Proxy WAN RSVP RSVP aware Location B Location A RSVP Unaware

  5. VoD Example of required RSVP Extension RSVP Receiver Proxy • Regular RSVP sends CAC reject notification towards Receiver • RSVP Receiver Proxy can not do much with it • Extension to notify Sender of CAC reject RSVP Unaware RSVP aware Path Resv CAC reject ResvErr (CAC reject) ??? PathErr (CAC reject)

  6. I-Ds Roadmap • As announced on mailing list after Montreal • draft-lefaucheur-tsvwg-rsvp-proxy: • Provides Framework for RSVP Proxy concept • Taxonomy of (useful) Proxy Approaches • Minor RSVP extensions for simple Proxy approaches • Use Cases (in Appendix) • draft-manner-tsvwg-rsvp-proxy-sig ("Localized RSVP for Controlling RSVP Proxies”) : • Specifies RSVP signaling extensions for more complex Proxy approaches (RSVP-Signaling-Triggered Proxy)

  7. Taxonomy of Proxy Approaches: • Path-Triggered Receiver Proxy • Path-Triggered Sender Proxy for Reverse Direction • Inspection-Triggered Proxy • STUN-Triggered Proxy • Application-Signaling-Triggered On-Path Proxy • Application-Signaling-Triggered Off-Path Source Proxy • RSVP-Signaling-Triggered Proxy

  8. Next Steps • Progress RSVP Proxy under TSVWG • Address comments received • Should rsvp-proxy target Informational Track or Standards Track? • If Informational, need to move minor “extensions” out of rsvp-proxy I-D. • Should all extensions go to rsvp-proxy-sig or to separate I-Ds for different Proxy approaches?
