2. 222 IETF67/TSVWG: RSVP Proxy 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

6. 666 IETF67/TSVWG: RSVP Proxy 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. 777 IETF67/TSVWG: RSVP Proxy 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. 888 IETF67/TSVWG: RSVP Proxy 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?
