  2. History berger-ccamp-assoc-info-00 narayanan-tsvwg-rsvp-resource-sharing-01 • Non-GMPLS “Resource Sharing” Association • Upstream Association • Extended Association ID • ASSOCIATION Object as defined in RFC 4872 and RFC 4873 IETF 76 • Resource Sharing Remote Identification Association narayanan-tsvwg-rsvp-resource-sharing-02 berger-ccamp-assoc-info-01 • Resource Sharing Remote Identification Association • ASSOCIATION Object as defined in RFC 4872 and RFC 4873 • Non-GMPLS “Resource Sharing” Association • Upstream Association • Extended Association ID IETF 77

  3. Summary • Extension to draft-berger-ccamp-assoc-info • Standards Track • defines a new association type called "Resource Sharing Remote Identification"

  4. Resource Sharing Remote Identification association • can be used by the sender to convey to the receiver information that can then be used by the receiver to identify an upstream initiated resource sharing • useful in upstream initiated resource sharing applications where the identification of the resource sharing association is not known a priori by the receiver, and instead is known by the sender • type-specific association rule: The Resource Sharing Remote Identification association does not create any association across Path states.

  5. Resource Sharing Remote Identification association Resv(RS, ID=S/100) Path (RSRID, ID=S/100) Receiver1 Cloud of RSVP Routers Sender Receiver2 Path (RSRIS, ID=S/100) Resv(RS, ID=S/100) Resource Sharing across the two reservations RSRID = “Resource Sharing Remote Identification” association RS= “Resource Sharing” association ID= Association Identification

  8. Recap of problem • Currently RSVP flows with different SESSION objects cannot share resources • There are some use cases where this is important • Symmetric NAT • VoIP call sharing • Proposed solution: separate resource sharing from SESSION object

  9. Problem: VoIP features • Sharing bandwidth between calls currently in call-waiting • Shared calls between shared-line extensions at different locations • Sharing not possible in RSVP for reservations going to different {L3,L4} destinations A Share? B C

  10. Problem: Symmetric NAT • Unidirectional flows to the same destination, traversing symmetric NAT • NAT issues different destination ports to the different senders • Sharing not possible in RSVP for reservations going to different {L3,L4} destinations A Symmetric NAT Share? B C
