2. 222 Changes from Previous version De-correlate the generic aggregate reservations from IPsec operations: – remove SPI from Sender-Template, remove PID from Session – in line with agreement reached after Security experts review – considerably simplifies the document in many places. Add the notion of Extended Virtual Destination port – reusing the notion of Extended Tunnel ID of [RSVP-TE] – very convenient mechanism to make Session unique to Agg/Deagg pair Add recommendations on use of IP addresses by Aggregator and Deaggregator – implementation experience from RFC3175

6. 666 Use Case: Parallel Aggregate RSVP Reservations R1 R4 R3 R2 R6 R5 P1 P2 R7 RSVP Aggregators Aggregation as per RFC3175 Need for Multiple Aggregate reservations for a given tuple (use a different VDstPort) Preemption conveyed using RFC3181 Preemption Priority Policy Element Agg RSVP Resa : Voice/EF + High Preemption End-to-end RSVP reservation + High Prempt Need for Parallel Aggregate Reservations Intserv/Diffserv Cloud Agg RSVP Resa : Voice/EF + Low Preemption End-to-end RSVP reservation + Low Preempt

7. 777 Use Case: Nested VPN (draft-ietf-tsvwg-vpn-signaled-preemption-xx.txt “QoS Signalling in a Nested VPN”) R1 R4 R3 R2 R6 R5 P1 P2 R7 IPsec VPN Routers IPsec VPNs, with need for end-to-end RSVP reservations:  e2E reservations must be hidden/aggregated over IPsec tunnels  resources must be reserved (by RSVP) in the Diffserv Cloud for traffic carried over a given IPsec tunnel (eg for Voice traffic, for Video traffic) IPsec tunnel End-to-end RSVP reservation Intserv/Diffserv Cloud Need for Aggregate Reservations (in Diffserv cloud) for IPsec tunnels
