The Scalable Reservation Protocol (SRP) provides a light-weight reservation mechanism for adaptive multimedia applications. Our main focus is on good scalability to very large numbers of individual flows. End systems (i.e. senders and destinations) actively participate in maintaining reservations, but routers can still control their conformance. Routers aggregate flows and monitor the aggregate to estimate the local resources needed to support present and new reservations. There is neither explicit signaling of flow parameters, nor do routers maintain per-flow state.

throughput versus delay jitter differentiated service for IP packets. With this service, every best effort packet is marked as either green or blue. Green packets, typically sent by real-time applications such as interactive audio, receive more losses during bouts of congestion than blue ones. In return, they receive less delay jitter. Both green and blue services are best-effort. The incentive to choose one or other is based on the nature
