The Internet community has proposed the Integrated Services architecture Intserv and the signaling protocol RSVP to provide deterministic guarantees bandwidth, delay and jitter to individual flows. However, experience with practical systems has revealed the severe scalability problems of the Intserv model due to the amount of routing and reservation state that is required to be maintained in the routers. A natural approach to improving scalability of Intserv architecture is through reduction of amount of state in the routers by using aggregated flow state instead of per-flow state. We present a novel architecture that uses very light state in the routers, while still providing the deterministic guarantees of the Intserv model.
