RVP : A New Policy for Aggregate Reservation

Free registration required

Executive Summary

Reservation aggregation provides scalability to the IETF Integrated Services (IntServ) by reducing the high number of states stored at internal routers and the number of signalling messages processed at these routers. However, the latter benefit will be lost if the bandwidth of aggregate reservation changes frequently. Hence, previous works either hold resource requests during a waiting period before sending a single aggregate reservation for all received requests, or reserve maximum resources which will be requested in the following period. However, these works involve an assumption of arrival distribution of resource requests.
