Abstract
The Int-Serv and Diff-Serv differentiation approaches, which have been proposed by the IETF, are in practice unable to provide QoS guarantees to the emerging multicast-enabled applications by means of a scalable mechanism able to support QoS services on a per-call basis and dynamic group memberships. This paper describes a newa pproach that is capable of ensuring bandwidth guarantees to multicast sessions on IP-based networks and satisfies the above requirements. It includes a scalable, end-to-end Call Admission Multicast Protocol (CAMP) that operates as a sort of distributed bandwidth broker and allows to combine the benefits of both the IS and DS approaches in a single approach which is simple, scalable, operates on a per-call basis and supports the group membership dynamics.
This work was supported by the MURST under Contract no.9809321920 “Transport of multicast packets with QoS guarantees”.
