Multicast applications, including audio and video, are expected to consume a large fraction of resources in forthcoming high speed networks. Because of this, new services are needed to provide the quality of service (QoS) required by these applications. In this paper we take a step in this direction by presenting a general framework for admission control and resource reservation for multicast sessions. Within this framework, efficient and practical algorithms that aim to efficiently utilize network resources are developed. The problem of admission control is decomposed into several subproblems that include: the division of end-to-end QoS requirements into local QoS requirements, the mapping of local QoS requirements into resource allocation, and the optimization of the resulting resource allocation for a multicast session. These are solved independently of each other yielding a set of mechanisms and policies that can be used to provide admission control and resource reservation for multicast connection establishment. A comprehensive application of an instance of the algorithms in the context of packetized voice multicast connections over the Mbone is provided to illustrate their applicability.
