Many new applications in networks require support for multicast communication. In addition, continuous data streams such as audio and video require real-time performance guarantees as a quality of service. We introduce a model for real-time mulitcast channels and present a set of scalable algorithms for the dynamic joining and leaving of destination nodes in this environment. In particular we present an algorithm for finding a good attachment point to the multicast tree. We also describe detailed admission tests that preserve the guarantees given to existing channels. Our algorithm for a leaving node specifies in particular the resources to be released in the network. We also discuss tree reorganization issues.
