This paper introduces a flexible new method of constructing hierarchical multicast structures suitable for supporting large-scale GRID applications. Hierarchical multicast trees are constructed by repeated application of clustering algorithms that partition the members of a large application community to form a layered hierarchy of clusters of users. The(More)
The Universe network is being used to explore broadcasting techniques in a highly integrated computer communications experiment connecting local area networks via a broadcast satellite channel. The broadcast protocol which has been devised within the Project provides a versatile framework in which different types of broadcast applications can be carried(More)
Conventional delivery mechanisms for many-to-many multicast services consider either a single shared tree or a source rooted trees approach. These two mechanisms complement each other in terms of performance and protocol complexity. In this paper, we describe a design that uses multiple shared trees that would provide a balance between these two extreme(More)
