Abstract
In a multicast network, a method is employed for selecting a low cost multicast conference tree subject to an end-to-end delay constraint for transmissions between any two nodes in the tree that terminate conference participants. The method employs a constrained minimum cost Steiner tree selection technique that integrates facilities costs and a delay constraint into a single objective function to be minimized as the tree is incrementally configured. The method also incorporates a unique path delay metric (delta diameter) that indicates the effect on end-to-end delay resulting from the incremental addition of a next node to the Steiner tree.
