Abstract

An increasing number of networking applications involve multiple participants and are therefore best supported by multicasting. Where multicast applications consume high bandwidth, it is important to minimise the effect on the network by offering economical multicast routes. Many new applications involve real-time components and are therefore also delay-sensitive. This paper discusses reasonably simple techniques for multicast routing which tackle both of these constraints, that is: first, the route makes efficient use of network resources and, secondly, delays to all recipients are kept within a bound. The problem is NP-complete, so we present heuristics which build up a directed graph containing potential routing solutions and use a greedy approach to select a solution from that graph. The heuristics are discussed and evaluated and are shown to offer good results for a variety of situations including both small and large multicast groups. Our approach is also compared with a previous solution to this problem, which has a greater time complexity.
