A Weighted Selection Function-based Application Layer Multicast Routing Algorithm

Though the efficiency of IP-based multicast is undeniable,the deployment of IP multicast has met many difficulties.Application layer multicast (ALM) is an alternative which enables rapid deployment of multicast applications in Internet.This paper proposes a distributed application layer multicast routing algorithm based on weighted selection function.It tries to avoid local triangle routing problem and takes proximity into consideration when constructing a multicast tree.Simulation results show it is a practical theme.
