Abstract

An overlay multicast is proposed to solve the scalability and deployment problems in IP Multicast. We propose a scheme, Topology-aware Load-balance Hierarchical Independent Tree (TLHIT), with topology-aware, load-balance and path diversity properties to improve the performance of overlay multicast. Compared to traditional methods, the proposed TLHIT constructs not only node-disjoint but also path-disjoint multicast trees where each node serves as an interior node in only one tree and different trees do not contain the same path. Moreover, TLHIT ensures load-balance property by building the multicast trees based on n-ary full tree. It ensures that each node serves almost the same amount of child nodes. Simulation results show that the reliability, efficiency, and load-balance properties of the proposed TLHIT are assured.
