Efficient Any Source Capacity-Constrained Overlay Multicast in LDE-Based P2P Networks

Application level multicast has started gaining importance, as it is independent of router infrastructure unlike router-based IP multicast. The existing DHT-based application level multicast protocols work efficiently as long as there is almost no churn; otherwise, their performances start degrading drastically, because DHT - based structured architecture cannot handle churn effectively. Besides, most of these multicast protocols consider single data source and do not consider peer heterogeneity. In this work, we have considered an existing non-DHT based P2P architecture, which has already been shown to perform much better than some well-known DHT-based architectures from the viewpoints of speed of unicast communication and churn handling. Here, we have presented a highly efficient capacity-constrained and any source multicast protocol suitable for the non-DHT based P2P architecture as mentioned above.
