Multicore Shared-Tree Multicasting - An Efficient Group-Based Load-Shared Approach

摘要

Shared tree multicast approach is preferred over source-based tree multicast because in the later construction of minimum cost tree per source is needed unlike a single shared tree in the former approach. However, in shared tree approach a single core need to handle the entire traffic load resulting in degraded multicast performance. Besides, it also suffers from 'single point failure". In this paper, we have presented two novel and efficient schemes for group-based load shared multicore multicasting in which members of a multicast group use the same core tree for their multicasting.
