The Multicast Scheme of ATM Networks for Multimedia Transmissions Based on SD Channel
Ting Wang, Jianzhong Hao, Zhuo Li, Shuling Wang, Wei Yan · 2012
In this paper, we propose a bi-directional multipoint-to-multipoint multicast scheme, a SD channel-based Multicast with Round robin Access (SDRAM), for ATM networks, which uses a single tree for a multicast group consisting of multiple participants that are either senders, receivers, or a mix of both.We first discuss why the resequencer model will not be suitable for multimedia traffics, and then propose the SDRAM scheme to solve the problems, and finally compare our scheme with the resequencer model through simulation.Results show the mean queuing delays and mean inter-PDU delays of our scheme are not sensitive to mean PDU size while the mean queuing delays and mean inter-PDU delays of the resequencer scheme are very sensitive to mean PDU size.Index Terms-ATM, multicast, resequencer, round robin, shared tree.
