A Survey on Small Group Multicasts
Li Ou · Computer Engineering and Science · 2007
Small group multicasts(SGM) is a main trend of future multicast.Traditional multicast protocols are not fit for very great number of SGMs,so people study protocols which are specially designed for SGM.The main idea of SGM protocols is to heavily reduce the multicast status in the routers and use unicast to implement multicast.The paper discusses and classifies some major SGM protocols,and analyzes their characteristics.The metrics for the evaluation of SGM protocols are summasized,and finally the future trends are explored.
