Overlay multicast protocols should adapt to the dynamic network environment. We study how the use of the end-to-end network metric in the dynamic adaptation improves the performance of the direct-tree overlay multicast protocols as well as provides good tree quality. We propose the Adaptive Overlay Multicast (AOM) approach that provides good tree quality and efficient adaptation. We compare AOM with a typical direct-tree protocol like HMTP. The simulation results show that AOM buildsdoi:10.1109/ccnc.2004.1286850 dblp:conf/ccnc/WuB04 fatcat:xtuqml6pc5gj7jaimkswbpnvgi
