Group Management for the Multimedia Broadcast/Multicast Service
George Xylomenos · 2005
This paper compares the group management mech- anisms used in the IP and the MBMS multicasting models. After outlining the design of each model, we describe the group management protocols that they employ. We then examine how the IP group management protocols can be adapted for MBMS and finally evaluate the group management approach adopted by MBMS. Our main findings are that IGMP v.2 is preferable for use with MBMS, that the join/leave group management approach of MBMS outperforms the query/report approach of IP and that the reliability of the MBMS approach can be enhanced by upcalls.
