RP reselection scheme for real-time applications in delay-constrained multicast networks
Dong-Lim Lee, Chan‐Hyun Youn, Sangjin Jeong · 2003
Many works have shown that shared tree-based multicast outperforms a source-based tree in scalability. Generally, there has been much research under QoS constraints for rendezvous point (RP) selection and reselection as the multicast group members join and leave dynamically during a session. We propose both new initial RP selection and RP reselection schemes which use RTCP (real-time control protocol) report packet fields. Simulation results show that the proposed schemes have better performance than conventional algorithms.
