document: FLID-DL : congestion control for layered multicast We describe fair layered increase/decrease with dynamic layering -LRB- FLID-DL -RRB- : a new multirate congestion control algorithm for layered multicast sessions . FLID-DL generalizes the receiver-driven layered congestion control protocol -LRB- RLC -RRB- introduced by Vicisano et al. -LRB- Proc . IEEE INFOCOM , San Francisco , CA , , p.996-1003 , Mar. 1998 -RRB- ameliorating the problems associated with large Internet group management protocol -LRB- IGMP -RRB- leave latencies and abrupt rate increases . Like RLC , FLID-DL , is a scalable , receiver-driven congestion control mechanism in which receivers add layers at sender-initiated synchronization points and leave layers when they experience congestion . FLID-DL congestion control coexists with transmission control protocol -LRB- TCP -RRB- flows as well as other FLID-DL sessions and supports general rates on the different multicast layers . We demonstrate via simulations that our congestion control scheme exhibits better fairness properties and provides better throughput than previous methods . A key contribution that enables FLID-DL and may be useful elsewhere is dynamic layering -LRB- DL -RRB- , which mitigates the negative impact of long IGMP leave latencies and eliminates the need for probe intervals present in RLC . We use DL to respond to congestion much faster than IGMP leave operations , which have proven to be a bottleneck in practice for prior work
