Congestion control for reliable multicast achieving TCP fairness

摘要

In the paper, we propose a congestion control scheme for reliable multicast communication which enables TCP fairness and prevents a drop-to-zero problem. The proposed con- gestion control scheme is rate-based one based on NAKs from re- ceivers and cooperatively works with a flow control scheme. The congestion control scheme consists of two components of a rate- based controller and a selection mechanism of a representative. The rate-based controller runs between the sender and the rep- Resentative and achieves TCP fairness and fast response to losses At the representative.
