This document specifies TCP-Friendly Multicast Congestion Control(TFMCC). TFMCC is a congestion control mechanism for multicasttransmissions in a best-effort Internet environment. It is a single-rate congestion control scheme, where the sending rate is adapted tothe receiver experiencing the worst network conditions. TFMCC isreasonably fair when competing for bandwidth with TCP flows and has arelatively low variation of throughput over time, making it suitablefor applications where a relatively smooth sending rate is ofimportance, such as streaming media. This memo defines an ExperimentalProtocol for the Internet community.
