A TCP-friendly rate adjustment protocol for continuous media flows over best Effort networks

摘要

As netwroked ocntinuous media (CM) applications become widespread,it becomes increasingly important to ensure that they incorportte soem form of congestion control mechanism,in order to co-exist with each other and with current TCP-based applications.Since CM applciatiosn must co-exist with TCP -based applications,CM congestion control algorithms should be "TCP-friendly".One definition of TCP "friendliness" is given in [2] - if a CM ocnnection shares a bottleneck link with TCP connections traveling over the same network path,then the CM connection should receive the same share of bandwidth (i.e.,achieve the sme throughput) as a TCP connection.A first step then in developing a CM congestion conttol protocol,is to investigate cntestion control protocols that set their transmission rate in a TCP -reficendly manner.
