Abstract
Abstract- This paper describes the integration of a TCPfriendly mechanism into RTP. We discuss why the integration is favorable over a solution in which RTP and TCP-friendly mechanisms are separated from each other. During the design of the TFRC integration we took into account that caches should be integrated to create a TCP-friendly and scalable video distribution system. With the notion that caches are often placed very close to clients and that these clients will be in many cases connected to the caches via dedicated links (ADSL, cable modem) we present a solution where the connection between server and cache is TCP-friendly and the one between the cache and the client is not necessarily congestion-controlled. We further show how with the aid of an RTSP extension both peers of the link can negotiate the kind of transmission (congestion controlled or not), thus allowing the usage of standard and commercial clients and performing congestion control on the crucial part between server and client. In addition to the design of such an integration we have also implemented the TCPfriendly mechanism in our own streaming environment and present experimental resukts based on this implementation.
