The Datagram Congestion Control Protocol (DCCP) [1] is being proposed by IETF as a transport protocol to support multimedia traffic. Two congestion controls mechanisms have been proposed so far for DCCP, namely TCP-Like [2] and TCP-Friendly Rate Control (TFRC) [3]. In this paper, we experimentally investigate the DCCP performance with its two congestion control algorithms for two kinds of video streaming applications, those using XVID [4] and MPEG [5] codecs. The first stream want to make quick use of any available bandwidth, while the second prefer to minimize abrupt changes in the sending rate. Our results confirm these preferences for each stream regard to DCCP congestion controls.
