Performance evaluation of the DCCP protocol in high-speed networks

The Internet transport layer protocols, TCP and UDP, do not provide an efficient transport for multimedia streams. In despite of that, UDP is often employded for such type of application, due to its low overhead. Since UDP does not implement any kind of congestion control mechanism, it has the potential of hindering Internet operability. To address such issue, a novel transport layer protocol, namely DCCP, has been proposed. It is designed to be used by multimedia applications with the aim of replacing the UDP protocol. This paper conducts a performance evaluation of the DCCP protocol in high-speed networks. The aim is to evaluate the scalability, the fairness, the convergence and the compatibility with TCP-Reno.
