Abstract

The Datagram Congestion Control Protocol (DCCP) has been proposed as a transport protocol which supports real-time traffic using window-based flow control. We investigate the DCCP performance for various traffic flows, focusing on how DCCP flows affect TCP flows and vice versa. Through those simulations, we examine an unfair bandwidth distribution problem caused by the incompatibility of DCCP with the fast recovery algorithm of TCP.
