This website contains references to work we have done on a newly proposed Internet transport protocol, the Datagram Congestion Control Protocol (DCCP, formerly DCP), which is motivated by a real-time application's need for a way to send and receive an unreliable stream of data, yet still have a congestion control mechanism that allows it to compete fairly with other flows in the network. Most of our work has focused on the implementation of DCCP.
