Datagram Congestion Control Protocol (DCCP)<br />
● Key motivation<br />
● rapid growth of applications using UDP<br />
● streaming media, on-line games, internet telephony<br />
● apps preferring timeliness instead of reliability or short start-up delay<br />
● non TCP-friendly behavior of UDP poses threat to the health of the Internet<br />
● clean, understandable, low-overhead, minimal protocol<br />
● Key features<br />
● unreliable flow of datagrams, end-to-end congestion control, simpler firewall<br />
traversal, parameter negotiation<br />
● RFCs<br />
● RFC 4340, updated by 5595, 5596, 6335<br />
● RFC 4336: Problem Statement for the Datagram Congestion Control Protocol<br />
