Quick-Start for the Datagram Congestion Control Protocol (DCCP)
Gorry Fairhurst, Arjuna Sathiaseelan · 2009
This document specifies the use of the Quick-Start mechanism by the Datagram Congestion Control Protocol (DCCP).DCCP is a transport protocol that allows the transmission of congestion-controlled, unreliable datagrams.DCCP is intended for applications such as streaming media, Internet telephony, and online games.In DCCP, an application has a choice of congestion control mechanisms, each specified by a Congestion Control Identifier (CCID).This document specifies general procedures applicable to all DCCP CCIDs and specific procedures for the use of Quick-Start with DCCP CCID 2, CCID 3, and CCID 4. Quick-Start enables a DCCP sender to cooperate with Quick-Start routers along the end-to-end path to determine an allowed sending rate at the start of a connection and, at times, in the middle of a DCCP connection (e.g., after an idle or applicationlimited period).The present specification is provided for use in controlled environments, and not as a mechanism that would be intended or appropriate for ubiquitous deployment in the global Internet. Status of This MemoThis memo defines an Experimental Protocol for the Internet community.It does not specify an Internet standard of any kind.Discussion and suggestions for improvement are requested.Distribution of this memo is unlimited.
