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 on-line 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 application-
limited 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.
