Abstract

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 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.

     Quick-Start for the Datagram Congestion Control Protocol (DCCP)

Abstract

   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 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.
