We have just revised and submitted our old, expired draft for Quick-Start. It should appear in the internet-drafts repository in a few days, but until then, it is available from the following: http://www.icir.org/floyd/papers/draft-amit-quick-start-03.txt http://www.icir.org/floyd/papers/draft-amit-quick-start-03.ps Any feedback would be appreciated. We would like to talk about this at the next tsvwg meeting, if possible, and would like to start the process to see if this could become an official work item for tsvwg. Many thanks, - Sally http://www.icir.org/floyd/ Quick-Start for TCP and IP: Abstract This draft specifies an optional Quick-Start mechanism for transport protocols, in cooperation with routers, to determine an allowed sending rate at the start and at times in the middle of a data transfer. While Quick-Start is designed to be used by a range of transport protocols, in this document we describe its use with TCP. By using Quick-Start, a TCP host, say, host A, would indicate its desired sending rate in bytes per second, using a Quick Start Request option in the IP header of a TCP packet. A Quick-Start request for a higher sending rate would be sent in a TCP packet. Each router along the path could, in turn, either approve the requested rate, reduce the requested rate, or indicate that the Quick-Start request is not approved. If the Quick-Start request is not approved, then the sender would use the default congestion control mechanisms. The Quick-Start mechanism can determine if there are routers along the path that do not understand the Quick- Start Request option, or have not agreed to the Quick-Start rate request. TCP host B communicates the final rate request to TCP host A in a transport-level Quick-Start Response in an answering TCP packet. Quick-Start is designed to allow connections to use higher sending rates when there is significant unused bandwidth along the path, and all of the routers along the path support the Quick-Start Request. _______________________________________________ tsvwg mailing list tsvwg@ietf.org https://www1.ietf.org/mailman/listinfo/tsvwg
