I have just submitted a revised internet-draft for "Adding Acknowledgement Congestion Control to TCP", available from "http://www.icir.org/floyd/papers/draft-floyd-tcpm-ackcc-01.txt". The revisions, listed below, are based largely on feedback from Armando Caro and Mark Allman. Further feedback would be welcome. To the TCPM co-chairs: Can we have a slot at the July IETF to talk about this? I would probably be the presenter. The goal is for this to be taken up as a WG item for consideration as an Experimental RFC. - Sally http://www.icir.org/floyd/ Changes from draft-floyd-tcpm-ackcc-00.txt: * Added a discussion of environments where the reverse path is congested, but the TCP ACK traffic does not significantly contribute to that congestion. In this case, the goal is to minimize the negative impack of AckCC on TCP performance. Feedback from Armando Caro. * In Section 5.7, added that when ABC is used with Aggregate Congestion Control, and rate-based pacing is also used, the sender MAY increase cwnd by more than 2 MSS. Feedback from Armando Caro. * Added a section about measurements of ACK traffic and congestion. Feedback from Armando Caro. * Added a section on the possibility of a TCP receiver-imposed lower bound on the ACK Ratio. Suggested by Mark Allman. * Added to the discussion of the mimumum ACK sending rate. Suggested by Mark Allman. * Added a note that if the TCP receiver doesn't sent an ACK for every duplicate data packet, the sender's Fast Recovery procedure will have to be modified to take this into account. Feedback from Mark Allman. * Added a discussion of evaluating ACK Congestion Control. From feedback from Mark Allman. * Some general editing in response to feedback from Mark Allman. _______________________________________________ tcpm mailing list tcpm@ietf.org https://www1.ietf.org/mailman/listinfo/tcpm
