This email is to ask the working group if RFC 2861 on Congestion Window Validation (CWV) should be left at Experimental, or whether it is time to start the process of moving it to Proposed Standard. RFC 2861, from June 2000, "describes a simple modification to TCP's congestion control algorithms to decay the congestion window cwnd after the transition from a sufficiently-long application-limited period, while using the slow-start threshold ssthresh to save information about the previous value of the congestion window. RFC 2861 also recommends that "the TCP sender should not increase the congestion window when the TCP sender has been application-limited (and therefore has not fully used the current congestion window)". My understanding is that CWV has been included in Linux since Linux 2.4, but that it is not included in Microsoft. Are there any experience reports about CWV (positive or negative), or experience reports of problems (or the absence of problems) for TCP connections without CWV? Or are there other opinions about whether it is time to start the process of moving RFC 2861 to Proposed Standard? Any feedback would be welcome. - Sally http://www.icir.org/floyd/ In the spirit of doing due diligence with old Experimental RFCs... _______________________________________________ tcpm mailing list tcpm@ietf.org https://www1.ietf.org/mailman/listinfo/tcpm
