I think this would be a good idea to add this as an option. This option could be an alternative to interactive applications that use CCID 3. -Arjuna On 11/6/06, Sally Floyd <sallyfloyd@xxxxxxx> wrote:
It would be a simple change to add an option to CCID 2 to have the sender use different AIMD parameters. The obvious possibility would be for the slowly-responding option to use AIMD (1/5, 1/8) instead of AIMD(1, 1/2). This means that the congestion window would be increased by 1/5 of an MSS rather than by one MSS per round-trip time, and after loss events the congestion window would be decreased to 7/8-ths of its old value, not to half of its old value. This would differ from the regular CCID 2 by being slowly-responding, and would be somewhat similar in its time scales to CCID 3. This is discussed in some detail in the following: A Comparison of Equation-Based and AIMD Congestion Control. Floyd, S., Handley, M., and Padhye, J. May 2000. URL "http://www.icir.org/tfrc/" Is this worth doing? It would be very simple to specify, and very simple to implement. And it shouldn't have too many surprises in its dynamics. - Sally http://www.icir.org/floyd/
