I was also considering adding the option to irtt for different packet sizes in each cluster. I’d have to change the IPDV calculation to only calculate it for like-sized packets, which is possible. I see how using the RTTs for different packet lengths might help estimate the transmission time, but not how I could use that to differentiate between channel contention and queueing delays(?) Maybe I see what you’re saying, that in addition to varying the DSCP value, I can also vary length to estimate the transmission time, and subtract that from the estimate I get for “contention” to have a better approximation of how much contention time there is, which sounds like a good idea... :) I don’t know of any bonded segments in this case… _______________________________________________ Flent-users mailing list Flent-users@flent.org http://flent.org/mailman/listinfo/flent-users_flent.org
