Well, thats a huge way to favor non ECN flows against ECN flows. Marking _all_ ECN enabled packets just because last packet sent had a sojourn time above target is going to throttle ECN flows and let non ECN flows going full speed and take whole bandwidth. Doing so is a nice way to keep users switching to ECN one day. IETF could just say : ECN is doomed, forget about it, dont even try. _______________________________________________ Codel mailing list [email protected] https://lists.bufferbloat.net/listinfo/codel
