I'm saying that there's a tradeoff between intra-flow induced latency and packet loss, and I've chosen 4 MTUs as the operating point. Bear in mind that with high packet loss, the retransmissions take an extra RTT to complete in any case, and there's a higher probability of incurring an RTO which will *really* hurt your intra-flow latency. This equation is modified with ECN because a high signalling rate doesn't result in packet loss or retransmissions, but I'm not presently making any decisions based on ECN support, except the obvious one of whether to mark or drop. - Jonathan Morton _______________________________________________ Cake mailing list [email protected] https://lists.bufferbloat.net/listinfo/cake
