Follow-up Comment #6, bug #27783 (project lwip): Sounds reasonable. Only downside is it makes it a little harder to reason about when people report problems. I guess it might also be arguable that with a small window having lots of ACKs is a good idea. I think on balance your suggestion is a good idea. I just find it odd that we need a special case for this small range of window sizes. One other thing: for TCP_WND = 4MSS we get a threshold of MSS. for TCP_WND = 4MSS - 1 we get a threshold of 2MSS. That big step seems wrong: why not set it to MSS for WND < 4MSS? That would make it better at TCP_WND = 2MSS too: you'd have a threshold of MSS (i.e. less than the TCP_WND) instead of 2MSS (same as the TCP_WND) _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?27783> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
