Host A:10000 talks to Host B:20000 (10000 and 20000 being ports) and it gets logged in tcp's hostcache.
Now if a new connection happens between A:10001 and Host B:20000, the initcwnd (initial congestion window) would not look at the CWND from hostcache but will always use what we've set as tp->snd_cwnd in cc_conn_init() of tcp_input.c - is this a correct assumption? What I want to confirm is, whether hostcache has any effect on initial congestion window of a new connection being setup. >From my reading of the code, cc_conn_init() always happens before we call tcp_hc_get() to get data out of hostcache to update other parameters of a connection. I do not see hc_entry->rmx_cwnd being actually used anywhere in tcp_input.c while connection bring up. Am I missing anything? cheers, Hiren _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
