Hi, I just had a friend ask me a weird question about ICMP source quench and its handling in various OS's. He proceeded to show me a part of some version of the Linux kernel source, which processed a source quench request properly, yet had a 'This is deprecated' comment at the top. I had a quick look at src/sys/netinet/tcp_subr.c, and on FreeBSD 4.x and -current, an ICMP source quench seems to provoke a proper downsizing of the connection window. Is there any reason for ICMP source quench to be deprecated? If so, what is it to be replaced with? Or are the TCP window scaling algorithms smart enough to downsize the window quick enough in case of a noticeable packet loss? (I guess they should be..) G'luck, Peter -- If I were you, who would be reading this sentence? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
