rfc3042 (Enhancing TCP's Loss Recovery Using Limited Transmit) says this on page 2, 2nd para: To prevent spurious retransmissions of segments that are only delayed and not lost, the minimum RTO is conservatively chosen to be 1 second. This rfc was published in Jan 2001 -- not an "extremely old" RFC. More like a teenager on the internet time scale. Any way, the collective wisdom seems to say that 1 sec min RTO is _quite_ reasonable. Shouldn't such a change discussion be carried on in freebsd-net (where people who really know TCP may be paying some attention) instead of here? -- bakul To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
