There is no way to `calculate' the maximum segment lifetime unless you are omniscient. It is assumed to be 30 seconds, but in reality can be much, much more. (As a result, TCP is theoretically broken, but the situations in which this happens are rare enough to be masked by other events.) The RTT gives you the *critical path length* of the graph; it does not have anything to do with the MSL except for trivial (two-node) networks. -GAWollman To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
