659	I think it should be interesting to investigate efforts on a protocol that is enable to cope with TCP limitations. up to now this type of protocol has been...	Dean Martin deanmartin_fr@...	Jul 22, 1999 6:57 pm
660	Dean- Well, it depends by what you mean 'TCP limitations.' If by that you mean something like stop-and-wait behavior when more than one packet is lost in a ...	Falk, Aaron afalk@...	Jul 22, 1999 10:20 pm
661	thanks for the feedback, i agree that techniques such as spoofing (splitting the tcp connection) from companies mentioned like flash-networks & mentat, and...	ketan bajaj ketan_bajaj@...	Jul 23, 1999 9:13 am
662	Hi The terms spoofing has different meaning and generally denotes systems which send false acknowledgements to the end node to trick it into sending data...	Dean Martin deanmartin_fr@...	Jul 23, 1999 11:30 am
663	... In the absense of explicit information, the sender must assume that a lost packet is an indication of congestion. You can't change this aspect of TCP,...	Jamshid Mahdavi mahdavi@...	Jul 23, 1999 4:27 pm
664	This is an issue that would be helped by good ECN and new sender code, if the sender then could assume lack of ECN implies error loss -- thus keep sending with...	Alex Cannara cannara@...	Jul 23, 1999 5:33 pm
665	Note that spoofing has been around for many years for LAN protocols, such as LLC, where folks like Cisco create effectively routed links for unroutable...	Alex Cannara cannara@...	Jul 23, 1999 5:53 pm
666	Oh, don't I wish. Unfortunately, packets carrying CE bit set are just as likely to be lost due to congestion as any other packet, so that the lack of ECN means...	Spencer Dawkins sdawkins@...	Jul 23, 1999 7:43 pm

670	Jamshid, I agree, the use of some mechanism that makes a clear distinction between loss and congestion available to the sender is what would make things much...	Alex Cannara cannara@...	Jul 24, 1999 5:13 am
671	Spencer, yes I wasn't suggesting ECN as "the defined standard", and wasn't even aware of all the problems with it you mention. I'm just hoping for something...	Alex Cannara cannara@...	Jul 24, 1999 5:18 am
