Is there a groundswell of *operators* who think TCP should be replaced, and believe it can be replaced? Or is the motivation for replacing TCP mainly felt by those who spend a lot of time trying to get maximum performance out of single flows over high bandwidth-delay product paths?
Operators speak IP, not TCP -- not your problem... More seriously -- the question is whether new services will cause operator congestion problems that today's mechanisms don't handle. It's also possible, per the note that some solutions will have operator implications, such as new tuning knobs for routers and/or new funky new DNS records to make it clear which hosts support TCP++. Beyond that, there are likely implications for things like firewalls, ACLs, and service measurements. --Steve Bellovin, http://www.cs.columbia.edu/~smb
