So a set of APIs must be defined. They should be downward-compatible with basic socket
APIs supporting TCP.
Because ATP is optimzed for IPv6, a

General Question:
- How to migrate?
I have been using the "QWERTY" keyboard all the time.
I am aware that it is not the best, but I am stuck.

Sure, but it wasn't using TCP...

I think it would be very difficult to replace TCP. However, a new
transport protocol that worked better than TCP in very high bandwidth /
low delay conditions might be very attractive for hosts and applications
that were able to take advantage of it.
I don't agree that abundant IPv6 addresses r

At SC2000 there was an application (non-interlaced HDTV) using
1.5Gbps.

For slow links, maybe. But TCP's congestion avoidance algorithm does
make the assumption that 90%+ of the losses are caused by congestion,

But ECN seems to address this issue, and it can work for UDP as well
as TCP.

The host *is* the edge of the network.
