That's true, has been for quite some time, and yet nobody seems to be doing much about it. Which makes you wonder how big of a problem that is in practice. If applications were really hurting, you would hear complaints from application developers. But you don't. The applications that need reliable long duration sessions incorporate some trivial checkpoint and restart mechanism, or some pretty elaborate consistency protocols for big databases. They probably would do that no matter what the reliability of TCP, as long as it is not "perfect." And PA renumbering is probably not very high in their list of "stuff that occasionally break TCP." -- Christian Huitema _______________________________________________ rrg mailing list rrg@irtf.org http://www.irtf.org/mailman/listinfo/rrg
