Eric,

No, actually, I don't think that is the correct model for TCP.  There
was some consideration given to making TCP connections
process-to-process, but that was abandoned, I think because it seemed
to OS-dependent.  Instead, TCP connections end on "neutral territory"
between OS and network, the port space.  Each OS was then assumed to
have some way to couple its processes to ports.
