No, the tuple includes source ip and port as well.

Ah. Thanks guys.

I'll fill in some more things. They didn't have the bloat back then that we have these days, like the crazy deep call stacks you see in both object-oriented and functional programming. CICS programs were frequently written in assembler, sometimes COBOL and PL/I. Mainframe compilers from the early 1970s were much more advanced in many ways than the Unix/C technology described in the Dragon Book. The mainframe did I/O…
