David Farber

networking

The organiser of CSNET, and one half of the 1981 agreement that let one network's traffic cross another's without anyone counting it.

CSNET existed because most computer science departments were not eligible for the ARPANET, and the arrangement he negotiated with Robert Kahn let CSNET traffic ride ARPANET infrastructure on a statistical, no-metered-settlements basis. That phrase is worth pausing on. Two organisations agreed to carry each other's traffic without measuring or billing it, because measuring would have cost more than it was worth - and that principle, invented as an accounting convenience between two American agencies, is how networks interconnect worldwide to this day. His CSNET software is also what Karlsruhe used to bring Germany online three years later.
