As an initial matter, PRNET and SATNET created the possibility of multipath routing by employing broadcast technologies capable of simultaneously transmitting the same packet to multiple recipients instead of establishing a connection and transferring packets between two specific hosts.
Perhaps the most celebrated demonstration of how gateways could facilitate the interconnection of heterogeneous networks occurred in 1977, when a communication initiated by a truck connected to the PRNET in the San Francisco area was routed through the ARPANET to London, transmitted via SATNET from London to West Virginia, rerouted again through an ARPANET connection in Cambridge, Massachusetts, and delivered to the University of Southern California's Information Sciences Institute in Marina del Rey, California.
The PRNET benefited from the operational experience of a Hawaii-based packet radio network known as ALOHA.
