HIPPI is a high-performance interface originally designed to interconnect high-end workstations, supercomputers, and peripheral devices in a local network configuration. As the name implies, it is a parallel interface, as compared to the serial interfaces such as those described under "Serial Communication and Interfaces." It grew out of work done at the LANL (Los Alamos National Laboratory). HIPPI is ANSI standard X3T9.3 and it is also known as ANSI T11.1.
