The High Performance Networking Forum (HNF) was organized to promote the Gigabyte System Network®(GSN®- a trademark of the HNF) and High Performance Parallel Interface (HIPPI) networking. This industry-wide effort is committed to providing customers with open and interoperable GSN and HIPPI solutions.
The HNF is made up of organizations from around the world including platform vendors Compaq Computer Corporation, Silicon Graphics, IBM, Cray, plus CERN, Los Alamos National Laboratories, the European Centre for Medium Range Weather Forecasting, and others.

Gigabyte System Network®, or GSN®, is the highest bandwidth and lowest latency interconnect standard, providing full duplex dual 6400 megabit (800 megabyte) per second of error-free, flow controlled data. The technology is ideal wherever organizations require timely movement of large amounts of information including scientific and technical computing, HDTV, data mining, transaction processing, video and film archiving, and storage management. The proposed ANSI standard provides for interoperability with Ethernet, Fibre Channel, ATM, HIPPI-800 and other standards.
