HiPPI

 High-Performance Parallel Interface): As the guys a CERN say, “it’s not just for supercomputers anymore.” Also known as GSN, or Gigabyte System network, HiPPI is one of the original high-speed LAN technologies and interoperates with Ethernet, fibre channel and ATM. It is an ANSI standard for a full-duplex, low-latency, point-to-point interconnect providing 100 to 200 Mbytes/second over a 50 twisted-pair copper PHY with a maximum length of 25 meters. A serial version uses a glass-fiber PHY at the same speed; future versions will scale up to 6.4 Gbits/second.
