It is an ANSI standard since autumn 1998. It is based on parallel copper and parallel fibre optics connections. Network connections are made using switches and bridges allow connections to different technology networks such as HIPPI, Fibre Channel and Gigabit Ethernet. Together with GSN comes the Scheduled Transfer (ST) protocol, a protocol that bypasses the operating system and as such has a very low latency. Encapsulation of other network protocols is foreseen and makes ST extremely flexible. ST is also a vehicle for implementing non-proprietary, media independent Storage Area Networks. ST's small control messages and pre-arranged information transfers provide full-rate, flows controlled non-congesting data movements regardless of the specific network media. ST creates a uniform access method across the heterogeneous range of servers and networks. SAN's based on ST are scalable far beyond the possibilities of a single interconnect such as Fibre Channel. Due to its high throughput and its low latency, the combination of GSN and ST can also be an attractive solution for data acquisition in large HEP experiments. An S-Link connection to GSN should be easy to develop and can have a large fan-in. The workshop is organised in collaboration with the High Performance Networking Forum (HNF). Many of the speakers are members of HNF and worked on the specifications of the GSN and ST standards. For more information and last moment modifications contact A.
