FORE Systems, Inc., was a computer network switching equipment company based in Pittsburgh, Pennsylvania. Founded in 1990 to supply Asynchronous Transfer Mode (ATM) cards for workstation computers, it soon branched out to become a major supplier in the ATM switch market and the extended those product lines to add Internet Protocol switching and other devices.

FORE was purchased by the British General Electric Company (GEC) in 1999,^[1] just before the dot-com bubble, which eventually drove GEC to reform the company as Marconi. Ericsson purchased most of Marconi in 2006.^[2]

History

Francois Bitz, Onat Menzilcioglu, Robert Sansom and Eric Cooper were researchers at Carnegie Mellon University who felt their 1989 project to supply a US Naval Research Laboratories Request for Development had commercial potential. They formed FORE, using the first letter of their first names, in 1990 in the Pittsburgh suburb of Warrendale, Pennsylvania. The company went public in May 1994.^[3]

FORE initially produced Asynchronous Transfer Mode (ATM) network interface cards for Sun Microsystems' SBus and DEC's TURBOchannel based computers in addition to ATM adapters for Silicon Graphics computers. FORE's first ATM switch – the ASX-100 – connected sixteen ATM ports each with a capacity of 155.52 Mbit/s. Later interface adapters for the follow-on ASX-200, ASX-1000, and ASX-4000 switches allowed connections up to 2.5 Gbit/s.

The company established a leading position in the market for ATM switching equipment. FORE created a memory-based ATM switch that captured a strong portion of the ATM market. Other technologies include Internet Protocol, Gigabit Ethernet and Firewall switching. FORE Systems also supported advanced dynamic routing protocols such as the ForeThought Private Network Network Interface (PNNI) and the ATM Forum's PNNI protocol.

FORE was acquired by London-based GEC^[3] (now Marconi Corporation plc) on 26 April 1999 to complement its Marconi Communications business and to increase its presence in North America, the world's largest telecoms market. This was near the peak of the dot-com bubble. The £2.8bn (US$4.5bn) ($8.4 billion today) price tag for FORE^[4] and the £1.3n spent on Reltec a month earlier took a heavy toll on Marconi following the burst of the bubble in 2000/2001.

In July 2001 Marconi plc suffered a 54% drop in its share price following suspension of trading of its shares, a profits warning and redundancies. The company survived following a relaunch as Marconi Corporation plc in a debt-for-equity swap whereby the firm's creditors received 99.5% of the new company's shares.

In 2006, Ericsson purchased most of Marconi, including the part that used to be FORE Systems. In 2008, Ericsson closed the Warrendale plant and sold off the corporate HQ.^[3]
