Ipsilon Networks

Ipsilon Networks was a computer networking company which specialised in IP switching during the 1990s.

The first product called the IP Switch ATM 1600 was announced in March 1996 for US$46,000.[1] Its switch used Asynchronous Transfer Mode (ATM) hardware combined with Internet Protocol routing.[2] The company had a role in the development of the Multiprotocol Label Switching (MPLS) network protocol.[3] The company published early proposals[4] related to label switching,[5] but did not manage to achieve the market share hoped for and was purchased for $120 million by Nokia in December 1997.[6] The president at the time was Brian NeSmith, and it was located in Sunnyvale, California.[6]
