Extreme Networks, founded in 1996, is a publicly listed company that designs, builds, and installs Ethernet computer network products for enterprise and carrier grade (metro) networks. Extreme Networks is based in Santa Clara, California. It markets high performance networks with the large scale and speed of 10-gigabit Ethernet, 40 Gigabit and 100 Gigabit Ethernet.


Early investors included Norwest Venture Partners, AVI Capital Management, Trinity Ventures, and Kleiner Perkins Caufield & Byers.[1] Gordon Stitt was a co-founder and served as chief executive officer until August 2006, when he retired and became chairman of the board of directors. In October 1996 Extreme Networks acquired Mammoth Technology. In September 1997 Extreme Networks aided in providing the first multi-vendor Gigabit Ethernet backbone at the Networld+Interop trade show. The company's first product was the Summit1 Gigabit Ethernet switch, a 6 Port Ethernet Layer 3 switching device featuring dual gigabit interface converter (GBIC) 1000BASE-SX interfaces. This product shipped in 1997 and won the "Best of Show" award at Networld+Interop. The Summit1 was also named the "Best of the Best Grand Winner" for the event. Extreme Networks won Best of Show awards at Networld+Interop five consecutive years, 1997 through 2001 with its Summit PX1 application switch, a Layer 4-7 device.

Extreme Networks introduced its first modular switching products, including the BlackDiamond 6800 and Alpine 3800 switches, in 1999. The initial public offering in April 1999, was listed on the NASDAQ stock exchange as ticker "EXTR."[1] Extreme Networks acquired Optranet in February 2001 and Webstacks in March 2001. Extreme had been investors in both companies, which were purchased for about $73 million and $74 million respectively.[2] Extreme Networks announced its first 10-gigabit Ethernet product in 2002, available with its BlackDiamond 6800 switch.

Extreme's BlackDiamond 10808 switch was named technology product of the year by InfoWorld in January 2004. Extreme Networks announced wireless LAN products marketed for "converged data and voice" in June 2005. Mark Canepa became chief executive in August 2006. In September 2008 Extreme Networks announced its BlackDiamond 20808 Ethernet switch.[3] In February 2009 Extreme announced its Summit X650 data center switch using the term "top-of-rack".[4] In March 2009 Extreme announced a ReachNXT enterprise port extender product.[5]

Extreme Networks first used VxWorks as its operating system (OS) for its switching products, calling its software ExtremeWare.[6][7] The ExtremeXOS software OS began in 2003 with its BlackDiamond 10808 switch, featuring a Linux abstraction layer. ExtremeXOS was later expanded with its Summit line of fixed switches and the BlackDiamond 8800 family of modular products.

Extreme Networks' high capacity switch is the BlackDiamond X8, supporting 2.56 Terabits per line card, and is purpose built for data center and enterprise networks.

On September 12, 2013, it was announced that Enterasys would be purchased by Extreme networks for a stock transaction amounting to $180,000,000.[8]
