Vendor lineage
3Com - Ethernet leaves the lab
Bob Metcalfe commercialized his own PARC invention; EtherLink wired the PC era, Palm rode along, and the story ended at HP in 2010.
3Com is the second half of the Ethernet story this section starts on the Xerox page: Metcalfe left PARC in 1979 to sell the network he had invented, and the EtherLink card put Ethernet inside the IBM PC itself. Computers, Communication, Compatibility - the three Coms - became the connectivity company of the LAN decade.
From the first PC Ethernet adapters through the US Robotics merger that brought Palm aboard, to the H3C venture in China and the 2010 HP acquisition - the profile below follows the wire out of the lab and into everything.
Founding stories
3Com
Bob Metcalfe invented Ethernet at Xerox PARC in 1973; in 1979 he left to sell it. 3Com - Computers, Communication, Compatibility - bet that the network Xerox would not commercialize could become a product for everyone, and the 1980 DIX standard (Metcalfe had persuaded DEC, Intel, and his old employer to publish it) made the bet safe. The 1982 EtherLink card put Ethernet on an ISA slot inside the IBM PC, and the LAN stopped being a laboratory concept. Where the Xerox page in this section tells the invention, this page tells the industry.
The timeline
- The DIX standard
Metcalfe's evangelism gets DEC, Intel, and Xerox to publish Ethernet as an open specification - the single act that let a startup build a market on a giant's invention.
- EtherLink
The first Ethernet adapter for the IBM PC with the transceiver on the card itself - thin coax, one slot, and the office LAN becomes something a business buys at retail.
- Bridge Communications
The merger with Bridge adds routers, terminal servers, and enterprise ambition; through the 1990s 3Com's adapters, hubs, and switches wire an enormous share of the world's desktops.
- US Robotics - and Palm
The ~$6.6 billion stock merger brings modems at their peak and, almost incidentally, Palm - whose Pilot becomes the defining handheld and, by its March 2000 IPO, briefly worth more than its parent.
Deal value ~$6.6B as widely reported at announcement.
- H3C: the China venture
After retreating from high-end enterprise in 2000, 3Com forms Huawei-3Com; it buys full ownership in November 2007, and a 2008 Bain-led buyout involving Huawei collapses over CFIUS national-security review - a preview of the decade to come.
- HP closes
April 12, 2010: HP completes the ~$2.7 billion acquisition, aiming H3C and 3Com's networking at Cisco; the brand dissolves into HP Networking, and its Chinese arm later anchors the H3C that Tsinghua Unigroup majority-owns.
Announced November 11, 2009; close per the deal record.
Flagship products and solutions
- EtherLink adaptersThe cards that put Ethernet in the PC - among the highest-volume networking products of their era.
- SuperStack and CoreBuilderThe stackable and enterprise switching lines of the 1990s LAN buildout.
- Palm (1997-2000)The handheld that arrived with US Robotics and briefly out-shone everything else in the house.
Key innovations
- Commercializing an open standard3Com proved the playbook this whole industry runs on: give the standard away, win the implementation - the founder sold the market on openness before selling it a single card.
- Ethernet on the desktopOn-board transceivers and PC-slot economics turned Ethernet from facility infrastructure into a per-desk commodity.
Main markets
3Com's lineage persists inside HPE's networking portfolio and in H3C's China market; its true monument is that the port it commercialized is simply called Ethernet everywhere.
Analyst standing
- For the adapter and SMB-networking categories of the late 80s and 90s, 3Com was the volume leader the evaluations assumed - the counterweight to Cisco below the enterprise core until the categories merged over it.
