In 1972, he joined Xerox PARC to develop these ideas, and after pairing up with David Boggs, the two had early 3 Mbit/s versions of Ethernet working in 1973.
In 1972, he joined Xerox PARC to develop these ideas, and after pairing up with David Boggs, the two had early 3 Mbit/s versions of Ethernet working in 1973.
They then went on to build up a networking protocol known as PARC Universal Packet (PuP), with the entire system ready for build-out by late 1974. At this point, Xerox management did nothing with it, even after being approached by prospective customers.
Increasingly upset by management's lack of interest, Metcalfe left Xerox in 1975, but he was lured back again the next year.
Further development followed, resulting in the seminal Xerox Network Systems (XNS) protocol, which was completed by 1978.
The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others.
Once again, Metcalfe found that management was unwilling to actually do anything with the product, and he threatened to leave and in 1979 he left the company. ===Founding and early days (1979–1996)=== Metcalfe subsequently co-founded 3Com in 1979.

3Com began making Ethernet adapter cards for many early 1980s computer systems, including the DEC LSI-11, DEC VAX-11 and the IBM PC.
Voice platforms included VCX and NBX. Local area network interface cards IP Video Surveillance and Network Storage (marketed in China, South Africa, South America and other key markets) Consumer USB webcams and associated software (3Com HomeConnect) The 3Com Laser Library ===Acquisitions=== 3Com came close to merging with computer maker Convergent Technologies, abandoning the pact just two days before a vote was scheduled in March 1986.
Robotics was also spun out again as a separate company at this time. ===2001 and beyond=== In January 2001, Claflin became chief executive officer, replacing Eric Benhamou, CEO from 1990 to 2000.
That agreement ended in 2002. ===1997–2000=== In 1997, 3Com merged with USRobotics (USR), a maker of dial-up modems, and owner of Palm, Inc..
3Com continued the development of the Total Control line until it was eventually spun off as a part of Commworks, which was then acquired by UTStarcom. In August 1998, Bruce Claflin was named chief operating officer.
It led to follow on products that became core to CommWorks now UTStarcom offerings including the 2.5 and 3G packet data gateway products known as PDSN and Home Agents. CommWorks/3Com co-developed an H.323-based softswitch with AT&T in 1998 for use in a "transparent trunking" application for AT&T's residential long-distance customers.
Later, it formed a joint venture with Broadcom, where Broadcom would develop the main integrated circuit component and the NIC would be 3Com branded. In 1999, 3Com acquired NBX, a Boston company with an Ethernet-based phone system for small and medium-sized businesses.
As one of the first companies to deliver a complete networked phone system, and increased its distribution channel with larger telephony partners such as Southwestern Bell and Metropark Communications, 3Com helped make VoIP into a safe and practical technology with wide adoption. 3Com then tried to move into the smart consumer appliances business and in June 2000, 3Com acquired internet radio startup Kerbango for $80 million.
It scrapped the Audrey and Kerbango products less than a year later. In March 2000, in a highly public and criticized move, 3Com exited the high-end core routers and switch market to focus on other areas of the business.
The CoreBuilder Ethernet and ATM LAN switches, PathBuilder and NetBuilder WAN Routers were all discontinued June 2000.
3Com focused its efforts from 2000 to 2003 on building up the HomeConnect, OfficeConnect, SuperStack, NBX and Total Control product lines.
Due to this perceived exit from the Enterprise market, 3Com would never gain momentum with large customers or carriers again. In July 2000, 3Com spun off Palm as an independent company.
Robotics was also spun out again as a separate company at this time. ===2001 and beyond=== In January 2001, Claflin became chief executive officer, replacing Eric Benhamou, CEO from 1990 to 2000.
When it reached the destination, it was passed to the egress LEC's CLASS 5 switch as an untariffed data call. CommWorks modified the gateway and softswitch software to support SIP for MCI/WorldCom's hosted business offering in 2000. Although 3Com sold CommWorks to UTStarcom, they retained intellectual property rights to the softswitch technology.

That agreement ended in 2002. ===1997–2000=== In 1997, 3Com merged with USRobotics (USR), a maker of dial-up modems, and owner of Palm, Inc..
3Com focused its efforts from 2000 to 2003 on building up the HomeConnect, OfficeConnect, SuperStack, NBX and Total Control product lines.
The company went from employing more than 12,000 employees to fewer than 2,000. In May 2003, the company moved its Silicon Valley Santa Clara headquarters to Marlborough, Massachusetts.
It also formed a venture called H3C with Huawei, whereby 3Com would sell and rebrand products under the joint venture. In 2003, 3Com sold its CommWorks Corporation subsidiary to UTStarcom, Inc.
It was sold to UTStarcom of Alameda, California in 2003. CommWorks was formerly the Carrier Network Business unit of 3Com, comprising several acquired companies: U.S.
After modifying the software to enable enterprise PBX features, 3Com released this technology as VCX, the industry's first pure SIP PBX, in 2003. ==See also== 3Station Busy Override List of acquisitions by Hewlett-Packard ==References== Bibliography ==External links== HP Networking Official H3C Technologies Co.
CommWorks was based in Rolling Meadows, Illinois, and developed wireline telecommunications and wireless infrastructure technologies. In January 2006, Claflin announced he would be leaving the company.
In January 2006, R Scott Murray became CEO of 3Com and chairman of H3C Technology in China, the joint venture with Huawei Technologies.
Murray voluntarily resigned from the company in August 2006 over his concerns about the questionable business ethics of Huawei and potential cyber security risks posed by Huawei.
From its 2007 acquisition of 100 percent ownership of H3C Technologies Co., Limited (H3C) —initially a joint venture with China-based Huawei Technologies—3Com achieved a market presence in China, and a significant networking market share in Europe, Asia, and the Americas.
Edgar Masri returned to 3Com to head as president and CEO following Murray's departure. In September 2007, Bain Capital agreed to buy the company for $2.2 billion, with minority equity financing from Huawei Technologies.
government regulatory opposition and it fell through early in 2008, following concerns over Huawei's risk of conducting cyber security threats against the United States Government and its allies, Huawei's former dealings in Iran, and Huawei being operated by a former engineer in China's People's Liberation Army.
Edgar Masri left the company in April 2008, partially as a result of the failed Bain transaction. In April 2008, Robert Mao was named chief executive, and Ron Sege president and chief operating officer. In fiscal year 2008 ended May 30, 2008, 3Com had annual revenue of $1.3 billion and more than 6,000 employees in over 40 countries.
In September 2008, 3Com reported financial results for its fiscal 2009 first quarter, which ended August 29, 2008.
Revenue in the quarter was $342.7 million compared to revenue of $319.4 million in the corresponding period in fiscal 2008, a 7 percent increase.
Net income in the quarter was $79.8 million, compared with a net loss of $18.7 million in the first quarter of fiscal year 2008. The company reported that it had more than 2,700 engineers, with more than 1,400 United States patents and nearly 180 Chinese-issued patents, as well as more than 1050 pending Chinese applications.
In September 2008, 3Com reported financial results for its fiscal 2009 first quarter, which ended August 29, 2008.
It also reported pending applications for 35 separate inventions outside of China covering a wide range of networking technologies. ===Acquisition by HP=== On November 11, 2009, 3Com and Hewlett-Packard announced that Hewlett-Packard would acquire 3Com for $2.7 billion in cash.
3Com products were sold under the brands 3Com, H3C, and TippingPoint. On April 12, 2010, Hewlett-Packard completed the acquisition of 3Com, and it no longer exists as a separate entity.
On April 12, 2010, Hewlett-Packard completed its acquisition.

3Com's products, support, and technologies were eventually merged into HPE's Aruba Networks business unit following HP's acquisition of Aruba in 2015 and subsequent split into HPE later that same year. ==History== ===Xerox PARC (1972-1979)=== After reading an article on ALOHAnet, Robert Metcalfe became interested in computer networking.
