PARC is a research and development company in Palo Alto, California, with a distinguished reputation for its contributions to information technology and hardware systems.
Xerox Corporation is an American global corporation that sells print and digital document products and services in more than 160 countries. Xerox is headquartered in Norwalk, Connecticut, though its largest population of employees is based around Rochester, New York, the area in which the company was founded. The company purchased Affiliated Computer Services for $6.4 billion in early 2010. As a large developed company, it is consistently placed in the list of Fortune 500 companies.
3Com Corporation was a digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Metcalfe explained the name 3Com was a contraction of "Computer Communication Compatibility", with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers.
Xerox Network Systems (XNS) is a computer networking protocol suite developed by Xerox within the Xerox Network Systems Architecture. It provided general purpose network communications, internetwork routing and packet delivery, and higher level functions such as a reliable stream, and remote procedure calls. XNS predated and influenced the development of the Open Systems Interconnection (OSI) networking model, and was very influential in local area networking designs during the 1980s. It had little impact on TCP/IP, however, which was designed earlier.
Apollo Computer Inc., founded 1980 in Chelmsford, Massachusetts by William Poduska and others, developed and produced Apollo/Domain workstations in the 1980s. Along with Symbolics and Sun Microsystems, Apollo was one of the first vendors of graphical workstations in the 1980s. Like computer companies at the time and unlike manufacturers of IBM PC compatibles, Apollo produced much of its own hardware and software.
LattisNet was a family of computer networking hardware and software products built and sold by SynOptics Communications during the 1980s. Examples were the 1000, 2500 and 3000 series of LattisHub network hubs. LattisNet was the first implementation of 10 Megabits per second local area networking over unshielded twisted pair wiring in a star topology.
Wellfleet Communications was an Internet router company founded in 1986 by Paul Severino, Bill Seifert, Steven Willis and David Rowe based in Bedford, Massachusetts, and later Billerica, Massachusetts. In an attempt to more effectively compete with Cisco Systems, its chief rival, it merged in October, 1994 with SynOptics Communications of Santa Clara, California to form Bay Networks in a deal worth US$ 2.7B. Bay Networks would in turn be acquired by Nortel in June, 1998 for US$ 9.1B.
American Photonics, Inc. (API) was a very early developer of local area network technologies in the 1980s, based first in Brewster, New York, moving later to Brookfield Center, CT.
Chipcom was an early pioneering company in the Ethernet hub industry. Their products allowed Local Networks to be aggregated in a single place instead of being distributed across the length of a single coaxial cable. They competed with now-gone companies such as Cabletron Systems, SynOptics, Ungermann-Bass, David Systems, Digital Equipment Corporation, and American Photonics, all of which were early entrants in the "LAN Hub" industry. Chipcom also was involved in Token Ring, FDDI, and Asynchronous Transfer Mode (ATM).
David Reeves Boggs is an electrical and radio engineer from the United States who developed early prototypes of Internet protocols, file servers, gateways, network interface cards and, along with Robert Metcalfe and others, co-invented Ethernet, the most popular family of technologies for local area computer networks.
The Nortel Discovery Protocol (NDP) is a Data Link Layer network protocol for discovery of Nortel networking devices and certain products from Avaya and Ciena. The device and topology information may be graphically displayed network management software.
Abbey Silverstone is a very early member of the computer development family with a 50-year career in the computer industry that included time as Co-founder and VP of operations of Silicon Graphics (SGI).
John F. Shoch is an American computer scientist and venture capitalist who made significant contributions to the development of computer networking while at Xerox PARC, in particular to the development of the PARC Universal Protocol (PUP), an important predecessor of TCP/IP.
Ixia is a public company operating in around 25 countries. Ixia is headquartered in Calabasas, California and has approximately 1750 employees. It has been acquired by Keysight Technologies Inc. in 2017.
Mellanox Technologies Ltd. is an Israeli multinational supplier of computer networking products using InfiniBand and Ethernet technology. Mellanox offers adapters, switches, software, cables and silicon for markets including high-performance computing, company data centers, cloud computing, computer data storage and financial services.
