Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by the American National Standards Institute and International Telecommunication Union Telecommunication Standardization Sector for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and real-time, low-latency content such as telephony (voice) and video. ATM provides functionality that uses features of circuit switching and packet switching networks by using asynchronous time-division multiplexing. ATM was seen in the 1990s as a competitor to Ethernet and networks carrying IP traffic as, unlike Ethernet, it was faster and designed with quality-of-service in mind, but it fell out of favor once Ethernet reached speeds of 1 gigabits per second.
Telefonaktiebolaget LM Ericsson, commonly known as Ericsson, is a Swedish multinational networking and telecommunications company headquartered in Stockholm, Sweden. The company sells infrastructure, software, and services in information and communications technology for telecommunications service providers and enterprises, including, among others, 3G, 4G, and 5G equipment, and Internet Protocol (IP) and optical transport systems. The company employs around 100,000 people and operates in more than 180 countries. Ericsson has over 57,000 granted patents.
3Com Corporation was an American digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Bill Krause joined as President in 1981. 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.
The General Electric Company (GEC) was a major British industrial conglomerate involved in consumer and defence electronics, communications, and engineering.
The Plessey Company plc was a British electronics, defence and telecommunications company. It originated in 1917, growing and diversifying into electronics. It expanded after World War II by acquisition of companies and formed overseas companies. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index. In 1989, it was taken over by a consortium formed by GEC and Siemens which split the assets of the Plessey group.
PMC-Sierra was a global fabless semiconductor company with offices worldwide that developed and sold semiconductor devices into the storage, communications, optical networking, printing, and embedded computing marketplaces.
In computer networking and telecommunications, a pseudowire is an emulation of a point-to-point connection over a packet-switched network (PSN).
A pseudowire in networking is a way to emulate a physical wire across a packet-switched network. Essentially, it lets two endpoints feel as if they’re directly connected by a traditional wire, even though the data is actually traveling over a more complex network, such as an IP or MPLS network.
Ferranti or Ferranti International PLC was a UK electrical engineering and equipment firm that operated for over a century from 1885 until it went bankrupt in 1993. The company was once a constituent of the FTSE 100 Index.
The Marconi Company was a British telecommunications and engineering company founded by Italian inventor Guglielmo Marconi in 1897 which was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies.
Marconi Communications, the former telecommunications arm of Britain's General Electric Company plc (GEC), was founded in August 1998 through the amalgamation of GEC Plessey Telecommunications (GPT) with other GEC subsidiaries: Marconi SpA, GEC Hong Kong, and ATC South Africa.
GEC Plessey Telecommunications (GPT) was a British manufacturer of telecommunications equipment, notably the System X telephone exchange. The company was founded in 1988 as a joint venture between GEC and the British electronics, defence and telecommunications company Plessey. The next year, after a joint holding company of GEC and the German conglomerate Siemens acquired Plessey, GPT was converted into a 60/40 GEC/Siemens joint venture. The GPT name ceased to be used in the mid-1990s, and in 1998 the company was amalgamated into Siemens Communications.
Bay Networks, Inc., was a network hardware vendor formed through the merger of Santa Clara, California, based SynOptics Communications and Billerica, Massachusetts based Wellfleet Communications on July 6, 1994. SynOptics was an important early innovator of Ethernet products, having developed a pre-standard twisted pair 10 Mbit/s Ethernet product and a modular Ethernet hub product that dominated the enterprise networking market. Wellfleet was an important competitor to Cisco Systems in the router market, ultimately commanding up to a 20% market share of the network router business worldwide. The combined company was renamed Bay Networks, as SynOptics was based in the San Francisco Bay Area and Wellfleet in Greater Boston, nearby to Massachusetts Bay.
Tracor, Inc. was a major North American defense electronics contractor which was acquired by Marconi Electronic Systems (MES), a subsidiary of General Electric Company plc, in 1998. Following the purchase of MES by British Aerospace in November 1999 to form BAE Systems, Tracor became BAE Systems Integrated Defense Solutions. Following a 2005 reorganisation, the company became BAE Systems Sensor Integration, part of Electronics and Integrated Solutions.
Telent Technology Services Limited is a British radio, telecommunications, and digital infrastructure systems installation and services provision company. The name is used from 2006 for those parts of the United Kingdom and German services businesses of Marconi Corporation which had not been acquired by Ericsson. Companies with Marconi in their name can trace their ultimate origins, through mergers and takeovers, to The Marconi Company Ltd, founded by Guglielmo Marconi in 1897 as The Wireless Telegraph & Signal Company.
In computer networking, an edge device is a device that provides an entry point into enterprise or service provider core networks. Examples include routers, routing switches, integrated access devices (IADs), multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices. Edge devices also provide connections into carrier and service provider networks. An edge device that connects a local area network to a high speed switch or backbone may be called an edge concentrator.
Drew D. Perkins is a serial entrepreneur and is co-founder and CEO of Mojo Vision, a company developing Mojo Lens, the first true smart contact lens.
Madge Networks NV was a networking technology company founded by Robert Madge, and is best known for its work with Token Ring. It was a global leader and pioneer of high-speed networking solutions in the mid-1990s, and also made significant contributions to technologies such as Asynchronous Transfer Mode (ATM) and Ethernet.
Ipsilon Networks, Inc., was a computer networking company which specialised in IP switching during the 1990s.
Berkeley Networks was a leading startup company that built intelligent switches targeted for the enterprise computer networking market segment.
Circuit emulation service (CES) is a telecommunication technology used to send information over asynchronous data networks like ATM, Ethernet or MPLS, so that it is received error-free with constant delay, similar to a leased line.
