Bolt Beranek and Newman Inc. ( BBN , also BBN Technologies ) is an American company that was founded in 1948 for the planning of acoustics and contributed significantly to the development of information technology.
BBN was founded by Richard Bolt and Leo Beranek , who were professors at the Massachusetts Institute of Technology and after a year their associate Robert Newman involved. The reason for the partnership was Bolt's overload with his assignment to plan the acoustics for the General Assembly of the United Nations . In the 1990s, the company changed its name to the abbreviation BBN, which its subsidiaries already had in the name.
In 1963 the Association for Computing Machinery published a text by Bolt Beranek and Newman. It describes the experimental operation of a remote computer by dialing a telephone and its spoken feedback. Such investigations into acoustics as a means of basic communication resulted in the competence of BBN in the creation of the first computer networks , the feasibility of which had to be proven by means of existing analog telephone networks.
In 1969, BBN realized the Interface Message Processor , which not only enabled the first computer network, but also the later Internet usability with a wide variety of devices. The early analysis of a denial of service from 1980 comes from Bolt Beranek and Newman.
In 1962 BBN became a founding partner of the engineering company Müller-BBN GmbH based in Munich . The five shareholders included Leo Beranek , who represented BBN, the acousticians Lothar Cremer , Manfred Heckl , Ludwig Schreiber and Helmut A. Müller . In 1972 BBN sold its shares to Leo Beranek and former employees of Müller-BBN . The company name was changed to Müller-BBM .
In the mid-1980s, the group included not only the subsidiary BBN Communications in the United States, but also, for example, BBN Communications UK in Great Britain and BBN Computer in Hong Kong . At the same time, for example, BBN repeatedly examined the effects of industrial noise on whales .
BBN Technologies has been a subsidiary of the US defense and technology group Raytheon since 2009 .
