International Networking Working Group

The International Networking Working Group (INWG) was a group of prominent computer science researchers in the 1970s who studied and developed standards and protocols for computer networking.

History

The International Networking Working Group formed in October 1972 at the International Conference on Computer Communication held in Washington D.C. It was modelled on the ARPANET "Networking Working Group" created by Steve Crocker.[1]

Vint Cerf led the INWG and other active members included Alex McKenzie, Donald Davies, Roger Scantlebury, Louis Pouzin and Hubert Zimmermann.[2][3][4] These researchers represented the American ARPANET,[nb 1] the French CYCLADES project, and the British team working on the NPL network and subsequently the European Informatics Network.[2] Pouzin arranged affiliation with the IFIP, and INWG became IFIP working group 1 under Technical Committee 6 (Data Communication) with the title "International Packet Switching for Computer Sharing". This standing, although informal, enabled the group to provide technical input on packet networking to CCITT and ISO.[2][4][5][6]

Over three years, the group shared numerous 'notes' and held working groups to develop a protocol for internetworking called the International Transmission Protocol (ITP) and Transmission Control Program (TCP).[2] Louis Pouzin introduced the term catenet, the original term for an interconnected network, in October 1973,[2] published in a 1974 paper "A Proposal for Interconnecting Packet Switching Networks".[7] Cerf and Bob Kahn acknowledged several members of the group in their 1974 paper "A Protocol for Packet Network Intercommunication".[8]

The standard agreed by the group in 1975, "Proposal for an international end to end protocol", was written by Vint Cerf, Alex McKenzie, Roger Scantlebury, and Hubert Zimmermann.[9] It was presented to the CCIT in 1976 by Derek Barber, who became INWG chair earlier that year. It was not adopted by the CCIT or by the ARPANET. CCIT went on to adopt the X.25 standard in 1976, based on virtual circuits, and ARPANET ultimately developed the Internet protocol suite, based on the Internet Protocol as connectionless layer and the Transmission Control Protocol as a reliable connection-oriented service.[2][3][5][10][11][12]

Later international work led to the OSI model in 1984, of which many members of the INWG became advocates.[3] For a period in the late 1980s and early 1990s, engineers, organizations and nations became polarized over the issue of which standard, the OSI model or the Internet protocol suite would result in the best and most robust computer networks.[3][13][14]

The INWG continued to work on protocol design and formal specification until the 1990s when it disbanded as the Internet grew rapidly.[2]
