Initially referred to as the ''DOD Internet Architecture Model'', the Internet protocol suite has its roots in research and development sponsored by the Defense Advanced Research Projects Agency ([[DARPA]]) in the late 1960s.<ref name="Cerf DoD">{{cite journal|title=The DoD Internet Architecture Model|first1=Vinton G.|last1=Cerf|first2=Edward|last2=Cain|name-list-style=amp|journal=Computer Networks|volume=7|issue=5|date=October 1983|publisher=North-Holland|doi=10.1016/0376-5075(83)90042-9|pages=307–318}}</ref> After DARPA ini0hinitiated the pioneering [[ARPANET]] in 1969, [[Steve Crocker]] established a "Networking Working Group" which developed a host-host protocol, the [[Network Control Program (ARPANET)|Network Control Program]] (NCP).{{Ref RFC|1000}} In the early 1970s, DARPA started work on several other data transmission technologies, including mobile packet radio, packet satellite service, local area networks, and other data networks in the public and private domains. In 1972, [[Bob Kahn]] joined the DARPA [[Information Processing Technology Office]], where he worked on both satellite packet networks and ground-based radio packet networks, and recognized the value of being able to communicate across both. In the spring of 1973, [[Vinton Cerf]] joined Kahn with the goal of designing the next protocol generation for the ARPANET to enable [[internetworking]].<ref>{{Cite book |last1=Hafner |first1=Katie |url=http://archive.org/details/wherewizardsstay00haf_vgj |title=Where wizards stay up late : the origins of the Internet |last2=Lyon |first2=Matthew |date=1996 |publisher=New York : Simon & Schuster |others=Internet Archive |isbn=978-0-684-81201-4 |page=263}}</ref><ref name=":0">{{cite book |last1=Russell |first1=Andrew L. |url=https://books.google.com/books?id=jqroAgAAQBAJ&pg=PA196 |title=Open standards and the digital age: history, ideology, and networks |date=2014 |publisher=Cambridge Univ Press |isbn=978-1107039193 |___location=New York |page=196 |access-date=December 20, 2022 |archive-date=December 28, 2022 |archive-url=https://web.archive.org/web/20221228072845/https://books.google.com/books?id=jqroAgAAQBAJ&pg=PA196 |url-status=live }}</ref> They drew on the experience from the ARPANET research community, the [[International Network Working Group]], which Cerf chaired, and researchers at [[Xerox PARC]].<ref name="ZVVpe">{{Cite book|last=Abbate|first=Janet|author-link=Janet Abbate|url=https://books.google.com/books?id=E2BdY6WQo4AC&pg=PA123|title=Inventing the Internet|date=2000|publisher=MIT Press|isbn=978-0-262-51115-5|pages=123–4|language=en|access-date=May 15, 2020|archive-date=January 17, 2023|archive-url=https://web.archive.org/web/20230117175132/https://books.google.com/books?id=E2BdY6WQo4AC&pg=PA123|url-status=live}}</ref><ref>{{Citation |last=Taylor |first=Bob |title=Oral History of Robert (Bob) W.

By the summer of 1973, Kahn and Cerf had worked out a fundamental reformulation, in which the differences between local network protocols were hidden by using a common [[internetwork protocol]], and, instead of the network being responsible for reliability, as in the existing ARPANET protocols, this function was delegated to the hosts. Cerf credits [[Louis Pouzin]] and [[Hubert Zimmermann]], designers of the [[CYCLADES]] network, with important influences on this design.<ref name="YSZAX">{{Cite journal|last1=Cerf|first1=V.|last2=Kahn|first2=R.|date=1974|title=A Protocol for Packet Network Intercommunication|url=https://www.cs.princeton.edu/courses/archive/fall06/cos561/papers/cerf74.pdf|journal=IEEE Transactions on Communications|volume=22|issue=5|pages=637–648|doi=10.1109/TCOM.1974.1092259|issn=1558-0857|quote=The authors wish to thank a number of colleagues for helpful comments during early discussions of international network protocols, especially R.
