The ARPANET was at first financed by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense. The bundle exchanging philosophy utilized in the ARPANET depended on ideas and outlines by Leonard Kleinrock and Paul Baran, British researcher Donald Davies, and Lawrence Roberts. The TCP/IP interchanges conventions were produced for the ARPANET by PC researchers Robert Kahn and Vint Cerf, and joined ideas from the French CYCLADES venture coordinated by Louis Pouzin.
