The Advanced Research Projects Agency Network (ARPANET) was an early packet switching network and the first network to implement the protocol suite TCP/IP. Both technologies became the technical foundation of the Internet. ARPANET was initially funded by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense. Packet switching was based on concepts and designs by Americans Leonard Kleinrock and Paul Baran, British scientist Donald Davies and Lawrence Roberts of the Lincoln Laboratory. The TCP/IP communications protocols were developed for ARPANET by computer scientists Robert Kahn and Vint Cerf, and incorporated concepts by Louis Pouzin for the French CYCLADES project. (Wikipedia)
