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.[1][2][3][4][5]
Packet switching was based on concepts and designs by AmericansLeonard Kleinrock and Paul Baran, British scientist Donald Davies[6][7]and Lawrence Roberts of the Lincoln Laboratory.[8] The TCP/IPcommunications protocols were developed for ARPANET by computer scientists Robert Kahn and Vint Cerf, and incorporated concepts byLouis Pouzin for the French CYCLADES project.
