<P> In the early 1960s , American computer scientist Paul Baran developed the concept Distributed Adaptive Message Block Switching with the goal to provide a fault - tolerant , efficient routing method for telecommunication messages as part of a research program at the RAND Corporation , funded by the US Department of Defense . This concept contrasted and contradicted then - established principles of pre-allocation of network bandwidth , largely fortified by the development of telecommunications in the Bell System . The new concept found little resonance among network implementers until the independent work of British computer scientist Donald Davies at the National Physical Laboratory ( United Kingdom ) in 1965 . Davies is credited with coining the modern name packet switching and inspiring numerous packet switching networks in the decade following , including the incorporation of the concept in the early ARPANET in the United States . </P>
