17 Facts About Packet switching

In telecommunications, packet switching is a method of grouping data into packets that are transmitted over a digital network.

Packet switching is the primary basis for data communications in computer networks worldwide.

Packet switching's ideas contradicted then-established principles of pre-allocation of network bandwidth, exemplified by the development of telecommunications in the Bell System.

Davies is credited with coining the modern term packet switching and inspiring numerous packet switching networks in the decade following, including the incorporation of the concept into the design of the ARPANET in the United States.

Packet switching allows delivery of variable bit rate data streams, realized as sequences of packets, over a computer network which allocates transmission resources as needed using statistical multiplexing or dynamic bandwidth allocation techniques.
