This paper describes the data communications activity at the National Physical Laboratory (NPL) during the period 1965-1975. The key feature of the NPL work was the development of the principle of packet switching, which was first proposed in a data communications context by D. W. Davies of the NPL in 1965. The report focuses on the construction of the NPL Data Communications Network, which first became operational in 1970. This network served both as a model for a possible U.K. national…

ARPA's motivations for developing the network and how ARPA and computer science researchers built the first wide-area packet-switching network are described.
The early history of packet switching in the UK [History of Communications]
The early activities by British engineers, led by Donald Davies of the National Physical Laboratory, the British Post Office, those of his own group at University College London, and others as well are recounted, and Peter Kirstein ties this work into ongoing activities in the United States at the time.
History of Communications
The article following, written by one of the lead engineers in the project, describes the development of AMPS, the first cellular telephone system in the United States, and the various engineering problems that had to be solved, step by step, sometimes quite painstakingly.

Where Wizards Stay Up Late is the story of the small group of researchers and engineers whose invention, daring in its day, became the foundation for the Internet.
Two Early Interactive Computer Network Experiments
Two early networking experiments joined a time-sharing computer at the System Development Corporation with systems at the Stanford Research Institute briefly in 1963 and at MIT Lincoln Laboratory in 1966-1967 and included experiments with the interactive use of remote programs.

The experimental data communication network being implemented at the National Physical Laboratory will act as a model of the 'local area' network assumed, but never analysed in detail, in the NPL proposal for a possible National Data Communication System.
Improvements in the design and performance of the ARPA network
In late 1968 the Advanced Research Projects Agency of the Department of Defense (ARPA) embarked on the implementation of a new type of computer network which would interconnect, via common-carrier

A general purpose store-and-forward data communication network is under development at NPL. The background to this work is described in companion papers(1)(2) which also detail the hardware
The terminal IMP for the ARPA computer network
A little over three years ago the Advanced Research Projects Agency began implementation of an entirely new venture in computer communications: a network that would allow for the interconnection, via common-carrier circuits, of dissimilar computers at widely separated, ARPA-sponsored research centers.
The design of a switching system to allow remote access to computer services by other computers and terminal devices
An experimental store-and-forward data communication network has been set up within the National Physical Laboratory site, intended to meet the requirements of computer to computer communications in a general manner, permitting resource-sharing applications and remote-access computer services to be developed in the Laboratory.

A digital communication network for computers giving rapid response at remote terminals
Those computer applications which involve rapid response to events at distant points create special problems in digital communication, and could increase more rapidly if better solutions existed to the communication problems.
The Control of Congestion in Packet-Switching Networks

A method of controlling congestion is proposed in which there is a finite number of packet carriers in the whole network, and this so-called "isarithmic" method of congestion control supplements and does not replace end-to-end flow control.
On Distributed Communications Networks
Simulation results are shown to indicate that highly efficient routing can be performed by local control without the necessity for any central, and therefore vulnerable, control point, as in a centralized system.
