Those computer applications which involve rapid response to events at distant points create special problems in digital communication. Such applications are increasing in number, and could increase more rapidly if better solutions existed to the communication problems. The present-day methods for communication of data in rapid-response systems employ 'private wires' for the transmission paths or, where the available data rate and reliability is sufficient, employ voice channels from the… 

Procedures and standards for inter-computer communications

In recent years there has been considerable discussion on computer communication networks, information service systems and the computer utility, pointing to the widening need for reliable computer-to-computer communications.

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.

The interface message processor for the ARPA computer network

The ARPA Network will initially interconnect many dissimilar computers at ten ARPA-supported research centers with 50-kilobit common-carrier circuits, but the network may be extended to include many other locations and circuits of higher bandwidth.

A model for the local area of a data communication network objectives and hardware organization

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.

Real time computer communications and the public interest

As the computer becomes more dependent upon communications services, so too does the data processing industry become more subject to the structure and practices of an industry that has now become a principal supplier of one of its key inputs of raw material.

Data Communications at the National Physical Laboratory (1965-1975)

The report focuses on the construction of the NPL Data Communications Network, which first became operational in 1970 and served both as a model for a possible U.K. national network and as a practical local area network (LAN) for the N PL site.

The evolution of packet switching

The history and trends of packet switching are examined in detail in order to better understand both the past and future evolution of this fast moving technology.

Packet switching

Packet switching is a term used to describe the internal operations of a particular type of data communications network that usually has a fixed topology and uses software to route information in a

The Arpanet and computer networks

The revolution in communications started with an experiment in computer networking, the ARPANET, and grew into a communications revolution called packet switching, where virtually all the world is linked by packet switched communications service so that any terminal can access almost any computer in the world.

The evolving art of packet switching

The picture emerges of well laid foundations and the prospect of rapid expansion in public packet-switched networks throughout the world, and the development of large switches, such as those being developed at BTRL, will play an important part in this.



Trends in digital communication by wire

The most fruitful approach to an examination of digital communication is to begin by studying PCM telephony and then to see how other services can be coordinated with it.

An experimental 224 mb/s digital repeatered line

An experimental digital repeatered line has been developed which transmits information at a rate of 224 Mb/s as part of an experimental highspeed digital transmission system. The PCM terminals and

Electrical Communication

THIS book tells the story of electrical communication, and shows how the entire science has been built up on a few fundamental facts. The first chapter tells the story of electricity and magnetism,
