Over the past decade data communications has been revolutionized by a radically new technology called packet switching. In 1968 virtually all interactive data communication networks were circuit switched, the same as the telephone network. Circuit switching networks preallocate transmission bandwidth for an entire call or session. However, since interactive data traffic occurs in short bursts 90 percent or more of this bandwidth is wasted. Thus, as digital electronics became inexpensive enough… Expand
Packet switching and the communication networks of the eighties and beyond
TLDR
The principles, economics, benefits and prospects of employing the packet switching principles in the transmission of voice and the availability of voice packet networks have profound implications in providing cost-effective access to emerging voice-based computerised information services. Expand
Commercialization of packet switching (1975-1985): A Canadian perspective [History of Communications]
The following article provides a fast-moving, exciting account of the early days of commercial packet switching in the 1970s, focusing on X.25 and, in particular, on Datapac, the X.25-based CanadianExpand
Circuit versus Packet Switching
TLDR
This volume discusses the foundation for the Integrated Services Digital Network, which would handle all voice and data in a single network, with a unified switching and transmission approach, to reduce costs. Expand
Circuit switching in the internet
TLDR
This thesis argues that the use of circuit switching in the core of the network, in either electronic or optical form, would greatly benefit, and proposes two evolutionary ways of integrating circuit and packet switching, so that circuits are automatically controlled by the traffic carried by IP.

A packet/circuit switch
TLDR
A method of fault detection and isolation that will limit the impact of a failure on a serial memory to an arbitrarily small group of connected lines is indicated, and an index for measuring failure impact is defined to derive most-favorable fault-isolating partitions. Expand
The history of telenet and the commercialization of packet switching in the U.S.
TLDR
This article, the fifth in a series on the history of packet switching, provides an account of the early days of commercial packet switching services in the United States, written by key figures in these developments. Expand
Hot potatoes and postmen: how packet switching became ARPANET’s greatest legacy
TLDR
Paul Baran had a much more substantial influence on the decision to use packet switching for ARPANET than most retellings of Internet history portray, and Donald Davies’ role in the adoption of packet switching as a dominant principle for digital communication may have been less impactful. Expand
Communication Switching Centres
TLDR
This chapter discusses communication switching centers, which are located at the hub of the communication network, in a configuration known as a star network. Expand
An Expandable Architecture for a Conferencing Digital Communications Switch
TLDR
This paper architecturally describes the switching portion of a digital communications system that is dedicated to conferencing, and concludes that if the provision for dyna~ic reconfiguration is added, the switch fits the criteria for being a distributed processing system. Expand
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 aExpand

The terminal IMP for the ARPA computer network
TLDR
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. Expand
A digital communication network for computers giving rapid response at remote terminals
TLDR
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. Expand
Computer report III: Data by the packet: Because computing costs are now so low, an unusual new concept of data communications is feasible
TLDR
The ARPA computer network is discussed and an unusual new concept of data communications called packet switching, which uses computers to correct transmission errors, to provide high reliability through alternate routing, and to allocate communication bandwidth dynamically on a demand basis rather than as a preassigned bandwidth. Expand
Throughput in the ARPANET - Protocols and Measurement
TLDR
The ARPANET throughput is respectably high and the sources of throughput degradation at longer distances are identified, a major cause being due to a poor movement of critical limiting resources around in the network. Expand
The interface message processor for the ARPA computer network
TLDR
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. Expand
