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 circuits, a number of dissimilar computers at widely separated, ARPA-sponsored research centers. The primary purpose of this interconnection was resource sharing, whereby persons and programs at one research center might access data and interactively use programs that exist and run in other computers… 
Reliability issues in the ARPA network
Since the inception of the ARPA Network1 in 1969, this role has provided a unique opportunity for study of the problems of network reliability and the effects of attempted improvements, particularly in the context of rapid network growth.
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.
Influence on Packet Node Behavior of the Internode Protocol
Basic node-to-node protocol of a packet-switched network based on the multiplexing of the link into N logical channels is first described and some questions are raised in connection with adaptive-routing algorithms.

The justifications for a corporate computer network are discussed, a proposed stage by stage development is outlined, and solutions for several of the problems inherent in such a network are proposed.
Research areas in computer communication
Perhaps the most sophisticated form of Computer Communications may be found in data communication networks, and a fair amount of sophistication is usually required in the allocation of resources in order to realize the large savings from resource sharing.
Throughput in the ARPANET - Protocols and Measurement
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.
Computer Communication Networks: Approaches, Objectives, and Performance Considerations
A hypothesis is advanced that the "packet-switched" networks provide the most appropriate technology for supporting multimodal traffic between hosts and when several hosts and the communications subnetwork are under the control of a single administrative organization.
The Birth of Link-State Routing
My PhD dissertation for Harvard on routing was completed while working full-time at BBN, and described the problem, analyzed and compared many routing algorithms, and pointed out topics for further work, such as hierarchical routing for networks of networks.
Interconnection of Computer Networks
Techniques to implement internet addressing, routing, error recovery, and other necessary communication services on top of local network facilities appear feasible without demanding large changes to individual nets.

A new computer-communication partnership, and a burgeoning computer network technology, have moved a myriad of such activities from possible to convenient, and now such activities can and will really occur on a wide scale in many areas of application.


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.
HOST-HOST communication protocol in the ARPA network
The Advanced Research Projects Agency (ARPA) Computer Network (hereafter referred to as the "ARPA network") is one of the most ambitious computer networks attempted to date, but no one node is in control of the network.
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.
Computer communication network design: experience with theory and practice
The ARPA Network (ARPANET) project brought together many individuals with diverse backgrounds, philosophies, and technical approaches from the fields of computer science, communication theory,
Performance measurements on the ARPA computer network
An extensive measurement capability has been implemented in the Interface Message Processors of the ARPA network of computers to provide insight into network behavior, and to support the analytic and simulation modeling work being done at UCLA.
The network control center for the arpa network
The present paper briefly describes the NCC hardware; discusses such software issues as NCCrelated routines in the IMPs, datacollection and interpretation mechanisms, line status determination, IMP status and program reloading, and Host and line throughput; details NCC operations (manning, problemhandling procedures, track record); and summarizes overall NCC experiences and future plans.
Function-oriented protocols for the ARPA computer network
It is now appropriate to review the development of protocols which have been constructed to promote particular substantive uses of the ARPANET, namely function-oriented protocols.
Topological considerations in the design of the ARPA computer network
The ARPA Network will provide store-and-forward communication paths between a set of computer centers distributed across the continental United States. The message handling tasks at each node in the
McROSS: a multi-computer programming system
An experimental "distributed" programming system which makes it possible to create multi-computer programs and to run them on computers connected by the ARPA computer network (ARPANET).
Extensions of packet communication technology to a hand held personal terminal
Packet switching of a kind, the telegram, persisted throughout this period but due to the high cost of switching and the limited demand for fast message traffic never attracted much attention.
