TL;DR: In this paper, an algorithm is presented for reliable broadcast of routing information throughout a network. But it does not consider the possibility of long-delayed packets, line and node outages, network partitions, hardware failures, and a history of arbitrarily corrupted databases throughout the network.

TL;DR: This paper outlines the principles on which the U.S. Department of Defense packet internet architecture is based and characterizes some of the protocols which implement the architecture.

TL;DR: The paper considers packet switching in multiple radio channels with random access using a markovian model and an approximate model called “fluid approximation” and calculates the stability region.

TL;DR: The paper concludes that the data communication ring is a sound idea that will prove its value on operational rather than theoretical issues.

TL;DR: An efficient collision-free channel-access protocol for cable or radio networks with an arbitrary spatial fixed node configuration that optimally employs available information on network topology to provide performance characteristics that are at least as good as and in most cases much better than those of other published protocols.

TL;DR: A strategy of military standardization is outlined which adopts commercial standards where they apply and supplements these with special military standards as needed to satisfy unique military requirements.

TL;DR: The experimental results include the processing times for a data link connection/disconnection, the synchronous delay time for a read/write operation matching, and the data transmission speed and efficiency of both the multiplex mode and the burst mode.

TL;DR: The benefits to be gained by ensuring that the user accessible interface to a local area network provides identical functionality to that offered over a long haul network argue for a subset of features common to both types.

TL;DR: The US Department of Defense by virtue of its needs, investigations, and accomplishments to date, is eminently qualified to contribute significantly to the development of data protocol standards.

TL;DR: The agreements (by June 1982) which have been achieved on the international standardization level with respect to the Transport Layer are presented and the specific performance of each protocol class is given.

TL;DR: A short overview of the major categories of transborder data flows relevant to IIASA's work, and how the gateway-network handles them are presented.

TL;DR: The relation between inhouse and public videotex systems are analyzed and it is shown that these systems are and should not be independent of each other and that they can and should complement each other rather than complete.

TL;DR: The table-based method, using an additive uniform random number generator for selection from the table, was determined to be a satisfactory method considering NBSNET's constraints, and is being used to generate artificial traffic for continuing local network research experimentation.

TL;DR: An improved approach based on the new concept of the “contrained average” is presented, a methematical construct which derives an appropriate equivalent traffic level L(f,ϵ) from an existing bona fide circuit-switched system.

TL;DR: A contention transmission algorithm for local networks which is related to the p-persistent family of algorithms previously analyzed by Kleinrock and Tobagi is presented, which incorporates an automatic acknowledgement signal which is sent by the receiving station immediately after each packet is correctly received.

TL;DR: Alternative shared channel access procedures for mobile packet radio data/voice systems with natural pauses in speech are examined, showing a reduction of 30–35% in bandwidth requirements can be obtained without serious performance loss.

TL;DR: A method for expressing expected patterns (policy) of message transmission is given, called the Task Graph Language, and the mechanism to perform the runtime checking of observed vs. expected behaviour is called Token Lists.

TL;DR: ALIS (Automated Library Information System) comprises a catalogue search system combined with a circulation control system with bar-code readers and the user may obtain not only the bibliographic records for the retrieved documents but also information about their immediate status.

TL;DR: An analytical tool for the performance study of some protocols for satellite broadcast channel is described and a probabilistic method is introduced and the obtained results are compared with those obtained by simulation.

TL;DR: An interface between CSIRONET and Digital Equipment Corporation's ANF-10 network products has been developed and this interface has been used to connect CSirONET to the ANf-10 based networks of two Australian Universities.

TL;DR: This work presents some restrictions that ensure that requests are received at a server in the same order that they are sent, and shows how each server can safely service requests in the order of arrival.
