    In optical communication, ideal amplification of the received signal leads to a limiting signaling rate of 1 nat per photon. This is much inferior to the optimum limit ofkTjoules/nat, which we can theoretically approach by counting photons. Practically, the rates we can attain by photon counting will be limited by how elaborate codes we can instrument rather than by thermal photons. View full abstract»

    A traffic study and the results of a full scale simulation of the No. 3 ESS switching network are presented. Following a brief description of the network and the simulation techniques, the various parameters affecting network performance are discussed and the load-service curves are given for these parameters. In particular, the network capacity is studied for various numbers of concentrator group... View full abstract»

    This paper analyzes the performance of a phase-locked loop driven by the photodetector current in an optical receiver. The variance of the phase-errors of the loop is found as a function of the relevant system parameters. The results are in good agreement with experimental data obtained via computer simulation.

    A Packet Radio Network is a store-and-forward packet system employing radio links. A Mobile Packet Radio Network generalizes this system by allowing every radio unit to be independently in motion. In this paper a model for the analysis of connectivity as a function of time in such a network is presented and used to solve for parameters of interest. The model and the related analysis are guides for... View full abstract»

    This paper presents a comprehensive review of the ARPANET routing algorithm, from its original implementation to our plans for future modifications. We hope that by collecting this information, and by providing considerable details, we can provide others with a useful reference document concerning some of the practical problems of network algorithm design. Much of the discussion below assumes a ba... View full abstract»
