    The interconnection of token-ring local area networks (LANs) via store-and-forward bridges is considered. The mean-packet-delay performance of a system of token rings connected in series is analyzed by approximating the interarrival times at the bridges by renewal processes. The approximation gives simple formulas for the mean waiting times and agrees reasonably well with simulation results in mos... View full abstract»

    The author examines local-area-network standards from the perspective of what are called anticipatory, or marketing, standards. It is noted that in the past, standards have usually provided a document trail for product decisions, especially in the more mature industries. Within the information technology (IT) industry, however, the trend is changing to one of anticipatory standards: standards that... View full abstract»
