    The results of a series of experiments designed to measure the performance of Intel's distributed file system for an Ethernet local area network are summarized. The file system allows processes to access files stored on any node of the network, provided the process has the appropriate access permission. From informal observations, the authors theorized that system performance declined significantl... 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»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (484 KB)

    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»
