    The author designs and analyzes the performance of a remote terminal protocol (RTP), called TAP, for use as a terminal access protocol in a 4BSD UNIX environment. He characterizes the workload by tracing user terminal activity on a multiuser timeshare machine. The trace analysis shows that user terminal traffic is bursty, with 99% of the traffic from the terminal being one byte long. The trace res... View full abstract»

  • Using multicast communication for dynamic load balancing in local area networks

    Publication Year: 1989, Page(s):77 - 84
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (600 KB)

    A multicast-based algorithm is proposed for load balancing in a local computer network. The ability of a host to make its membership known to a multicast group based on its workload makes it possible to send a transfer request only to those hosts which have lower workload than the host that wants to transfer a task. This reduces the overhead of load balancing because a host does not waste computat... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (600 KB)

    A cached state approach to connection management is described. The approach, based on the request-response model of communication, uses implicit connection setup, and dynamic caching of communication state records beyond the time needed by the transport layer. The caching of connection records can reduce callbacks on isolated requests if secure or authenticated communication is required. The cache... View full abstract»
