    The assignment of independent applications in a distributed system in conjunction with resequencing is studied in this paper using simulation techniques. Three scheduling policies are studied and compared. A probabilistic policy, and two policies that use an estimation of job service time, one deterministic and one adaptive. Their performance is examined for a variety of workloads. The impact on p... View full abstract»

    The transmission control protocol (TCP) has been mainly designed assuming a relatively reliable wireline network. It is known to perform poorly in the presence of wireless links because of its basic assumption that any loss of a data segment is due to congestion and consequently it invokes congestion control measures. However, on wireless access links, a large number of segment losses will occur m... View full abstract»

    In this paper we introduce and evaluate a method for optimizing the router arbitration policy in point-to-point networks. These networks use multiple high speed, low-cost routers to rapidly switch data directly between data sources and destinations. We assume that routers use an arbitration algorithm that has the ability to assign different priorities to different links thus controlling the distri... View full abstract»
