This paper present a new method in which delay and scale of windows of TCP messages are used for evaluating performance of broadband. Comparison between delay or scale of window s of samples is the core idea of the method. There are two kinds of comparison. One is absolute terms of above-mentioned...
We evaluate two mechanisms for setting prices in a QoS-enhanced network with congestion-sensitive pricing and resource allocation based on users' willingness to pay. In the first model, the congestion-sensitive component of the price is calculated by tatonnement, with the price adjusted gradually to drive down the user demand to the supply level of network resources. In the second model, each user...
