A switching fabric performance evaluation model based on double-indicator utility function

摘要

Utility function theory in microeconomics is introduced into the switching fabric performance evaluation in this paper. We propose a new switch performance evaluation model—based on delay utility function, and with utility maximization theory to find out the optimum allocation scheme of network resources. And then we extend the model, integrate the two most closely to the nature of traffic flow and user-intuitive feel indicator, the delay and bandwidth, into our model, making the evaluation more comprehensive, intuitive and practical. That is the double-indicator evaluation model. The solution make us can use the existing network resources effectively and try our best to provide a better QoS for various traffics.
