Cím:	The impact of heterogeneous traffic on the performance of Proxy Cache servers / Bérczes Tamás, Sztrik János
Dátum:	2011
Megjegyzések:	The focus of the paper is to examine the performance behavior of Proxy Cache serverswhen we use heterogeneous traffic. We describe the multi-class queuing network model of theProxy Cache server, where we separate the requests in two classes by virtue of their size. If thesize of the requested document is greater than average we put it into class a. In the oppositecase, when the size of the requested file is small we put it into class b. We have calculatedthe overall response time with and without a Proxy Cache server. We analyzed how variousfactors affect the performance of a Proxy Cache server when we use heterogeneous traffic. Ingeneral when the arrival rate of requests increases, then the response time increases as wellregardless of the existence of a Proxy Cache server. Increasing the percentage of the class athe response time increases too. When we use a higher percentage of the class a and we usea high arrival rate, then the response time gap is more significant between the cases with andwithout a Proxy Cache server. Using a low percentage of class a files, a low arrival rate andlow cache hit rate probability we get higher response time in presence of a Proxy Cache server.Several numerical examples illustrate the effect of arrival, external arrival rate and the filesize of class a and class b on the mean response times.
