A proxy placement algorithm for the adaptive multimedia server

Abstract

Multimedia services are becoming widespread, while the network capacity can not keep up with the growth of user demands. Usually proxies are used to overcome the QoS degradation. One of the fundamental problems of applying proxies is to recognize the relevant set of proxy placement criteria, and to find a good algorithm. In this paper we propose a greedy algorithm variant, ams-greedy, that aims at taking into account the different property preferences of the proxy-server and the proxy-client links. We also analyse the consequences of the initial results. Keywords: Greedy algorithm, optimization, proxies, distributed multimedia. © Springer-Verlag 2003.
