Dynamic proxy-cache multiplication inside LANs

Abstract

Proxy-cache deployment in LANs has become a current practice with well known benefits. For situations when a proxy-cache comes under constraints, due to increased load, and has to drop requests or perform cache replacement, we propose the alternative solution of cachesplitting. This means to dynamically deploy additional proxy-caches inside the LAN, and divert towards them some of the requests addressed to the original proxy-cache(s). By doing this, better response time, load balancing, higher availability and robustness of the service can be achieved than when using a single proxy-cache. © Springer-Verlag Berlin Heidelberg 2005.
