Paper Abstract:
|
In this paper, a study of the performance of six replacement policies taking into account only one content-type of documents each time (Application, Audio, Images, Text and Video) has been developed in order to implement a proxy cache that differences the type of traffic. The classical caching algorithms LRU, LFU and LFU-DA and the caching schemes specifically developed for Web documents GD-SIZE, GDSF and GD* have been studied. Using a trace log of a real proxy cache, a characterization of the main properties of the documents of each content-type has been performed. Finally, a trace driven simulation study of the performance of the six replacement policies has been developed for the traffic generated by each content-type considered. In that way we can conclude which are the replacement policies that better perform for each content-type and cache size. |
