Performance Modeling of Proxy Cache Servers
نویسندگان
چکیده
The primary aim of the present paper is to modify the performance model of Bose and Cheng [1] to a more realistic case when external visits are also allowed to the remote Web servers and the Web servers have limited buffer. We analyze how many parameters affect the performance of a Proxy Cache Server. Numerical results are obtained for the overall response time with and without a PCS. These results show that the benefit of a PCS depends on various factors. Several numerical examples illustrate the effect of visit rates, visit rates for the external users , and the cache hit rate probability on the mean response times.

متن کاملA quantitative study of Web cache replacement strategies using simulation
The Web has become the most important source of information and communication for the world. Proxy servers are used to cache objects with the goals of decreasing network traffic, reducing user perceived lag and loads on origin servers. In this paper, we focus on the cache replacement problem with respect to proxy servers. Despite the fact that some Web 2.0 applications have dynamic objects, mos...
متن کاملEvaluation of Performance of Cooperative Web Caching with Web Polygraph
This paper presents a framework for evaluating the performance of cooperative Web cache hierarchies. Web Polygraph is employed to provide an environment for simulation, to generate desired workloads, and to obtain performance statistics from the standpoint of clients and servers. Squeezer, a proxy cache log analysis tool, provides detailed cache statistics including information about cache coop...
متن کاملExploiting Metadata of Absent Objects for Proxy Cache Consistency
Caching at the Web proxy server plays an important role in reducing the response time, the network tra c, and the load of Web servers. Many recent studies have proposed and examined the replacement and consistency policies for the proxy cache, which plays a central role in the performance of caching components. For better performance, they exploit various metadata of Web objects, such as the re...
متن کاملImproving Web Access Efficiency Using P2P Proxies
Recent studies have shown that caching data at the proxy server can improve the user response time for web document retrieval. However, a single cache proxy has a limited cache space, thus the amount of data that can be cached is limited. In this paper, we organize the distributed proxy servers into a group of peer-to-peer cache proxies. By exploiting the aggregate cache space and computing pow...
