Object access distribution in the Web is governed by Zipf’s law, in general. This property leads to effective Web caches, which store the most popular objects and typically employ the LFU replacement policy, which achieves high, and often the highest, cache hit rates. However, Web cache design based only on Zipf’s law has two main disadvantages: (i) it does not exploit the temporal and spatial ...

Web caching is a significantly important strategy for improving Web performance. In this paper, we design SmartCache, a router-based system of Web page load time reduction in home broadband access networks, which is composed of cache, SVM trainer and classifier, and browser extension. More specifically, the browser interacts with users to collect their experience satisfaction and prepare traini...

As shared last level caches are widely used in many-core CMPs to boost system performance, partitioning a large shared cache among multiple concurrently running applications becomes increasingly important in order to reduce destructive interference. However, while recent works start to show the promise of using replacement-based partitioning schemes, such existing schemes either suffer from sev...

Replacement policy defines the enhancement factor in deciding the system performance. Many different policies have different effects on the system performance, but still there exist performance gap between processors and memory system. In the IPTV services it provides the various services to the user as per their request, the proposed policy is based on the no of hit count and miss count on the...

Web caching plays an important role in many network services. Utilization of the cache in each level (server, proxy, and client) of network forms a web caching hierarchy. A major problem of the hierarchical caching is the poor performance due to the interference between upper-level and lower-level caches. This paper investigates the replacement algorithms applied in the network caching hierarch...

In this paper, we look at a number of policies for managing a le system cache in a web server. Traces from NCSA WorldWide Web (WWW) server are used in this study. We study several caching policies for improving the overall performance of such a server and show that request response time can be improved by some of the replacement policies that take size of the request into account. It is shown t...

Mobile web access log file plays an important role in the analysis about demand of mobile terminal market or user behavior. However, the log file data is highly dimensional, disorganized and semi-structured, which heightens the difficulty of data extracting accuracy; while it generates and transmits continuously, which poses an extracting efficiency challenge. It is highly desirable to extract ...
