In this paper, we present our research on WWW caching proxies. We drew some key conclusions on the service properties and caching policies, according to the results of our analysis of caching proxies. These conclusions include our recommendations on cache configuration and illustrate how choosing cache scenarios depends on the different requirements requested by the cache manager and different ...

First, we develop a model for streaming VBR{encoded continuous m...

Although caching has been shown to be an efficient technique to improve the performance of database systems, it also introduces the overhead and complexity in maintaining data consistency between the primary copies on servers and the cached copies on clients. Little research has been performed for data caching in the mobile ad-hoc network (MANET) environment where both servers and clients are n...

Content-Centric Networking (CCN) is a novel networking paradigm making named data the first class entity rather than IP address. That is, it cares about which data to fetch rather than which host to reach. One key feature of CCN is the content caching that CCN routers are caching named contents instead of IP addresses, which makes the effect of Denial-of-Service (DoS) attack different from in T...

Caching and prefetching are well known strategies for improving the performance of Internet systems. The heart of a caching system is its page replacement policy, which selects the pages to be replaced in a proxy cache when a request arrives. By the same token, the essence of a prefetching algorithm lies in its ability to accurately predict future request. In this paper, we present a method for...

In the upcoming world of Pervasive Computing, content adaptation is an essential concept to meet the heterogeneous requirements of web users using various web access technologies. However, content adaptation interferes with the effectiveness of web caching. Leveraging the advantages of web caching even in the world of Pervasive Computing is the subject of this paper. We present an approach that...

The Internet is growing rapidly in terms of both use and infrastructure. Unfortunately, demand is outpacing the capacity of the infrastructure, as evidenced by unacceptably long response times. To support current load and further growth, we must address this problem. Several caching strategies have been proposed in the literature; many have been implemented to improve the quality of service on ...

Semantic caching is a technique used for optimizing the evaluation of database queries by caching results of old queries and using them when answering new queries. CoopSC is a cooperative database caching architecture, which extends the classic semantic caching approach by allowing clients to share their local caches in a cooperative matter. Thus, this approach decreases the response time of da...

In Web-based searching systems that access distributed information providers, eecient query processing requires an advanced caching mechanism to reduce the query response time. The keyword-based querying is often the only way to retrieve data from Web providers, and therefore standard page-based and tuple-based caching mechanisms turn out to be ineecient for such a task. In this work, we develo...
