This paper presents a novel dynamic and scalable caching algorithm of proxy server with a finite storage size for multimedia objects. Among the multimedia such as text, image, audio and video, video is a dominant component in terms of the performance of proxy server due to its traffic characteristics. For the fast caching process, caching sequences for videos are obtained to decrease both the b...

The BDI-oriented multi-agent programming language 2APL allows the implementation of an agent’s beliefs in terms of logical facts and rules. An agent’s beliefs represent information about its surrounding environment including other agents. Repeated querying of the beliefs by the 2APL interpreter causes unnecessary overhead resulting in poor runtime performance of the interpreter. We propose an e...

We present a new approach for accelerated global illumination computation in scenes with glossy surfaces. Our algorithm combines sparse illumination computation used in the radiance caching algorithm with BRDF importance sampling. To make this approach feasible, we extend the idea of lazy illumination evaluation, used in the caching approaches, from the spatial to the directional domain. Using ...

Caching certain results of computation has been shown to be an effective performance enhancement tool in the context of complex objects and rule-based systems [JHIN88, STONSO]. In this paper we establish certain analytic results about such caching. In particular we show that caching the identifiers of the constituent subobjects may prove useful when the set of subobjects of an object is represe...

Web caching is an important technology for reducing Internet access latency, alleviating network traffic, and spreading server load. An important issue that affects the performance of web caching is caching architecture, in which several caches are usually federated for making caches cooperate on a large scale and effectively increase the cache population. Transparent data replication is such a...

Streaming media has contributed to a significant amount of today’s Internet traffic. Like conventional web objects (e.g., HTML pages and images), media objects can benefit from proxy caching; yet their unique features such as huge size and high bandwidth demand imply that conventional proxy caching strategies have to be substantially revised. This article discusses the critical issues and chall...

Information-Centric Networking is a name based internet architecture and is considered as an alternate of IP base internet architecture. The in-network caching feature used in ICN has attracted research interests as it reduces network traffic, server overload and minimizes latency experienced by end users. Researchers have proposed different caching policies for ICN aiming to optimize performan...

Since long latency due to remote memory access could be tolerated by rapidly switching to another thread in multithreaded processing, caching I-structure data is expected to have less benejicial effect on the pe$ormance than caching ordinary data. In this papel; we show that caching I-structure data could improve the overall performance in spite of latency tolerating property of multithreading....

In Web-based searching systems that access distributed information providers, efficient 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 improper for such a task. In this work, we devel...

The advent of the Web service brought out the explosive growth of Internet, which necessitates a scheme to reduce the netwrok traac. Caching is a popular method in reducing such traac, and it is widely used in many Web servers, clients, and proxy servers. Since an object of Web service is accessed as a whole, the caching scheme for such object must be diierent from others that usually treat a p...
