As computers become pervasive in the home and community and homes become better connected, new applications will be deployed over the Internet. Interactive Distributed Applications involve users in multiple locations, across a wide area network, who interact and cooperate by manipulating shared objects. A timely response to user actions, which can potentially update the state of the objects, is...

The growing traffic of WWW related services requires the development of efficient protocols for reducing traffic, balancing load, and improving service time. One way of achieving these effects is via caching or replication. Studies like [Bestavros et al, 1995] show that simple demand-driven caching is not enough, and that aggressive caching policies have to be adopted. One such policy is prefet...

Web portal applications that dynamically generate results in response to user requests are more popular than ever. Such portal applications usually consist of a business logic component and a very large database, or databases that hold the portal’s content. Despite efforts to speed up response generation, ever-rising user demand means that replication of a portal’s logic and database will be ne...

The growing popularity of XML Web Services is resulting in a significant increase in the proportion of Internet traffic that involves requests to and responses from Web Services. Unfortunately, web service responses, because they are generated dynamically, are considered “uncacheable” by traditional caching infrastructures. One way of remedying this situation is by developing alternative cachin...

The explosion of content in distributed information retrieval (IR) systems requires new mechanisms in order to attain timely and accurate retrieval of unstructured text. In this paper, we investigate using partial replication to search a terabyte of text in our distributed IR system. We use a replica selection database to direct queries to relevant replicas that maintain query effectiveness, bu...

The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

To improve the scalability of the Web it is common practice to apply caching and replication techniques. Numerous strategies for placing and maintaining multiple copies of Web documents at several sites have been proposed. These approaches essentially apply a global strategy by which a single family of protocols is used to choose replication sites and keep copies mutually consistent. We propose...

Up to now, more and more people use Internet storage services as a new way of sharing. File sharing by a distributed storage system is quite different from a specific sharing application like BitTorrent. And as large file sharing becomes popular, the data transmission rate takes the place of the response delay to be the major factor influencing user experience. This paper introduces strategies ...
