The benefits of Web cache prefetching are well understood, and so prefetching has been implemented in a number of commercial products. This paper argues that the current support for prefetching in HTTP/1.1 is insufficient because prefetching with GET is not good. Existing prefetching implementations can cause problems with undesirable side-effects and server abuse, and the potential for these p...

Networked multiplayer video games have become enormously popular over the past two decades. Recently the capabilities of traditionally-designed game servers have begun to be outstripped by the demands of vast numbers of players, motivating re-thinking of the fundamental server design. This project proposes a novel architecture for highly scalable networked multiplayer games, and examines the po...

We describe a scalable architecture, particularly well-suited to cloud-based computing, which can be used for Web-deployment of spoken dialogue systems. In common with similar platforms, like WAMI and the Nuance Mobile Developer Platform, we use a client/server approach in which speech recognition is carried out on the server side; our architecture, however, differs from these systems in offeri...

There have been many studies on the management of personal information such as PIN code, password, etc. Most schemes include a server containing explicit personal information, and if one can attack this server successfully, then he/she can reach whole personal information on the server. Since information is centralised, the responsibility for services and information is also centralised. There ...

Oblivious RAM (ORAM) garbles read/write operations by a client (to access a remote storage server or a random-access memory) so that an adversary observing the garbled access sequence cannot infer any information about the original operations, other than their overall number. This paper considers the natural setting of Oblivious Parallel RAM (OPRAM) recently introduced by Boyle, Chung, and Pass...

A software interceptor is a procedure or object that interposes itself between an invoking client and an invoked server software entity. Procedural interceptors can redirect procedure invocations to alternative procedures that are selected dynamically at run time. Procedural interceptors are useful for program profiling, tracing, dynamic delegation of operation implementation, and interactive d...

We consider the stability of parallel server systems under the longest queue first (LQF) rule. We show that when the underlying graph of a parallel server system is a tree, the standard nominal traffic condition is sufficient for the stability of that system under LQF when interarrival and service times have general distributions. Then we consider a special parallel server system, which is know...

In this paper, a technique for enhancing viewing capabilities of web-based clients, called the Super Plug-in Module (SPM), is proposed. By utilizing the collaborative client-server architecture, clients can view various types of documents through the help of an application server. The application server performs document transcoding operations while acts as a proxy at the same time, thus allevi...

Every machine plays roles of client and server simultaneously in a peer-to-peer (P2P) network. Though a P2P network has many advantages over traditional client-server models regarding efficiency and fault-tolerance, it also faces additional security threats. Users/IT administrators should be aware of risks from malicious code propagation, downloaded content legality, and P2P software’s vulnerab...
