This paper describes the design of a distributed system built using Java that supports peer-to-peer communication among processes spread across a network. We identify the requirements of a software layer that supports distributed computing, and we propose a design that meets those requirements. Our primary concerns are (I) the identification, specification, and implementation of software components...
We use the term ubiquitous supercomputing to refer to systems that integrate low and mid range computing systems, advanced networks, and remote high end computers with the goal of enhancing the computational power accessible from local environments. Such systems promise to enable new applications in areas as diverse as smart instruments and collaborative environments. However, they also demand tools...
Undoubtedly, multimedia electronic mail has many advantages in exchanging information electronically in collaborative work. The existing design of an e-mail systems architecture is inefficient in exchanging a multimedia message which has a much larger volume, and requires more bandwidth and storage space than the text-only messages. We present an innovative method for exchanging multimedia mail messages...
Discusses the emergent World Wide Web-based distributed environments for high-performance computing and communications (HPCC) on the National Information Infrastructure (NII) with the focus on Java as an enabling technology. We start with a review of the past, present and near-term future of the "Java phenomenon", exposed in the background of some related previous approaches towards a distributed...
A collaborative multimedia environment (CME) allows users to works remotely on common projects by sharing applications (e.g. CAD tools, text editors, white boards) and simultaneously communicate audiovisually. Several dedicated applications (e.g. MBone tools) exist for transmitting video, audio and data between users. Due to the fact that they have been developed for the Internet, which does not provide...
The information retrieval systems on a wide area distributed network, such as the World-Wide Web (WWW), become popular among the extremely large number of users. The caching proxy has an important role in these systems for improving their accessibility and serviceability. The caching proxy mechanism is discussed in this paper. First, the role and structure of the caching proxy is explained, and two...
