DotGrid platform is a Grid infrastructure integrated with a set of open and standard protocols recently implemented on the top of Microsoft .NET in Windows and MONO .NET in UNIX/Linux. DotGrid infrastructure along with its proposed protocols provides a right and solid approach to targeting other platforms, e.g., the native C/C++ runtime. In this paper, we propose a new file transfer protocol ca...

The existing designs and solutions for web caching systems commonly make caching decisions based on document or uniform resource locator (URL) information. While this conventional approach works, the authors deliver insights into the alternative approach using site information for web caching design. This site-based approach makes caching decisions based on the website that an object belongs to...

Distributed multimedia applications require performance guarantees from the underlying network subsystem. Ethernet has been the dominant local area network architecture in the last decade, and we believe that it will remain popular because of its cost-eeectiveness and the availability of higher-bandwidth Ethernets. We present the design, implementation and evaluation of a software-based timed-t...

This paper describes the design, goals, and details of NetStream, a C++ class containing services for communicating information through a network. The services in NetStream have been developed for running both in local as well as in wide area networks; therefore, it provides message passing in a manner that makes it useful for a large class of parallel programs. The services in NetStream have b...

The focus of the paper is on resource engineering for supporting Service Level Agreements (SLAs) in IP networks. We review some of the recent developments in Internet service architecture and protocol developments as well as some of the most important challenges still to be considered. An important performance metrics that must be considered in developing the new Internet is regarding the delay...

Remote Direct Memory Access (RDMA) has been proposed to overcome the limitations of traditional send/receive based communication protocols. The immense potential of RDMA to improve the communication performance while being extremely conservative on resource requirements have made RDMA the most sought after feature in current and next generation networks. Recently, there are many active efforts ...

Between April of 1994 and March of 1995 the University of Oregon worked with U S WEST and a number of other participants in an extensive technical trial of ATM equipment and services. This paper shares experiences and lessons learned during that trial. A primary area of emphasis during the trial was a complex mixture of ATM LAN and WAN capabilities. ATM connectivity was extended to high-end des...

This paper introduces a new load balancing algorithms, called LDMA (Load balancing using Decentralized decision-making Mobile Agents) and WLDMA (WAN Load balancing using Decentralized decision making Mobile Agents) which distributes load among local and geographically distributed web servers connected in a mesh topology, by a communications network. The performance of LDMA is compared with MALD...

SOA and Web Services technologies have been increasingly applied to network centric C2. In this paper, a service‐oriented C2 software architecture is firstly proposed based on SOA ideas and Web services technology to provide framework and guidance to service integration in future service‐oriented C2 systems, in which software and capability of C2 systems often are wrapped web serv...
