Abstract:
The TeraPaths project at Brookhaven National Laboratory is pioneering a framework that enables the scheduling of network resources in the context of data-intensive scientific computing. Modern wide area networks, such as ESnet and Internet2, have recently started providing network resource reservation capabilities in the form of virtual circuits. The TeraPaths framework utilizes these circuits and extends them into end-site local area networks, establishing end-to-end virtual paths between end-site hosts. These paths are dedicated to specific users and/or applications and provide guaranteed resources, minimizing or eliminating the adverse effects of network congestion. In this article, we present an overview of TeraPaths and examine issues raised by the end-to-end resource reservation-based networking paradigm as well as implications and benefits for end users and applications. We also discuss scalability issues and optimization techniques for wide area network circuit reservations.
