Session Abstract

TeraPaths is a Department of Energy funded network research project to support efficient, predicable, and prioritized peta-scale data replication in modern high-speed networks. This talk presents the TeraPaths end-to-end network management framework, which enables the dedication of network resources to specific data flows across multiple administrative network domains. The primary motivation behind this work comes from the world of modern high energy and nuclear physics (Large Hadron Collider - LHC, Relativistic Heavy Ion Collider - RHIC), where extremely large quantities of experimental and analysis data need to be shared across the globe among scientists participating in various international experiments. The default best-effort behavior of these networks may easily cause users/applications to suffer interruptions and other adverse effects. New network resource management capabilities are necessary to guarantee the success of long-term transfers and ensure the timely delivery of priority data.

The TeraPaths framework utilizes Differentiated Services-based QoS and Policy-Based Routing techniques in combination with automated invocation of WAN domain control services to create and manage on-demand, true end-to-end QoS-aware network paths dedicated to data flows of authorized users/applications in a transparent and scalable manner. Such flows are steered into their
