—Operating unprotected network links for international collaboration between research and education communities, subject to a high-availability production service requirement, is challenging. Provisioning circuits, maintaining a loop-free network topology, and configuring multi-path redundancy to provide high availability are complex processes, which(More)
In this paper, we investigate the integration of heterogeneous network monitoring data. Specifically, we will synchronize and integrate flow-level records, exemplified by Cisco NetFlow, and packet-level traces, exemplified by NLANR PMA. The integration can facilitate cross-validation and complementary utility. However, finding the correspondences of(More)
The Center for Internet Augmented Research and Assessment (CIARA) NSF CI-TEAM demonstration project "CyberBridges" is a new model for creating a new generation of scientists and engineers who are capable of fully integrating Grid into the whole educational, professional, and creative process of their respective disciplines. CyberBridges augments graduate(More)

—New scientific instruments that are being designed and deployed in the coming years will dramatically increase the need for large, real-time data transfers among scientists throughout the world. One such instrument is the Large Synoptic Survey Telescope being built in Chile that will produce 6.4 GB images every 17 seconds. This paper describes an ongoing(More)
time network simulation into the GENI "ecosystem". We are extending our existing real-time large-scale network simulator PRIME to become part of the GENI federation. PrimoGENI will support large-scale GENI experiments with millions of simulated network entities (hosts, routers, and links) and thousands of emulated elements running unmodified network(More)
