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)
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 " CyberBridges " pilot project is an innovative model for creating a new generation of scientists and engineers who are capable of fully integrating cyberinfrastructure into the whole educational, professional, and creative process of their respective disciplines. CyberBridges augments graduate student education to include a foundation of understanding(More)
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 multipath redundancy to provide high availability are complex processes, which involve(More)

In this paper we present a distributed network monitoring system, which exploits MonALISA (Monitoring Agents in A Large Integrated Services Architecture), a distributed web service delivery infrastructure designed to collect and process the network monitoring information. We augment the capability of MonALISA with FlowTools, the popular NetFlow data(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)
