DOE Network Researchers Get a Consistent View with New perfSONAR Network Monitoring

January 25, 2006

In collaboration with GEANT2 and Internet2 networks, ESnet has released the first working prototype of a new network monitoring architecture, provisionally named perfSONAR. The prototype is now providing information on link capacity and link utilization across the circuits of the Abilene, ESnet, GEANT, UNINETT, and SWITCH backbone networks. Access is being provided initially to a restricted…  Read More

OSCARS Provides On-Demand Circuit Provisioning Service

January 25, 2006

ESnet is developing and deploying a prototype service that enables on-demand provisioning of guaranteed bandwidth, secure virtual circuits within the ESnet production network. The service, called OSCARS (ESnet On-Demand Secure Circuits and Advance Reservation System), is designed specifically to meet the science discipline-driven network requirement of dynamically provisioned quality of service…  Read More

ESnet Plays Key Role in International Effort of Building Trust on Grids

January 20, 2006

When the International Grid Trust Federation (IGTF) was established in October 2005 during the 15th Global Grid Forum (GGF) in Boston, much of the groundwork for the project had been laid by ESnet over the past three years. With the establishment of the ITGF, users of Grid computing worldwide took a step closer to accessing computers and information in 50 countries in Asia, the Americas and…  Read More

ESnet Increases 10 Gb/s Circuits/Connections by 880 Percent in 2005-06

January 10, 2006

ESnet will install at least 44 new 10 Gb/s circuits and connections in 2005‑06. Half of these were completed and in production by November 2005, and the remaining connections should go into production by the end of spring 2006. By comparison, only five 10 Gb/s links were in place in January 2005. These new connections are part of a new architecture that will provide 20‑40 Gb/s metro area…  Read More
