Berkeley Lab to Develop World’s Fastest Computer Network

August 10, 2009

As scientists in a wide variety of disciplines increasingly rely on supercomputers and collaboration with colleagues around the world to advance their research, managing and sharing the mountain of data generated by their investigations will soon become a choking point. In order to facilitate such data-intensive research, ESnet, the Department of Energy’s high-performance networking…  Read More

ESnet's OSCARS Allows Users to Reserve Bandwidth

July 31, 2009

Most network traffic is transmitted on a “best effort” basis, meaning that there's a pretty good chance the packets will arrive as intended. But for the Department of Energy (DOE) researchers around the world who are sharing massive scientific datasets, the “best” just isn't good enough. Now, researchers can reserve bandwidth on Energy Sciences Network's (ESnet) circuit-oriented Science…  Read More

Energy gets jump on implementing DNS security on ESnet research network

July 23, 2009

The Energy Department has started implementing Domain Name System Security Extensions on its high-performance Energy Sciences Network (ESnet), using a commercial appliance to digitally sign DNS records and manage cryptographic keys. The first zones on the network were signed July 8 and it will be at least another month before necessary software updates and testing are completed, and signed…  Read More

ESnet Rolls Out IPv6 Network Management System

June 15, 2009

Although it has been a network protocol standard for more than 10 years, IPv6 (Internet Protocol version 6) has only been minimally implemented by the networking community. But that could change now that the U.S. Department of Energy’s Energy Sciences Network (ESnet) has deployed a production IPv6 management system across its entire network. ESnet is one of the world’s leading networks…  Read More

ESnet Links NERSC to HPWREN to Help in Exposing Cosmic Transients

June 15, 2009

An innovative new sky survey, called the Palomar Transient Factory (PTF), will utilize the unique tools and services offered by the Department of Energy's (DOE) National Energy Research Scientific Computing Center (NERSC) at the Lawrence Berkeley National Lab (Berkeley Lab) to expose relatively rare and fleeting cosmic events, like supernovae and gamma ray bursts. In fact, during the…  Read More

Speeding Up Science Data Transfers Between Department of Energy Facilities

May 18, 2009

As scientists conduct cutting-edge research with ever more sophisticated techniques, instruments, and supercomputers, the data sets that they must move, analyze, and manage are increasing in size to unprecedented levels. The ability to move and share data is essential to scientific collaboration, and in support of this activity network and systems engineers from the Department of Energy's…  Read More

PerfSONAR Helps Accelerate Big Science Collaborations

April 28, 2009

In the arena of high-performance networking, it’s easy to track down “hard failures” such as when someone breaks or cuts through a fiber link. But identifying “soft failures,” like dirty fibers or router processor overload, is challenging. Such soft failures still allow network packets to get through, but can cause a network to run 10 times slower than it should and also account for the…  Read More

ESnet Connects STAR to Asian Collaborators

April 28, 2009

The Department of Energy's Energy Sciences Network (ESnet), the Korea Research Environment Open Network2 and the Global Ring Network for Advanced Applications Development achieved a sustained data transfer rate of 1 gigabit per second (Gbps), equivalent to transporting 120 minutes of video per second, between the Brookhaven National Laboratory in New York and the Korea Institute of Science and…  Read More

ESnet Update: Hardware Upgrades to Regional Network Sites

March 30, 2009

Throughout February and March, ESnet engineers continued to upgrade hardware and network capabilities at its regional network sites across the country. Upgrades to the Bay Area Metropolitan Area Network (BAMAN) were completed earlier this month when Cisco routers at NERSC’s Oakland Scientific Facility and the Joint Genome Institute in Walnut Creek were replaced with hardware from Juniper’s MX…  Read More
