The U.S. Department of Energy's 100 Gbps testbed provides a facility for researchers to solve the near-term challenges associated with deploying and operating science networks, while the dark fiber testbed can be used for research into disruptive technologies and approaches that are still not ready for production use.
The testbeds are operated by the Energy Sciences Network (ESnet), which is managed by Lawrence Berkeley National Laboratory. "Originally part of the now-completed Advanced Networking Initiative, the testbed features a set of fast end hosts at [the National Energy Research Scientific Computing Center] and Argonne, with a dedicated 100 Gbps connection linking them," says ESnet's Brian Tierney.
He notes that 100 Gbps research is important because with more experimental facilities coming online and others receiving major upgrades, the datasets are only getting bigger and harder to manage and share with other researchers. He says there have been three separate projects testing Remote Direct Memory Access Over Converged Ethernet (RoCE), all of which are exploring ways RoCE can work over a wide area network at 10 Gbps and 40 Gbps.
