ESnet Launches 46 Terabits next-gen network


The Energy Sciences Network (ESnet) has unveiled ESnet6, the newest generation of the U.S. Department of Energy’s (DOE’s) high-performance network.

With more than 46 Terabits per second of bandwidth, ESnet6 features a significant increase in bandwidth over prior generations of the network, according to a statement by the Berkeley Lab. In 2021, ESnet carried over 1.1 exabytes of science data. Traffic on ESnet increases by a factor of ten every four years, according to the statement.

For more than 35 years, ESnet – headquartered at Berkeley Lab – has served as the “data circulatory system” for the DOE, connecting all of its national laboratories, thousands of DOE-funded researchers, and DOE’s scientific instruments and supercomputing centers, says the statement.

ESnet6 new capabilities and services also include a dedicated 15,000 miles of fiber optic cable footprint, network backbone links ranging from 400 Gigabit per second to 1 Terabit per second for record-time data transfers, along with customizable network services via a new automation platform, and a future programmable API platform.

ESnet6’s critical industry partnerships include collaborations with Lumen Technologies, Ciena, Infinera, Nokia, and AMD.
