NERSC Now Connected to ESnet and Beyond at 100G

All network traffic flowing in-and-out of the Department of Energy’s National Energy Research Scientific Computing Center (NERSC) is now moving at 100 Gigabits per second (Gbps)—this includes everything from email to massive scientific datasets. Jason Lee, who leads NERSC’s Network and Security Team, worked with engineers at the DOE’s Energy Sciences Network (ESnet) to set up a 100Gbps Science DMZ, which gives NERSC network engineers the ability to set up multiple private circuits using software-defined networking (SDN). With these tools, NERSC staff can help remote scientists who may see their data transfers slow down due to firewalls at their local campuses achieve a true 100Gbps end-to-end connection. Additionally, ESnet engineers also helped NERSC set up a system to announce their own address space. This allows the center to separately route traffic to any research or education (R&E) site or separate R&E traffic from the commodity Internet.
