16:25 Dynamic Circuit Networks for the University

Internet2 has been working with Fermi and BNL to enable LambdaStation and TeraPaths software to setup dynamic circuits. This feature would allow US-ATLAS sites the ability to establish short term circuits that could carry the T1 <--> T2 traffic flows. Service trials and experiments have been going on for several months now and it would be good for the US-ATLAS T2 & T3 community to learn about this service. The goal would be to let the campus physicists know what the DCN service is, how it is currently being used, the short & long term plans, and what the campus and regional network operators would need to do to let the US-ATLAS physicist use it.

Speaker: John Vollbrecht (Internet2)
