We’ve got Yoo


Professor Ben Yoo

ESnet is pleased to announce that UC Davis Professor S.J. Ben Yoo has been granted a joint faculty appointment with Berkeley Lab, formalizing a long-term relationship.  Yoo will be collaborating on research projects with ESnet to develop Terabit optical networks of the future to meet the upcoming data challenges triggered by Exascale thinking within the DOE.  It is an interesting research challenge, including architecture studies, software developments and networking experiments on ESnet’s ANI testbed. Yoo will also be collaborating with LBNL researchers at NERSC for applications of optical networking within high-end data centers.

“Ben is the type of highly credentialed network research scientist that we hope will take full advantage of the testbed infrastructure we are making available to the community.” said Steve Cotter, head of ESnet.

In a talk this week at Joint Techs http://bit.ly/cAtNt4, Yoo discussed the potential of next generation all-optical Label Switching (OLS) networking, a technology he invented. OLS can seamlessly integrate packet, flow, and circuit traffic. OLS has the potential to fit well within the  industry standard MPLS and GMPLS architectures, and recent experimental results show very good characteristics like extremely low latency (<100 ns) and scalability beyond 40 petabit/sec capacity. It has experimentally demonstrated a per-channel line rate of 100 Gb/s ~ 1.2 Tb/s. A centralized management station can leverage OLS to rapidly assess data flows based on real time collections of labels that contain statistical information about the data traffic.

Yoo has done extensive research with the ATD-Monet testbed in the Washington DC area, telecommunications standardization services at Bellcore, and testbed work at the Sprint Advanced Technology Laboratory. You can get a better sense of his work and research here.

We look forward to working with him on our ANI testbed as well. Yoo’s intention is to push the testbed to its limits. Should be a wild ride.
