Caltech and university partners demonstrate 186 Gbps transmission

Caltech and a number of partner universities demonstrated 186 Gbps data transmission during the recent SuperComputing 2011 conference in Seattle.

Joined by network engineers and computer scientists from Caltech in addition to the University of Victoria, the European Center for Nuclear Research (CERN), University of Michigan, Florida International University and a few other partners, the 186 speed surpassed the 119 Gbps record set in 2009.

With more than enough speed to transfer two million gigabytes a day, the group achieved the speed with a 100 Gbps circuit, which was provisioned by Canada's Research & Education (R&E) providers BCNET and CANARIE.

Between the University of Victoria's data center in British Columbia and the Seattle Convention Center, the group transmitted a simultaneous rate of 98 Gbps in one direction and in the other direction 88 Gbps. An additional demonstration was conducted to transmit the same speeds from Seattle to other parts of the U.S. and to international partners in Korea and Brazil.

Interestingly, the test leveraged a commercially available 100 Gbps link versus going "over private networks under laboratory/testbed conditions."

While this was just an initial experiment, it illustrates the possibilities of optical and IP-based communications. In addition to providing potential benefits to the scientific research community, it will have an impact on helping service providers like Verizon, which is ramping up its 100G optical rollouts of its core network, where it can go beyond 100G.
