U.S. Lab Considers SDN for Growing ESnet Research Network


Inder Monga of the Lawrence Berkeley National Laboratory is responsible for a U.S. Department of Energy network that’s doubling in capacity each year. By 2020, the research network that connects scientists in the U.S. and Europe is projected to carry an exabyte of data each month.

Monga, CTO at Energy Sciences Network (ESnet), can’t satisfy such a high demand for capacity by building a larger network each year. “We cannot keep growing our network cost at an exponential rate,” he said. “Otherwise, our taxes will go up exponentially.”

ESnet is an unclassified network that connects more than 40 Department of Energy research sites, including the National Laboratory system and its supercomputing facilities. ESnet also connects to 140 research and commercial networks globally.
