Research community looks to SDN to help distribute data from the Large Hadron Collider

When the Large Hadron Collider (LHC) starts back up in June, the data collected and distributed worldwide for research will surpass the 200 petabytes exchanged among LHC sites the last time the collider was operational. Network challenges at this scale are different from what enterprises typically confront, but Harvey Newman, Professor of Physics at Caltech, who has been a leader in global scale networking and computing for the high energy physics community for the last 30 years, and Julian Bunn, Principal Computational Scientist at Caltech, hope to introduce a technology to this rarified environment that enterprises are also now contemplating: Software Defined Networking (SDN). Network World Editor in Chief John Dix recently sat down with Newman and Bunn to get a glimpse inside the demanding world of research networks and the promise of SDN.

The first place to tackle SDN? In the WAN

Disruptive innovation in infrastructure is on the rise, and nowhere is that more evident than in the Software Defined Networking movement. But while much of the SDN discussion has focused on the data center, the better initial use case might be in the wide area network. One advocate of that approach is Michael Elmore, IT Senior Director of the Enterprise Network Engineering Infrastructure Group at Cigna, a global health service company headquartered in Bloomfield, Connecticut. Michael is also on the board of Open Network Users Group (ONUG). Network World Editor in Chief John Dix asked Elmore to participate in an email-based Q&A to explore the promise of Software Defined WANS.
