Pradeeban Kathiravelu is a PhD student researching how to use SDN to improve QoS and data quality in multi-tenant data center networks. His approach is to deploy an extended SDN controller architecture to increase QoS and enhance data quality for stored and processed data. He has published several papers on this topic and ongoing work includes the SMART project, with promising results showing improved data isolation, quality, and QoS guarantees through the use of SDN.
