Global research infrastructure is undergoing a sea change like never before. World over, countries are trying to use their Research Infrastructure to consolidate efforts in every area of science and technology for creating "critical mass" in each area for addressing "large and complex" problems that challenge human race. National Knowledge Network of India has succeeded in bringing together the premier institutions in education and research and premier national laboratories. In a short span on 12 months, NKN has crossed 700 institutions and created several subject specific grids. Climate change grid, Brain Grid, and Cancer Grid are significant example of "subject-specific" grids. Perhaps, one should synergize the research groups across the Globe for generating more such "subject-specific" or "Task-specific" associations between research groups. The strength of NKN is derived from the underlying high bandwidth and low latency network. Designed with multiple levels of rings with bandwidth multiplying by at least 10 times (in some rings even a 100 times) from ring to ring as we traverse from end-user node to the core. Multiply connected routers ensure "shortening" of paths between nodes and enhance the resilience for time-sensitive high volume applications that are a hallmark of Global Science Cooperation. The talk will focus on "Next Steps"; Communication, Consolidation, Storage, and sharing with emphasis on Privacy and Security that are becoming sovereign concerns as well.
Dr. Raghavan is a Professor in the Computer Science and Engineering department at IIT Madras. His specializations include Architecture, Networks, Technology Enhanced Learning, and Cyber Security. Currently, he is serving as the Scientific Secretary (Rank of Secretary to Government of India) in the Office of the Principal Scientific Advisor to Government of India. Prof. Raghavan is the Chief Architect of India’s National Knowledge Network (NKN). He Chairs the Technical Advisory Committees of NKN, NOFN, and DTH – three major efforts of Government of India. Prof. Raghavan was the President of Computer Society of India and represents India in the General Assembly of the International Federation for Information Processing (IFIP). Prof. Raghavan has been recognized and awarded at National and Global level for his excellence and contribution towards the Country's growth and security. The Outstanding Alumnus awarded by Anna University and the Silver Core awarded by International federation for Information Processing, and Doctor of Science by Uttarakhand Technical University and Andhra University are very special to him. Recently, he was awarded the Techno Visionary Leadership Award by Indian Electronics and Semiconductor Association.
