Research Collaborations India is effectively participating in the major international experimental programmes in Europe such as Large Hadron Collider (LHC), ITER, and others. Participation in the European Framework Programmes has been very fruitful and has enabled Indian scientists to collaborate in frontier research activities with European colleagues. Cooperat ooperatio ion with th Globa lobal Virtua irtual Re Research search Com ommu munit nities es (G (GVRCs VRCs) through through pro project jects like ike LH LHC Grid rid & EU EU-Ind IndiaGrid iaGrid gave ave Ind India ia much uch neede needed impetus mpetus for for creati creating an an e-inf nfrastru rastructure cture with thin in th the cou country try.

The EU EU-India ndiaGrid rid project, which has allowed Indian scientists to access major European and Indian Grid infrastructures exposing them to the grid technology, made significant progress in last two years.

Trend: Network Infrastructure Grid & Cloud computing has demanded deployment of an advanced network infrastructure for Research & Education to be effective Light (lambda network facility) is the response to the need for high-quality research and education. It will help create a viable economy-of-scale model for the region to reduce networking costs per country, serve as a test-bed for development of new services, and allow the R&E community to participate in international networking activities support the growth of National Research & Education Networks (NRENs), accelerate research, fuel national and regional economic growth, and aid their integration with the rest of world. Many countries today have Lambda Network Facility – an e-infrastructure Page 4 National Knowledge Network
The e-Infrastructure of India NKN is a state-of-the-art multi-gigabit pan-India network: www.nkn.in National Knowledge Network: Enabling a Paradigm Shift in Research Infrastructure And Global Science Cooperation CHAIN EU-IndiaGrid Indian Grid Certification Authority TIFR-CERN link Page 5 National Knowledge Network
How Testing of NKN was done? • Exhaustive testing was conducted – Functional Testing (ping, test route, latency, packet loss) – Sustainability Testing by HD Video-Con tests (Light weight, lossy data permitted) – End-to-End Performance & Reliability Testing using FTP data transfer for short & long periods (Heavy weight, lossless data) – Application testing • Collab-CAD connecting BARC-IGCAR-NIC • Grid Computing (DAE grid BARC-IGCAR-TIFR-VECC) Page 6 National Knowledge Network
Interconnect-Related Terms Most critical component of HPC still remains to be interconnect technology and network topology Latency: Networks: How long does it take to start sending a "message"? Measured in microseconds- startup time Round Robin Delay & Number of Hops Processors: How long does it take to output results of some operations, such as floating point add, divide etc., which are pipelined?) Bandwidth: What data rate can be sustained once the message is started? Measured in Mbytes/sec or Gbytes/sec Page 7 National Knowledge Network
Best Effort is not Good Enough … Choice for QOS - Set up optimized path - Select Level 2,3 ,4 switching - Trade-off between buffer size & Appln - Guaranteed end- to-end performance 8 Page 8 National Knowledge Network
On the Network: Big Problems! • Network Traffic Profile • Mixing Traffic • Trade of between buffer size Vs Appln ## Better Data handling methods, Innovative Algorithms in Data analytics are needed. Also high resolution data visualisation techniques & tools needed to be developed !!! 9 Page 9 National Knowledge Network
