Research Collaborations

India is effectively participating in the major international experimental programmes in Europe such as Large Hadron Collider (LHC), ITER, and

  • thers. 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

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

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)

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

  • perations, 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

Best Effort is not Good Enough …

  • Set up optimized

path

  • Select Level 2,3

,4 switching

  • Trade-off

between buffer size & Appln

  • Guaranteed end-

to-end performance

Choice for QOS

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 !!!

Few aspects to be considered

  • Sustainable applications of common

interest such as weather/climate modeling & simulation, biodiversity, Cancer and Brain Grids, Education contents

  • Agreeing on standard data formats

and data sharing policy

  • R & D in advanced networking (100G

ICFA Report 2009 - Main Trends Accelerate: Dark

Fiber Nets, Dynamic Circuits, 40-100G

 Current generation of 10 Gbps network backbones and major Int’l links arrived

in 2002-8 in US, Europe, Japan, Korea; Now China, Brazil

 Bandwidth Growth: from 16 to 10,000X in 7 Yrs. >> Moore’s Law

 Proliferation of 10G links across the Atlantic & Pacific since 2005

 Bandwidth for LHC well above 100 Gbps in aggregate

 Rapid Spread of “Dark Fiber” and DWDM: Emergence of Continental, Nat’l,

State & Metro N X 10G “Hybrid” Networks in Many Nations

 Appearance of terrestrial 40 and 100G MAN/WAN:

 40G optical backbones in commercial and R&E networks are common  100G pilots/tests in 2009, first service deployments started

 Point-to-point “Light-paths” for HEP and “Data Intensive Science”

 Now Dynamic Circuits, and Managed Bandwidth Channels

 Technology continues to drive Performance Higher, Costs Lower

 Commoditization of GE now 10 GE ports on servers  Cheaper and faster storage ($ < 100/Tbyte); 100+ Mbyte/sec disks

Outcome from Tests

  • Tested over 6 months for short term & long

term for

  • Reliability
  • Sustainability
  • Compatibility across CISCO & Juniper
  • Successful deployment of Dark Fibers from

PSU

  • Suitability for NKN use

Conclusions

 Demand on Computations & Communication is likely to grow

exponentially in the future

 Open access to publicly funded research results and data is

now becoming a reality

  • Institutional Repositories will be important elements of the national information

infrastructure

  • Institutional repositories will need to address data issues as well as research

publications

 Establishment of National Data Centres to provide advice,

guidance and data curation services for user community will be essential

 NKN must scale well constantly in terms of users, bandwidth,

end-to-end performance and QOS to be in the race !!!
