1. National Knowledge Network Overview

2. Experience life with 1000000000 bps
9th April 2009

3. Enable, Encourage, Empower, Enrich
Need of the Hour
Need a single infrastructure that supports multitude of applications in a secure manner
Provide a scalable mechanism
Load balance traffic to utilize network bandwidth efficiently
Allow core routers/networking devices to switch packets based on some simplified header
QoS aware network
Scalable/ Adaptable/ Available (24X7X365)
Enable, Encourage, Empower, Enrich

9. Challenges in Initial Phase Delivery
TECHNOLOGY
IP Numbering Schema,
Multi-Homing
Hardware compatibility
IPv6 addresses from APNIC
Manageable for short time….
MIND SET
Why Should I change My Setup
Will the change that we make are permanent.
Multiple Scheme
OPERATIONAL
Complexity in existing Network
Multiple Networks in Institute
No single point of contact in many cases
Reluctance to Change
