Internet Protocol
Transports a datagram from source host to destination, possibly via several intermediate nodes (“routers”)
Service is: Unreliable: Losses, duplicates, out-of-order delivery Best effort: Packets not discarded capriciously, delivery
failure not necessarily reported Connectionless: Each packet is treated independently
What is an IP address?
• Each host on a TCP/IP network is uniquely identified at the IP layer with an address.
• An Internet Protocol (IP) address specifies the location of a host or client on the Internet.
• The IP address is also known as Protocol address
• The IPv4 address is 32 bits long• The IPv6 address is 128 bit long
Problems of IPv4
Addressing problem Routing Crisis End to End problem Security Mobility Performance Cost
1. Larger address space2. Global reachability3. Flexibility4. Auto-configuration5. Aggregation6. Multi-homing7. Efficient Routing8. Scalability9. Easy Mobility10.Better security
IPv6 Features
Global ReachabilityFrom 32 bits to 128 bits addresses enables:
– Global reachability:
• No hidden networks, hosts
• All hosts can be reachable and be "servers"

Suggested Pilot Projects in Greenfield Applications Rural Emergency Healthcare System Telemedicine Distance Education Power Generation and Distribution Logistics and Supply Chain
Different Ministries, Government Departments and Organizations in Private Sector can come forward to Work on these and similar Pilot
Projects. 29

Deficiencies in Today’s – Rural Emergency Healthcare scenario(Communication only by Phone)
•Vital sign information sent on phone - Blood pressure, ECG, Temperature .. Etc.
•Doctor lacks the ability to see the patient’s visual condition
•Doctor provides Offline Healthcare on phone
•Ambulances manually called and guided over phone to destination

Benefits – IPv6 Rural Emergency Healthcare scenario
Real Time Patient Vital sign information collected by Bio Sensors– Blood pressure, ECG, Temperature .. Etc,
Patient’s condition is seen in real time Video by Doctor - More effective diagnosis and advice

Indian Electricity Scenario
Power Supply Position (MW)
Demand Supplied Shortage %
2005-06 93255 81792 12.3%
2006-07 100715 86818 13.8%
2007-08 108866 90793 16.6%
2008-09 109809 96685 12%
AT&C (Aggregate Technical & Commercial Losses) ~ 33%
Objectives - APDRP (Accelerated Power Development and Reform Programme
of the GoI – Funded through PFC)
Sustained Loss Reduction
Reliable and Automated systems for collection of accurate Base Line Data
Adopting IT for energy accounting
Today’s Scenario
Electricity grid is “DUMB"
Workers have to walk from house to house to read the electricity meter
Utilities have no clue of power outage until customers call to complain.
Tomorrow’s Scenario ?The electricity grid is “SMART” enough for –
Remote collection of data – fully sensor based network
Automatic load balancing, DSM and transfer of power from one region
to another
Automatic detection of outages
Flexible metering
What will make it possible ? IPv6
Using IPv6 for Smart grid Services
Advanced Metering Infrastructure
Automatic meter Reading using sensors
Business Analysis Analyze usage data to make decisions
Energy Management Services
Grid monitoring and management
Demand Side management Remote management of energy demand, Load balancing
Distribution automation Optimize performance of Transmission and Distribution assets
Remote equipment Monitoring
Ease of fault detection, maintenance
Telecommunications Can be provided as a service using the power line infrastructure
IPv6 in RailwaysHow can Railways benefit from IPv6 deployment ?
Railways handles India’s largest supply chain consisting of wagons, bogies, engines, processing centers, point of sale
terminals , millions of parcel objects each day

Addressability
Scalable Internet Platform
Connectivity
Service Automation
Vision for Railways / Railtel
Highly optimized supply chain based on IP technology (IPv6)
Very large scale telemetry and sensor network enhancing railway safety (enabled by IPv6)
Railtel as an ISP (Broadband subscribers on IPv6)
Advantages of NCW
• Power is increasingly derived from information sharing, information access and speed
• Networked forces can be smaller in size
When the forces are well connected they can spread out over a larger area
thus reducing the chances of fatal incidents wiping out the entire troop at
the same time
•When one unit gets into trouble other units can quickly come to its aid
• Difficult for enemy to attack a spread out formation
• Fewer troops, lesser equipment – cheaper warfare
• Sensor based networks – on-site analysis of intelligence data obtained through sensors – quicker decision making in the battlefield
