1. WELCOME ALL

2. Why the need to migrate to IPv6?

3. Comparison between IPv4 and IPv6
IPv4 uses 32 bit addresses and can support 4.3 billion devices.
IPv6 uses 128 bit addresses and can support 2 to the 128th power devices

4. Understanding IPv4

5. Understanding IPv4 (Cont.)

6. Understanding IPv4 (Cont.)

7. Migration Process
Auditing the networking and other hardware devices for IPv6 compliance
Auditing the Operating Systems and Applications
Procurement of IPv6 compliant hardware and software
Transition plan
Setup of IPv6 pilot network

8. Migration Technologies
Dual Stack
Tunneling
Translation

9. Migration Technologies
Dual Stack:
A common dual stack migration strategy is to make the transition from the core to the distribution to the access layer.

10. Migration Technologies
Tunneling:
Tunnels take IPv6 packets and encapsulate them in IPv4 packets to be sent across portions of the network that haven’t yet been upgraded to IPv6.

11. Migration Technologies
Tunneling (Cont.):
Tunnel need less infrastructure
Deep packet inspection of tunnel is difficult

12. Migration Technologies
Translation:
Translation techniques perform IPv4-to-IPv6 translation (and vice versa) at a
particular layer of the protocol stack, typically the network, transport or application
layer

13. Migration Technologies
Translation (Cont.)
Unlike tunneling, which does not alter the tunneled data packet, translation
mechanisms do modify or translate IP packets commutatively between IPv4 and
IPv6.

14. Migration Technologies
Translation (Cont.)
Translation approaches are generally recommended in an environment with IPv6-
only nodes communicating with IPv4-only nodes.

15. IPV6 ROLLOUT PLANS OF SERVICE PROVIDERS

17. IPv6 Status Today in India
Major ISP TCL, Bharti, Reliance, SIFY etc in India are ready for IPv6 Services.
IPv6 Penetration in India is less than 1%
Many ISPs lack the network infrastructure to handle IPv6
Access Infrastructure not IPv6 ready
IPv6 Penetration in Broadband /Mobile Internet is Nil
Few ISP like TCL, Sify, BSNL, Bharti , TTSL have domestic peering with NIXI
No IPv6 Content available in India

18. No IPv6 Request from Customers for the following reasons
ISP still provides IPv4 Address
Customer not ready to upgrade infrastructure due to additional Capex
Lack of Training and Awareness
Need to remove legacy network and desktop assets
Lack of Low Cost IPv6 Compliant CPE Equipment.

19. Existing services transition required
Enterprise customer with multiple location (connected through leased lines or over MPLS)
Broadband (ADSL) Customers
Mobile Wireless (GSM, CDMA, 3G) customers
WiMAX Customers
ISPs who are taking bandwidth
Narrow-band Dial-up customers(No IPv6 services)
Servers, backbone and access equipment
Leased Line Customers

20. Service providers plans
PRESERVE >>>> PREPARE >>>> PROSPER
IPv6 Addressing Plan
IPv6 Routing
IPv6 Peering
IPv6 Application Servers
IPv6 Network Monitoring and Management
IPv6 support in Access Equipment
Test IPv6 Applications and Services

21. Action plan for service providers

22. Action plan for Govt. Departments

23. Action Plan For TIFR
1. Prepare an Inventory for hardware & Software for IPV6 Compliance. 2. Generate Reports based on Inventory. 3. Make the Router, Firewall, Core switch and distribution switches ready for handling IPv6 traffic. 4. Design applications which are IPv6 compliant.

24. Action Pan For TIFR (Cont.)
In the initial phase we will have to go for Dual stack configuration.
A test bed has to be configured before making anything live. Hence the immediate step should be to prepare a test bed where applications can be tested for connectivity, integrity, feasibility and most important security before putting into production.
