4. IPv6 adoption path
SLT has selected to follow below path of evolution for
IPv6-ADOPTION;
1. Squeeze IPv4 usage by lean allocations to end users
2. Extend IPv4 Life with CGNat
3. Deploy IPv6 in Dual-Stack environment
• with v4-v6 transition technologies
4. Phase out V4

5. IPv6 Milestones
• IPv6 assignment March-2008
• Enable Dual Stack in ISP Network June-2008
• First international peering established Aug-2008
• DNS, Web, Email trials 2008
• First IPv6 accessible web site launch 2008
• Tunnel services (manual) trials 2008
• Establish SLT IPv6 Task Force 2008
• Network and Systems audit 2008 onwards
• First customer connected Oct-2008
• ADSL CPEs requirement 2010
• National Working Group for IPv6 2011
• Local Internet Exchange IPv6 peering 2012
• SLT corporate site on IPv6 2014
• CGNAT implementation 2014
• Identify and resolve Policy Control issues 2014-2015
in Dual-Stack environment
• ADSL broadband testing 2012, 2015
• Finalize transition strategy for ADSL, LTE 2015
• Deploy for Residential Users 2016

6. Strategy
 Adopt Early and Lead
 Learn and Develop Skills
 Implement Gradually
 Enforce Compliance for New Investments
 Evaluate and Upgrade with Minimum Cost

7. Challenges
EXTERNAL
 Content
- Un-supported Applications
 Customers
- Corporate segments
 No demand pull
 End user network elements and applications not ready
 Knowledge gap
- Consumer
 No demand pull
 Policy Enforcement (PCEF) issues
 Un-availability of affordable IPv6 ready CPEs
 Lackluster Regulatory Involvement/Demand

8. Challenges
INTERNAL
 Focus from the top
 Broadband Policy Control challenges in Dual Stack environment
 Training and Development
 Transition Technologies
 Upgrade Existing Infrastructure
 Technology Readiness of NEW systems
 Log retention and data analysis
 End-to-End performance issues with V6
 Network Management and Monitoring Overheads

9. Strengths
EXTERNAL
 Readiness of International peering/transit for dual stack
 Facilitation for training and knowledge sharing
 Ex: ISOC, APNIC, SANOG, APRICOT, APT
 Network, OS, Software Readiness
INTERNAL
 Enthusiasm and Leadership of Individuals
 Early adoption and planning
 Formation of Internal Task Force
 Learning culture & facilitation of same
 Compatibility/Upgradability of majority of network elements/systems

10. Costs
 IPv6 specific infrastructure investments
 Most network and systems capabilities available via software
upgrades
 IPv6 is mandatary for new network elements/systems/upgrades
 IPv6 Transition Capabilities – Delivered bundled with CGNAT / Load
Balancers
 Training and Development
 Cost to sustain IPv4 growth – CGNAT

11. Message
 IPv6 just allows the growth to continue!
 IPv6 is not necessarily an expensive affair!
 Learn from others experiences!
 Identify your unique strategy!
 Adopt early and migrate gradually!
