IPv6 adoption path

SLT has selected to follow below path of evolution for IPv6-ADOPTION;

1. Squeeze IPv4 usage by lean allocations to end users2. Extend IPv4 Life with CGNat3. Deploy IPv6 in Dual-Stack environment • with v4-v6 transition technologies

4. Phase out V4

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

Strategy

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

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

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

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

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

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!

Thank You!
