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

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
