IPv6 Growth in Taiwan
 IPv6 ASs Trend Chart in RIPE NCC

5. 5
IPv6 Challenges in CHT
 Cost Reduction
 Provisioning policy & efficiency
• IPv4/IPv6 addresses allocation is complicated
• Well-defined integrated addressing planning
 Operation management
• IPv6 services must be in parity with IPv4 services
– Routing, QoS, Network management, Billing…
 Technical knowhow efforts
• Personnel Training & Education
– Skills for IPv4+IPv6

6. 6
IPv6 Challenges in CHT
 Risk Management
 Secure IPv6 Environment
• More IPv6 Traffic, more potential IPv6 attacks
• Providing IPv6 carrier security the same as IPv4
 Contingency Plans for Rapid IPv6 Growth
• Prepare for the traffic growth from LTE

7. 7
IPv6 Challenges in CHT
 Revenue Generation Opportunities
 IP Protocol Simplification
• IPv6 to unify IP-Based network
 Network architecture flexibility
• SDN provides dynamic network architecture
– Openflow 1.3.X supports IPv6
• NFV integrates all ISP′s services
 Generic Network
• ISP can provide a general network architecture for
broadband (FTTx / ADSL) and mobile services
(3G/LTE)

8. 8
Future Work
 CHT's IPv6 Milestone：
 10% can be seen as a major protocol in the world
 Long Term Planning：
 Make strategies step by step depending on IPv6 growth
• EX:
– 2% IPv6 traffic growth => CHT can provide IPv6 service
for 10% subscribers in broadband & mobile services
 Observe the correlation between CHT′s IPv6 growth and
network capability and make a proper plan to meet the
requirement
 CHT IPv6 growth as a check point to decide the ration of
IT staff IPv6 training need
