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

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

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)

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
