2. 2 Agenda  Chunghwa Telecom Profile  IPv6 Readiness in Taiwan  IPv6 Challenges in Chunghwa Telecom  Future work

3. 3 Chunghwa Telecom Profile An Integrated telecom operator Capital : US$2.6 billion Annual Revenue 2013 US$7.6 billion Employees: 24,155 (2014.04.08) Shareholding Structure ( as of Mar. 28, 2014 ) Listed in TSE (2412) Oct. 2000 Listed in NYSE (CHT) July 2003 Rate: USD 1 = NTD 30 Established TSE ADR privatized 1996.7.1 2000.10.27 2003.7 2005.8.12 DGT 1943.6.12 Subscriber Numbers in Chunghwa Telecom’s Major Services Broadband Service (FTTx/xDSL) 4,545,214 Mobile Service (2G/3G/4G) 10,966,050 CHT ： Chunghwa Telecom

4. 4 IPv6 Growth in Taiwan  IPv6 ASs Trend Chart in RIPE NCC

5. 5 IPv6 Challenges in CHT  Cost Reduction  P rovisioning 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
