•Broadband IPv6
IPng
- ADSL could be a chance for IPv6 migration and promotion !
- Game, VoD, VoIP, MP3, High Quality Streaming Services, …
• Find out the way of the IPv6 solution for mass ADSL customers
- Push ADSL device venders to have IPv6 boxes , e.g. BRAS with IPv6
support, CPE-based Native IPv6 ATU-R, Dual-stack IPv6 ATU-R, …
•Build a plentiful IPv6 content Network
We are planning to …
 Strengthen the content for IPv6 network
- Free and interesting contents to attract users surfing on IPv6 network
- Content including Video on demand, Live show, Audio, … for IPv6 users
 Try Multicast on native IPv6 network
- Multicast is the IPv6 design feature
- Make used of the existing IPv6 multi-media services to try
- Try to setup a IPv6 content delivery network

- Combine IPv6 DNS and IPv6 Home network
- Study easy naming and registering for the assigned home network
- Build up the Native IPv6 DNS

•Mobile IPv6 applying on ADSL
- Dynamic ADSL users could roam to different ISPs
- Save the tunnel overhead of VPN or VPDN

In this year, we are planning to …
•Expand HiNet IPv6 backbone bandwidth
•Expand HiNet IPv6 international bandwidth
•Adopting more high-level routers(now only Cisco 4500, 3600, 7500)
•Increase HiNet IPv6 POPs (now 6 POPs)
•Try new IPv6 network technology and mechanism
Thank you for the attention
