ADSL userADSL(Dynamic IP)

ADSL (Fix IP)

•Broadband IPv6

- 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, …

•IPv6 over ADSL

•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

•Mobile IPv6 applying on ADSL

- Dynamic ADSL users could roam to different ISPs

- Save the tunnel overhead of VPN or VPDN

HiNet

Other ISPs

Initial traffic only passes through ISPs

HiNet-User in other ISP domain

Subsequent traffic direct to Care-of-address Home

Agent

Holds care-of-address of HiNet-User in other ISPs

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
