Goals in 2004• To help domestic ISPs to promote their network
infrastructures from IPv4 to IPv6• To construct the public networks, such as TANet and
TWAREN, with IPv6 enabled infrastructures • To integrate the domestic government, academic,
industry, and commercial IPv6 network infrastructures• To develop killer applications, such as digital A/V
contents, VoIPv6, multicasting, and grid computing on IPv6 infrastructures
• To do IPv6 technical cooperation and experience exchange with other countries
Projects in 20041. ISP IPv6 Exchange Points Construction (ASCC)2. IPv6 Digital A/V Transmission (Chunghwa
Telecomm)3. Enabling IPv6 in the Backbone of the Taiwan
Academic Network (TANet) (MOECC)4. Deployment and Promotion of IPv6 SIP VoIP on
Campuses (Computing Center, NCTU)5. TWAREN IPv6 Network Platform & Applications
Development Project (NCHC)
1. ISP IPv6 Exchange Points Construction
• To help ISPs to construct their IPv4/IPv6 transition systems
• To construct IPv6 route servers, and traffic and real-time network monitoring systems
• To construct IPv6 traffic exchange points for commercial and academic networks
• To provide peering services with 6bone and M6bone for academic, research and commercial IPv6 networks
• To provide IPv6 multicast peering services and to help peer networks to construct IPv6 multicast servers
1. ISP IPv6 Exchange Points
1. ISP IPv6 Exchange Links
• Domestic Native Links with • 8 Networks • Bandwidth 360MB
• Overseas Native Links with• 19 Networks • Bandwidth 777MB
• Links to IPv6 IXs• NSPIXP-6, StarLight, 6TAP
2. IPv6 Digital A/V Transmission
• Based on the broadband IPv6 infrastructure and A/V platform of Chunghwa Telecomm
• Using high-quality IPv6 network transmission technique and service mechanisms
• Supporting high-quality free and variety IPv6 digital contents to general users and research networks, such as TANet,TWAREN and ASCC
• Attracting more IPv4 customers to use IPv6 networks

• To construct IPv6 DNS root servers application servers and for TANet
• To provide transparent IPv6 to IPv6, IPv4 to IPv6 and IPv6 to IPv4 communications
• To provide TANet users to access IPv6 application software easily for promoting IPv6 technology effectively

3. TANET IPv4/v6 Co-existing Network
4. Deployment and Promotion of IPv6 SIP VoIP on Campuses
• To construct the campus-wide network, including NTU, NCTU, NCKU, and NSYSU, for IPv6 SIP VoIP services and promotion
• Initially, to construct the campus IPv6 SIP VoIP environment
• Then, to invite academic and ISPs to test and promote the IPv6 SIP VoIP infrastructures

• To construct TWAREN IPv6 network, then toinitiate the multicasting function
• To design a network platform to support theIPv4/IPv6 dual stack system
• Peering TWAREN with international IPv6research networks, to enhance its extendibility
• Based on this network environment, to constructeco grid and telescience grid and to promotetheir applications
