Taiwan on Internet--an early bird in Asia

1990 --Taiwan Academic Network (TANet), funded by the MoE, first linked up to the Internet at JvcNet in Princeton

Quickly became heavy users. Consistently ranked among top 12 when NSFnet was keeping traffic counts

Congestion a constant problem despite frequent upgrades at prohibitive cost

1997~98 -- Spurred by the NGI initiatives of the US and Canada, the NSC collaborated with the NSF, became a HPIIS partner and installed TANet2 as an advanced network for research

Early PlanningEarly Planning A tripartite partnership was formed to lease a DS3 for

the trans-Pacific link (NSC-MoE-Academia Sinica)

­ The link is a costly venture at US$10 m/yr for 3 yrs.

­ A third of the bandwidth (15 Mbps) was allocated for TANet2 for connecting to vBNS via STARTAP

­ Application projects waiting to ride on the new network covered 33 topic areas, from 22 institutions in Taiwan and 42 institutions in the US

Peering with vBNS established in November ’98 Inaugural for the DS3 held December 22, 1998

Domestic Implementation

• May 1, 1999 – construction of domestic infrastructure completed and began operation

• The National Center for High-performance Computing was charged with management. Funding provided for circuit cost but not for additional personnel

• 11 POPs engaged to assist with services• Network Operation Center outsourced to Asia-

Pacific Online

TANet2 and TANet

• No kinship but often share common grounds• TANet2 is funded by the NSC whereas TANet by

the Ministry of Education• TANet2 serves the research community whereas

TANet caters to education, from K-12 to higher education

• Acts as symbiotic body in leasing costly circuits – by pooling funds when pricing schedule befits such action

Promotion & Outreach• Web site built: http://www.tanet2.net.tw

• Participated in demonstration exhibits at SC’98 (iGrid), SC’99, INET 2000 (iGrid2000), SC2000

• Workshops held: NSC-NRC (3/’99), NSC-NSF (6/’99), TANet2 Day (4/’00), NRC-NSC (6/’00)

• Liaison role--provides scientists with guidelines for international collaboration

• 46 institutions connected to TANet2, out of 61 approved

8

Services and In-house Research

• Multicast service provided to 10 universities• MRTG, video conferencing• Looking Glass server• Net flow--dynamic graphical display• Connectivity -- status analysis• International connectivity testing -- with NIHnet of the National Institutes of Health

Bandwidth Expansion

• Upgrade of domestic backbone done twice this year – February and October, 2000– partnership with MOE– economic use of bandwidth– two-star configuration

• Link to STARTAP upgraded to 30 Mbps in October, 2000

National Telecomm Program

• Initiated by National Science Council in May 1998

• For broadband Internet & wireless communications­• 400 million US dollars for five years

• Joint research efforts of CCL (ITRI), TL and III

• Eight universities also participated, in addition to

industry effort

• Deployment carried out by the NCHC at 420,000

• Began operation in mid 1999, with NOC at NCHC
