  1. Update on Advanced Networking in Singapore APAN Meeting Busan, Aug 2003

  2. Background • International R&E networking provision through SingAREN • SingAREN Phase 1 – Nov 1997 to Mar 2001 • SingAREN Phase 2 – Apr 2001 to Sep 2003, with aim to: • Ensure continuity of R&E advanced networking requirements – SingAREN21 infrastructure • More diverse R&D activities and improved project management – Broadband21 projects

  3. SingAREN Peering Arrangements • Architecture: • Peer PVC routers • Layer 3 via BGP4 • Domestic peering: • Tertiary institutions, including NUS, NTU, SMU, TP, etc. • Research institutes, including I2R, IMCB, BII, etc. • International peering: • US - Abilene (upgraded to 155 Mbps in May 03) • Korea & Europe – TEIN (upgraded to 6 Mbps in January 03) • Malaysia – (via Satellite link between TP & USM) • Asia-Pacific – APAN (6 Mbps)

  4. Current Network Topology The SingAREN network Infrastructure comprises: (1) dedicated direct international links to APAN-Korea and the Abilene network, and (2) local connections to research and education entities via a broadband network.

  5. Network Configuration • SingAREN operates 2 PoPs – Singapore PoP & Seattle PoP • Seattle PoP aggregate and control traffic entering SingAREN’s international link • In Seattle SingAREN Connected to : • Internet 2 via Abilene (GE Connection) • Internet via NTT/Verio (OC3-POS Connection) • Other Peering Partner (Such as SIX using GE, PAIX using FE and PNWG using GE) • Singapore-to-US international link via OC3 POS (155 Mbps) [effective May 2003] • Singapore-to-APAN(Korea) link at 6 Mbps ATM VBR-nrt. [effective Jan 2003]

  6. Proposed Cost Model • Current SingAREN funding ends in September 2003 with cessation of direct funding for infrastructure • “Pay-your-own-way” Model has been implemented • Aggregation of Commodity Internet & Internet2 traffic • Term contract arrangement with network Telcos • Flexibility for R&E Organisations to join anytime • 6-monthly price review to maintain competitiveness • Advantages: • Better facilitation of Internet transit among R&E organisations • Cost effectiveness with significantly discounted rates • Better accountability of network utilization

  7. Other Activities • SingAREN Broadband 21 Projects • 10 Advanced network projects; 7 Applications project • KRAN – Kent Ridge Advanced Network • Project to set up a small optical network testbed with the aim of facilitating in the definition of a country-wide optical R&E network in Singapore (end in August 2003) • SIX – Singapore IPv6 Internet eXchange • an IPv6 based IX to allow the exchange of IPv6 traffic • ONFIG – Optical Network ConFIGuration • Multi-party project looking into R&D of optical network related devices • NII – Next-generation Info Infrastructure • Spearheaded by InfoComm Development Authority (IDA) to investigate future broadband infrastructure • BMG – Bio-Med Grid • Building the virtual community has started • NGP – National Grid Project • Funding approved for Pilot Project • Thematic Strategic Research Program (TSRP) on Grid Computing • Workshop planning for theme evaluation started • Workshop to be held on 22-23 September 2003

  8. Future Directions • Activities in life sciences & Grid computng expected to significantly increase demand for bandwidth in Singapore • How to share resources and costs for inter-REN connectivity? • Process to institutionalize SingAREN as non-profit organization initiated • Plan to complete process in 4Q03

  9. SingAREN21 The Singapore Advanced Research & Education Network http://www.singaren.net.sg/
