Update on Advanced Networking in Singapore
APAN Meeting
Busan, Aug 2003
Background
International R&E networking provision through SingAREN
SingAREN Phase 1 – Nov 1997 to Mar 2001SingAREN 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
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)
Current Network Topology

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
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
