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
