1. Singapore Open Exchange (www.sox.net.sg)

2. Current Situation Network Layer-3 –STIX in Singapore for more than 5 years –Starhub IX and other commercial transit providers/ISPs started operation about 2 years ago –Exchange traffic via circuits terminated in ISP router at Layer-3 Network Layer-2 –ATM exchange points eg. 1-Net –Private peering via ATM PVCs –Presents scalability issues; lacks peering infrastructure No neutral IXP at Layer-2 in Spore

3. Singapore Open IXP (SOX) Project Proposal to create the first neutral public IXP Open to all ISP/IXPs (both local and foreign), IDCs, Content Providers, Business Parks, etc Interconnects with non-commercial networks (SingAREN, NUSNET, MOEnet, Biopolis, etc) Aims/Motivations: –Localising traffic –Lowering transit costs –Neutral community approach –Landing point for foreign IP networks –Testbed for IPv6, IP multicast deployments or other new IP infrastructure technology –Provision of Value Added Services for smaller ISPs (Akamai, Nomimum GNS, Web Proxy peering caches, etc)

4. SOX Roles Ensure operational quality Promote bilateral and multilateral peering Promote expansion of IXP members Training and experience building Develop and deliver new service models

5. Asia Pacific IXP Infrastructure Several initiatives to develop regional IXP infrastructure (e-ASEAN task force, ITU, etc) Abundant fibre capacities present in AP region with new cable networks C2C, APCN2, etc To improve connectivity among commercial and R&E networks in AP region Avoids US-Centric routing, for example Singapore (SingAREN) to China (CERNET) routes via Chicago, likewise for SingAREN to APAN-JP Government agencies & industry need to work together to develop AP IXP infrastructure Interested parties include: China MII, SOX, Ausbone

6. Architecture

7. Configuration Cisco Catalyst 6500 Ethernet switch 10/100/1000 Mbps switch ports Cisco 5505 router for ATM-Ethernet Bridging Primary segment/VLAN for public peering Other segments/VLANs for IPv6, and IPv4 multicast, private peering Space for partners to co-locate their routing equipment

8. Operations Infocomm Development Authority of Singapore (iDA) licensed Services-Based Operator (SBO) Cost minimised as part of community effort to encourage peering among ISPs Members only need to provide own backhaul Connectivity via any FBO or leased circuit provider (SingTel and Starhub) 1-Net ATM PVCs, and ATM-to-Ethernet bridging provided

9. SOX IPv6 Objectives –To introduce operational IPv6 service, and to facilitate the connectivity and deployment of IPv6 networks in Singapore –To operate IPv6 exchange point, and to interconnect with other IPv6 backbones around the world –To learn from these early deployment exercises about the efforts/technologies needed for transiting from IPv4 to IPv6, i.e migration issues –To lay the foundation for IPv6 commercialisation, and to provide a testbed for IPv6 applications

10. Singapore IPv6 History Started in NUS IRDU in 1996; first ASEAN country to be connected to 6Bone. Allocated 6Bone address block: 3ffe:1600::/24 In 1999 SingAREN allocated production address block: 2001:0208::/35 (Currently, the only available IPv6 production address block in Singapore) Connected to 6Tap and 6NGIX, etc.
