SingAREN21 Network Configuration
Network Configuration
:
 ILS bandwidth of 7 Mbps (CBR) and 25 Mbps (VBR-nrt).
 SingAREN has a PoP in San Jose to aggregate all its US traffic.
 PoP provides control over the amount and type of in-bound traffic entering SingAREN’s 32Mbps
international link.
 US local connections to StarTAP & Abilene at 45 Mbps & 155 Mbps respectively.
Network Utilization

IPv6 Project
IPv6 Configuration
 International IPv6 connectivity
- 6TAP, Abilene, Korea NGIX, MIMOS
 IPv6 Architecture
- using a dual stack Cisco 7505 router running IOS 12.2T
 Peering
- SingAREN provides peering services using BGP4+.
- Native IPv6 peers: 6TAP, Abilene, APAN (Korea)
- Tunnelled IPv6 peers: 6NGIX, MIMOS, ICR, SoC
 IPv6 address
- assigned with 3FFE:1600::/24 (6BONE) & 2001:208::/35 (global)
- pseudo TLA and sub TLA for Singapore.
IPv6 Configuration
IPv6 Project
 To introduce and spearhead the deployment of IPv6 technologies.
 Key objectives:
 Provide native IPv6 internet connectivity and service to the IPv6
community by deploying an IPv6 exchange point.
 Gain IPv6 deployment experience by deploying an IPv6 infrastructure
and services.
 Design and implement IPv6 transition service for the integration of IPv4
and IPv6 networks.
 Develop an IPv6 deployment model for campus network and service
provider.
IPv6 Project
IPv6 Project
 Deployment of Singapore IPv6 Internet Exchange (SIX)
 Provide connectivity to IPv6 internet
 Interconnect other IPv6 nodes.
 Existing tunneled nodes can migrate to native IPv6 connection
 New IPv6 nodes interconnect at the SIX via tunneling or direct IPv6
connection.
 SingAREN assign IPv6 address to participating nodes.
 Nodes can participate/contribute to the development/ deployment/testing
of IPv6 technologies/solutions.
 Deployment of IPv6 network and services
 Internet services (DNS, web, ftp, etc) to service the IPv6 community at
SIX
Proposed Singapore IPv6 Internet Exchange (SIX)
Future Directions
Future Directions
 Role of SingAREN as R&E network service provider
 Rising need for R&E bandwidth – cheaper bandwidth?
 Separation of experimental facility from more reliable
production facility
 Activities in life sciences will significantly increase
demand for bandwidth
 Challenges and opportunities for optical networks
 Challenges and opportunities with seamless wireless
connectivity
