Network Infrastructure

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  Singapore-US link  Singapore-Korea link

R&D Projects

Network R&D Projects  10 Network Related Projects  Service Creation in Broadband & Wireless N/W  Multi-protocol Lambda Switching for Optical N/W  Managing DiffServ on QBONE  Measurement-based Admission Ctrl for DiffServ  Process-Oriented Simulation for Hi-speed Network  TDMA-based Satellite Network  Multicast QoS  QoS Routing Protocol  Advanced Internet POP Architecture & Services  Dynamic Transport Layer Protocols

Application R&D Projects  7 Application Projects  Digital Library Infrastructure for Distributed Geospatial Data  Distributed Simulation: Scalability, Interoperability and Application  High speed Information Retrieval, Processing & Management  Distributed E-Commerce Agents on High Speed Networks  Highly Scalable Video Codec  Virtual Reality Interface for Web-based Remote Experimentation  Packet Voice over Non-QoS Network

Optical Network Project

Kent Ridge Advanced Network  Campus-wide optical network testbed for grid technologies and research  Inter-faculty, research institute collaborative R&D  Funded by A*STAR  18-month project focus on:  optical networking, layer-2 networking  grid computing middleware  Network vendor participation

Production Network – IP over RPR

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  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 IPv6 Project

Proposed Singapore IPv6 Internet Exchange (SIX)

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
