Overview• USA
– vBNS, NGI, Internet2
• CANADA– CA*net II
• Europe– TEN-34
• Asia-Pacific– APAN– APAN-KR
vBNS (I)• very high-speed Backbone Network Service
• High speed network for US Research and Education Community by 5-year agreement between NSF and MCI
• Objectives– Supporting scientific applications between Supercompute
r Centers and Research institutions
– Providing a testnet for new network technologies
vBNS (II)
• Launched in 1995.4, as IP over ATM network with OC-3(155Mbps)
• Upgraded currently to OC-12(622Mbps) and OC-48(2.4Gbps) by 2000
• A part of NGI(Next Generation Internet)
Initial interconnect for Internet2
vBNS Network Services
• Full UBR PVC mesh between IP routers
• Routing – OSPF as IGP(Interior Gateway Protocol)– BGP4 as EGP(Exterior Gateway Protocol)
• Multicast : PIM Dense-Mode
• Reserved bandwidth service(RSVP) on VBR PVCs
Internet2• Initiated by 34 universities in 1 Oct. 1996• Over 110 universities are Members with Corporat
e Partners and Affiliate Members• a project of UCAID• Goals
– Recreating a leading edge network capability– Enable a new generation of applications – Transfer of technology from I2 to Internet Community
• Interconnected through GigaPOPs UCAID : University Corporation for Advanced Internet Development
GigaPOP : Gigabit-capacity Point of Presence

Internet2
Next Generation Internet• Initiated by federal government in 10 Oct. 1996• Goals
– Develop next generation network testbed to connect universities and federal research institutes
– Promote experimentation with next generation of networking technologies
– Demonstrate a new generation of applications, which support scientific research, national security, distance education, environmental monitoring and health care
• $100M/year for 5 years divided between DoE, DoD, NASA, NSF and NIST

CA*net II• To facilitate a partnership between industry, carr
iers, Regional Advanced Networks and R&E community
• To accelerate the deployment of next-generation commercial Internet Service
• A virtual network spanning two ATM clouds: BAC and AT&T Canada

TEN-34• Trans-European Network interconnecting at
34Mbps• Develop a high-speed backbone for the academic
community in Europe• Two distinct parts in TEN-34
– A high-speed production IP network to cover immediate needs for higher speeds
– Extensive ATM network built over JAMES
JAMES : Joint ATM Experiment on European Services
APAN
• Asia-Pacific Advanced Network Consortium established in 1997.6
• Advanced networking for Asia-Pacific– Research & development for advanced application
and services– Advanced networking environment for research
community– International collaboration
