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

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

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
