  1. Internet Test-beds in Tsinghua University Jilong Wang/2008-08-25

  2. Test-bed Resources • TUNET, a campus network • CERNET Backbone • CERNET2 Backbone • CNGI-6IX • NSFCNET, IPv6-CJ, 863 test-bed, wireless, 6planetlab, ……

  3. TUNET • Since 1988 • 4124c*km fiber network • 10G Backbone, IPv4/IPv6 Dual Stack • 2G Internet bandwidth • 310 buildings, 60,000 ethernet ports 100Mb 1Gb TUNET Backbone (10GE) 1~10Gb Internet 1Gb 10~54Mb

  4. CERNET

  5. CNGI-CERNET2

  6. CNGI-6IX

  7. NSFCNET

  8. IPv6-CJ

  9. 863-testbed

  10. WiFi/WiMax and SIP based IPv6 Mobile Communication WLAN 单模手机/PDA 校园无线AP的部署 WLAN手机移动通信 校园无线网络覆盖 无线接入的IPTV/VOD 无线接入校园网方式

  11. 6PlanetLab

  12. NOC

  13. Problems • Test network does not allow on-demand experiment in fact • Commodity network can also support research activities in some way • Test system, although flexible, is only a simulation or emulation platform

  14. Design of DRAGON-Lab • Integrate resources together for dedicated research purpose • One-Net, part of internet(as24575), high performance interconnections with trial and commodity networks. Connect partner’s lab by VPN • TRC, Integrated traffic study center • BGP-Grid, experiment on commodity network • GPERF, Global performance measurement • DRAGON-Lab, distance lab

  15. Distance and visual Lab

  16. GPERF

  17. TRC

  18. BGP-Grid

  19. Remarks • Simple • Simple to build, operate and use • Dedicated • Doing everything is doing nothing • Cooperation • It is hard to make exciting things by one side

  20. Thanks!
