  1. TERENA Networking Conference 2000Lisbon, 22-25 May broadband_connection@home for students and employees Tom Koppen director computing center

  2. And now something totally different • Different accent • Not a technical expert • Case study on home connection for students

  3. University of Twente

  4. University of Twente

  5. University of Twente • 2000 students living on campus • 4000 students living in town • 2500 staff living in town

  6. University of Twente • technical and social studies • telematics, chip technology, process engineering, biomedical engineering educational technology

  7. The network on campus • Within buildings: switched Fast Ethernet • Between buildings:  Gigabit Ethernet • SURFnet: • 1994: 4 Mbps • 1997: 34 Mbps • 1999: 155 Mbps • 2000: 1 Gbps • 2002: 20 Gbps

  8. Why connection at home? • “ICT in education” • Intranet • Internet • File serving • Communication • Education free of time • Education free of place

  9. Why broadband connection? • Course Management Systems • Streaming video • Multicast • Videoconferencing • Collaborative workspace

  10. 1992: dial back • Own modem pool • For file-transfer and internal e-mail • 14.4 kbps, later 28.8 kbps • In the beginning: free of charge • Later: 300 minutes/month free • Results: • Number of accounts slowly growing • Users want to be “always on”

  11. 1994: CAMPUSnet • all 2000 student rooms on campus • 10 Mbps shared Ethernet • Fee: € 7 per month • Also: free e-mail account for all students • Result: from 50 % subscription  100 %

  12. 1996: ISDN • Faster: 64 or 128 kbps • Phone calls possible while surfing • More used by staff then by students

  13. 1998: Dial-in • Special contract with cable company • PSTN and ISDN • Free of charge (except phone pulses) • Local phone tariff everywhere in NL • Possible by competition in telecom world • All students and staff an account

  14. 1999: update CAMPUSnet • 50 hubs replaced by switches • Faster:10 Mbps shared  100 Mbps switched • Safer: no sniffling anymore • Paid by raising fee from € 7 to € 10 • Conclusion: once you possess the localloop, updating the technology is affordable.

  15. April 2000: cable modems • Special arrangement with cable company • Faster: maximum 0.5 Mbps • Authentication by UT • Fixed IP-numbers: intranet access • At last a flat fee: € 19 • Sharing the connection permitted

  16. July 2000: ADSL • Access Pilot with GigaSURF • Partner: datacom company Casene • Concentrators in 6 cities in the region • Minimum 2 Mbps  8 Mbps • Flat fee: € 36 • Results: earlier at our disposal, much more bandwidth, more certainty, a lot cheaper.

  17. Menu à la carte

  18. 200X: wireless • Wireless LAN’s • GPRS • UMTS

  19. Internet traffic during the day Twente Big city

  20. Prognosis

  21. How to lower costs and improve quality • The telco only for the local loop • To be done within university: • Authentication • Access to Internet • E-mail and other network services • Helpdesk • Administration and billing • Keep administration simple

  22. Conclusion The connections to the homes commercial ISP’s offer are not fast enough for a reasonable price. Universities should take responsibility for broadband Internet access of their students, if they have any ambition with “ICT in education”.
