  1. Campus Wireless Network kitenet Koji OKAMURA Research Institute for Information Technology, Kyushu University

  2. Overview of Kyushu Univ. • is located in Fukuoka City of Fukuoka Prefecture. • Population of Fukuoka City is 1.3M. • Population of Fukuoka Pref. is 5.0M. • has • 20,000 students and 10,000 staffs (faculties and etc.). • and two main big campus (hakozaki and ito) and several satellite campus (hospital, chikushi and oohashi ). • every campus are connected 10G. • uses • AS2508 and one Class B address (133.5.0.0/16).

  3. Campus of Kyushu Univ. Main Hospital 15km New Main Art Material, Energy etc

  4. Why Campus Wireless Network is necessary ? • Everyone of Kyushu Univ. want to use Internet when they come to University. • Everyone had bought and set-upped their own Wireless AP. • Only owner can use his Wireless AP even there are so many Wireless APs in campus. • Policies for Member of Kyushu Univ. and guests should be different. • Computer Center had decide to introduce Campus wide wireless network in 2006.

  5. The 1st Version (2003~2007) • Mobile IP based. • Non Standard. • 228APs • Special Driver (Software) is necessary. • The product becomes “Dis-Continue”. • No Windows Vista support.

  6. The 2nd Version (2006~ • 802.1x Base • 591 APs • APs are installed with core network when the new building is build.

  15. The current situation • every one can use Internet using Windows, Mac, iPhone, Windows Mobile…. • even guests can use Internet when they come to Kyushu Univ. based on security policy of Kyushu Univ. • Conference at Kyushu Univ.

  16. Future Works • Big segment across whole campus management/authentication Kyushu University Guest

  17. Future Works • They should be segmented. • IPv4 is used for each segment. • Virtual Router will support the routing. Authentication Management Kyushu Univ. Guest
