Status of Taiwan’s Campus WLAN(2007,Q3)

Total:163 Univ. and Colleges

Non Roaming 29%

In Roaming 71%

No plan for Campus WLAN 2%

Will complete Campus WLAN

in 2 years: 3%

Roaming Center

(NCHC)

Roaming Server

(Linux Red Hat/Fedora)

Firewall

OpenVPND

RADIUS Server with Proxy

( FreeRadius, SNMP enabled )

Roaming Server – Software Architecture
  • The “FreeRADIUS” implements the RADIUS protocol and uses the RADIUS-Proxy to communication with Roaming Center.
  • The “Firewall” controls the access right to Roaming Server.
  • The “OpenVPND” builds the secure tunnel between Roaming Server and Roaming Center.
  • Roaming Center uses the “SNMP” to monitor the status of Roaming Server.
