The backbone technologies have been changed from FDDI to ATM (Asynchronous Transfer Mode) and from ATM to Gigabit Ethernet over these years. The whole campus, including classrooms, student hostels, teaching blocks, academic and administrative buildings, are connected to the University Campus Backbone Network via high speed 10 Gigabit or Gigabit Ethernet links.
The fast speed enables teaching videos, seminars, and conferences can be televised - live or in recorded modes - to and from different locations on campus via video severs installed at the Centre.
2.1 ResNet
The ResNet , Residence Network, has been available since Jan 20, 1997. The ResNet connection from each hostel to the Campus Network Backbone is a 1000Mbps Gigabit Ethernet link and each user enjoys up to 100Mbps connection speed, with 10/100BaseT technology, for his/her access to the Campus Network and the Internet.
2.2
ClassNet
Starting from September 1998, we can get access to the internet at lecture theatres, classrooms, libraries and public areas via a gigabit or 100M ClassNet connection port. It employs Virtual Private Network (VPN) technology which ensures only authorized users can access the network. The ClassNet connection is similar to the ResNet connection, which provides high-performance communications for all ClassNet users.
2.3 Wireless
LAN
Since September 2000, most of the open areas on the campus have been equipped with 802.11b wireless LAN access points. Through wireless LAN connections, staff and students can move with their laptops freely in Wi-Fi covered areas for accessing the campus network and the Internet. Wireless LAN connects to the Internet through ClassNet.
2.4 CUHKNet
To access restricted sites like the University Library resources, CUHK Newsgroup, etc OFF campus, simply through your commercial broadband service provider using a virtual private network (VPN) connection.
2.5 Remote
Departments
Remote departmental LANs such as Prince of Wales Hospital, Taipo Hospital, Lek Yuen Health Centre, Eye Hospital, School of Continuous Studies, School of Law and MBA Programme are connected to Backbone through Metro Ethernet link, and remote routers.
