The HKUST campus network is based on a routed network topology with a high-speed switched Gigabit Ethernet campus backbone. The network backbone consists of 2 core Gigabit Enterprise Switches (Cisco Catalyst 6509) with an aggregate routing performance of up to 30 million packet per seconds. Connected to these Enterprise Switches are around 80 Edge Switches which are installed in each wiring closets with Fast Ethernet (100 Mbps) or Gigabit Ethernet (1,000 Mbps) uplinks. Edge switches are devices that provide client connectivity at the edge of the network.

These core network gears connect over 40 sub-networks throughout the campus. Mainly TCP/IP and AppleTalk network protocols are routed through the campus backbone. In general the network is designed using a distributed approach. Each subnet has its own network servers to serve all local network clients. These local servers, mainly Unix and Windows NT/2000 based, will provide name, file, print and application services.
