About the Networks Division

  Copyright: © IT Center

The Networks division is responsible for the network technology infrastructure at RWTH Aachen University. We connect all of the approximately 300 buildings to the RWTH network via fiber optic cable. For this purpose, we manage approx. 6,000 routers and switches and approx. 4,000 WLAN access points, which provide access to the RWTH network and the Internet for students and employees. The connection to the Internet is currently realized with a bandwidth of 200 GBit/s (200,000 MBit/s). In addition, we operate several telephone systems with about 12,000 users, several firewall systems and IT security applications, and offer a variety of other services in the network area.

We regularly develop software to manage and control this amount of devices and their configurations. In doing so, we provide users with portals in which, for example, changes can be made to the devices or the configuration can be adjusted automatically. We try to automate as many use cases as possible via web applications, so that both errors are avoided and time is saved.
