IT network

With 542 wifi access points, the entire campus, from the Academia Building to the Faculty Club and from the park around the Cobbenhagen Building to the parking lots behind the Tias Building, is covered by a wireless network. At any moment on any given day, about 7,000 appliances are connected to this wireless network, surging to 10,000 appliances at peak times. In addition, there is a glass fiber network with 18,825 outlets, 9,239 of those being active in 2017. The University’s Internet connection has a ten-gigabytes-per-second capacity. The University network comprises six physical routers, two VPN servers, two Application Delivery Controllers and four firewalls. As this network is a regular target for attacks, so-called Distributed Denial-of-Service (DDoS) attacks, the University has installed dedicated network equipment, blocking about a thousand of such attacks a day.

Though considered old-fashioned by some, email still remains one of the most important services. A ground-breaking technology in the nineties, it is now a commonplace medium with over a million emails being received a day. Some 835,200 of these, for that matter, are intercepted because they are spam. About 200,000 emails are delivered to user inboxes every day, 140,000 to students and 60,000 to staff. All members of staff together send about 20,000 emails a day.
