The Princeton University Department of Computer Science has hundreds of PC/workstations running a variety of operating systems including Linux, Microsoft Windows, Mac OS, and Solaris. (A total of 2100 IP addresses.) Every room in the building is wired with multiple Category 5/5e UTP ports, single-mode fiber, multimode fiber, and RG6 coaxial cable. Networking is supported by a high-speed core switch with an aggregate switching bandwidth of 480 Gb/sec. Typically, servers are connected via gigabit Ethernet and user PC/workstations are connected via switched 100 Mb/sec Ethernet. The department has a 1 Gb/sec connection to the Internet.
The department supports remote users via the Internet, ADSL, and PPP. The entire building and some outlying areas are covered by the department's 802.11a/b/g wireless network. The department infrastructure and users are protected by firewalls, e-mail virus/spam scanners, and an IDS system. The general purpose computing facilities include Sun Solaris (Sparc) and Linux (x86) servers as well as a Linux cluster. The Linux cluster includes 80 processing cores and 160 gigabytes of memory in 20 compute nodes. There are public Sun Ray terminals and public printers located throughout the building. The department has approximately 700 users that share 23.5 terabytes of disk space on multiple fileservers.
