The Dartmouth College campus has over 190 buildings on 200 acres. Dartmouth College has about 5500 students and 1200 faculty, and during our study there were approximately 3200-3300 undergraduates on campus. Students are required to own a computer, and most purchase a computer through the campus computer store. Wireless laptops increasingly dominate those purchases, making up 45% of the total in 2000, 70% in 2001, 88% in 2002, and 97% in 2003. Assuming that students obtaining computers elsewhere choose laptops in the same proportion, we estimate that over 75% of the undergraduates owned laptops at the time of our study.
- network configuration
-
476 Cisco 802.11b access points (APs) were installed in 2001 to cover most of the campus. Since then, APs have been added to increase coverage and to cover new construction, and there are currently 566 APs. The compact nature of the campus means that the signal range of interior APs extends to cover most of the campus' outdoor areas. All APs share the same SSID, allowing wireless clients to roam seamlessly between APs. On the other hand, a building's APs are connected to the building's existing subnet. The 188 buildings with wireless coverage span 115 subnets, so clients roaming between buildings may be forced to obtain new IP addresses. Clients obtain IP addresses using DHCP (lease times were 6 or 12 hours at different points in the trace).
- data collection methodology
-
We used three techniques: syslog events, SNMP polls, and network sniffers (tcpdump). We also derived movement history data from the syslog data.
- sanitization
-
All data has been sanitized to protect the privacy of our users. We have resanitized the data (2004-11-08) so that there is a consistent MAC address mapping and a consistent IP address mapping across all of the traces. In other words, the sanitized IP address 111.222.333.444 will correspond to the same raw IP address in all of our traces. Similarly, the sanitized MAC address aa:bb:cc:dd:ee:ff will always correspond to the same raw MAC address in all of our traces. Note that these may not represent the same physical device, due to DHCP, MAC spoofing, etc.
This dataset contains the following 4 tracesets:
