dc.description.abstractThis thesis presents a characterization study of DNS traffic within the University of Calgary edge network. The traffic analysis is based on a one-week period of observation (from September 3, 2018 to September 9, 2018). We study the two directions (outbound and inbound) of the DNS traffic, representing the two roles that the campus plays in the DNS architecture, namely a user and a service provider. We selectively analyzed the traffic of a few campus DNS servers. In addition, we also examine several DNS-related anomalies. The measurement results show that a significant proportion of DNS messages come from misconfigurations or answers with short TTLs, which can both be improved to reduce the DNS traffic volume.en_US
