Popularity ranking of Internet services is an important metric for network operators. Lately, Internet service identification of a given flow has become very difficult due to the rapid growth of CDNs and/or encrypted traffic, while some research works employed preceding DNS traffic as a hint. However, because of its cache mechanism, the DNS message count deviates from the actual number of flows, which can greatly degrade the ranking reliability. We propose a theoretical model for inferring the user's number of accesses per domain name by exploiting the characteristics of the DNS message count. |
