Abstract
Systems and methods for identifying sequences of encrypted packets that carry files between clients and application servers, and for estimating the sizes of these files. A traffic-monitoring system searches the traffic for connections that appear to carry file content. The system estimates the number of files that were transferred over the connection. Next, the system estimates the respective sizes of one or more of the files that were transferred over the connection. To perform this estimation, the system first 'peels away' as many lower-level protocol headers as possible from each of the packets that carries part of the file, and identifies the size that is specified in the lowest-level payload that remains. Next, the system tallies the specified sizes. Finally, the system reduces the packet-size tally to account for an estimated overhead due to the encryption of the packets.
