Apparatus for detecting a periodicity, a method thereof and a recording medium thereof

Abstract

A device for detecting periodicity includes a collection unit for collecting or capturing a plurality of packets for mutually transceiving between a plurality of wireless terminal and a plurality of servers through a communication network; a preprocessing unit for connecting the packets and packet collection or capture time information collected or captured by the collection unit to each wireless terminals IP and servers IP/PORT and mapping the connected them; a modeling processing unit for processing at least one data modeling and grouping for each packet generation patterns, for the mapped packets; a pattern detection unit for detecting similar data models within the margin of defined error as repetition generation pattern types by mutual lengths between a plurality of data models grouped for each packet generation pattern; and a periodicity detection unit for determining periodic section when the detected repetition generation pattern types are successively generated above n times and the sections successively generated above n times occupy above predetermined rate for total sections.
