Abstract
The invention relates to a method and a system for detecting a single data flow in an aggregate packet data flow and identifying the application generating the single data flow, this single data flow being divided into messages, each message comprising a plurality of blocks, each block (g) having n bits for identifying 2block values (i). The method comprises the steps of providing, for each block value (i), an expected frequency value (E), measuring, for a predefined number (G) of blocks (g), the values Formula (I) of frequency with which each block (g) identifies each block value (i) so as to obtain a plurality of measured frequency values Formula (I), processing, for each block (g), the measured frequency values Formula (I) and the expected frequency values (E) in order to generate a frequency deviation value Formula (II) representative of the deviation of the measured frequency values Formula (I) with respect to the expected frequency values (E), and processing the frequency deviation values Formula (II) generated for each block (g) with at least one frequency deviation threshold value (χ) in order to detect the single data flow and identify the application generating said single data flow.
