Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: A system and method are disclosed for a non-invasive scheme for application recognition using packet processing. The system and method determine the type of application based on meta-information about the packet flows, rather than on the contents of the packets. An embodiment method includes monitoring and storing, by a processor, direction values, timing values and size values of a sequence of packets for each of a plurality of application protocol types. The direction values are discrete, and the timing and size values are continuous. The method further includes training a hidden Markov model (HMM) for each of the application protocol types using a HMM training algorithm on the direction, timing and size values.
