APPARATUS AND METHOD FOR TRAFFIC CLASSIFICATION, APPARATUS AND METHOD FOR BUILDING TRAFFIC CLASSIFICATION PROGRAM, COMPUTER READABLE MEDIA

摘要

PURPOSE: An apparatus and a method for traffic classification, an apparatus and a method for building a traffic classification program, and a recording medium read by a computer are provided to classify the traffic of applications by recognizing a pattern from images converted by standardizing the packet size and inter-arrival time of the traffic in a network relay device. CONSTITUTION: A network device comprises a traffic classification part (210) and a storage part (220). The traffic classification part calculates a representative value from characteristic information on a series of packets and classifies the data packets according to the results of determining the position of the representative value from stored images. The storage part stores map information on the images and provides the map information on the images when the traffic classification requests.
