  • Method for data packet classification in a data communications network
    Patent number: 8472446
    Abstract: The present invention pertains to a method for performing specific data forwarding actions depending on the nature of data traffic comprising data packets, which method comprises the steps of:—receiving incoming data traffic of a specific nature, belonging to at least a specific class among a number of pre-defined classes, step 201—classifying the data traffic by determining the nature of the data traffic, provided by a process of inspecting values of a plurality of selected header field(s) of an address space of a data packet, said process providing an input key, step 202, and comprising the step of compressing the rules in the classifier to a list of compressed rules such that the number of bits involved in classification is reduced, step 203, further selecting a first matching class from an ordered list of n rules that identify each class, wherein each rule comprises D fields, step 204 and a preprocessing algorithm for building a decision tree based on the structure of the classifier, said preprocessing al
