Abstract: Provided is a method for WLAN service performed by an access point (AP) in a WLAN system including the AP and a plurality of stations (STAs) each of which can associate with the AP, the method comprising: dividing frequency bandwidth of available channel into a plurality of frequency-selective subchannels; receiving, from at least some STAs (first STAs) among the plurality of STAs, CRQ (Contention Resolution reQuest) frame including a signature of the first STAs through at least some of the subchannels, the signature identifying the first STAs; identifying the first STAs using the received CRQ frame; estimating uplink channel quality of the first STAs using the received CRQ frame; allocating subchannels for each of the first STAs; and broadcasting result of subchannel allocation using CRP (Contention Resolution rePly) frame.

Abstract: The present invention relates to a network management system for analyzing Internet application traffic. An apparatus for Internet application traffic classification benchmark according to the present invention configures two or more Internet application traffic classifications in plug-in scheme to perform a benchmarking function for the performance of each Internet application traffic classification. The apparatus can provide an objective and accurate evaluation for each classification technology by aggregating various Internet application traffic classification technologies by the plug-in scheme.
