Abstract

The present invention provides a method and a device for classifying data frames. The method is typically carried out by a communication device in a wireless network with quality of service capability. It comprises the step (1002) of comparing data in a frame to data in a plurality of classifier entries, wherein the order (102) of comparison of the classifier entries with a frame is a function of a quality of service priority level, and the step (1124) of classifying a frame for which a match is found as a function of a parameter associated with the matching classifier entry.

Description

technical field [0001] The present invention generally relates to communication and network technologies, and more particularly relates to a frame classification method and system capable of rapidly classifying data frames in a QoS-capable wireless local area network (WLAN). Background technique [0002] In order to support the quality of service (QoS) of a wireless network (such as a wireless local area network WLAN), a frame classification module is proposed, which is provided in a logical link control (LLC) sublayer of a wireless base station. For example, in an IEEE802.1le WLAN environment, the base station may be part of a basic service set (BBS). Frame classification looks for a suitable stream identifier (Stream ID) to mark the frame passing down to the LLC sublayer by checking the frame against a classifier in a classification lable. The flow ID is associated with a specific set of QoS parameter values ​​that are used by the frame scheduling module to schedule frame...
