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 of comparing data in a frame to data in a plurality of classifier entries, wherein the order of comparison of the classifier entries with a frame is a function of a quality of service priority level, and the step of classifying a frame for which a match is found as a function of a parameter associated with the matching classifier entry.

Method and system for frame classification

The invention is related with the problem of utilizing data compression in a network of distributed stations. Often header compression is used to improve the bandwidth usage in networks, in particular wireless networks. Header compression could be implemented in access points or routers, but both implementations have serious problems, e.g. due to limited CPU power, lack of scalability, or handover latency. To resolve the problems the invention proposes to use a dedicated data compression server in the network and a new protocol to transparently deploy data compression in the network.
