IEEE 802.16 provides quality of service by providing five different service classes. When a packet reaches the MAC layer, the packet classifier has to classify the packet such that the packet is associated with appropriate QoS. In this paper, a packet classification algorithm is proposed that exploits the HTTP header of the application layer to determine the type of data and classify the data. The extension and MIME type (content type) headers are used to classify the packets. Further the algorithm is enhanced by considering the type of user as an additional parameter during packet classification. Simulations are done on variable bit rate video data.
