A set of priority parameters for network traffic on the data communication network is stored. Based on a specific application determination, based at least in part on a source IP address, a source port address, a destination IP address, a destination port address and a protocol, an airtime fairness ratio (ATR) for the session with a specific station from the set of priority parameters concerning application priority is assigned. A higher ATR results in more packets being stored in the queue for processing and a lower ATR results in fewer packets being stored in the queue for processing, thereby affecting airtime.
