Abstract
Disclosed herein are a system and method for efficiently routing high-priority frames through a wireless network based on markings of the frames by a data link layer, a network layer, or an application layer in a five-layer protocol stack. When a real-time application, such as a video or gaming application, is to be sent to one or more stations in the wireless network, the access point determines the strategy for routing the high-priority frames based on the markings received from the data link, network, or application layer. Strategies include discarding non-I frames when there is congestion in the wireless network, replicating I-frames to assure reliable delivery to the stations, scheduling I-frames with preference, and moving I-frames ahead in a buffer in the access point.
