Abstract
A method for dropping lower priority packets for transmission over a wireless communication medium is provided. A central device receives one or more packets to be transferred to one or more data providers, each packet having a priority. Then, based on the priority, a media access controller stores each of the packets in one or more priority queues in a fixed shared memory space in such a way as to maintain the order in which the packets were received in each of the priority queues. The media access controller monitors the number of packets in each of the priority queues and signals an interrupt when a packet threshold is exceeded in one or more of the priority queues. The media access controller then drops lower priority packets in the fixed shared memory space based on the order received to guarantee that there is enough memory to store higher priority packets in the fixed shared memory space.
