description A method of handling retransmission and memory consumption tracking of data packets includes storing data packets from different data channels in respective transmitter ring buffers allocated to the data channels when the data packets are not marked for retransmission, and facilitating retransmission of data packets from a specified ring buffer corresponding to a retransmission sequence number. The method also may include storing received data packets out of sequence in respective receiver ring buffers, marking a descriptor indicating a tail location of the stored data packets, and reclaiming memory space in the ring buffer based on the marked descriptor. The method may include storing a payload address associated with received data packets, marking a descriptor associated with the payload address to indicate the stored data packets have been consumed for processing, and reclaiming memory space when a register contains an indication of the stored payload address based on the marked descriptor.
