A method, system and computer program product for facilitating network data packet management. In one embodiment, a controller is configured to receive data packets. Incoming data packets are stored in DMA mapped packet buffers. A time stamp is associated with the packet buffers. When the associated time stamp exceeds a defined threshold, the controller is configured to copy the packet buffers stored in DMA memory to non-DMA memory. Once copied, the DMA memory previously used to store the packet buffers is available to receive new data packets. The controller is configured to continue copying aged packet buffers to non-DMA memory until an unallocated amount DMA memory is reached.
