A method, computer program product, and apparatus for managing data packets are presented. A data packet in the data packets is stored in a first portion of a memory in response to receiving the data packet at a device. The first portion of the memory is allocated to the device. A determination is made whether a size of the data packet is less than a threshold size. The data packet is copied from the first portion of the memory allocated to the device to a second portion of the memory in response to a determination that the size of the data packet stored in the memory is less than the threshold size.

Direct memory access memory management

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.
