Abstract
A method and apparatus are provided for processing data transmissions across data communications networks including ATM networks, for example, to support arbitrary user action on transmit completes. Sequential transport stream packets are obtained. A predetermined field of each transport stream packet is interrogated to identify a DMA on transmit complete. The transmission of a last cell in each transport stream packet is identified. Then responsive to identifying the DMA on transmit complete, an address for a DMA descriptor is fetched from the transport stream packet. The DMA descriptor is enqueued to a DMA engine to execute the DMA descriptor.
