Abstract:
Data received over a shared network interface is directly placed by the shared network interface in a designated memory area of a host. In providing this direct memory access, the incoming data packets are split, such that the headers are separated from the data. The headers are placed in a designated area of a memory buffer of the host. Additionally, the data is stored in contiguous locations within the buffer. This receive and store is performed without interruption to the host. Then, at a defined time, the host is interrupted to indicate the receipt and direct storage of the data.
