Abstract: A network interface device includes receive logic, which is coupled to receive from a network a sequence of data packets, each packet including respective header data. A protocol processor is coupled to read and process the header data so as to identify a group of the received packets that contain respective fragments of a data frame, the fragments having a fragment order within the data frame. Host interface logic is coupled to a host memory accessible by a host processor, and is controlled by the protocol processor so as to allocate space for the data frame in the host memory, and to reassemble the fragments of the data frame in the fragment order in the space allocated in the host memory.

Abstract: A network interface device includes host interface logic, arranged to receive from a host processor a frame of outgoing data that includes outgoing header information and outgoing payload data, and to separate the header information from the payload data. A transmit protocol processor is coupled to read and process the outgoing header information from the outgoing header memory so as to generate at least one outgoing packet header in accordance with a predetermined network protocol. Transmit logic is coupled to receive and associate the at least one outgoing packet header with the outgoing payload data from the outgoing data memory, so as to generate at least one outgoing data packet for transmission over a network in accordance with the protocol.
