  • Hardware calculation of encapsulated IP, TCP and UDP checksums by a switch fabric channel adapter
    Publication number: 20040218623
    Abstract: A network interface adapter includes a memory interface, for coupling to a memory containing a first data packet composed in accordance with a first communication protocol, and a network interface, for coupling to a packet communication network. Packet processing circuitry in the adapter reads the first data packet from the memory via the memory interface, computes a checksum of the first data packet, inserts the checksum in the first data packet in accordance with the first communication protocol, and encapsulates the first data packet in a payload of a second data packet in accordance with a second communication protocol applicable to the packet communication network, so as to transmit the second data packet over the network via the network interface. The circuitry likewise computes checksums of incoming encapsulated data packets from the network.
