  • Patent number: 8671152
    Abstract: A multiprocessor system is provided for emulating remote direct memory access (RDMA) functions. The first sub-processing unit (SPU) generates a message to be transmitted. The second SPU is a processor for emulating the RDMA functions. Upon receiving a notification from the first SPU, the second SPU synthesizes the message into a packet according to a RDMA protocol. The third SPU is a processor for performing a TCP/IP protocol processing. Upon receiving a notification from the second SPU, the third SPU synthesizes the packet generated according to the RDMA protocol into a TCP/IP packet and then sends it out from a network interface card.

  • Patent number: 8175116
    Abstract: A network processing apparatus is provided. A send buffer receives from a protocol stack a long packet with a data length exceeding a maximum transmission unit defined for a network and stores the long packet. A payload dividing unit divides the payload of the long packet into a plurality of divided payloads. A header duplicating unit duplicates the header of the long packet so as to generate a duplicated header for the respective divided payload. A short packet generating unit attaches the duplicated header to the respective divided payload so as to generate a short packet with a data length equal to or less than the maximum transmission unit to be sent to the network. A sending unit sends the short packet to the network via a physical interface.
