Network Processor System and Network Protocol Processing Method

摘要

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.
