RETRANSMISSION CONTROL SYSTEM AND RETRANSMISSION CONTROL METHOD

摘要

A retransmission control system has: a memory in which a transfer data is stored; and a network interface. The network interface has: a packet processing unit configured to generate a transfer packet including the transfer data; and a DMA controller configured to read out the transfer data from the memory. In response to a data transfer instruction that instructs first-time transfer or retransmission of the transfer data, the packet processing unit obtains a packet header of the transfer packet and generates the transfer packet by appending the obtained packet header to the transfer data read out by the DMA controller.
