NETWORK INTERFACE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a network interface device that stably transmits data packets to a network at high speed.

SOLUTION: In the network interface device 101, a transmission buffer memory 124 stores AV stream data packets transmitted for specific communication connection while a transmission FIFO 114 stores data packets to be transmitted other than the AV stream data. A packet branch circuit 121 separates ACK packets replied to the AV stream data packets from among the received packets. An ACK packet analysis circuit 122 extracts prescribed information from in the separated ACK packets. A transmission buffer control circuit 123 controls the transmission buffer memory 124 on the basis of the extracted information.
