As the rapid growth of network bandwidth,the capability of packet capture has became the bottleneck of whole network security system.To increase the capability of packet capture and decrease the system overhead,a packet capture oriented INIC was proposed.Implemented on high performance embedded system,the INIC apply techniques such as zero-copy,adaptive semi-polling,adaptive polling watchdog to ensure the system efficiency.The result of performance evaluation exposes that the INIC remarkably increases the system’s packet capture performance,decreases the host CPU’s utilization.
