Abstract: This paper presents a design project of network behavior identification system based on PowerPC processor and embedded Linux. Data plane of the system is optimized to meet the needs of working under the high-speed network environment. NAPI network device driver and efficient buffer storage structure are designed. Data processing flow of Linux network protocol stack is shortened to promote the performance of Linux. Experimental result shows the throughput of the optimized system is improved compared with the original system.
