基于动态内存池和WinpCap的高速数据捕获技术

摘要

针对现代网络系统通信高速化,信息多样化,处理实时化的要求,提出了一种基于动态内存池和WinpCap的高速数据捕获技术.该技术具有速度快,丢包率低,效率高,移植性强的特点.经过系统测试和数据分析,证明了在丢包率小于0.03％的条件下,该技术可捕获最高速度为300Mbps的数据,能有效地应用于高速网络环境.%In this paper, a high-speed data capture technology based on dynamic memory pool and WinpCap is proposed to cater the requirements of high-speed communications, diversified information and real-time processing in modern communication system. The proposed technology has features of high speed, low packet loss rate, high efficiency and good portability. The system test and data analysis proved that the proposed technology can effectively capture the data at speed of 300 Mbps, and can work stably in high-speed network environment.
