随着网络速率的不断提升,网络安全系统对于数据包内容的实时检测变得越发困难,基于零拷贝思想和多核技术设计实现了一种高速报文内容检测系统,系统采用零拷贝的思想消除数据包在处理过程中的复制操作,提高系统对数据包的处理效率,并通过创建可并行处理的数据包缓冲区,实现对捕获数据包的并行处理,成倍提高系统对数据包的处理速率.经测试,本文实现的高速报文内容检测系统对高速数据流具有很好的处理性能.
With the continuous improvement of network speed, network security system becomes more and more difficult for real-time detection of data packet contents. Based on zero-copy idea and multi-core technology, a high-speed message content detection system is implemented. The system uses zero-copy idea to eliminate data Packet in the process of replication operations to improve the efficiency of the system to deal with the data packet, and through the creation of data packets can be parallel processing buffer, capture data packets to achieve parallel processing, doubling the system to improve data packet processing speed. After testing, this paper implements a high-speed packet content detection system for high-speed data flow with good processing performance.
