摘要:

网络扫描是网络测试工作中一个非常重要的环节,为提高网络扫描速率和增强扫描功能,对双端口网络扫描系统进行了研究；该系统拟采用双端口线速数据流发送与接收相分离的方式,同时结合发送数据流字段变化、接收地址学习、接收规则过滤等技术,使其形成多种高速网络扫描功能；应用分析表明,扫描速率最高可达156万次/秒,且功能具备实用、灵活和多样化等特点。

Abstract:

Network Scanning is a vital part in Network testing. In order to improve the network scanning rate and enhance the network scanning function, the dual-port network scanning system is studied. The system realizes the separation between dual-port line speed data stream transmitting and receiving. At the same time, combining send data flow field change, receiving address learning, receive rules filtering and other technology, making the system develop a variety of high-speed network scanning feature. The application shows that the scanning rate up to 1560000 times per second, and possess the function of practical, flexible and diverse.
