摘　　要：介绍了基于Windows下一种多网卡转发技术。这种技术能够用在万兆级别的网络监控系统中。在NDIS中间层中,能够完成网络数据包的捕获和处理,并且数据包能够被指定网卡转发。为了保持网络监控系统的有效性,相同的源IP数据包一般要被相同的网卡转发到下层服务器进行处理,提出了一种快速查找IP的算法来解决这个问题。最后,验证性实验结果证明提出观点的可行性和正确性。This paper introduces a Multi-NIC forwarding technology in Windows embedded system.The technology can be used in network monitoring of 10-Gigabit level of traffic.On the base of the research on using NDIS IMD to realize packet capturing and packet analysis,packets can be forwarded by the specified NIC.In order to maintain the effectiveness of network monitoring,the packets of the same source IP are generally forwarded by the same NIC,so an algorithm quickly finding IP in IP address library is introduced.At last,the results of verification tests show that the views put forward in this paper are feasible and correct.
