Design and Research of Data Packets Transmission by Shared Memory Block Based on NDIS

In the case of network applications become more common and computer network security issues become more prominent, intercepting and analyzing network packets is important. However, network environment traffic is large. How to intercept and analyze network packet effectively is a crucial issue. This paper research the process of NDIS intermediate driver capture packets in the Windows platform and propose a mode of shared memory blocks that transport data packets to the application layer software to analyze. This way can improve the efficiency of communication between kernel layer and application layer and reduce the probability of losses during the packets transmission.
