This article is built on the basis of the network protocol, to restore the original network data information, mainly for the network users to access the network, the transmission of image resources and data reduction. This article relates to the original network packet capture, packet parsing, TCP fragment reassembly, pictures restored four aspects. The whole system is based on VS platform combined with MFC and MySql database of network data reduction system. In the packet capture module uses Winpcap capture network packets to the maximum to avoid packet loss occurs. Through data parsing module for TCP protocol SEQ field and ACK ,and other important fields and categorize all of the data packets, and then use the SEQ and ACK value to complete the restructuring of the TCP data flow divided. Finally in collecting the data of all the restructuring good TCP data flow information, eventually achieve the reduction of image.
