摘　　要：文章提出了一种Windows下高效网络协议分析软件的实现方法,从改造开源网络协议分析软件wireshark入手,将捕获的数据包写入共享内存,然后基于MFC编程从共享内存将数据包取出并进行重组、过滤和分析处理,实现了软交换系统中各设备实体间SIP协议数据的实时动态图形显示,最后对软件进行了验证测试。对于软交换系统中SIP信令分析具有实际应用价值,对于类似网络协议分析软件的开发具有一定的借鉴意义。An efficient network protocol analysis software under Windows was designed and implemented by modifying wireshark to write the captured packets into shared memory.Based on MFC the data were read out,and after reassembling,filtering and analysis of the captured packets, the signaling flow between the entities of Softswitch system was displayed,and the performance of the software was tested and validated by experiments.The software is helpful to the analysis of SIP signaling in Softswitch system,and also can be used for reference to similar protocol analysis software design.
