X86 board card-based No.7 signaling analysis method and analysis platform

The invention discloses a No.7 signaling analysis method and analysis platform based on an x86 board card. According to the method, quick support for various fields of No.7 signaling analysis is realized, and support for different ITUs (International Telecommunication Unit) used for protocols such as ISUP (International Subscriber Identity Protocol) and MTN (Multimedia Transfer Network) is realized by modifying a wireshark source code in combination with the wireshark source code and the type of data encapsulation; according to the method, details of Wreshark source codes for parsing the No.7 signaling are studied, definition understanding of each protocol layer field of the No.7 signaling is combined, a new function is added to support correct data parsing, and meanwhile, the method can also rapidly support parsing of new fields. According to the method, the support of different data encapsulation types is realized by analyzing the data encapsulation, and the corresponding fields are effectively positioned b
