(Nowadays, in the process of front-line management of faults, sniffer software is often used to analyze data packets in the network, so as to provide more convincing data for fault management and related parts (such as development). It should be said that the sniffer's package text has indeed played a great role in management issues, but many times the sniffer data package provided by some people captures all data, which is very confusing. It takes a lot of effort to understand the data. In many cases, the corresponding network topology map of the captured packets, the source port, destination port, IP address, etc. in the data packet are not given, which is not conducive to the analysis and positioning of the relevant personnel. To this end, I will make a case in this area for your reference. I hope you can provide more valuable data to relevant personnel.)
