How to find how many application-layer protocols can be found in a .pcap file?
Is it statistics -> protocol hierarchy and just all the ones listed? or is there filtering needed
Can you better define what "application-layer protocols" are? Above a certain layer in the stack?
Which stack model - TCP/IP or OSI?
To be honest, I know it includes FTP SMTP HTTP and so on. but my task isnt specific, its given me a file and the following steps are: The Wireshark is a complex packet analysis tool and requires exploration. The tasks for the Wireshark segment are: • How many unique IPv4 addresses are available in this file capture? • How many application-layer protocols can be found in the .pcap file? • What are the names of these protocols? • Draft a network diagram that can be inferred from the captured data, include discussion on your decision.
reading through i believe its TCP/IP
