I need a person with an absolute idea about networking protocol

My task is to take any network protocol and switch it's fields in the header and observe the difference in wireshark....but the output should be the same on the terminal....only the fields sequence should be modified or u can drop the redundant bits we can use any protocols like SMTP, MQTT i want 2 protocols to be done....and I want to observe the modified difference on wireshark [login to view URL] bits within certain fields, sequence [login to view URL] bits [login to view URL] bits [login to view URL] or redundant 5. remove redundant bits 6. packet compression [login to view URL] and relation with fields in the packet
