Question

Computer networks

Tell me how to send incoming traffic and determine what it is intended for?
I have two clients they communicate through the server.
client1 -> sends login and password to client2 - through the server
client2 -> answers that the login password is correct and sends the answer through the server to client1
, the key comes to client1.
and the functionalad can be about 10 positions. how can I show both clients and server where everything goes?
client1.send(admin,admin) -> (server) -> client2(accepted, check)
client2.send(status OK) -> (server) {session key} -> client1(accepted session key)
there can be many different commands .
