Problem
Let us assume a client and a server with one millisecond as time required for a message to travel from the client to the server (or from the server to the client).
I. Draw a sequence diagram that shows the messages exchanged for establishing a TCP connection secured by TLS 1.3, assuming that the client has never connected to the server in the past. How much time will it take to establish the connection?
II. Draw a sequence diagram that shows the messages exchanged for establishing a QUIC connection secured by TLS 1.3, assuming that the client has never connected to the server in the past. How much time will it take to establish the connection?
III. Why does the connection establishment take a longer time in one of the two cases?
