How much data (in number of characters) must be exchanged between A and B in order for the connection-oriented communication to yield a shorter session than the connectionless communication? Explain.
In this exercise we will use a simplified mathematical model to analyze the tradeoff between connection-oriented communication and connectionless communication. Explain your answer. On a certain network both forms of communication are provided: • Using connection-oriented communication, it takes 50 second to establish a connection, after which a packet of up to 10 characters can be sent in 1.0 seconds over the connection, in either direction. • Using connectionless communication, a packet of up to 10 characters can be sent in 1.2 second. (The sending of each packet takes slightly longer than in the connection-oriented case, since each packet must find its way to the receiver.) Suppose A and B exchanges messages on this network. A initiates the communication and sends to B a message of 100 characters, which are partitioned into 10 packets. In reply, B sends a message of 50 characters, which are partitioned into 5 packets. Assuming that there is no delay other than the time it takes for establishing a connection (in the connection-oriented case) and for packet transmission:
