How long does the session between A and B last, using 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:

1. The term walled garden refers to an array of apps available for purchase that do not require pre-approval. 2. Unless developing a specialized app that will cost more than $19.95, prototyping is most likely the best way to develop an app. 3. When developing an app, quick releases are important, and there is a strong advantage to being the first to introduce a certain type of app. 4.
