A circuit-switched network would be more appropriate for this application.
<u>Explanation</u>:
The method of Circuit switching helps in the establishment of a network with the nodes that are in communication. The network will be established in the earlier stages before the two nodes starts to communicate with each other. The bandwidth that is essential fro the communication will be reserved and the communication will take place without any interruption.
The example that is given in the question requires a circuit switched network suiting its need. This is because long sessions are essential and there are some needs of bandwidth too. Circuit switched networks helps in this scenario reserving bandwidth for each session of the application and there wont be any wastage. There is also an advantage of ignoring he costs that are related with the setting and disconnecting the circuit connection even if an application has a session with longer time duration.
