Answer: For this type of application, it should be more appropriate a circuit-switched network.
Explanation: As the data are transmitted at a steady rate (x bits per second, for instance), and it's not transmitted in bursts, but during a relatively long period of time, it makes more sense to use a circuit-switched network instead of a packet-switched network, more useful when data shows in bursts (short intervals of data, followed by idle time, that can be filled with other data).
