How long does it take to send a 19 MiB file from Host A to Host B over a circuit-switched network, assuming:

58.4 ms

Explanation:

How long does it take to send a 14 MiB file from Host A to Host B over a circuit-switched network, assuming:

Total link transmission rate = 31.1 Gbps.

Network is TDM, with 11 permitted users, each with an equal time slot size.

A link connection requires a setup time of 51.7 ms.

Solution:

For TDM transmission, the bandwidth is divided equally between the users for transmission.

Transmission rate of each user = 31.1 Gbps / 11 users = 2.83 Gbps = 2830 Mbps

Time taken for file transmission = file size / transmission rate = 19 Mb / 2830 Mbps  = 0.0067 seconds = 6.7 ms

Total time taken = Set up time + transmission time  = 51.7 ms + 6.7 ms = 58.4 ms

The total transmission time is 58.4 ms
