Suppose Host A wants to send a large file to host B. The path from Host A to Host B has three links, of rates R1 = 500 kbps, R2=2 Mbps, and R3 = 1 Mbps. Assuming no other traffic in the network, what is the throughput for the file transfer? 500 kbps

The answer is 500 kbps

Explanation:

Consider the given data in the question.

R1 = 500 kbps

R2=2 Mbps

R3 = 1 Mbps

Now as it is mentioned that there is no other traffic in the network.

Thus,

throughput of the file = min {R1, R2, R3}

throughput of the file = min {500 kbps, 2 Mbps, 1 Mbps}

T/P of the file = 500 kbps
