# Throughput of the network in the given scenario

Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has 3 links of rates:

• R1 = 512 Kbps
• R2 = 2 Mbps
• R3 = 1 Mbps

What is the throughput for the file transfer (in Kbytes per minute)?

According to me the whole link is equivalent to a 512kbps link and according to that the efficiency = 512*60/8 (KBytes/min).

Is the logic and answer correct, or am I missing something?

• Explain how you came up with your answer. Commented Jan 10, 2015 at 13:13
• i compared this with a typical pipeline structure where for large no. of instructions the lag depends on the slowest segment and hence here R1 will be the one. Commented Jan 10, 2015 at 13:52
• This sounds very much like a homework question (and a bad one at that as one must assume how packets are distributed across the various links) Commented Jan 11, 2015 at 4:07
