Computing the one-hop transmission delay

Consider the figure below, in which a single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link.


Suppose that the packet length is L= 16000 bits, and that the link transmission rate along the link to router on the right is R = 10 Mbps.

Round your answer to two decimals after leading zeros

Question List

1. What is the transmission delay?

2. What is the maximum number of packets per second that can be transmitted by this link?


The transmission delay = L/R = 16000 bits / 10000000 bps = 0.0016 seconds

The number of packets that can be transmitted in a second into the link = R / L = 10000000 bps / 16000 bits = 625 packets

That's incorrect

That's correct

The answer was: 0.0016

Question 1 of 2

The answer was: 625
