### 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*= 12000 bits, and that the link transmission rate along the link to router on the right is

*R*= 1000 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?

### Solution

The transmission delay = L/R = 12000 bits / 1000000000 bps = 1.20E-5 seconds

The number of packets that can be transmitted in a second into the link = R / L = 1000000000 bps / 12000 bits = 83333 packets

That's incorrect

That's correct

The answer was: 1.20E-5

The answer was: 83333
