Answer:
12.1 seconds
Explanation:
Step 1:
Assuming the following data :
N: Size of packet = 30 Mb
T: Transmission rate = 10 Mbps
C: Speed of light in copper = 2 * 10^8 m/s
L: Length of link 5000 km
Step 2:
Calculation of the Transmission delay and the Propagation Delay
Transmission delay = =
= 3s
Propagation delay = =
= 0.025s
Step 3:
Calculation of the end-to -end delay
The end-to-end delay = 4*(Transmission Delay+Propagation Delay) = 4*(3+0.025) = 12.1 seconds
