Source wants to transmit 4 packets to the destination. Each packet is 1 Mb long. How long will the 4 packets
take to reach at the destination? Capacity of each communication link is 10 Mbps (as shown in the figure).

Q4.
Solve the following problem:
10 Mbps
Consider the following figure.
N
users
2
-10 Mbps
Router
1 Gbps link
-E
Router
10 Mbps
Assume that we can support 35 users in the above communication system. Each user can stay active 20% of
time. When each user is active, they transmit in 200 Mbps rate. The total capacity of communication link that
can support users is 1Gbps. Calculate the probability of more than 5 users (i.e., 6 or more users) to stay
active at the same time?
(If you are overwhelmed with the calculation, please write a program in your favorite programming language, just
like to way I wrote the program in my lecture slide.)
