Find a formula, in terms of N, L and R, that characterizes the end-to-end
delay of sending the N packets to Alice (i.e., the time needed for the last
bit of the Nth packet to arrive at Alice since Bob starts transmitting the
first bit of the first packet). Consider only the transmission delay that
occurs in sending packets in your analysis. Show your work in detail.

Suppose that KJ sends 3596 back-to-back packets, with each packet composed of 14,000 bits, to TA over 5 links (shown below). Suppose that the transmission rate of each link is 70,000 bits/sec (bps). Consider the routers to be store-and-forward routers. In such a scenario, find the endto- end delay of sending all the packets to TA (i.e., the time needed for the last bit of the last packet to arrive at TA since KJ starts transmitting the first bit of the first packet).

Suppose you want to deliver the gift to your friend, Jashim as a birthday gift. You packed the gift in five different packets, give them serial no and send them to your friend’s address at a time. Jashim has a PA to collect all packets and store them by their serial. If Jashim’s PA can receive all the packets serially then deliver them to Jashim. If any packet is missing, Then the PA inform you to resend the packet again.I. Which protocol you want to use to avoid over cost if resend is required.II. Describe your used protocol with an appropriate diagram using the above description.

Consider a packet of length L that begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let d, s, and R denotes the length, propagation speed, and the transmission rate of link i, for i=1,2,3 . The packet switch delays each packet by d . Assuming no queuing delays, in terms of d, s , R, (i=1,2,3), and L, what is the total end-to-end delay for the packet? Suppose now the packet is 1,500 bytes, and the propagation speed on all three links are 3125km/sec, 10000 km/sec, and 3333km/sec respectively. The transmission rates of all three links are 2 Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5,000 km, the length of the second link is 4,000 km, and the length of the last link is 1,000 km. For these values, what is the end-to-end delay? In the above problem, suppose R1=R2=R3=R and dproc=0. Further, suppose the packet switch does not store-and-forward packets but…

Suppose Alice and Bob are going to communicate using AES in CBC mode. Unfortunately Alice's message length (in bytes) is not a multiple of 16. Suppose the last block of her message is just a single zero byte. How can she pad out the last block so that she can use CBC mode? Since this needs to be a reversible operation, how does Bob recognize the padding and remove it?
