In the class, we have learned a formula for the end-to-end delay of sending one packet of length L over 2 links of transmission rate R, (i.e., 2L/R). Give a formula for the total end-to-end delay of sending P packets of length L over N links of transmission rate R.
For one packet it is (NL)/R Ignoring queuing and processing delays
For P packets we will have
At t = NL/R, the first packet reaches the destination
At t = NL/R + L/R, the second packet reaches the destination because of the transmission delay of the first packet to the second link
Similarly…
At t = NL/R + (P-1)L/R , the last packet reaches the destination
Total end to end delay = (N+P-1)L/R
Do give a thumbs up and in case there are doubts leave a comment.

3. Suppose there is exactly one packet switch (or router) between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 = 1Mbps and R2 = 2Mbps, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length 18000bits? Assume that the propagation speed is 2 * 108 meters/sec, the distance between source...
1. Consider a packet of length L which 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 di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i=1,2,3. The packet switch delays each packet by dproc. Assuming no queuing delays, in terms of di, si, and Ri, (i=1,2,3), and L, what is the total end-to-end delay for...
Transmission Delay
Consider sending N packets each of length L bits from Host A to
Host B, as shown in the figure below. Assume that the links between
Host A and the Router and between the Router and Host B each has a
transmission rate of R bits per second. Assume all buffers are of
infinite capacity. Ignore all processing and propagation
delays.

from A to B as a function...
10. Suppose there is exactly one packet switch between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 and R2, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to- end delay to send a packet of length L? (Ignore queuing, propagation delay, and processing delay.) 11.

Consider sending a file of size 1 Gigabits from a server to a client. The server segments the files into packets of the size 10 megabits. There are 5 routers (6 links) between the client and the server. Assume there is no queuing delay and end-to-end propagation delay is 10 seconds. Compute the total delay for sending this file from server to client. Assuming we are sending the packets back to back and all links have the transmission rate 100...
Suppose N packets are sent, and each packet arrives at rate of L/2R to a link. Suppose the first packet arrives to a link at which no packets are being currently transmitted or queued. Each packet is of length L and the link has a transmission rate R. What is the average queuing delay for the N packets?
3. Consider sending real-time data from Host A to Host B over a packet-switched network. Host A takes a 32-bit measurement every millisecond, and Host A collects these into 128-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps, its propagation delay is 2 × 108 meters/sec, and its length is 1500 km. As soon as Host A gathers a packet, it sends the packet to Host B. How much time elapses from...
Note: b denotes bits and B denotes Bytes (1 Byte = 8 bits). Consider a packet of length L, which begins at source and travels over seven links to a destination. These links are connected through six routers. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1 to 7. The processing delay at each router is d-proc. The queuing delay at each router is d-que. What is the...
