Given three packets of size 1500 bytes each are ready inside Computer 1 to be transmitted onto Link 1. Computer 1 has zero processing delay. Assume each router has zero queuing and zero processing delay. Link 1 is a 10 Mbit/sec link and 5000 km long. Link 2 is 100 Mbits/sec and is 5000 km long. Link 3 is 1000 Mbits/sec and is 5000 km long. Propagation speed is 2 × 10 8 m/s. Assume a router has to receive all of a packet before it can start sending it out along the next link (assume store and forward).
a) What is the total end to end delay for packet number one (time from first bit output on link 1 until last bit received at Computer 2)?
b)How much time goes by between when the last part of packet one is received by router 2 and when the first part of packet two arrives at router 2? (How far apart are the packets in time on link 2?)
c)How much time goes by between when the last part of packet one is received by Computer 2 and when the first part of packet number two arrives at Computer 2? (How far apart are the packets in time on link 3?)
Edit: Regarding the comment, there are 3 total packets each of size 1500 bytes..all of the questions are discussing one or two of the specific packets
Question a)
Here I first calculated the transmission time and propogation time of all links.
Below here i calculated the timeilne of packet1 and packet2 and we will use this for solving question b) and c).
Question b) and c)
Here i used the above calculation to solve these questions.

Questions: 1. (15pt.) Suppose that a file of 10 bytes is transferred between two hosts, and packet size is 10 bytes. Assume packets are sent back-to-back with no overhead of encapsulation. Calculate the file transmission latency (from first bit sent to last bit received) for (a) Single store-and-forward 1-Gbps switch is in the path, each link introduces a propagation delay of lus, and either queucing or processing delay can be omitted (b) Same as (a) but with three switches; (e)...
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...
Suppose that Router A and Router B are connected via a 10 Kbps link, and that the two routers are 20 meters apart. Suppose that Router A is transmitting a packet, and that there are 7 additional packets in the queue of the router, when a new packet arrives at Router A. Suppose that 500 bits of the currently-being-transmitted packet has been transmitted by Router A. Also, assume the following a. Every packet consists of 1000 bits. b. Propagation speed...

(a) A data link with a 1 Gigabits/sec capacity is used to transmit packets made up of 1400 bytes of data and 100 bytes of protocol control information. Each packet is acknowledged by a short frame of size 150 bytes. The propagation speed in the transmission medium is 200,000 km/sec. Consider the buffering and processing time in the nodes to be negligible. A node A communicates with a node B, with a distance between nodes A and B of 16...
