Host A is sending a file to Host B. There are 3 links (therefore 2 switches) between the hosts. The file is segmented into packets of 40 bytes, with a 10 byte header added to each packet. Each link has a transmission rate of 100 kbps and a speed of 1000 km per sec. The switches are 100km away from each other. Host A is 50 km away from the first switch while Host B is 150 km away from the second switch. Data travels from Host A to the first switch, on to the second switch and then to Host B. What is the propagation delay (in seconds) when a packet of data travels between the 2 routers?
Answers
Answer:
The propagation delay is "0.1 Sec".
Explanation:
Please find attachment of the figure.
The given values are:
Transmission rate of each link
= 100 kbps
Distance
= 100 km
Speed
= 1000 km
Now,
The propagation delay between R1 as well as R2 will be:
⇒ [tex]\frac{DR_1 R_2}{speed}[/tex]
On substituting the estimated values, we get
⇒ [tex]\frac{100 \ km}{1000} \ Sec[/tex]
⇒ [tex]0.1 \ Sec[/tex]
