7. Consider the given scenario where Host A wants to send a file to host B. Propagation speed at each link is approximately 3x10 m/sec, and processing and queuing delays at each router are 20 msec and 25 msec, respectively. Calculate the end to end delay between Host A and Host B, and the thruput achieved, when: a. File size is 1500 bytes and only one packet is sent. b. File size is 6000 bytes and four packets are sent (1500 bytes in each packet). Host A L1 = 6 km R1=500 kbps R1 I L2 = 600 km R2= 2 Mbps R2 L3 = 6 km R3=3000 kbps Host B
