Consider a network where two store-and-forward packet switches are between System A and System B. Suppose System A sends a 1,024 byte packet to system B. Also suppose the following:Each packet switch takes 4 msec to process a packetA. The propagation speed on all links is 2.5 x 108 m/secB. The transmission speed for all links is 10 MbpsC. The length of the link between A and S1 is 5,000 kmD. The length of the link between S1 and S2 is 10,000 kmE. The length of the link between S2 and B is 3,000 kmF. There are no queuing delays in the packet switches1. What is the delay between System A and the first packet switch? (i. e., what is the time between the first bit of the packet leaving System A and the last bit of the packet arriving at the packet switch?)2. What is the end-to-end delay for the packet (i. e., how long does it take between the first bit of the packet to leave System A and the last bit of the packet to arrive at System B?)
