Extracted text: Consider the network depicted in the below figure. Suppose that router R1 receives a packet Pktl from host PC1. The length of packet Pktl is L = 25 Mbit. Router R1 takes 0.4 msec to determine the output link of packet Pktl. Packet Pktl is to be forwarded through the output link to router R2. Packet Pktl waits 136 ms at the output link for transmission. The transmission link of the link between router Rl and router R2 is R = 5 Mbps. The distance between router R1 and router R2 is 400 Km and the propagation speed over the link is 2*108 m/s. R2 PC1 R1 R3 Find the queuing delay of packet Pktl at router R1. Find the propagation delay of packet Pktl over the link from router R1 to a. b. router R2.
