A packet is sent from router A to router B over a link with a distance 1500km (propagation speed 2.5108m/s ). When the packet arrives at router A, one other packet is halfway done being transmitted on this outbound link and three other packets are waiting to be transmitted. Suppose all packets are 1,500 bytes and the link rate is 5Mbps. Each packet is processed when it arrives at a router, and the packet processing delay is 0.2ms. Please calculate the following delays in ms (millisecond), and fill in the blank spaces below: (please fill in numbers only in the space. For example, if the answer was 1.2ms, please fill in 1.2 in the space provided) A. Queueing delay at router A=ms B. Transmission delay at the link =ms C. Propagation delay at the link =ms D. The nodal delay from the time the packet enters router A until the packet arrives at router B (not processed yet )=ms E. Given that the packet arrival rate is 150 packet/s, calculate the traffic intensity for this link. Answer: \% (fill in integer percentage value, e.g. fill in 35 for 35% )
