# Host A sends a packet to host B over a link with a distance $1500 \mathrm{~km}$ (propagation speed $2.5 \times 10^{8}$ $\mathrm{m} / \mathrm{s})$. When the packet arrives, 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 $5 \mathrm{Mbps}$. Each packet is processed before entering the link (and link buffer), and the packet processing delay is $0.2 \mathrm{~ms}$. 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 $1.2 \mathrm{~ms}$, please fill in 1.2 in the space provided) A. Queueing delay = $\mathrm{ms}$ B. Transmission delay $=$ ms C. Propagation delay $=$ $\mathrm{ms}$ D. The end to end delay = $\mathrm{ms}$ 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 $35 \%$ )
