3. Suppose a 1 Gbps link has exponential packet interarrival time and service time. We like to apply the queuing theory and Little’s result to calculate mean latency and occupancy.a. If the mean arrival rate is 500 Mbps, what are the mean latency, queuing time, and occupancy?b. If the link bandwidth and mean arrival rate are increased by an order of magnitude to 10 Gbps and 5 Gbps, respectively, what are the mean latency, queuing time, and occupancy?3．假设有一条1Gbps的链路，具有指数级的数据包到达间隔时间和服务时间。我们想运用排队论和Little结论来计算平均等待时间和平均占用时间。a.如果平均到达速率是500 Mbps，则平均延迟，排队时间，占用时间各是多少？b.如果链路带宽和平均到达速率分别增加幅度为10Gbps和5Gbps，则平均延迟，排队时间，和占用时间分别是多少？
