. Web caches. [15 points Suppose on a certain network there are 600 web requests per second. Each request has an average size 1Kb. Suppose the link to the Internet is a 1.5 Mbps link. a. What is the utilization/traffic intensity of this link? uppose the network administrator was worried about queuing delays at the router and wanted to ring the utilization down to 30%. If she decided to upgradethe link, what size link would they have to upgrade to? b. S c. If she decided to use a web cache instead, what would be the required hit rate to achieve the desired result
