A set of web browsers on the institutional network at USC generates an average of 15.0 requests/second for web objects of size 1.0 Mb. The access link to the public Internet is 15 Mbps. USC’s LAN operates at 1 Gbps. Assume LAN delay and internet delay are negligible. Suppose you installed a web cache and found that access link utilization was reduced to 7.5 Mbps. From your findings, what is the cache hit rate that resulted in this reduction in access link utilization?
