Web Caching Consider tne following network, where hosts in an institutional network can download files fro both remote origin servers and a local proxy cache. origin Servers Dublie Internet 2 Mbps access link loc. web che Suppose: The average object size is 100,000 bits. The average request rate from the institution's browsers to the origin servers is 10 requests/sec. The missing rate of the web cache is 0.3 The round-trip delay from the access router to any origin server and back to router is 2 sec. The round-trip delay from the clients to the local proxy cache is 2 msec. - Ignoring the time for DNS query. For the average Internet access delay, use /(1-A), where is the average time required to send an object over the access link and is the arrival rate of objects to the access link Find the average total response time for a client to download a file
