- Consider a 100 Mbps LAN, connected to an ISP with 10 Mbps access link. Assume that: - HTTP is dominant traffic, with request/response rates =10req/s. - sizes for HTTP request and response msg. are 1kb and 1Mb, respectively. - Internet delay (RTT) is 1sec. tq0 sec. for 0.8 and tq5sec. for >0.8.. LAN tpr is negligible. - Calculate the response time to a request, w/o caching and with caching when =0.9 - For fairness, in the latter case assume that the request not satisfied by the web cache - Hint. We need ttr and tq for requests and responses, both inside LAN and over the access link
