Consider the network provided in Fig. 2.12 of the textbook. For simplicity, let's assume that the LAN delay is 0 and the Internet delay is 2 seconds. Assume that the average object size is 80Kb and there are 20 requests per second from the institution's browsers to the origin servers. b. Find the total response time. The total response time/delay is the sum of LAN delay, access delay and Internet delay. Here, the average access delay can be calculated as x/(1-y) where y is the traffic intensity you calculated above and x is the average time required to send one object over the access link.
