Origin servers Consider the scenario presented in the Figure 1, where public Internet is connected to institutional network through a 15Mbps access link. Consider the average object size is 550,000 bits and the institution's browsers make requests at a rate of 25 per second. Also, consider that the amount of time taken to receive a response after router (Ri) at Internet side makes the HTTP request is 2 seconds on average and delay incurred in sending and receiving objects to/from Ro in Institutional LAN is negligible. Public Internet RI > 15 Mbps access link Ro 100 Mbps LAN If we have a way to model the average access delay as w where a is the arrival rate of the objects to the access link, and A is the average time to send an object over the access link. Now answer the following: 1-a Institutional network a. What is the total average response time? b. Considering there is a Cache installed in Institutional Network that has hit rate of 0.6, what would be the total response time?
