Question

1. Suppose within your web browser you click on a link to obtain a Web page. The Web page associated with the link is an HTML file of very small size, but containing references to eight other objects. Each of these eight objects is also of very small size. Five of the eight embedded objects are on the same server as the base object (Server 1) while the remaining three are on a different server (Server 2). The round-trip time between the local host and Server 1 is 150 msec, and between the local host and Server 2 is 300 msec. What is the total response time for the Web page including displaying all embedded objects for each of the following cases? You should assume the best possible scenarios of obtaining the objects in each case. Explain your answers and support them with timing diagrams. a) Non-persistent HTTP with the browser configured for 5 parallel connections. b) Persistent HTTP with no pipelining and no parallel TCP connections. c) Persistent HTTP with pipelining and no parallel TCP connections. d) Persistent HTTP with no pipelining and 3 parallel connections.
