Suppose within your Web browser you click on a link to obtain a Web page.

The IP address for the associated URL is not cached in your local host, so a DNS lookup is necessary to obtain the IP address.

 Suppose that “n” DNS servers are visited before your host receives the IP; the successive visits incur different RTTs. Further suppose that the Web page associated with the link contains the main HTML and eight small objects.

Here assume that getting the 8 objects and the HTML incur the same RTT. Assuming zero transmission time to transfer the objects, how much time elapses from when the client clicks on the link until the client receives *all* elements of the page (8 objects + main HTML)?

Answer this question assuming (a) Non-persistent HTTP with no parallel TCP connections or pipelining (essentially HTTP/1.0) (b) Persistent HTTP without pipelining or parallelization, and (c) Persistent HTTP with the browser configured for 5 parallel connections but no pipelining.
