Suppose you use your Web browser to access a web page. The IP address for the associated URL is not cached in your local host, so a DNS lookup is necessary. Suppose that n DNS servers are visited before your host receives the IP address from DNS; the successive visits incur an RTT of RTT1, . . . , RTTn. Further suppose that the Web page associated with the link references ten additional small objects on the same server. Let RTT0 denote the RTT between the local host and the server containing the web page. Assuming zero transmission time for all the objects. How much time elapses from when you click on the link until your browser receives all the objects with the following three situations? (1) Non-persistent HTTP with no parallel TCP connections? (2) Non-persistent HTTP with the browser configured for 4 parallel connections? (3) Persistent HTTP?
