Suppose within your Web browser you click on a link to obtain a Web page. The IPaddress for the associated URL is not cached in your local host, so a DNS lookup isnecessary to obtain the IP address. Suppose that n DNS servers are visited before yourhost receives the IP address from DNS; the successive visits incur an RTT of RTT1 , . . ., RTT n . Further suppose that the Web page associated with the link containsexactly one object, consisting of a small amount of HTML text. Let RTT 0 denote theRTT between the local host and the server containing the object. Assuming zero transmission time of the object, how much time elapses from when the client clicks on the link until the client receives the object?
