For the following diagram, suppose within the 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 two DNS servers are visited before your host receives the IP address from DNS$.$ The first DNS server visited isthe local DNS cache, with an RTT delay of RTTo $=1$ msecs. The second DNS server contacted has an RTT$1$ of $3$ msecs. Initially, let's suppose that the Web page associated withthe link contains exactly one object, consisting of a small amount of HTML text. Suppose the RTT between the local host and the Web server containing the object is RT $=3$ msecs.
