RTT 2 Web Server RTT 1 RTTHTTP RTTo Local DNS cache Client B) 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 three DNS servers are visited before your host receives the IP address from DNS: . The first DNS server visited is the local DNS cache, with an RTT delay of RTTo = 1 msecs . The second and third DNS servers contacted have an RTTs of 6 and 10 msecs, respectively. Initially, let's suppose that the Web page associated with the link contains exactly one object, consisting of a small amount of HTML text. Suppose the RTT between the local host and the Web server contains the objects RTTHTTP=83 msecs (1) Assuming zero transmission time for the HTML object, how much time elapses from when the client clicks on the link until the client receives the object
