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 T0 =15 msecs. The second and third DNS servers contacted have T1 =18 msecs and T2 =23 msecs, respectively. Suppose the RTT between the local host and the Web server containing the object is T3 =14 msecs. Suppose the HTML object references 5 very small objects on the same server. Neglecting transmission times, how much time (in msec) elapses from when the client clicks on the link until the base object and all 5 additional objects are received from web server at the client, assume that the client is configured to support a maximum of 5 parallel TCP connections, with persistent HTTP? Answer: The total time = msec
