(24p) 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 RTTES msec. The second and third DNS servers contacted have RTTs of 40 and 25 msec, respectively. The Web page associated with the link contains 6 very small objects on the same server. The RTT between the local host and the Web server containing the objects is RTTITP = 41 msecs. a. Neglecting transmission times, how much time DNS HTTP DNS (in msec) elapses from when the client clicks on the link until the base object and all 6 additional objects are received from web server at the client, RTTA assuming non-persistent HTTP and no parallel TCP connections? RIT: RTTHITP RTTO b. What would your answer be, if the client is configured to support a maximum of 5 parallel TCP connections, with non-persistent HTTP. local DNS cache client
