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 four DNS servers are visited before your host obtains the

IP address. The first DNS server visited is the local DNS server, with an RTT delay of RTT$0$

$=5$ msecs. The second, third, and fourth DNS servers contacted have a roundtrip time of

RTT$1=32,$ RTT$2=11,$ and RTT$3=31$ msecs, respectively. Initially, assume that the Web page

associated with the link contains exactly $1$ object, consisting of a small amount of HTML

text. Suppose the RTT between the local host and the Web server containing the object is

RTTHTTP $=37$ msecs. In the following questions, we assume no transmission delay for HTML

requests$/$responses$.$
