Consider a webpage consisting of a base HTML file and 2 embeded GIF objects on the same web server. The IP address for the server is initially not known to the client. Suppose that one DNS server in each class of DNS hierarchy should be visited before the client receives the IP address. Suppose the time needed to contact any (web or DNS) server and receive a response is RTT . How much time elapses from when the client clicks...

Please Help! thanks in advance 1. 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 n DNS servers are visited before your host receives the IP address from DNS; the successive visits incur a RTT (round-trip time) of RTT1, … , and RTTn. Further suppose that the...

You download a small HTML file that references 8 small objects (that is, ignore transmission times). All these 8 objects reside on the same server. One RTT is 300 ms. How much time does it take to download all 9 objects using nonpersistent but concurrent (max 6) HTTP connections? Give answer in seconds to one decimal digit.

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 look up is necessary to obtain the given IP address. Further suppose that 3 DNS servers are visited before your host receives the IP address form DNS. The round trip time between the client and the ithDNS server is Ti(1≤i≤3), and that between the jthDNS server and the...

Please Answer all Questions on Networks, They all involve calculation ( 1-9 Questions) "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second...
