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 localhost, 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 an RTT of RTT1, . . ., RTTn. Further suppose that the Web page associated with the link contains exactly one object, consisting of a small amount of HTML text. Let RTT0 denote the RTT between the local host and the server containing the object. Assuming zero transmission time of the object, how much time elapses from when the client clicks on the link until the client receives the object? Justify your answer.

Assume you use your Web browser to access a Web page by clicking on a link. Because the IP address for the related URL is not cached on your local host, a DNS search is required to acquire it. Assume that n DNS servers are contacted before your host obtains the IP address from DNS; each subsequent visit incurs an RTT of RTT1,..., RTTn. Assume that the Web page connected with the link has only one item, which is a little bit of HTML text. Let RTT0 represent the RTT between the local host and the server that has the item. Assuming that the item has a zero transmission time, how much time elapses between when the client clicks on the link and when the client receives the object?
Suppose a user has a webserver running at a machine with the name www.nadir.edu.net.pk and IP address 10.10.10.10. The authoritative dns address for this web server is with the name dns.nadir.edu.net.pk and with IP address 11.11.11.11. a. Write all the steps involved in inserting this webserver name in the DNS hierarchy. b. Write all the steps involved in retrieving the IP address of www.nadir.edu.net.pk
Suppose an HTTP client makes a request to the gaia.cs.umass.edu web server. The client has never before requested a given base object, nor has it communicated recently with the gaia.cs.umass.edu server. You can assume, however, that the client host knows the IP address of gaia.cs.umass.edu. How many round trip times (RTTs) are needed from when the client first makes the request to when the base page is completely downloaded, assuming the time needed by the server to transmit the base file into the server's link is equal to 1/2 RTT and that the time needed to transmit the HTTP GET into the client's link is zero? (You should take into account any TCP setup time required before the HTTP GET is actually sent by the client, the time needed for the server to transmit the requested object, and any propagation delays not accounted for in these amounts of time.) Choices A.0.5 RTT B.3.5 RTT C.1.5 RTT D.2.5 RTT E.0 RTT
Suppose that the RTT delay between a client and an HTTP server is 30 msecs; the time a server needs totransmit an object into its outgoing link is 0.85 msecs; and any other HTTP message not containing an objecthas a negligible (zero) transmission time. Suppose the client again makes 100 requests, one after the other,waiting for a reply to a request before sending the next request.Assume the client is using HTTP 1.1 and the IF-MODIFIED-SINCE header line. Assume 50% of the objectsrequested have NOT changed since the client downloaded them (before these 90 downloads are performed)How much time elapses (in milliseconds) between the client transmitting the first request, and the completionof the last request?
Suppose a user has a webserver running at a machine with the name nadir.edu.net.pk and IP address 10.10.10.10. The authoritative DNS address for this web server is with the name dns.nadir.edu.net.pk and with IP address 11.11.11.11. Write all the steps involved in retrieving the IP address of nadir.edu.net.pk
If a DNS lookup happens every 10 minutes and an HTTP file references 8 objects each time, how long would Non-persistent HTTP with no concurrent TCP connections last?
If DNS looks up occur every 10 minutes and the HTTP file references 8 items each time, how long would Non-persistent HTTP and no concurrent TCP connections last?
In order to implement a DNS amplification attack, the attacker must trigger the creation of a sufficiently large volume of DNS response packets from the intermediary to exceed the capacity of the link to the target organization. Consider an attack where the DNS response packets are 500 bytes in size (ignoring framing overhead). a. How many of these packets per second must the attacker trigger to flood a target organization using a 30-Mbps link? A 100-Mbps link? Or a 1-Gbps link? b. If the DNS request packet to the intermediary is 60 bytes in size, how much bandwidth does the attacker consume to send the necessary rate of DNS request packets for each of these three cases?

Suppose three hosts inside a private network with adress 172.18.3.1 , 172.18.3.2 and 4M172.18.3.3 need to access the HTTP server on external host 25.8.3.2 . Draw a Fivecolumn Translation table and explain its working.
How much time does Non-persistent HTTP and no concurrent TCP connections expire if DNS searching up occurs once per 10 minutes, and each time the HTTP file mentions 8 objects?
