Program Plan Intro

DNS:

DNS stands for Domain Name System. It is the way that internet domain names are located and translated into internet protocol address.

TCP:

TCP stands for Transmission Control Protocol which is a standard that establishes and maintain a network conversion with the use of application programs.

Round Trip Time (RTT):

The length of time it takes for a signal to be sent along with the length of time to be acknowledged is called the round trip time.

There are “n” DNS servers in the connection.

Download delays for 100 objects (HTTP 1.1 with browser caching). Consider an HTTP 1.1 client and server. The RTT delay between the client and server is 2 seconds. Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds, as shown below for the first of these 100 requests. initiate TCP connection RTT request file RTT file received time You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 100 requests, one after the other, waiting for a reply to a request before sending the next request. 352 secs Using HTTP 1.1, how much time elapses between the client transmitting the first request, and the receipt of the last requested object, assuming the client uses the IF- MODIFIED-SINCE header line, and 50% of the objects requested have not changed since the client downloaded them (before these 100 downloads are performed)? 350 secs 252 secs time to…
1. It is a protocol for encapsulating data packets that use one routing protocol inside the packets of another protocol. 2. It is a hash function that has been deprecated for uses other than as a non-cryptographic checksum to verify data integrity and detect unintentional data corruption. 3. An algorithm which is a pseudorandom function family in that it can easily generate arbitrary portions of the keystream without having to start from the beginning. 4. What is the most popular and widely implemented flavor of STP? 5. An algorithm that comprises of a series of linked operations, some of which involve replacing inputs by specific outputs (substitutions) and others involve shuffling bits around (permutations). 6. It is calculated using port cost values associated with port speeds for each switch port along a given path in STP 7. A proprietary architecture that authenticates users and devices using the identity-enabled network approach, and enables the government workforce to connect…
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 RTT = 4 msecs. The second and third DNS servers contacted have RTTs of 45 and 24 msecs, respectively. Initially, let's suppose that the Web page associated with the link contains exactly one 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 = 9 msecs. Assuming zero transmission time for the HTML object, how much time elapses from when the client clicks on the link until the client receives the object? (Do not forget the TCP handshake(s).) 82 msecs O 91 msecs O 46 msecs O 67 msecs
