a)
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.
Amount of elapsed time:
While clicking on a link to open a web page, the IP address of the associated web page is not cached in the local host and hence a DNS lookup is used to identify the local host.
As the webpage is not cached and therefore must be found before the file can be requested and then received by the contacting host.
It is given that visits to “n” DNS servers to find the site occur a round-trip time (RTT) which adds up to “RTT1, RTT2,… RTTn” ,in which the numbers of RTT represents the DNS number.
- Therefore the total time it takes for the host to obtain the IP address can be denoted as: “RTT1+RTT2+RTT3+…RTTn”.
Given Data:
The HTML file references eight very small objects on the same server.
To Find:
Non Persistent HTTP with no parallel TCP connections:
