No AI USE PLEASE. You are using a web browser to load a webpage. Let’s assume the size of the webpage is negligible. The
access link rate of the webserver is 1 Gigabits per second. 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 an RTT
of RTT1, . . . , RTTn. Let RTT0 denote the RTT between the local host and the webserver containing the
webpage. Now answer the following:
1) Ignore all types of delays at the client and the servers. How much time elapses from when the
client clicks on the link of the webpage until the client receives the content of the webpage?
2) Now suppose, the HTML file references 10 additional objects (15 MB each) on the same server.
Considering only the transmission delay at the webserver for each of these objects and ignoring
all other delays at the host and the servers,…
In a client-server file distribution paradigm, let’s assume the server has an upload rate of 25 Mbps. Each
client’s download rate is 3 Mbps. Now consider multiple scenarios where the number of clients is 50,
200, and 1000. For each of these scenarios, consider 2 possible upload rates of each client: 200 Kbps,
and 1Mbps. For these 6 combinations of the number of clients and the client-upload rate, what are the
minimum distribution times for a file of size 30 Gigabit? Now, if the same file needs to be distributed in
a P2P paradigm, what will be the 6 minimum distribution times?

First study the attached code for a simple internet ping server (UDP_Ping_Server.py). You will have to
implement a corresponding client in python. The functionality provided by these programs will be similar
to the functionality provided by standard ping programs available in modern operating systems.
However, these programs will use a simpler protocol, UDP, rather than the standard Internet Control
1Message Protocol (ICMP) to communicate with each other. The ping protocol allows a client machine
to send a packet of data to a remote machine, and have the remote machine return the data back to the
client unchanged (an action referred to as echoing). Among other uses, the ping protocol allows hosts to
determine round-trip times to other machines.
Do not modify the attached server code. In this server code, 30% of the client’s packets are simulated to
be lost. The server sits in an infinite loop listening for incoming UDP packets. When a packet comes in
and if a randomized integer is…
