# We will need the following module to generate randomized lost packets
import random
from socket import *
# Create a UDP socket
# Notice the use of SOCK_DGRAM for UDP packets
serverSocket = socket (AF_INET, SOCK_DGRAM)
# Assign IP address and port number to socket
serverSocket.bind(('', 12000))
while True:
# Generate random number in the range of 0 to 10
rand = random.randint(0, 10)
# Receive the client packet along with the address it is coming from
message, address = serverSocket.recvfrom (1024)
# Capitalize the message from the client
message = message.upper()
# If rand is less is than 4, we consider the packet lost and do not respond
if rand < 4:
continue
# Otherwise, the server responds
serverSocket.sendto (message, address)

Information Systems" 9th Edition:
Chapter 7: Discussion questions: 4. How could you use a
community of practice (COP) to help you in your work or
studies? How would you go about identifying who to invite to
join the CoP?
Chapter 8: Discussion questions: 2. Thoroughly discuss the
pros and cons of buying versus building software.
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 RTTo 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, recalculate the…

- 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?
