Programming Assignment $2$: UDP Pinger

In this assignment, you will learn how a UDP load balancer works. A UDP load balancer is a

type of load balancer that utilizes User Datagram Protocol $($UDP$),$ which operates at layer $4-$

the transport layer $$ in the open systems interconnection $($OSI$)$ model. UDP traffic

communicates at an intermediate level between an application program and the internet protocol

$($IP$).$ In this assignment, You will see in its most basic form how a UDP Load Balancer

distributes the requests it receives to simple local servers.

Firstly, you will examine simple Internet ping servers and a corresponding client written in

Python. You can find these codes in the assignment attachment. The structure you should use

in your assignment is as seen in Picture$\_1.$ In this structure, the UDP load balancer receives

requests from the client side and distributes the requests respectively among the $3$ servers you

see.

Picture$\_1$

Below you will find the exact code of the servers and clients you need to use in the assignment.

Please include these four classes unchanged in your project and start analyzing them.

Client Code:

import time

import sys

from socket import $*$

# Check command line arguments
