UDP Pinger
UDP Pinger "Ping is a computer network administration software utility used to test the reachability of a host orn an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. Ping operates by sending Internet Control Message Protocol (ICMP) Echo Request packets to the target host and waiting for an ICMP Echo Reply." ping command is shown in the figure 1 below The output of a In 1 Userslelnas>ping cnn.com inging cnn.com [151.101.64.73] with 32 bytes of data: eply from 151.101.64-73:bytes 32 time-12ms TTL-5 eply from 151.101.64.73: bytes-32 time-12ms TTL-59 eply from 151.101.64.73: bytes-32 time-13ms TTL-59 eply from 151.101.64.73: bytes-32 time-12ms TTL-59 ing statistics for 151.101.64.73 Packets: Sent . 4, Received . 4, Lost .

Instead of using ICMP it will use UDP and connect to a server that will send back the response to the ping client. The code below simulates a simple Internet ping server written in the Python. The functionality provided by these programs (the given server and the client that you will write) is similar to the functionality provided by standard ping programs available in modern operating systems. However, these programs use a simpler protocol, UDP, rather than the standard Internet Control Message 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.
