Another similar application to the UDP Ping would be the UDP Heartbeat. The Heartbeat can be used to check if an application is up and running on the client side and to report one-way packet loss. The client continuously sends a message acting as a heartbeat in the UDP packet to the server, which is monitoring the heartbeat (i. e., the UDP packets) of the client. Upon receiving the packets, the server calculates the time difference. If the heartbeat packets are missing for some specified time interval, the server can assume that the client application has stopped working. Required:
Implement the UDP Heartbeat (both client and server). You will need to modify the given udppingserver. py, and your udppingclient. py.
