(Internet Control Message Protocol) is an Internet protocol that is focused on the control of messages and the reporting of errors. In design, ICMP is configured to provide these functions as a mediator between a gateway and a host server. The presence of ICMP helps to protect the integrity of the messages that are relayed back and forth between the two devices, as well as make efficient use of the Internet Protocol datagrams that are present.
Being one of the core protocols within the overall protocol suite, ICMP takes on the direct responsibility of processing error messages. This can be especially helpful in a networked environment, as ICMP makes it possible for a server to send out an error message to all connected workstations in the event that a program is taken offline or is temporary unavailable for some reason. This makes ICMP a valuable tool in making the most use of the operating system interface on the network, without tying up a lot of resources at the same time.
How Does ICMP Work?
The beauty of being the go-between for the host server and various connected devices is that ICMP can encapsulate the message in a way that protects the content,...
