– Network site visitors and congestion
Specialized aspects:

Even though ICMP messages are transferred within just usual IP datagrams, ICMP messages are frequently processed for a Distinctive case, unique from the standard IP processing. In lots of situations, it is essential to examine the info contained while in the ICMP information and output the correct mistake concept to the applying which produced the original IP packet.
Several typically made use of network utilities are dependant on ICMP messages:
The best recognized example of applying ICMP could be the ping functionality, which uses ICMP to question distant hosts for response and overall server latency. The ping operate is carried out using the ICMP “Echo request” and “Echo reply” commands.
