ICMP is a necessary component to execute Internet Protocol. ICMP is a control procedure which implies that it does not lug any kind of application data, yet data regarding the condition of the network itself. ICMP is utilized to report:

– Errors in the core communications of the network applications
– Availability of remote hosts
– Network web traffic as well as congestion

Technical details:

Net control message protocol belongs to the Internet procedure collection as defined in RFC 792. ICMP messages are generated in feedback to errors in IP (as defined in RFC 1122) or for diagnostic or routing functions.

ICMP messages are produced at the IP layer. ICMP messages are transferred within regular IP datagrams, ICMP messages are usually processed as an unique instance, different from the usual IP handling. In numerous situations, it is necessary to examine the data consisted of in the ICMP message and outcome the appropriate error message to the application which produced the original IP package.
Lots of generally utilized network energies are based upon ICMP messages:

The very best known example of utilizing ICMP is the ping function, which utilizes ICMP to quiz remote hosts for feedback and overall server latency. The ping function is applied using the ICMP “Echo demand” and “Echo reply” commands.

ICMP likewise supports the traceroute command, which is made use of to recognize intermediate “dives” between a given client as well as web server. The trace course command is executed by transmitting UDP datagrams with particularly set IP header areas, while looking for the overall time taken for the response to get to the original transmitter.

ICMP messages are generated at the IP layer. ICMP messages are transferred within normal IP datagrams, ICMP messages are usually processed as a special situation, various from the typical IP handling. In several situations, it is necessary to examine the information had in the ICMP message and also output the appropriate mistake message to the application which produced the initial IP packet.
