ICMP Internet control message protocol It’s not for data transferring... It really designed for routing. Like to check “Did I drop any packet’s….”                         * It does the error handling in the network                         * It debug the errors and show the message IP protocol had no error reporting or correcting mechanis Who send who recivee….   ICMP messages use the following format   The most important ICMP message types Datagram –        no call setup phase –        more flexible –        more reliable in cases of switching node failures –        difficult to control network’s state and provide quality of service •          Virtual circuits –        network can provide sequencing –        traffic engineering can be applied, enabling more practical provision of quality of service (QoS) support –        less reliable in cases of switching node failure
