ICMP Statistics
Internet Control Message Protocol (ICMP) is a network layer protocol that
transmits message packets to report errors in processing IP packets. ICMP
is therefore an integral part of the Internet Protocol. ICMP messages may
be used to report various situations, such as when a datagram cannot reach
its destination, when the gateway does not have the buffering capacity to
forward a datagram, and when the gateway can direct the host to send
traffic on a shorter route. ICMP is also used by routers to feed back
information about more suitable routes (i.e., the next hop router) to use
for a specific destination.
