Internet Control Message Protocol
ICMP is a protocol that works alongside IP as a form of messaging protocol in order to compensate for the limited reliability of IP. The implementation of ICMP is required to be understood to familiarize with the behavior of numerous operations and applications that rely heavily on ICMP, in order to support underlying messaging, based on which further processes are often performed.
The objectives of this class:
Upon completion of this section, you will be able to:
Describe some of the processes to which ICMP is applied.
Identify the common type and code values used in ICMP.
Explain the function of ICMP in the ping and traceroute applications.
