Course Overview
Synopsis
The Internet Control Message Protocol (ICMP) is a core protocol used by network devices, like routers and hosts, to send error messages and operational information indicating success or failure when communicating with another IP address. This session will explore the structure, types, and real-world applications of ICMP, including how it’s used in diagnostics (e.g., ping and traceroute), how ICMP helps maintain network health, and how it’s handled in modern network security scenarios.
Target Audience
Network engineers.
Pre-requisites
To make the most of this session, participants should have a basic understanding of computer networking concepts, particularly how IP addressing and routing work within a network. Familiarity with the OSI model—especially the network layer (Layer 3)—will help in grasping how ICMP interacts with other protocols. A general awareness of common protocols like IP, TCP, and UDP is recommended. Additionally, prior exposure to network diagnostic tools such as ping and traceroute will provide useful context, though it’s not mandatory.
