Layer 3, Network: IP, ICMP, IGMP, ARP
Layer 4, Transport: TCP, UDP
The TCP/IP suite operates at layer 2, and layer 3 of the TCP/IP model as follows:
Layer 1, Link: ARP
Layer 2, Internet: IP, ICMP, IGMP, ARP
Layer 3, Transport: TCP, UDP

Objective: Network Concepts
Sub-Objective: Describe the operation of the following: IP, TCP, UDP, ICMP
