Protocol Layering
The Internet Protocol (IP) divides the tasks necessary to route
and forward packets across networks by using a layered
approach. Each layer has clearly defined tasks, protocol, and
interfaces for communicating with adjacent layers, but the
exact way these tasks are accomplished is left to individual
software designers. The Open Systems Interconnect (OSI)
seven-layer model has been adopted as the reference for the
description of modern networking, including the Internet.
A diagram of the OSI model is shown below (note that this is
not a complete listing of the protocols contained within each
layer of the model):
Figure 5-8. OSI Seven Layer Network Model
Each layer is a distinct set of programs executing a distinct set
of protocols designed to accomplish some necessary tasks.
They are separated from the other layers within the same
