Network Models
Network models provide a standard framework to use when designing complex communication systems.
These models outline standard issues associated with network design and allow the designer to solve each issue separately, modularizing the solution.
A network model is a framework to use, not a concrete method. It is up to the implementers to decide which parts of the model are relevant to accomplish their goals.
Different networks can be described functionally as belonging to one of these three broad categories:
Peer-to-peer networks,
Client/server networks, and
Wireless.
Let us look into the details of each of these models now.
