Summary
While network design for many engineers and consultants can be a very boring subject, it is also a main part that contributes to future network operations. Without a well thought out design, a network is bound to have future problems and be much more costly than is required. Putting a little more time and resources into a good network design not only makes the operations of the network easier but also saves money and time on future network troubleshooting and expansions.
Using a Top-Down network design approach allows the network to be more customized to the needs of the specific company. Without this customization, a network has the ability to become more of a hindrance then a help.
