There is a tendency to discount the network as simple plumbing — to believe that the only design considerations 
are the size and the length of the pipes or the speeds and feeds of the links, and to dismiss the rest as 
unimportant. Just as the plumbing in a large stadium or a high-rise building is designed for scale, purpose, 
redundancy, protection from tampering or denial of operation, and the capacity to handle peak loads, the 
network requires similar consideration. As users depend on the network to access the most important 
information that they need to do their jobs and to transport their voice or video with reliability, the network must 
be able to provide resilient, intelligent transport. The reliable network design also needs to incorporate versatility 
in order to address the changing needs of an organization. 
Here are some key concepts that you should address when creating a reliable and versatile network design. The
