Benefits of a Hierarchical Network There are many benefits associated with hierarchical network designs. Scalability Hierarchical networks scale very well. The modularity of the design allows you to replicate design elements as the network grows. Because each instance of the module is consistent‚ expansion is easy to plan and implement. For example‚ if your design model consists of two distribution layer switches for every 10 access layer switches‚ you can continue to add access layer switches

Network Topology and Wiring Tiearia Fariss NTC/361 Professor: Larry Schreider December Network Topologies are the different arrangements that contain many different element such as links‚ nodes‚ etc. This helps with communication and network information processing. This is a major part of today’s technology and is used by big business as well as for home and personal use. There have been eight different network topologies that have been recognized though out a study.. Throughout this paper
