This is a cisco network topology. A network topology is the schematic representation of how the logical and physical components of a communication network are organized. It is the arrangement of links and nodes inside a network and how they relate to one another. Topologies can be divided into two categories: logical network topology, which describes how data is routed via the network between devices, and physical network topology, which relates to the physical signal transmission medium. EdrawMax lets you create a network topology diagram in easy steps.
