Hierarchical Model
A hierarchical model is a modular design for an enterprise network that defines three specific layers that each has network services associated with those layers. The layers are access, distribution and core. The access layer is associated with branch offices that usually run lower speed circuits. These branch offices are aggregated at a distribution office and several distribution offices are aggregated at a core office. Modular designs are more scalable and utilize bandwidth more effectively than flat networks.

Overview
A network assessment is conducted after we have finished the business and design requirements of the company. A network assessment provides a quick snapshot of the current network with an examination of the infrastructure, performance, availability, management and security. That information is utilized for making effective strategy recommendations and design proposals to the client concerning specific information systems modifications before implementing wireless network equipment.
Network Assessment Components
The current network is examined using 5 primary surveys: infrastructure, performance, availability, management and security. When the surveys are completed, the information collected is then reviewed for trends, problems and issues that are negatively affecting the network. The surveys are reviewed and compared with best practices, business requirements and design requirements. The results from the analysis are then utilized to develop specific recommendations that focus on design, equipment configuration, security and network management strategy improvements. As well the information is used to support the design process.
