This chapter describe how a hierarchical network supports the voice, and data needs of a small- or medium-sized business. Describe the functions of each of the three levels of the hierarchical network design model, the principles of hierarchical network design, and the concept of a converged network. Provide examples of how voice and video over IP affect network design,...

When building a LAN that satisfies the needs of a small or medium-sized business, your plan is more likely to be successful if a hierarchical design model is used. Divided into discrete layers. Each layer has a specific purpose. Becomes modular – maintenance, performance.Interfaces with end devices. Routers, switches, bridges, wireless access points. Provides a means of connecting and controlling which devices are allowed to communicate on the network.

Data Model: A set of concepts to describe the structure of a database, and certain constraints that the database should obey. Data Model Operations: Operations for specifying database retrievals and updates by referring to the concepts of the data model. Operations on the data model may include basic operations and user-defined operations.

The minimum number of Cs that can be associated with one A is 1. I know this because the existence of the C to A relationship is mandatory. The maximum number of Cs that can be associated with one A is unlimited (or many). I know this because the cardinality of the C to A relationship is 1-M.

Describe how a hierarchical network supports the voice, and data needs of a small- or medium-sized business. Describe the functions of each of the three levels of the hierarchical network design model, the principles of hierarchical network design (aggregate connectivity, network diameter, and redundancy), and the concept of a converged network. Provide examples of how voice and video over IP affect network design.

Objectives: Describe how a hierarchical network supports the voice, and data needs of a small- or medium-sized business. Describe the functions of each of the three levels of the hierarchical network design model, the principles of hierarchical network design (aggregate connectivity, network diameter, and redundancy), and the concept of a converged network. Provide examples of how voice and video over IP affect network design. Select appropriate devices to operate at each level of the hierarchy, including voice and video components.
