Omplete Computer Network Infrastructure for a Real or Ficticious Business

Create a business scenario as the basis for the project. Within that scenario, define at least 20 related network research topics.

Examples of business scenarios:
A multi-campus school system which is looking to reduce costs by using Linux for some of its back office activates. The school system is considering using wireless on its campuses which consists of multiple buildings. (Example: a college with multiple sites across the state, or a college system with campuses in several states)
A banking firm which has decided to grow from a small regional bank into a multistate banking concern. It plans to accomplish this by buying and merging other similar regional banks into its operations. These other banks of course have different IT infrastructures which must be integrated into the final solution, which would result in a heterogeneous network.
A national business which is planning on establishing a web-based presence and is expanding into the international marketplace. It plans on opening a website and on opening offices in a few select foreign cities. In keeping with the local custom in those countries, it plans on using Linux in those locations.

Identify the necessary components of the network and design both local and wide area networks to support the system. Choose and justify the network equipment, network services, protocols, servers, software services and back office connections. Design the infrastructure to support the various back office platforms and services each business would require.
A Visio diagram or similar would be useful as well to show the layout of the network design.
