Network Design:

Classic Catalog Company runs a small but rapidly growing catalog sales business. It has outsourced its Web operations to a local ISP for several years but as sales over the Web has become a larger portion of its business; it has decided to move its Web site onto its own internal computer systems. It has also decided to undertake a major upgrade of its own internal networks. The company has two building: an office complex and a warehouse. The 2-story office complex building has 20 computers. The first floor has 10 computers devoted to telephone sales. The company expects to add another 5 telephone sales computers over the coming year. The warehouse, located 400 feet across the company's parking lot from the office building, has about 100,000 square feet, all on one floor. The warehouse has 5 computers in the shipping department located at one end of the warehouse. The company wants to experiment with using wireless handheld computers to help employees more quickly locate and pick products for customer orders. Based on traffic projections for the coming year, the company plans to use a T1 connection from its office to its ISP, but wants to make sure that the network is designed to be easily expandable should traffic increase more rapidly than expected. It expects to need at least three servers: the main Web server, an e-mail 2 server, and an internal application server for its application systems (e.g., orders, payroll).

Design the network with best practices. Please provide a diagram and be sure to include the devices and type of network circuits you would use, and explain why.
