Network Design Project
For CTC company that wants all its offices and departments networked, I would first recommend star WAN topology to connect all its offices. The headquarters in Washington DC will be the central point of connection with the other offices which is located across the U.S. This type of topology will best suit the company because first, it is very reliable because even if one site fails, data can still be rerouted so it would not affect the entire network system. Second is that this topology provides shorter data paths when all of its circuits are functioning. This means that data gets from one point to the other faster. Third is that expansion costs less. If for example, CTC wants to open another office in Florida, all it needs to do is to lease another dedicated circuit from Washington to Florida and none of the other offices would be affected by the change. The sites would be connected through the Internet and the way of achieving this is by T1 carriers. T1 would best suit this company because of the reasonable cost of installation and monthly service fees. Coaxial cable will used to accommodate multiple T1 connections. Also with the T1 connection, the terminal equipment will consist of bridges, routers, or a combination of two.
The four divisions in the headquarters, which are Administration, Sales and Marketing, Consulting, and Training, each will have hubs that would connect to the main router. For all four divisions in the headquarters, I would suggest using a parallel backbone topology because these would be the critical aspects of the business that cannot afford to lose connectivity. Parallel backbone topology consist of more than one connection from the central router to each network segment so it ensures network connectivity to any area of the enterprise. It will be a little expensive but it will make up for the additional cost by offering increased performance. Each of the workstations will be connected to a hub, which will then connect to the central file server. For the cables that will be used, I would recommend CAT5 cables simply because of its reliability and cost factor. For the field offices in New York, San Francisco, Los Angeles and Atlanta, which employs about one hundred people at each site, I would suggest a star topology on their LAN with hubs that connect to each workstation. Because of the number of workstations it will support, using a few hubs will make a big difference as far as reliability is concerned. The smaller field offices which are Philadelphia, Chicago, Seattle, and Dallas will also have a star topology network but with
