LAN Consulting Plan
Yesterday I was hired by Taylor and Sons Financial Consulting set up a local area network with a firewall for a Windows® network. Taylor and Sons Financial Consulting is a medium-sized company that is physically located on the first three floors of one building. Taylor and Sons Financial Consulting have approximately 100 employees. For this task I will use a traditional systems development life cycle (SDLC) that consist of planning, analysis, design, development,, testing, implementation, and maintenance. During the planning phase I was notified that there are 100 users, and 80 of those users will extensively use10 applications, upon analysis Taylor and Sons Financial Consulting determined that 10 of the employees are clerks and should have read-only access to the databases, and due to security risk a firewall will be installed. The analysis contains the hardware, software, and other equipment that needs to be installed. The hardware that I recommended was 91 personal computers, 9 laptops for the management Taylor and Sons Financial Consulting management buyers will have the exclusive use of the laptops. Each personal computer and laptop will be equipped with a network interface card, and the personal computers will have a standard keyboard and mouse, and a 17-inch CRT monitor. The computers will be equipped with a 2.8 MHz processor, 512 MB of RAM, a CD-RW drive, and an 80 GB hard drive. I recommended that Taylor and Sons Financial Consulting purchase an ink-jet printer for each computer. I also recommended to Taylor and Sons Financial Consulting to purchase three wireless routers, three DSL modems, nine servers, a firewall, and 24 switch’s, six wireless access point’s. I recommended that Taylor and Sons Financial Consulting use the Microsoft Small Business office productive suite (Microsoft Windows, 2009) to handle the need of word processing, and the preparing of presentations as well as preparing spreadsheets. The serves will run the network with the operating system of windows server 08 datacenter (Microsoft Windows, 2009), which will be located in the data center. Each of the other computers will run windows vista business operating system (Microsoft Windows, 2009). The type of network that Taylor and Sons Financial Consulting will use is a client server network with the Star topology in Infrastructure mode because Taylor and Sons Financial Consulting will be accessing wired devices such as printers and a router to access the internet. I would also recommend using wired connections in the offices and cubicles because the wiring is in place already and by keeping as many users connected to the wire network will free up the bandwidth for the wireless users. The wireless router component is a requirement for a wireless network. The average cost of a wireless router is between $14.99 and $1,299. Tiger direct (n.d.), the average costs of the internal, and external modems are of the following internal $9.99 and $79.99 external $24.99 and $264.99 Tiger direct (n.d.), the average cost of a computer is between $139.97 and $5,539.99. Tiger direct (n.d.). There are two types of servers the tower case and the rack mount type, and the average price of the servers are from $299.99 to $5,089.99. Tiger direct (n.d.). The average price of a firewall is from $24.97 to $4,705.99. Tiger direct (n.d.). The average price for a printer is of the following $44.96 to $7,979.99. The average cost of a switch is between $24.99 and $10,149.99. Tiger direct (n.d.) Once the analysis on the network is complete, the network can be designed during this phase. The type of network that I will be installing is a client server network within wired and wireless star topology. The star topology is set up as a point-to-point architecture to allow single wireless devices or nodes, freely communicate with a gateway. The gateway transmits the data directly to a control room point. Star topologies will use the least amount of power of...
