Local Area Networks (Lan) At Huffman Trucking

1226 words - 5 pages

Huffman Trucking has created Local Area Networks (LAN) at each of its four locations to help complete day-to-day tasks. A LAN "supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home" (Mitchell, 2010). This paper will examine the current LAN in each facility and make recommendations for improvement.Physical Extent of the LANThe LAN in each facility, Los Angeles, St. Louis, Bayonne, and Cleveland, connects two operations within the facility, office and plant. The Missouri and Ohio networks have identical setups, but the California and New Jersey networks have unique setups. The different setups can be due to the size of the facility and the type of tasks they handle.Nodes and WorkstationsIn any network there are nodes that are connected to the network. A node is "a connection point, either a redistribution point or an end point for transmissions" (What is node, 2006). The nodes that are connected in the Huffman networks are mainly servers, workstations, printers, and routers. Each facility varies in the number of nodes and workstations that are connected to the network. The following table lists the number of nodes and workstation types for each facilityNumber of ServersA server is "a computer designed to process requests and deliver data to other computers over a local network or the Internet" (What is client/server, 2009). The number of servers in a network depends on the amount of data that needs to flow through the network. Servers can be setup to handle specific applications due the amount of data that is needed to run the application properly. For example, the Missouri office has a Lotus Notes Server on its network. This server will handle data specific to the Lotus Notes application.In the table listed below shows the number of servers in each LAN by facility. The California facility has the most servers and the New Jersey facility has the least. This is due to the amount of data that is handled in the California plant. The California plant has a large number of PCs, multiple printers, and a scanner. All of these components create data that needs to be stored and transferred to different locations. The New Jersey facility is a smaller operation so the need for computing power isn't as great.ApplicationsEach computer in the Huffman LAN has applications installed on them. Applications are used to gather data, view reports, or process tasks. Some version of Windows is installed on all of the computers except for the Mac computers used in the Marketing departments in California, Ohio, and Missouri.E-mail is used throughout the Huffman network, but there are two applications that the organization employs to send and receive messages. The Missouri/Ohio facilities have Lotus Notes installed and the California/New Jersey facilities use AOL Mail service.ArchitectureAll of the Huffman facilities have client/server architecture except for the New Jersey facility....
