Development of the network has taken place over the past eight years in a series of steps that involved minimal planning, with the exception of the WAN links, which have been recently redesigned. The current network is characterized by slow response and frequent outages. The engineering department uses a database server located in the engineering building. This server processes heavy local traffic that keeps the local network at 70% of bandwidth. Accounting uses commercial package for general ledger, accounts payable, and accounts receivable; these packages are located on a server in the administration building. This server processes heavy local traffic and light traffic from other buildings. All other servers are located in the information-processing center. All employee use e-mail located on one server in the information-processing center. There is a web server that is available for public use and an internal web server that is available to employees for company news items and for human resource applications, such as an internal jobs-available database.
