Description of the Company/Case:
 

Dreamz Inc. develops software and learning solutions for clients worldwide. The main office of the organization is located on six floors of a building in Chicago where 100 users occupy each floor. While the first floor houses the corporate office, the other floors house the Administrative, Finance, HR, Engineering, Marketing, IT, and Research departments. All users need e-mail, file and print, and Internet services. To provide these services, the organization has 10 servers that are used as LAN, proxy, and database servers. The users in the finance and HR departments require sufficient bandwidth and access applications from an Oracle server. This server is accessible to users only in the finance and HR departments; these users can also access the server from the Internet. Dreamz Inc. is also connected to the Internet from the same network and has Web and e-mail servers hosted for Internet access. With expanding business, Dreamz Inc. has setup three branch offices in St. Louis, Detroit, and New Jersey. These three branch offices need to be connected to the main office and other branch offices. Another fourth office at San Francisco comprises a network of five users and requires a single Internet connection.
