(Backbone Networks)
You have been hired as a network consultant by an organization called Dwight Motors. Your job is to recommend an elegant solution to support their needs and to address their current problems. The IT manager of Dwight motors wants you to be aware of the following facts:
• The organization has 3 departments. All addresses are assigned using IP.
• Key servers are currently randomly placed in different departments. So a user in one department X reads and writes to file servers in another department Y. Similarly, users in departments X and Y would read mails from a server in department Z.
• The traffic and broadcast storms originating in one department is causing bandwidth saturation in other departments.
• The core of the network is slow and is unable to meet the response time requirements of various critical business applications.
Propose remedial solutions with adequate justification. In particular, in your recommendation you need to suggest the following:
a) Core technology design.
b) Specific LAN technologies to be used in each department.
c) Specific design solutions to address inter-departmental traffic issues. ((600 words)
