Assignment Task -                 
 

Objectives:  
By completing this assignment, 
A)Logical network design for a typical SME  
B)IP address planning  

Background:  
A private software company, called Soft.com, is opening its new offices in Brisbane and Gold coast,  Australia to sell healthcare products. Their main product is a system (software) that provides a variety of health services. The managing director has asked for a "software development company of the future, using the latest technologies with a network which can accommodate the load now and for another five years and leaves room for further expansion, The company's headquarter (HQ) will be located in two adjacent three-story buildings (Buildings A and B)  in Brisbane. The distance between the buildings is 20m.

Table 1: Hosts Information Table  
Where XYZ is the last three digits of your student ID. If any of these three digits is Zero  (0), you replace them with the next non-zero number in your ID to estimate each department's host size. 
Software Development and Marketing will be in Building A with the other three departments are in Building  B. All the workstations, printers, and other devices will be connected through the wired network. There will be support for Bring Your Own Device (BYOD). The server farm (3 or more servers) can be located in  Building A. There must be a direct connection between the two buildings. The edge router (the router that will be connected to the Internet and provide internet access to the organization) will be located in Building B. 

Future  
Future aspiration is to change the culture of the workplace. The employees and management particularly want to enable working from home for the software development team. In this regard, it is expected that all software developers will be issued with Laptops/MacBook Pro, which they can take home. The company will also need to increase its resources to support the new online services. The production process will also be updated.  The production team will need 50 new computers to control the 3D printers. The administration department will be adding 7 more workstations and 2 printers to handle the extra workload. The company also wants to be more open and allow BYOD, but it does not want to compromise security. The company also needs to connect with a WAN at a branch office (Gold Coast), located approximately 100km from the HQ of the company. The Gold Coast branch has only two departments: software development  (25 hosts) and marketing (6 hosts). They need to be linked to the software development company's HQ network.  

The main objectives for the proposed solution are:  
• A modern network for the company  
• More accessibility without compromising on security  
• Support for online services  
• To ensure that this company has video conferencing between the main office and its branch &The network is proposed to achieve the above objectives considering the company's following business and technical goals.  
Business goals:  
• Improved communications, wireless, videoconferencing, etc.  
• Spare no expense,  
• Protect company information,  
• The company of the future will have at least a 30% increase in staff in two years,  

• Be excellent in technology.  
Technical goals:  
• The current network, computer rooms are to be upgraded to a modern network (campus design) to  meet developers and employee's needs,  
• Scalability – remember they want to expand for the next five years,  
• Availability – Wireless network access is available in all employees as well as some outdoor areas  for software developers and employees,  
• Employees have access to company resources from both company and home (different servers),  

• Performance – network performance must be high,  
• Reliability – no single point of failure,  
• Security – protection of company information and other IT assets,  

Note- You are required to design a recommended network for the Company's HQ (main branch) LAN based on the current and future user network requirements and the WAN link to the Branch office. 
 

What you need to do  
You are required to design the network you would recommend. Remember, the goal of building a new network is that it will support the company's needs for the next five years. Your recommendations are to be submitted as a formal report containing your analysis of the present situation and your recommended network solution. You are free to make any further assumptions you wish.  
In your report, you are required to:  
i. Analyse user network requirements.  
ii. Suggest a type of network architecture that is suitable for the organization. You will need to identify all the media (circuits), network hardware necessary to build the network(s) you are proposing and to justify your choice, i.e., you will need to explain the function of the hardware and network choice in your solution and to justify your choice by value for Money, Quality of  Service (QoS), security, etc.  
iii. Each department should have a separate wired LAN. This is for security reasons. The departments should still be able to communicate with each other.  
iv. All department LANs need to support voice, video, and data communication. They all also need access to a printer(s).  
v. There also needs to be wireless access throughout the floor for all the workers to connect their own devices. The wireless LAN should be secured, so no person from outside the organization uses it.  
vi. Explain the IP address plan for the proposed network.  
vii. Explain logical network design with diagram(s) for the proposed network.  

viii. Draw a physical network(s) diagram that shows how you connect the hardware you have chosen in (ii).  
ix. Designing/selecting a WAN connection to provide fast, reliable but inexpensive and secure  Internet access.  
x. There should include an application for video chat for the workers as well as email.  

xi. The network design needs to leave room for 30% expansion both in terms of bandwidth (data rate) and the number of users.
