Servers +ISP connections

 Total 130 computers

Following requirements are given by the Management;

•       All the departments must be separated with unique subnet and should not communicate with each other unless there is a special requirement.

•       192.168.10.0/24 is given and should be used for all the departments except the server room. IPs should assign using DHCP. 

•       ERP and CRM Systems need to be implemented in Kandy branch in local servers.

•       Number of servers required for the Server room need to be decided by the

Network designer and should be assigned with 10.254.1.0/24 subnet. (Uses static IPs)

•       High level of redundancy is expected in network design to eliminate single point of failures and traffic bottle necks.

•       Sales and Marketing Team need to access Network resources using WIFI connectivity.

•       Proper methods for networking monitoring and troubleshooting need to be established (intelligent hub).

•       All possible network security mechanisms should be implemented.

Assume you have been appointed as the new network consultant of VIDCO-19 Solutions. Prepare a network architectural design and implement it with your suggestions and recommendations to meet the company requirements. 

 

(Note: Clearly state your assumptions. You are allowed to design the network according to your assumptions, but main requirements should not be violated)

 

Task 01

1.1           Discuss the different network models/system types that can be implemented in Kandy branch with their benefits and constraints.

1.2           Discuss main IEEE Ethernet standards that can be used in above LAN and WLAN design?

1.3           Critically analyze network protocol suites used in Network Industry and recommend suitable network protocol suites for above scenario and justify your selection. 

1.4           Explain the difference between Logical topology and Physical topology using examples and compare main network topologies used in network design. 

1.5           Recommend a suitable network topology for above scenario and justify your answer with valid points.

 

Task 02

2.1     Discuss the operating principles of network devices that can be used for above scenario. 

                Ex: Router, Switch, Etc.

2.2     Explore and describe the devices which we can use to enhance security of VIDCO-19 Kandy Branch.

2.3     Critically analyze the importance of networking software and provide examples for networking software can be used in above network design.

Servers that are available in today’s market with their specifications and Recommend server/servers and workstations for above scenario and justify your selection with valid points.

2.5     Discuss why it is important to have compatible devices and related software in network design.

 

Task 03

3.1      Provide VLAN and IP subnetting scheme for above scenario to satisfy user requirements. 

3.2 Provide a list of devices, network components and software need to design a network for above scenario and justify your selection.

3.3 Provide a detailed network design (Diagram) for your design using modeling tool. (Ex: Microsoft Visio).

3.4 Design a User feedback form and get feedback from network users and analyze their feedback and suggestions.

3.5 Install and configure Network services and Applications* of your choice to accomplish above user requirements. (Ex: DHCP, DNS, Active Directory, Proxy, Web, Etc.)

(Note: Screen shots of minimum 2 services are required)

3.6                  Design a detailed Maintenance schedule for above Network design.

 

*Note: - Screen shots of Configuration scripts should be presented.
