Unit 15 Transport Network Design - Higher National Diploma in Computing

Learning Outcome 1: Explore LAN design principles and their application in the network design process.

Learning Outcome 2: Implement a network using LAN design principles based on a predefined set of requirements.

Learning Outcome 3: Produce an appropriate WAN solution to a set of organisational requirements.

Learning Outcome 4: Solve a range of network related problems using appropriate troubleshooting techniques and methods.

Assignment Brief and Guidance:

EMC Solutions is a privately owned, well-known Software company located in Colombo. The Management of EMCSolutionshas decided to extend their services to Kandy and as a result a 3 stories building was purchased in the heart of Kandy. They are planning to make it one of the state-of-the-art companies in Kandy with thelatest facilities. It is expected to have nearly 150 employees in Kandy branch.

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.
• 10.254.1.0/24 is given and should use for all the departments except the server room. IPs should assign using DHCP.
• Server room and SAN should be in 192.168.1.32/27 subnet. (Uses static IPs)
• High level of redundancy is expected in network design to eliminate single point of failures and traffic bottle necks.
• Multiple ISP connections need to be configured for gateway redundancy.
• Link aggregation need to beconfiguredto improve the Network performance where necessary.
• Data transmission between Head office and Kandy need to be secured with a proper WAN design.
• Sales and Marketing Team need to access resources at Kandy office and the head office securely during the field visits.
• Proper methods for networking monitoring and troubleshooting need to be established.
• Customer Care and Sales team should not be allowed to access the Finance Web server in Kandy server Room.
• All possible network security mechanisms should be implemented
