Assignment Brief
EMC Solutions is a private owned well-known Software company located at Colombo. The Management of EMC Solutions decided extend their services Kandy and as a result building with 3 stories has purchased in the heart of Kandy town. They are planning make it to become one of the state-of-the-art companies in Kandy with new facilities.

They are expecting have nearly 150 employees in Kandy branch. Following requirements are given by the Management;
» All departments must be separated with unique subnet and should not communicate each other unless special requirements are given.
» 10.254.1.0/24 is given and should use for all the departments except Server Room. IPs should assign using DHCP.
» Server Room and SAN should be in J 92.168.1.32/27 subnet. (Uses static IPs)

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

» Multiple ISP connections need to configure for gateway redundancy.

» Link aggregation need to configure to improve the Network performance where necessary.

» Data transmission between Head office and Kandy need to be secured with proper WAN design.

» Sales and Marketing Team need to access resources at Kandy office and the head office securely while they are in 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. Part 1
Explore LAN design principles and their application in the network design process.
