• 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 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.
