Analysis and Design of LAN Networks for XYZ Company Branches

This presentation outlines the LAN network design for XYZ Company, which needs to establish networks in Adelaide, Melbourne, and Sydney. The design includes subnetting for IP address allocation across 63, 53, and 43 devices, respectively, along with inter-branch connectivity using subnet D. The network follows a hierarchical architecture, employing routers, L3 switches, and L2 switches for core, distribution, and access layers, respectively. Wireless access points provide connectivity for mobile devices. The presentation details DNS and DHCP configurations, IP address schemes, and the use of routers, switches, and wireless access points. It also explains subnet classification based on CIDR and the dynamic RIP routing protocol. The presentation concludes by summarizing the network implementation, architecture, topology, IP configurations, subnetting, and network equipment used to meet the company's networking goals. References to related research papers are also provided.
