Mn621 Advanced Network Design Assignment 1

This assignment requires designing a comprehensive local area network (LAN) for an expanding e-commerce organization that has recently merged with two smaller entities and is moving into a new three-floor building. The report must analyze the organizational network needs, propose a suitable network design, detail the setup of network devices for the LAN, provide configuration instructions, and demonstrate at least two configurations on physical devices.

Paper For Above instruction

The rapid expansion of organizations, especially those rooted in e-commerce sectors, necessitates robust and scalable network infrastructure to support increased operational demands. The case study involves a company moving into a new building with three floors, accommodating about 100 employees post-merger. Ensuring seamless connectivity, adequate data points, and wireless access across all levels is critical for maintaining operational efficiency and supporting future growth.

Analyzing the current organizational context highlights various network requirements, including wired connectivity at each employee workstation, wireless access across all floors, independent network segments for different departments or areas, and sufficient bandwidth to handle the organization's digital activities. The expanded organization needs a structured network design that guarantees high availability, security, scalability, and efficient management.

The proposed network design leverages hierarchical architecture principles, integrating core switches, distribution layers, and access switches to ensure logical segregation and optimized traffic flow. Core switches will manage high-speed routing between different floors, while distribution switches provide connectivity points for multiple access switches located in offices and workspaces. Wired connections will utilize category 6 (Cat6) Ethernet cables to support gigabit speeds, suitable for data-heavy e-commerce operations.

Wireless access points (WAPs) will be strategically installed to ensure comprehensive coverage, with considerations for interference mitigation and capacity planning to support multiple concurrent users. Network security is paramount, thus incorporating VLANs, firewalls, and access control policies to restrict unauthorized access and safeguard sensitive data.

The network device setup involves selecting appropriate hardware components such as managed switches (e.g., Cisco Catalyst series), wireless controllers, firewalls, and routers, each with specified models and port configurations. Cabling will comprise Cat6 Ethernet cables, and server and client specifications will reflect current enterprise standards to support requisite software and data processing needs.

The network diagram visually depicts the interconnected hierarchy, with clear labels for devices, links, and logical groupings. This visual aid forms the foundation for detailed configuration steps, including setting IP schemas, VLAN segmentation, trunking protocols, and wireless SSID configurations to facilitate secure and efficient network operations.

Configuration commands for each networking device will be documented methodically, illustrating setup procedures for VLANs, routing protocols, port configurations, security settings, and wireless parameters. These commands will be demonstrated physically on the devices, showing the practical implementation and verification of network functionalities.

Furthermore, the report will compare two configurations—such as VLAN implementations on switches or routing configurations on routers—to illustrate their effects on network segmentation, security, and performance. Demonstrating these configurations on physical devices will validate the theoretical planning, with explanations of how each setup enhances the network's overall performance and reliability.

Adhering to IEEE referencing style, the report will cite authoritative sources on network design principles, hardware specifications, and configuration best practices to support recommendations and ensure academic rigor.
