In the context of modern data communication, designing a network that effectively demonstrates interconnectivity and communication between multiple devices is fundamental. This assignment involves creating a detailed network diagram, providing IP address assignments, explaining the underlying wireless, LAN, and WAN technologies, detailing remote access mechanisms such as VPN, and offering step-by-step device configuration instructions. This comprehensive network design not only illustrates technical concepts but also emphasizes practical implementation, ensuring effective data exchange within and across networks.

Network Topology and Design

The designed network comprises two distinct networks—Network A and Network B—connected via a router that facilitates inter-network communication. The topology consists of a single router that connects two switches; each switch manages three hosts, three of which are designated as servers. One network contains either a Web Server or an FTP Server but not both, ensuring diversity in server deployment.

The physical layout includes:

• One router connecting to two switches via Ethernet links
• Each switch connects to three hosts via Ethernet cables
• Wireless routers integrated into each network to enable wireless connectivity for hosts
• Connected servers (Web or FTP) within one of the networks to demonstrate hosting services

The diagram illustrates hierarchical placement of devices, ensuring efficient data flow and scalability. The topology ensures that all hosts can communicate both within their networks and across networks through the router, simulating real-world enterprise network scenarios.

Wireless, LAN, and WAN Technologies

The network leverages several key technologies to ensure seamless data transmission and connectivity. For Local Area Networks (LAN), Ethernet cabling and switches are used, providing high-speed, reliable connections within each network. The wired LANs operate on standards such as 1000BASE-T (Gigabit Ethernet), facilitating efficient data transfer among hosts and servers within each network.

On the wireless front, the network incorporates Wireless routers compliant with IEEE 802.11ac standards, enabling high-speed wireless connectivity (up to several hundred Mbps) for mobile and stationary hosts. Wireless LANs allow hosts to connect flexibly without depending solely on wired infrastructure, enabling mobility and ease of access, especially for remote or wireless-enabled devices.

For Wide Area Network (WAN) connectivity, the router connecting Network A and Network B utilizes serial or Ethernet connections, representing the internet or private data links. The WAN technology ensures secure, robust inter-network communication, often employing protocols like MPLS or VPN tunnels for remote access and secure data exchange. VPN technology is critical for establishing encrypted connections over public networks, ensuring secure remote access for users within the organization.

Remote Access and VPN Connectivity

Remote users and hosts can connect securely via Virtual Private Network (VPN) or remote desktop applications. VPN creates encrypted tunnels over the internet, protecting data confidentiality and integrity during transmission. Users can connect through VPN clients configured with device-specific or client software, authenticating via credentials and establishing secure links with the network perimeter.

These VPN connections enable seamless access to local resources, files, or services as if connected locally. For example, users in remote locations can access the web server or FTP server securely, facilitating remote management, data transfer, and collaboration. The VPN technology employs protocols like IPsec or SSL/TLS, depending on organizational policies and network infrastructure.

Remote desktop applications like RDP or VNC can also be employed for direct host control, offering real-time interaction with network devices or workstations, especially for administrative tasks or troubleshooting.

Configuration Steps for Devices

The device configuration process involves several systematic steps to ensure network connectivity, security, and functionality:

1. Router Configuration: Assign an IP address (200.1.19.1 for Network A, 199.10.19.1 for Network B), enable routing protocols such as OSPF or EIGRP for dynamic routing, configure interfaces, and set up NAT if needed. Establish routing rules for inter-network communication.
2. Switch Configuration: Configure VLANs if necessary, assign switch ports to appropriate VLANs, enable Spanning Tree Protocol (STP) for loop prevention, and configure trunk links between switches and routers.
3. Wireless Router Configuration: Assign wireless network names (SSID), configure security protocols like WPA2/WPA3, set IP addresses, and enable wireless interfaces for both networks.
4. Server Setup: Configure IP addresses, subnet masks, and default gateways. Set up web hosting or FTP services as per requirements.
5. Security Configurations: Implement ACLs to restrict access, configure firewall rules, and enable VPN server settings for remote user access.

The detailed command-line configurations depend on device models and vendor-specific operating systems, but the overall process follows these structured steps to ensure comprehensive network functionality.

Testing and Results

Connectivity tests involve using commands like ping to verify device reachability, ftp for file transfer tests, and browser-based access to verify web server connectivity.

Ping tests demonstrate that hosts across different networks can reach the router and each other, with successful replies indicating proper configuration. FTP login and file transfer tests confirm server accessibility and correct setup of services. Browser access to the web server verifies HTTP/HTTPS configurations and makes sure the web services are functional.

Figures and screenshots (not included here) would typically show successful pings, FTP sessions, and browser-based web page loads to validate the network's operational status.

Conclusion

This comprehensive network design showcases the integration of wired and wireless technologies to facilitate seamless communication within and across networks. Proper IP address planning, technology selection, VPN configuration, and systematic device setup are essential for creating a secure, reliable, and efficient data communication environment. Such a network model serves as a foundation for expanding organizational infrastructure and implementing advanced network services.
