Design and Implementation of a Scalable Network Infrastructure for a Mid-Sized Organization

This research work encompasses the design and implementation of an efficient, scalable network infrastructure for a mid-sized organization in a two-story building, servicing at least 20 employees. Each employee shall have one wired and two wireless access points to satisfy the need for seamless connectivity for all individual and group activities. All infrastructures are carefully optimized for performance, scalability, and security to meet the divergent needs for administrative, IT, staff, and client operations. It is fundamentally a hierarchical network topology that assists in increasing segmentation and simplifies traffic management by utilizing Virtual Local Area Networks. This hierarchy further provides improved performance, security, and further segregates the traffic between different departments and functions. The infrastructures also integrate redundancy mechanisms in their design for minimal downtime assurance of high availability and reliability of the services. The research work has a robust network monitoring system to ease the operation efficiently and solve issues with minimum delay time. The given IP addressing plan and switch port allocation have considered any future scalability, organizational expansion, and further technological advancement. QoS policies will be configured to prioritize mission-critical business traffic, while a comprehensive security framework, including timely updates, security review, and employees' training on security matters, will fortify the network against changing threats. It provides a highly robust, secure, and future-ready networking for medium-sized enterprise businesses that can assure continuity and evolution of operations, keeping pace with the demands an increasingly digitized, connected world throws up.
