Enterprise networks today demand high-speed, reliable, and scalable data connectivity to support mission-critical applications, industrial automation, and inter-departmental communication. This paper presents the deployment and performance evaluation of a Gigabit network implementation carried out across a large-scale manufacturing environment, integrating Layer-2/Layer-3 switches, structured cabling, network monitoring systems, and security components. The work involves the design and rollout of a structured optical-fiber backbone, switching infrastructure, IP addressing and VLAN segmentation, and the integration of tools such as HP OpenView Network Node Manager, Gauntlet Firewall, Microsoft Proxy Server, and DNS/DHCP services. Performance measurements indicate sustained throughput in the 900+ Mbps range, forwarding rates above one million packets per second, end-to-end latency below 3 ms, and packet-loss levels under 0.001%. These results demonstrate that a well-architected Gigabit infrastructure can significantly improve operational efficiency, network visibility, and security posture in industrial environments. The paper also discusses deployment methodology, challenges encountered, monitoring strategy, and recommendations useful for similar enterprise-scale network rollouts
