As organizational reliance on digital infrastructure intensifies, optimizing network performance becomes paramount. Network switches, serving as critical nodes in data transmission pathways, play a vital role in ensuring efficient, reliable, and scalable network operations. This paper conducts an in-depth exploration of network switch technologies and strategies for optimizing network performance. It examines various types of switches, including Layer 2, Layer 3, and multilayer switches, alongside advanced technologies such as Software-Defined Networking (SDN) and network virtualization. The study employs a mixed-methods approach, combining a comprehensive literature review with empirical analysis through case studies in diverse environments like enterprise networks and data centers. Key performance metrics—throughput, latency, packet loss, and scalability—are analyzed to identify best practices and optimization techniques. The findings highlight the significance of strategic switch deployment, configuration, and management in achieving superior network performance. This research provides actionable insights for network administrators and IT professionals aiming to enhance their network infrastructure's efficiency and adaptability in the face of evolving technological demands.
