Among this architecture, switches play a pivotal role as the core device of the enterprise network architecture. I. The Role and Function of Switches Switches are network hardware devices primarily used to connect and transmit data within a Local Area Network (LAN). They enable the interconnection of network devices through high-speed packet switching technology. In a complex network environment, switches effectively manage and control network traffic to ensure rapid and stable data transmission. II. The Importance of Switches 1. Improving Network Performance: Switches have high-speed data processing capabilities, which can greatly improve network transmission speed and response time, thereby enhancing the efficiency of enterprises. 2. Optimizing Network Structure: By connecting multiple network devices, switches can build a more flexible and scalable network architecture that meets the constantly changing needs of enterprises. 3. Ensuring Network Security: Switches can implement access control and data filtering to effectively prevent unauthorized access and malicious attacks, ensuring the security of enterprise networks. 4. Simplifying Network Management: By centrally managing, configuring, and monitoring switches, network administrators can easily manage and maintain the entire network system.
