2. Data Transmission: Switches can quickly and efficiently transmit data, improving network performance. In large enterprise networks, switches can connect multiple subnets, enabling cross-regional data transmission. 3. Network Management: Switches usually have rich management functions, such as port mirroring, traffic statistics, access control, etc., which help enterprises achieve secure network management and optimization. III. Elements for Selecting Switches 1. Performance: When selecting a switch, performance should be the first consideration. Performance mainly includes the switch's bandwidth, backplane bandwidth, packet forwarding rate, etc. These performance parameters will directly affect the network's transmission speed and stability. 2. Scalability: Enterprise networks often require continuous expansion, so it is crucial to choose a switch with good scalability. Scalability includes the number of ports, modularity, etc. 3. Security: Network security is a focus for enterprises. Choosing switches with security features such as access control, VLAN partitioning, port isolation can help improve network security. 4. Maintenance and Support: Choose a switch brand with good after-sales service and technical support so that problems can be resolved promptly when encountered. 5. Cost: While considering factors such as performance, scalability, and security, cost must also be considered. Choose switches that offer a good cost-performance ratio and fit within the enterprise's budget.
