1. Connection Role The most basic function of a switch is to connect. In the network architecture, switches connect various network devices such as computers, servers, routers, etc., through wired or wireless means, forming a vast network system. This connection allows information to flow freely between devices, enabling resource sharing and interoperability. 2. Improving Network Efficiency Switches exchange data through the data link layer, enabling rapid data transmission. When a device needs to send data to another device, the switch can quickly find the MAC address of the target device and send the data packet accurately to the target device, avoiding resource waste caused by data broadcasting across the entire network. Additionally, switches support multiple transmission modes such as full-duplex and half-duplex, which can be flexibly configured according to actual needs to further improve network efficiency. 3. Enhancing Network Stability Switches have high reliability and stability, effectively ensuring the normal operation of the network. When a fault occurs in the network, the switch can quickly switch to an alternate path to ensure network connectivity. Additionally, switches support various network management functions such as port mirroring and traffic statistics, which can help network administrators quickly detect and resolve network issues, enhancing network stability. 4. Flexible Network Topology Switches support multiple topology structures such as star, ring, and mesh, which can be flexibly configured according to actual needs. This flexibility allows the network architecture to be more versatile and adaptable to different scales and demand scenarios. 5. Value Manifestation In the network architecture, the value of switches is mainly reflected in the following aspects: firstly, they can improve the speed and efficiency of network communication; secondly, they can enhance the stability and reliability of the network; finally, they provide rich management functions and tools for network administrators to help them better manage and maintain the network.
