Among this complex and vast network system, switches play a crucial role as one of its core components. This article will delve into the functions and applications of switches, revealing the importance of their role as the cornerstone of efficient network construction. I. Basic Functions of Switches A switch, also known as a network switch or Ethernet switch, is a network device used for signal forwarding. It can forward data packets from one network node to another, completing the process of data packet switching and forwarding. Here are the basic functions of switches: 1. Data Forwarding: Efficiently forwards data packets by analyzing the MAC addresses between input and output ports. 2. Physical Topology Management: Automatically generates a network topology map by learning device information in the network, helping administrators understand the network structure. 3. Filtering Broadcast Traffic: Reduces the impact of broadcast traffic on network performance through techniques such as configuring VLANs (Virtual Local Area Networks).
