With the rapid development of computers and their interconnection technology (commonly known as "network technology"), Ethernet has become the most widely used short distance two-layer computer network to date. The core component of Ethernet is the Ethernet switch.
Whether it is manual switching or program-controlled switching, it is for the transmission of voice signals and requires exclusive circuit switching. And Ethernet is a computer network that needs to transmit data, so it uses "packet switching". However, regardless of the switching method adopted, the characteristic of the switch providing an "exclusive path" between two points will not change. In terms of Ethernet devices, the essential difference between a switch and a hub is that when A sends a message to B, if it passes through the hub, all network nodes accessing the hub will receive this message (that is, it will be sent in broadcast form), but the network card will filter out information not sent to the local machine at the hardware level; If through the switch, unless A notifies the switch to broadcast, the message C sent to B will never be received (except in cases where the switch control permission is obtained to listen).
Ethernet switch manufacturers have launched three or even four layer switches based on market demand. However, its core function is still Ethernet packet switching in the second layer, with a certain ability to handle IP layer or even higher-level packets. A network switch is a device that expands a network and provides more connection ports for connecting more computers in a subnetwork. With the development of the communication industry and the advancement of national economic informatization, the network switch market is showing a steady upward trend. It has the characteristics of high performance to price ratio, high flexibility, relative simplicity, and easy implementation.
