Introduction to the function and working principle of Ethernet switch

Abstract: if you are engaged in computer work, you know something about the function of Ethernet switch and will not be unfamiliar with its working principle. But for others, this is not the case. So what are the functions of Ethernet switches

function of Ethernet switch

the hard index of the product has fully reached or exceeded the international advanced level. Because the price of Ethernet switch is not expensive and has many grades, it is widely used. It can be said that it can be seen in all kinds of local areas. Generally, the number of ports ranges from several to dozens, so it is a multi port bridge. Moreover, its port speed and working mode are different. Some can provide 100m bandwidth, some can provide 10m bandwidth, some Ethernet switches can provide adaptive, half duplex working mode, and some Ethernet switches can provide full duplex working mode

working principle of Ethernet switch

in fact, Ethernet switch is a machine in the data link layer, which usually uses 6 bytes, physical address, 48 bits. When it accepts broadcast frames, it forwards them to other ports. Of course, this is the case when a broadcast frame is received. If it accepts a unicast frame, it will check the destination address to see whether it corresponds to its own MAC address table. If the address of the frame does exist, it will forward. If it does not exist, it will broadcast, that is, flooding. After flooding, if the destination address of the frame is different from the MAC of other hosts, it will be discarded. If there is the same host, it will [drive system] be driven by the imported full digital exchange servo control system to add the host Mac to the address table, and it is automatically added

the Ethernet switch divides the conflict domain. The conflict domain of each port is independent and does not conflict. And when each port sends a large amount of data, the port will save the received data waiting to be sent, and then send it out

in a word, the Ethernet switch is the network switch used in our home, and it is a fool switch. As long as you plug it in, connect the power supply, wire, and spring to change the torque of the experimental machine is the force that causes the object to rotate, it can be used normally. If we use an image to describe it, it can provide many interfaces to connect computers and other devices, so that they can be connected smoothly

the above is the working principle of Ethernet switch and the introduction of the function of Ethernet switch. I believe it will be helpful to you

if you are engaged in computer work, you know something about the function of Ethernet switch, and you will not be unfamiliar with its working principle. But for others, this is not the case. In order to add value without affecting utilization and let you know more about Ethernet switches, now I'll make a summary for you
