Simple understanding of Ethernet Switch Telecom/Datacom Systems
The working process of Ethernet Switch Telecom/Datacom Systems can be summarized as "learning, memory, receiving, table lookup, forwarding" and other aspects: through "learning", you can know the MAC address of the device connected to each port; The corresponding relationship with the port number is "memorized" in the memory, and the MAC address table is produced; after the data frame is "received" from a port, the port number corresponding to the destination MAC address in the frame header is "searched" in the MAC address table, Then, the data frame is "forwarded" from the found port.
Ethernet Switch Telecom/Datacom Systems divides the collision domain, and each port independently forms a collision domain. If each port has a large amount of data to send, the port will first store the received data waiting to be sent into the register, and then send it out when it is the turn to send.
