But this is not over yet. Ethernet also requires CRC verification when transmitting data. The network card will CRC check the data packet before sending the data, attaching a 4-byte CRC value to the back of the packet header. At this time, the packet length is no longer 40 bytes, but 64 bytes, which is often referred to as SYN packet attack. The packet structure is as follows:

Through a certain vote algorithm, select one of the remaining slave server nodes to be promoted to Master server node, then automatically modify the relevant configuration and turn on failover.
