Ethernet adopts carrier frame listening multiplexing (CSMA) mechanism with conflict detection. The nodes in Ethernet can see all the information sent in the network, so we say that Ethernet is a kind of broadcast network.
Ethernet works as follows:
When a host in Ethernet is transferring data, it follows these steps:
1. Is there any signal transmitting on the listening channel? If so, indicate that the channel is busy and continue listening until the channel is idle.
2. If no signal is heard, the data is transmitted
3. Continue to listen when the transmission, such as discovery conflict, the avoidance algorithm, random wait for a period of time, and then perform step 1 (when the conflict occurs, the computer that is involved in the conflict will be sent back to the listening channel state.)
Note: Each computer is allowed to send only one package at a time, one congestion sequence, to warn all nodes)
4. If no conflict is found, the send succeeds, and all computers must wait for 9.6 microseconds (run at 10Mbps) after the most recent send, before attempting to send the data again.
