You’re bound to the physical conditions of the transmission medium. The slot time describes the length of time a signal may take to the end of the collision domain and back again.ĭata in networks, however, is not sent through empty space at the speed of light. This results in a slot time of 51.2 μs (microseconds). The smallest data package, which accordingly takes the shortest time for complete transmission, and is the most extreme case, has a size of 512 bits (64 bytes). If you assume you’re dealing with a classic half-duplex Ethernet network, this has a data transmission rate of 10 Mbps. With this knowledge and the information about the network technology being used, the maximum size of a collision domain can be calculated. If no other participant tries to send its data via the medium by the end of transmission, and no collision occurs, the transmission has been a success.
Meanwhile, the transmitter continues to monitor the transmission medium to see if it detects any data collisions.

Only when the medium is free and for a certain time (in interframe spacing), will the station send a data packet. As long as this is occupied, the monitoring will continue. First, the station monitors the transmission medium.
If we happen to start talking to someone else at the same time, we stop our attempt, wait a bit, and then try again. Without realizing, we actually behave like this ourselves in conversations: When someone else is talking, we stand back and listen.Īfter the other participant has finished their contribution for the time being, we wait a short time and only start talking when the same participant or another participant in the conversation doesn’t start to say anything else. Instead, they should speak one after the other, so that each participant can fully understand what the others are contributing to the discussion. The procedure is based on a normal group conversation: for good communication, it is important that the participants don’t all speak at once, which can be confusing.
