slot time

In Ethernet and its Carrier Sense Multiple Access/Collision Detect (CSMA/CD) approach to managing which device can use the communication link next, slot time is the amount of time a device waits after a collision before retransmitting. The transmitting device determines the appropriate amount of slot time by adding the amount of time it took for another device to detect a collision, the amount of time it took for the device to notify the original transmitting device of the collision, and the amount of time it took to transmit a jam sequence.� Should a second collision occur, the device doubles the slot time in an effort to avoid future collisions; this process is called "backoff". In half-duplex Ethernet, where data can only travel in one direction at once, slot time becomes an important parameter in determining the how many devices can share a network.
