contention slot

contention slot

(Or contention period). Minimum time a host must transmitfor before it can be sure that no other host's packet hascollided with its transmission. If the maximum propagationdelay from one host to any other is T, then a host that startsto transmit at time t0 may collide with a host that startsjust before t0 + T. The first host will not detect thecollision until time t0 + 2T.
