reservation technology

Reservation methods are conflict-free access methods for networks in bus topology.

In contrast to token procedures or collision procedures, with the reservation technique certain time intervals are reserved for each station wishing to transmit. The transmission times can be calculated in advance by the transmitting stations.

In the reservation technique used in Distributed Queue Dual Bus( DQDB), for example, the data stations announce their desire to transmit, and then wait for the reserved container in which to store their data. Such reservation techniques can operate statically or dynamically in nature.
