Abstract

An optical burst switching (OBS) system and a method using duplicate optical burst transmission is provided. In accordance with the present invention, optical bursts do not have the same priority when the duplicate optical bursts are transmitted in an OBS network so that a burst loss rate due to blocking can be reduced. Optical bursts do not have the same priority when the duplicate optical bursts are transmitted in an OBS network, so that a burst loss rate due to the blocking can be reduced. After an optical burst control packet is transmitted on a signal channel using a unidirectional reservation manner in the OBS, a problem such as optical burst loss due to the blocking can be prevented even when the optical burst is transmitted on a data channel after an offset time is elapsed without any response messages.
