摘要： 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.

摘要翻译： 提供了一种光突发交换（OBS）系统和使用重复光突发传输的方法。 根据本发明，当在OBS网络中发送复制光脉冲串时，光脉冲串不具有相同的优先权，从而可以减少由于阻塞引起的突发丢失率。 当在OBS网络中发送重复的光脉冲串时，光脉冲不具有相同的优先级，从而可以减少由于阻塞引起的突发丢失率。 在OBS中使用单向预约方式在信号信道上发送光突发控制分组之后，即使在偏移时间之后在数据信道上发送光脉冲串，也可以防止由于阻塞引起的光脉冲串丢失等问题 经过没有任何响应消息。
