摘　　要：在光突发交换(OBS)网络的数据信道调度算法中,多采用抢占策略来解决QoS问题,从而导致了大量已预留资源的浪费。提出并探讨了一种预留失败后可及时释放已预留资源的解决方案,并给出了各控制分组和核心节点处资源预留表项的格式,最后分析了其可行性。In OBS networks most algorithms of channel allocation are based on preemptive mechanisms, which could easily leave behind a lot of useless occupied resources. A new scheme is proposed to release those unused bandwidth. Also discussed are the formats of two control packets, as well as its feasibility.
