摘　　要：提出了一种解决不同优先级突发包之间资源竞争的方案,分析了该方案下不同优先级的性能(时延和丢包率).研究结果表明高优先级突发包的平均时延和丢包率都远小于低优先级突发包,因此该方案能为高优先级突发包提供很好的QoS保障.A novel prioritized scheme applied to contention resolution was proposed for optical burst-switched networks. Performance analyses show that our proposed scheme works very well. The average delay and the burst loss probability of the higher-prioritized bursts are much less than those of the lower-prioritized bursts. The scheme can provide the good guarantee of QoS for optical burst with vital data and information.
