| 摘 要： | 为了解决光突发交换中突发包竞争问题，针对光突发网络中现有的突发包分割机制，提出新的基于优先级分组复合封装策略，分析冲突长度相对值和偏射路由阈值概念，结合头部丢弃与偏射路由双重机制进行冲突解决。仿真结果表明，该策略有效地较低了网络的丢包率，保证了高优先级IP包的高效传输，较好地支持了网络的QoS。

| Abstract: | For contention resolution in OBS, this paper proposes a new priority-based Grouping and Hybrid-Assembly(GHA) policy, which is combined with head-dropping and deflection routing scheme. Simulation results demonstrate that this policy reduces packets loss probability, especially the packets with high priority, so that, it can be well used in the optical burst switched networks with QoS requirement. |

| Keywords: | Optical Burst Switching(OBS) GHA policy segment dropping deflection routing |
