中文摘要：

在核心的技术联网妨碍光爆炸切换的实现(OBS ) 的关键问题之一由于在在核心节点的爆炸之中的竞争是损失。爆炸分割是过去常减少由于爆炸损失失去的包的数字的一种有效竞争决定技术。在我们的工作，在 OBS 网络的爆炸分割偏转路由竞争决定机制被建议。当竞争发生时，爆炸第一根据网络的最低的包损失概率被分割，然后分割的爆炸在最佳路由上被偏斜。一个分析模型被建议评估竞争决定机制。高优先级的爆炸举办的模拟结果表演显著地降低包损失概率和传播延期比低优先级。并且爆炸长度，片断的数字几何上每爆炸在散布的表演，比确定地分布式的爆炸长度的更有效。

英文摘要：

One of the key problems to hinder the realization of optical burst switching （OBS） technology in the core networks is the losses due to the contention among the bursts at the core nodes. Burst segmentation is an effective contention resolution technique used to reduce the number of packets lost due to the burst losses. In our work, a burst segmentation-deflection routing contention resolution mechanism in OBS networks is proposed. When the contention occurs, the bursts are seg- mented according to the lowest packet loss probability of networks firstly, and then the segmented burst is deflected on the optimum routing. An analytical model is proposed to evaluate the contention resolution mechanism. Simulation results show that high-priority bursts have significantly lower packet loss probability and transmission delay than the low-priority. And the performance of the burst lengths, in which the number of segments per burst distributes geometrically, is more effective than that of the deterministically distributed burst lengths.
