摘要: 为了降低光突发交换网络中突发包的丢失率、降低网络路径的阻塞率、减小突发包冲突的概率,提出了考虑优先级的突发包碎片可控合并重传算法。当网络中数据通信发生冲突时,该算法能根据优先级进行突发包的分片,核心节点将这一信息反馈给边缘节点,边缘节点根据突发碎片的优先级以一定的概率重传被丢弃的突发包分片;同时,针对由于多次重传导致的突发包碎片过多的问题,该算法还按照突发包碎片的优先级顺序进行碎片重组,大大降低了网络的阻塞率。结果表明,相比以往的冲突解决算法,此算法在网络业务繁忙时的数据丢比特率和网络阻塞率方面的改善作用有比较明显的优势。这一结果对光突发交换网络的网络的性能改善方面是有帮助的。

Abstract: In order to decrease the byte loss probability, guarantee lower path blocking probability and reduce burst contention of optical burst switching(OBS) networks, a novel burst-segment recombination and controllable retransmission algorithm based on priority in OBS networks was proposed. When the burst contention occurred, the algorithm could divide the burst according to the quality of service, the core node would send the feedback information to the edge node and the edge node would combinate the segmentation according to the priority and retransmit the recombined burst with different probability to improve the performance of OBS networks. The design and calibration were verified by simulation results. Compared with the conventional contention control algorithms, the scheme could obviously reduce the path blocking probability and decrease the byte loss probability especially when the network was extremely busy. The study has an important reference on the improvement of OBS networks.
