摘要 光突发交换网络被认为是一种新的IP over WDM网络，也是下一代互联网的发展趋势。 该文给出了一个在光突发交换网络中解决多跳分割丢弃不公平性的改进方法，该方法不但保留了原有方法的可以保证多跳网络中数据包丢失率的一致性优点，而且还减小了损失，增大了网络吞吐量。最后通过仿真验证了该方法的有效性，对实际网络的设计有一定的理论指导意义。
Abstract：Optical burst switched network has been proposed as a new network scheme which can realize IP over WDM and also been regarded as the trend of the next generation network. An improved method has been proposed to solve the unfairness of burst segmentation or dropping in optical burst switched multi-hop network, this approach not only could maintain the advantage of original approach, which could make the packets loss probability coherence in multi-hop network but also could decrease the losing and increase the throughput. Finally, a simulation proves the validity of the proposed method and it has the theoretic meaning to design the real network in practice.
