摘要

光突发传输网络是一种新型的城域网WDM环网结构。它利用光突发交换和WDM环的优点，同时使用基于令牌的介质访问方案。本文研究了保护与空间再利用的关系。具体来说，我们展示了OBT中的保护与传统保护的不同之处，并提出了三种算法来实现快速低成本的单向1:1保护方案。我们通过仿真分析了这些方案的性能，找到了在故障期间最小化数据丢失和最大化数据传输的最佳算法。

Protection and Spatial Reuse in Optical Burst Transport (OBT) Networks

Optical Burst Transport network is a novel WDM ring architecture for Metropolitan Area Networks (MAN). It leverages the advantages of optical burst switching and WDM rings, while using a token-based medium access scheme. In this paper, we investigate protection together with spatial reuse property. Specifically we show how protection in OBT can be different from conventional protection and propose three algorithms for implementing a fast and low implementation cost, unidirectional 1:1 protection scheme. We analyzed the performance of these schemes via simulation and found an optimum algorithm for minimizing data loss and maximizing data delivery during the fault.
