光突发交换及其冲突解决协议

The Principles of Optimal Burst Switch and Its Contention Resolution Protocol

光突发交换是一种介于光路交换OCS和光分组交换OPS之间的很有发展潜力的交换模式,它融合了两者的优势又克服了两者的缺点。首先介绍了光突发交换的概念,并讨论了光突发交换最为关键技术———竞争问题。重点阐述了光突发交换网络的竞争解决方案及光突发交换网络的恰量时间协议。

Optical Burst Switching （OBS） is a new and promising switching paradigm, which can combines the best of the optical circuit-switching and the optical packet-switching paradigms while avoiding their shortcomings. The basic concept, principles, network and node architecture of OBS are presented. The hot topic of OBS-Contention Resolution and Just Enough Time protocol is also given out.
