波长变换对光突发交换网络性能的影响

Influence of wavelength conversion technology on the performance of optical burst switched networks

介绍了光突发交换原理及波长变换技术。模拟了基于美国国家科学基金网络模型的光突发交换。数据源选用具有自相似性的突发性数据源,采用JET(Just-enough-time)信令协议,使用LAUC-VF数据信道调度算法。为减小竞争的发生,在网络中加入波长变换器。对带波长变换器和不带波长变换器的网络的性能进行了模拟,并对结果进行了分析。

The technology of optical burst switching and wavelength conversion is introduced. We simulate the optical burst switching based on NSFNet network. We choose self-similar traffic as source, JET signaling protocol and LAUC-VF scheduling mechanism. In order to decrease the burst loss probability, we add wavelength converter to our network. We simulate the OBS network with and without wavelength converter, and contrast the result and analyze it.
