光突发交换网络的生存性及保护恢复

Survivability and Protection & Restoration in Optical BurstSwitched Networks

光突发交换(OBS)是很有前途的一种光交换方式,其中的保护恢复策略增强了网络的生存性。介绍了OBS的原理、OBS中的保护和恢复机制及其特点,对OBS网络的保护恢复提出了一些技术要求,这有助于OBS网络生存性的真正实现。

Optical burst switching is a promising optical switching technology in which protection & restoration mechanism can enhance network survivability. Firstly, we introduce the principle of OBS. Then, we introduce protection & restoration mechanism of OBS and its characteristics. Finally, we put forward some technique requirement of protection and restoration of OBS, which can guarantee effective realization of OBS survivability.
