An energy efficiency scheme based on the coordination of management and control is proposed to reduce the power
consumption in multi-domain WSON. Experiments are conducted on the energy efficient multi-domain WSON testbed
(EEMWT) to assess the performance of the scheme.
In optical networks, fault detection is an important aspect of network management system, also a prerequisite to the protection/restoration process triggered when abnormal conditions or break-downs of links or nodes happen in the networks. The ever-growing development of optical networks, such as the division of domains and the diversity of the techniques, protocols and administration policies adopted by different network operators, challenges the traditional fault localization methods applied in single domain networks. This paper investigates the fault localization problems for single-domains, and then extends it into multi-domain optical networks. A Multi-Domain Layered Fault Localization (MD-LFL) Model is proposed to address this problem. And then its application scenario is presented to show its effectiveness by sub-dividing the computational complexity among domains and introducing cooperative diagnosis between domains.
