Abstract :
This work studies how to take the advantage of the centralized network control and management (NC&M) provided by OpenFlow-controlled software-defined elastic optical networks (SD-EONs) for online spectrum defragmentation. We design a control plane framework, and conduct control plane experiments in an SD-EON testbed to demonstrate the effectiveness of the framework. Experimental results indicate that the framework can improve the network performance in an effective way.
