Service provisioning in multi-domain SD-EONs

This work investigates the service provisioning in multi-domain software-defined elastic optical networks (SDEONs) by taking advantage of the centralized network control and management (NC&M) provided by OpenFlow (OF). We design two control plane frameworks, and discuss the corresponding service provisioning schemes in them. The frameworks are also implemented and experimentally demonstrated in a multi-national control plane testbed that consists of two SD-EON domains in China and USA, respectively.
