Growing traffic demands and increasing security awareness are driving the need for secure services. Current solutions require manual configuration and deployment based on the customer’s requirements. In this work, we present an architecture for an automatic intentbased provisioning of a secure service in a multilayer—IP, Ethernet, and optical—network while choosing the appropriate encryption layer using an open-source softwaredefined networking (SDN) orchestrator. The approach is experimentally evaluated in a testbed with commercial equipment. Results indicate that the processing impact of secure channel creation on a controller is negligible. As the time for setting up services over WDM varies between technologies, it needs to be taken into account in the decision-making process.
