OOPS! The correct answer is "Management and network orchestration"

Management and Network Orchestration (MANO) is one of the critical components of NFV. Features such as container-based micro-services architecture, TOSCA templating, BPMN integration, and support for a host of standards and open-source code bases are key capabilities to look for in a NFV service orchestration solution. These capabilities simplify business and network transformation with SDN and NFV. Ciena’s Blue Planet supports all of these component capabilities.
