policy-driven automation of management functions. The metadata-driven service design and creation capabilities enable ser- vices to be defined with minimal IT development required; thus contributing to reductions in CapEx. The real-time OMF provides significant automation of network management functions enabling the detection and correction of problems in an automated fashion contributing to reductions in OpEx. One of the challenges for service providers in a traditional telecommunications environment is that unique and proprietary interfaces are required for many network management systems (NMS) and element management systems (EMSs); these lead to significant integration, startup, and opera- tional costs, and standards evolve slowly in this space. As the service provider industry transitions to this new network cloud environment, there are plans to continue contributing to and leveraging code within the open source community; this approach facilitates agile and iterative standards that incorporate incremental improvements. In the network cloud ecosystem controlled by ONAP, the goal is to rapidly onboard vendor VNFs with standard processes, and then, operate these resources via vendor-independent controllers and standard management, security, and application interfaces. Configuration and management is Building the Network of the Future model-driven and will utilize new standards as they become available. To this end, the network cloud should support open-cloud standards (e.g., OpenStack, TOSCA, etc.) and support cloud and network virtualization industry initiatives and protocols (e.g., NetConf, YANG, OpenConfig, OPNFV, etc.). As further standardization occurs, ONAP will incorporate these, as appropriate. 7.1.1 OPEN NETWORK AUTOMATION PLATFORM ONAP enables product- and service-independent capabilities for design, creation, and lifecycle management. There are many requirements that must be met by ONAP to support this new network cloud vision. Of those many requirements, some are key in supporting the following foun
