2 FMA Goals and Objectives 1. FMA enables the standardization of the complete disaggregation of the CCAP management, control, and data planes (SDN, NFV, and PNF) 2. Defines standard interfaces between OSS/NMS/Orchestration to FMA s management plane (manager) and control planes (SDN Controller) as well as a standard interface abstraction layer to cable access equipment New / existing CMTS, Edge QAM, PON equipment (RMD, RMC, pcore, vcore, vcmts, vccap, volt, polt, R-OLT, etc.) 3. Defines an open standard interface specification based on a data modeling language (YANG) for a single abstraction layer used by all FMA access equipment suppliers 4. FMA enables vendor independence and interoperability FMA defines SDN Management and Control Interface Standards for existing and new OSS/NMS as well as Cable Access Equipment

8 FMA Key Points FMA is defining the Headend Re-architected as a Datacenter (HERD) and the standard interfaces Northbound interfaces will work existing MSO back-office systems and will migrate to next generation systems with new interfaces Southbound interfaces are based on RESTCONF/YANG for a single abstraction layer used by all FMA access equipment suppliers Specifications are underway and YANG data model releases will align with specification release schedule
