into the PE instance. This will evolve over time SO that the control and data planes can be completely disaggregated. 3.3.1.3 Management Plane The management plane involves functions, such as orchestration, configuration management, fault and event reporting, and monitoring. These workloads require high resiliency and tend to be cen- tralized. Generally, they support the operations, administration, and maintenance (OA&M) func- tions in the network. Historically, management plane workloads have been vendor proprietary for configuration, fault, and performance management. Even Simple Network Management Protocol (SNMP) (International), which is an open standard, is not interoperable across vendors. SNMP is an Internet-standard protocol for collecting and organizing information about managed IP devices. Going forward, the goal is to move away from proprietary management protocols in favor of data model-driven architectures with open API interfaces. This will dramatically change the way service delivery and service assurance are accomplished across many disparate VFs. A significant shift is to move away from command line interface (CLI) code to support the configuration of network functions (e.g., routers) in the network. The industry is being driven to a common data model for key services such as Ethernet, utilizing a modeling language called Yet Another Next Generation (YANG) (IETF). YANG is a standardized modeling language to define a service construct. For example, Ethernet can be defined by ports and VLANs. Ports are characterized by interface types, speed, tagging or not, etc. VLANs include speed, VLAN tag, QoS parameters, etc. This standard model can then be DPDK is a set of data plane libraries and network interface controller drivers for fast packet processing.
