Explanation:
Explanation
The Nokia NSP Model-driven Mediation (MDM) framework is based on the YANG data model, uses the NETCONF protocol, and provides an abstracted view of the network element. However, it is designed to be vendor-specific, meaning it is designed to only manage Nokia equipment.
It provides an abstracted view of the network element is FALSE regarding Nokia's Network Services Platform (NSP) Model-driven Mediation (MDM) framework. MDM provides a way to interface between the Nokia NSP and network elements from different vendors. It is based on the YANG data model and uses the NETCONF protocol to provide configuration and management capabilities for network devices. However, MDM does not provide an abstracted view of the network element. Instead, it translates the native configuration of the network element into a standardized YANG model, allowing the NSP to manage the network element in a vendor-agnostic way.
According to the NSP NSD and NRC 18.6 Planning Guide1, Model-Driven Mediation (MDM) is a component within the NSP architecture that provides mediation between model-driven NSP applications and Nokia or third-party network devices. MDM provides an adaptation layer which uses adaptors to convert NSP application requests to device specific directives using standard protocols such as NETCONF, SNMP and CLI over SSH or Telnet12. MDM also provides an abstracted view of the network element3.
