Figure 2 – High level layering of cloud-based network management functional architecture

Figure 2 shows the high level layering of cloud-based network management functional architecture, which
include the following three layers:
– Managed network layer: it indicates the layer containing all the network element functions (NEFs)
that are to be managed. The NEs providing the NEFs can be the traditional telecommunication
network elements, or elements in a cloud infrastructure.
– Perception and control layer (P&C layer): it indicates the perception function blocks and the NE
controlling function blocks. Perception function blocks have the capability to collect the
configuration information, running status, or the performance data from the NEFs, and the NE
controlling function blocks can be able to make necessary reconfiguration or modifications to NE
parameters, through interactions with the specified NEFs.
– Management service layer: This layer mainly contains the network management function blocks,
which provides management services to network operators.
