Possible Architecture

Given a typical deployment featuring Network Management Software (NMS), Figure 1 displays a high-level view on the typical components and the information flow between them. The NMS needs to implement vendor-specific interfaces in order to accomplish configuration tasks by communicating with the control plane of forwarding elements. In case of monitoring, standardized protocols like SNMP can be used.

In contrast, Figure 2 illustrates an SDN-based infrastructure and its possible integration with an NMS. Since the control plane interaction is handled by the logically centralized SDN controller, the NMS can contact the SDN controller through the northbound API when configuration and SDN-specific monitoring tasks need to be performed. Monitoring in general could still be performed via SNMP or Netflow.
