h can be off-boarded to the SDN-Mon VM, is summarized below: Service performance monitoring using active measurement techniques Service reachability monitoring using active measurements Control plane monitoring instrumentation utilizing passive observations Analytics applied to raw information generated by network elements (e.g., packet stats, flow stats), with resulting KPI generation Bump-in-the-wire type monitoring for "sniffing" packets passing between network edges Deep packet inspection techniques applied to captured packets To summarize, decoupling these measurement functions from the network elements allows for consolidation of these functions into a common SDN-Mon VM.

Building the Network of the Future optimization of measurement instrumentation by eliminating overlapping functionality, resulting in simplifying the overall measurement solution. In addition, this approach also allows us to procure the measurement technologies from entities that specialize in such, rather than relying on network element developers, whose priority is to ensure that the network element meets its core functional definition first. 16.5 AT&T's SDN-MON FRAMEWORK AT&T's SDN-Mon defines a common framework that allows for decoupling of all inorganic (syn- thetic) measurement functions from network elements, and encapsulates them within a common framework that appears to ONAP just like any other managed network element would. The encapsulated diverse set of measurement functions in the SDN-Mon framework is shown as measurement ag
