Solution Approach 1:

The patent introduces an intermediary monitoring system that sits between the virtualized network functions and the infrastructure resources. This intermediary collects performance metrics from virtualized functions and translates them into meaningful infrastructure performance data, resolving the complexity of directly monitoring virtualized environments while maintaining adaptability benefits

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback mechanisms where performance metrics are continuously collected from virtualized network functions and fed back to the monitoring system. This feedback loop enables real-time detection of performance degradation and facilitates proactive management of virtualized resources, addressing the monitoring difficulties introduced by virtualization

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple new components, interfaces, and technologies are deployed simultaneously in NFV, then service capability and adaptability are improved, but difficulty of detecting and measuring performance increases
