Abstract

Examples may include techniques for monitoring virtual network functions or network functions virtualization infrastructure. Examples include receiving performance measurement data from virtualized network functions arranged to support a network service or from network functions virtualization infrastructure composed to support the virtualized network functions. In some examples, corrective actions such as virtualized network function lifecycle management operations are initiated based on the received performance measurement data.
