Consumption Models
===================
-Fig 3.1 shows how a sample application will be provided to demonstrate
-usage. In reality many VNFs will have an existing performance or traffic
-monitoring utility used to monitor VNF behavior and report statistics, counters,
-etc.

-To consume the performance and traffic related information provided within the
-scope of this project should in most cases be a logical extension of any
-existing VNF performance or traffic monitoring utility, in most cases it should
-not require a new utility to be developed. We do not see the Software Fastpath
-Service Quality Metrics data as major additional effort for VNFs to consume,
-this project would be sympathetic to existing VNF architecture constructs. The
-intention is that this project represents a lower level interface for network
-interface monitoring to be used by higher level fault management entities (see
