The stream of KPI data is stored in a +database, and it is visualized in a performance-visualization dashboard. + +For NFVI characterisation, a fixed test VNF, called :term:`PROX` is used. +PROX implements a suite of test cases and visualizes the output data of the +test suite. The PROX test cases implement various execution kernels found in +real-world VNFs, and the output of the test cases provides an indication of +the fitness of the infrastructure for running NFV services, in addition to +indicating potential performance optimizations for the NFVI. + +NSB extends the Yardstick framework to do VNF characterization in three +different execution environments - bare metal i.e. native Linux environment, +standalone virtual environment and managed virtualized environment (e.g. +OpenStack).
