By adding such a platform to the NFV ecosystem, new business models emerge as we discuss in this article. ...
We tackle this challenge by introducing the novel concept of a verification and validation (V&V) platform for NFV, which enables automatic testing and qualification of single network functions and complex ...
To answer this question, we take a closer look at a typical NFV scenario shown in Fig. 1 . It shows a network service, consisting of four VNFs that are chained together to form an SFC. ...
