ETSI ETSI GS NFV-INF 005 V1.1.1 (2014-12) 61 Scope The present document presents an architectural description of the Infrastructure Network domain of the infrastructure which supports virtualised network functions. It sets out the scope of the infrastructure domain acknowledging the

20、 potential for overlap between infrastructure domains, and between the infrastructure and the virtualised network functions. Its also sets out the nature of interfaces needed between infrastructure domains and within the infrastructure network domain. The present document does not provide any detail

21、ed specification but makes reference to specifications developed by other bodies and to potential specifications, which, in the opinion of the NFV ISG could be usefully developed by an appropriate standards developing organisation (SDO). 2 References 2.1 Normative references References are either sp
