scope:

The present document presents an architectural description of the compute (& storage) domain of the infrastructure which supports virtualised network functions (VNFs). The compute domain includes the network & I/O interfaces required to interface to the infrastructure network and the storage network, if any.

It sets out the scope of the infrastructure domain acknowledging the potential for overlap between infrastructure domains, and between the infrastructure and the virtualised network functions. It also sets out the nature of interfaces needed between infrastructure domains and within the compute domain.

The present document does not provide any detailed 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).
