ETSI GS NFV-INF 003提供了基础设施的计算和存储域的体系结构描述 支持虚拟网络功能（VNF）。计算域包括网络和I/O接口 需要连接到基础结构网络和存储网络（如果有）。它规定了基础设施领域的范围，承认基础设施之间可能存在重叠 域，以及基础设施和虚拟化网络功能之间的连接。它还规定了接口的性质 基础架构域之间和计算域内需要。本文件未提供任何详细规范，但参考了 根据NFV ISG的意见，NFV ISG可以通过 适当的标准制定组织（SDO）。

ETSI GS NFV-INF 003 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).
