ETSI GS NFV-INF 005提供了基础设施的基础设施网络域的体系结构描述 支持虚拟化网络功能。它规定了基础设施领域的范围 基础设施域之间以及基础设施与虚拟化网络之间可能存在重叠 功能。Its还规定了基础设施域之间和基础设施内部所需接口的性质 网络域。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 005 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 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 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).
