The present document presents the architecture of the Hypervisor Domain of the NFV Infrastructure which supports deployment and execution of virtual appliances. The present document will primarily focus on the use of hypervisor for virtualisation, due to time and resource constraints, However, the hypervisor requirements are similar if not the same for implementing linux containers or other methods for virtualisation.
 
NOTE: From WikiArch: "Linux Containers (LXC) are an operating system-level virtualisation method for running multiple isolated server installs (containers) on a single control host. LXC does not provide a virtual machine, but rather provides a virtual environment that has its own process and network space. It is similar to a chroot, but offers much more isolation".
 
There needs to be further research w.r.t to Linux Containers, including developing the ecosystem.
 
As well as presenting a general overview description of the NFV Infrastructure, the present document sets the NFV infrastructure and all the documents which describe it in the context of all the documents of the NFV. It also describes how the documents which describe the NFV infrastructure relate to each other.
 
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).
