Description of Working Group:

  The purpose of the NVO3 WG is to develop a set of protocols and/or
  protocol extensions that enable network virtualization within a data
  center (DC) environment that assumes an IP-based underlay. An NVO3
  solution provides layer 2 and/or layer 3 services for virtual networks
  enabling multi-tenancy and workload mobility, addressing the issues
  described in the problem statement (including management and security),
  and consistent with the framework previously produced by the NVO3 WG.

  The NVO3 WG will develop solutions for network virtualization based on
  the following architectural tenets:
   - Support for an IP-based underlay data plane
   - A logically centralized authority for network virtualization
  Network virtualization approaches that do not adhere to these tenets are
  explicitly outside of the scope of the NVO3 WG.

  In pursuit of the solutions described above, the NVO3 WG will document
  an architecture for network virtualization within a data center

  The NVO3 WG may produce requirements for a network virtualization
  control plane, and will select, extend, and/or develop one protocol
  for each of the functional interfaces identified to support the
  architecture. Such protocols are expected to fulfill the communication
  requirements between an End Device and a Network Virtualization Edge
  (NVE) in cases where the NVE is not co-resident with the End Device,
  and between an NVE and the Network Virtualization Authority (NVA).
  The internal mechanisms and protocols of a logically centralized NVA
  are explicitly out of scope of the NVO3 WG.  Architectural issues
  raised by coexistence of multiple logically centralized control planes
  in the same data center may be considered by the WG. Inter-DC
  mechanisms are not in scope of the NVO3 WG at this time.

  The NVO3 WG may produce requirements for network virtualization data
  planes based on encapsulation of virtual network traffic over an IP-
  based underlay data plane. Such requirements should consider OAM and
  security. Based on these requirements the WG will select, extend, and/or
  develop one or more data plane encapsulation format(s).

  Additionally, the WG may document common use-cases for NVO3 solutions.

  The working group may choose to adopt a protocol or data encapsulation
  that was previously worked on outside the IETF as the basis for the WG's
  work.  If the NVO3 WG anticipates the adoption of the technologies of
  another SDO as part of the selected protocols or data encapsulation, the
  NVO3 WG will first liaise with that SDO to ensure the compatibility of
  the approach.

  The NVO3 WG will not consider solutions to network virtualization
  within a data center environment based on extensions to BGP or LISP
