The Network Virtualization Overlays (nvo3) working group in the Routing Area of the IETF is undergoing rechartering. The IESG has not made any determination yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg at ietf.org) by 2014-10-13. Network Virtualization Overlays (nvo3) ------------------------------------------------ Current Status: Active WG Chairs: Matthew Bocci <matthew.bocci@alcatel-lucent.com> Benson Schliesser <bensons@queuefull.net> Secretaries: Sam Aldrin <aldrin.ietf@gmail.com> Technical advisors: Ron Bonica <rbonica@juniper.net> Assigned Area Director: Alia Atlas <akatlas@gmail.com> Mailing list Address: nvo3@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/nvo3 Archive: http://www.ietf.org/mail-archive/web/nvo3/ Charter: 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 environment. 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 protocols.
