Dear NVO3 Contributors - This message initiates a 1 week last call for comments on the proposed charter. The charter has been discussed on the mailing list for about a month, and the chairs believe there is consensus to go forward with the current text. We intend to submit the proposed charter text to the IESG on 10-Sep-2014. The proposed charter text is found at http://svn.tools.ietf.org/svn/wg/nvo3/charter-ietf-nvo3-01-rev-20140901.txt and is quoted below.
Just a reminder, this last call is not an opportunity to vote. Please do not waste time on messages that merely say "support" or "+1". Rather, this is an opportunity to raise any material issues or feedback that has not yet been addressed on the mailing list. Matthew and I are thankful for everybody's contribution to the charter discussion, and we look forward to making progress in the next phase of the NVO3 WG. Cheers, -Benson & Matthew http://svn.tools.ietf.org/svn/wg/nvo3/charter-ietf-nvo3-01-rev-20140901.txt 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 using an IP-based overlay approach. An NVO3 solution provides layer 2 and/or layer 3 services for virtual networks enabling multi-tenancy, workload mobility, optimization, management, and security, addressing the issues described in the problem statement 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 or more control plane protocols to support the architecture. Such protocols are expected to fulfill the communication requirements between an End Device and Network Virtualization Edge (NVE), 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. BGP-based solutions to network virtualization within a data center environment will be developed in the BGP-Enabled Services (BESS) WG.
