Benson and Matthew: Suggestion of the wording:
It would be more clear to have the third paragraph on "In pursuit of the solutions.." right after the bullets under "The NVO3 WG will develop..." because it is a very important deliverable of the WG. Instead of "In pursuit..", I would suggest the following wording: " To have a common baseline for all the solutions to be developed by NVO3, the NVO3 WG will prioritize finishing the architecture document for network virtualization within a data center environment" (because it is already an WG draft. By the way I just noticed NVO3 architecture draft has expired). Some suggestions on the MILESTONES: I think application specific multicast is an important area, especially for data centers whose underlay IP network don't support PIM or traditional L3 multicast schemes. Many data centers fall into this category. Another important area is seamless VM mobility in Data Center environment to avoid sub-optimal routing, as described by draft-ietf-nvo3-vm-mobility-issues-03.txt. Therefore, I think the following items need to be added to the MILESTONES: - VM mobility issues in DC environment submitted for IESG review - Framework & solutions for Application Specific Multicast Adopted by WG.

Below is the latest version for your review. Cheers, -Benson & Matthew http://svn.tools.ietf.org/svn/wg/nvo3/charter-ietf-nvo3-01-rev-20140827.txt An NVO3 solution is a set of protocols and/or protocol extensions that enable network virtualization within a data center (DC) environment using an IP-based overlay approach. It 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 control plane 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.
