Re: [nvo3] Fwd: DRAFT Charter Update for Discussion

["Larry Kreeger (kreeger)" <[e-mail]>]

Hi Benson,

I do think Don's additional text is useful.  I am a little bit concerned with the word "mobility" since I often hear it used in relation to mobile devices (e.g. cell phones).  The problem statement mostly discusses "virtual machine mobility", so I would be more comfortable with that.

Also, "multi-site" seems to be a new expansion of scope and may run up against solutions coming from the L2VPN/L3VPN WG.  Rather than taking that on, perhaps it is better to cover how NVO3 solutions can interwork with L2VPN/L3VPN solutions.

Thanks, Larry

Hi, Don. Thanks for the specific, constructive feedback.

The sparseness was an intentional choice aimed at making the charter more concise. But I'm perfectly comfortable admitting that I may have taken it too far... Your proposed text seems like a pretty good improvement to me.

I'd be interested in hearing feedback from other participants here.

Cheers,
-Benson

The first paragraph seems a little sparse.  One would have to read the problem statement and framework to determine the scope.

My suggestion is expanding something like this:

An NVO3 solution, also known as a Data Center Virtual Private Network (DCVPN), is a set of protocols and/or protocol extensions that address providing both Layer 2 and Layer 3 Services within and between DCVPNs.The issues addressed include virtualization, multi-tenancy, multi-site, mobility, optimization, management and securityas described by draft-ietf-nvo3-overlay-problem-statement consistent with the approach described by draft-ietf-nvo3-framework.

I’d also suggest expanding NVA and NVE acronyms.

Cheers,
Don

Dear NVO3 Contributors -

As discussed during the NVO3 meeting at IETF-90 in Toronto, the chairs have been drafting a new / revised charter for the WG. The latest draft charter text is below for your review.

Frankly, we suspect that some of the wording could be further improved to be more clear and/or precise. With that in mind we ask for your help - please let us know if something seems unclear or if you have suggestions for better wording.

If you have feedback please post it to the list for discussion within the next 2 weeks.

Thanks,
-Benson & Matthew

An NVO3 solution, also known as a Data Center Virtual Private Network (DCVPN),
is a set of protocols and/or protocol extensions that address the issues
described by draft-ietf-nvo3-overlay-problem-statement consistent with the
approach described by draft-ietf-nvo3-framework.

NVO3 will document DCVPN requirements for both control plane protocol(s) and
data plane encapsulation format(s), as well as management, operational,
maintenance, troubleshooting, security and OAM protocol requirements.
Additionally, NVO3 will document common use-cases for DCVPN solutions.

Consistent with the documents described above, the NVO3 WG will document an
architecture for DCVPNs within a data center environment based on the following
architectural design points:
-   A logically centralized NVA control plane
-   Support for an underlay IP data plane between NVEs

Based on this architecture the NVO3 WG will develop one or more NVO3 solutions.
This may include documenting applicability of existing protocols, contributing
to the development of protocol extensions by other WGs and/or SDOs, and/or
developing new protocols as appropriate.

Solutions and/or protocols that were developed outside of the IETF, but not
developed by another SDO, and that have multiple interoperable implementations
may be adopted by the NVO3 WG for further development, based on WG consensus,
if requested by the authors .

If the NVO3 WG anticipates the adoption of the technologies of another SDO,
such as the IEEE, as part of any DCVPN solution, it will liaise with that SDO
to ensure the compatibility of the approach.
