Hi, Shinobu,

Agree with you that it's a challenge to explain Tricircle and cross OpenStack L2 networking in short. So do you have any suggestion to provide a short but very accurate and clear (concise description) for Tricircle and the feature cross OpenStack L2 networking?

And how to enhance the blueprint to help readers easy to understand?

Best Regards
Chaoyi Huang ( joehuang )

Hi Team,

Since there was no tag [tricircle] in subject, I'm emailing you again.
Sorry for spam -;

We are trying to describe specification [1] regarding to ""cross
OpenStack L2 networking"" [0] as Chaoyi mentioned in previous message.
Honestly that description [0] does not accurately describe what this
project is trying to do. And it's hard to be described by few words as

And he mentioned having a quick look at presentation material. [2]
This is fine to understand this project. But it's still not good enough.
AFAK it's because that those kind of materials are completely based on
our blueprint. [3].

IMHO I would recommend you to start from that blurprint.
At least from:

 7. Stateless Architecture Proposal

If some sentences are not based on that blueprint, that's a problem.

But even you read that blueprint, you do not really understand what
this project is trying to do.
This is a real problem. We have to fix a blueprint first.

Otherwise we face double-writes issue which could cause huge risk to
this project.
