Re: [I2nsf] Request for Comments on I2NSF Security Policy Translation

["Mr. Jaehoon Paul Jeong" <[e-mail]>]

Hi Frank,
As you know, the open source is dominant these days.
If IETF sticks to a general specification,
its position will get narrower and narrower in future.

To make I2NSF easily be used in the world, I believe the implementation
guidelines of the security policy translation is important and useful.
IMHO, without these guidelines, but with data models, I2NSF will not be
hard to be accepted.

As long as I understand, I2NSF Applicability draft should focus on how to
leverage I2NSF with other important aspects (e.g., SDN, SFC, and NFV) for
the deployment of I2NSF rather than the detailed specification of I2NSF
components, such as security policy translator.

I2NSF other people,
Let us know your opinions.

After collecting opinions and making consensus, let's move forward.

Thanks.

Paul
