Paul, Thanks for pointing out the RFC that only describes Implementations.
As a Gen-Art Area Directorate, I was asked to provide comments to IESG for draft-ietf-sidrops-rpki-tree-validation-02, which is also to describe an implementation. So there are multiple precedence of have implementation reference published as RFC. (Well the final saying is at IESG at the end).

In our security policy translation draft, we can focus on the mapping from high-level security policy into low-level security policy along with the architecture of an exemplary translator. Thanks.

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.

Although it’s a good example of how to translate the YANG models, but it’s just one of the possible system implementations, thus not suitable to be a specification. My suggestion is you can consider to include its key contents into the I2NSF applicability draft. B.R. Frank 发件人: I2nsf [mailto:[email protected]<mailto:[email protected]>] 代表 Diego R.

But I am afraid I don’t see this document progressing in the standards track (even as an experimental one), as the particular techniques for implementing the translation do not seem a proper subject for standardization. The only place I could see room for it in would be as part of the applicability draft, and I am not sure about it… What do others think?

One important functionality of the Security Controller is to automatically translate an I2NSF User's high-level policy to a low-level policy for NSFs. In the past of our I2NSF Hackathon projects, we made an XSLT-stylesheet-based translator. But this translator has two limitations, such as static capability-and-NSF mapping construction and inefficient maintenance on such a mapping. The first limitation is the difficult high-level policy construction. By the XSLT-stylesheet approach, I2NSF User MUST manually selects target NSFs to execute the required security capabilities. This means that I2NSF User needs to know each NSF's capabilities, so it is difficult for I2NSF User to construct a high-level security policy without the detailed knowledge on NSFs. The second limitation is an inefficient maintenance on the policy translator. If the data models on I2NSF NSF-facing Interface requires some updates, the XSLT stylesheet and XML files need to be updated. On the other hand, our new approach provides I2NSF User with an efficient maintenance. To solve these two limitations, our draft proposes an automata-based policy translator. This translator consists of three components, such as Extractor, Data Converter, and Generator. First, when a high-level policy is delivered from I2NSF User to Security Controller, Translator extracts data about the policy at Extractor, and then converts it at Data Converter for NSF(s). Also, Data Converter can select proper NSFs automatically. Finally, Generator generates low-level policies of target NSFs based on the data from Data Converter. I believe that this draft is valuable for IP2NSF WG adoption to facilitate the development and deployment of I2NSF in the real world. Please read this draft and give our authors your valuable comments. We aim at making this proposal as an Informational RFC. Thanks.
