Hi Camilo,

We have looked into the question of groupings when preparing version -07, which 
tries to address other last call reviews (see 
https://datatracker.ietf.org/doc/html/draft-ietf-tcpm-yang-tcp-07 or 
https://www.ietf.org/rfcdiff?url2=draft-ietf-tcpm-yang-tcp-07). Yet, we decided 
not to introduce groupings in -07.

We would like to first better understand the actual use case in your model. Why 
would the BMP yang model indeed use exactly the same definitions of “common”, 
and “statistics” sections of ietf-tcpm?

The counters in statistics typically apply the whole TCP stack, not to an 
application. Why would your model not use application-specific events instead?

Also, the exact status of a TCP connection as seen by the TCP stack will 
typically not matter to the application. Note that this part of the model also 
has changed in -07 because of other review comments. Would your model indeed 
want to include e.g. the internal state of a TCP connection?

Note that it is possible that a follow-up version -08 will be required due to 
other reviews, i.e., we could look at this question in a version -08 again.

Thanks

Michael

Subject: How to reuse the tcp model in the BMP model - asking for suggestions

Hello draft-ietf-tcpm-yang-tcp authors,

We are analysing how to leverage the tcpm model for managing tcp connectivity 
in the BMP yang model (draft-cptb-grow-bmp-yang-02).

In general, how do you suggest other models reuse ietf-tcpm? Most of tcpm model 
is defined directly in containers, not as groups, and we are finding hard to 
take the pieces that we need.

Let us shortly gointo details.

Regarding the 4-tuple connection, in BMP, we would like to have a “default” 
case in which the configured device connects to another using ip/port (i.e. 
active case),  but also to provide the option of expecting the  tcp connection 
over a local ip/port (i.e. passive case). We might need our own container for 
this.

However, we would like to integrate the “common”, and “statistics” sections of 
ietf-tcpm, but, they are containers, so we really do not know what to do 
besides recreating it.

Do you have any suggestions?

Thanks,
draft-cptb-grow-bmp-yang authors
