Re: [Supa] [i2rs] FW: New Version Notification for draft-hares-i2rs-bnp-eca-data-model-03.txt

Joel: 

On #1) the dependency between I2RS Filter-based RIB (FB-RIB) and ECA, please
see draft-kini-i2rs-fb-rib-info-model-02.txt. In section 1.1, it gives the
definition of the FB-RIB.  In section 1.2, it links this to an
event-condition-action model.  If you disagree with the definition of  I2RS
FB-RIB, then we should probably restrict this conversation to the I2RS mail
list.  Any feedback on the Info-model or data-model would be helpful.  The
authors hoped to go to a WG adoption call at the end of this week. 

One challenge for the ephemeral I2RS FB-RIB, is there is no definition of
the non-ephemeral FB-RIB.  If you think there should be a non-ephemeral
FB-RIB - that discussion may be useful between I2RS, Netmod and SUPA. 

On #2) SUPA ECA model, I agree that we should be able to have a common
draft.  At IETF 94, I raised issues regarding the SUPA versus my ECA
definition.   

Cheerily, 

Sue

I think there are two issues here.

1) It is not clear to me why there is any dependence of the fb-rib data
model on an eca data model.  While supa does allow for policy model to be
sent directly to the router, it also allows many other cases.

2) The approach with the supa eca data model is still under development. 

  Having said that, the material in there is intended to be very general.
>From what I understand, there should be no difficulty in refining the action
side of that model to actions which affect the fb-rib in ways that are
consistent with the fb-dib data model.

Yours,

Joel
