Well, I am not sure what you mean by "compression"...



The template mechanism that I was referring to is (briefly) described in slides 11 and 12 of slides-120-netmod-10-bbf-liaison-on-management-at-scale-projects<https://datatracker.ietf.org/meeting/120/materials/slides-120-netmod-10-bbf-liaison-on-management-at-scale-projects>



In figurative terms, the slides say that:

The actual data nodes of an instance to be configured are internally generated from a “photocopy” of the data nodes of an original configuration (template, green dots on slide 12) that is customized here and there (cf blue dots on slide 12) for this specific instance. The gain in the running data store size is that

  *   only one copy of the many green dots of one (or say, a few) templates need to be persistently configured and stored on the device
  *   only a few blue dots need to be persistently configured and stored on the device, different for each instance (many ones)



Best regards,

Robert

Then, if the market sees virtue in it, I think that it would make sense to propose modules to standardization to make templates a deployable reality.



Is “template mechanism” just a weird way to say “compression”?



We know how to do the latter.
