Re: [nmrg] draft-irtf-nmrg-autonomic-network-definitions-01 feedback

Hi, Olivier,

In the definition draft, we have defined the terms of autonomic network (which probably should be changed into the "partial autonomic network") and the "full autonomic network". What you mentioned is refering to "full autonomic network".

Dear benoît and colleagues,

I would like to comment on your point #1: Logical OR between the functions.

If one considers Autonomic as defined in the original paper, and how it is experienced on various use cases, the functions must be all there to have a real « autonomic » system.
I recommend the reading of work we did a couple of years ago on network renumbering with R. Droms and how the different self-* features when combined, lead to a real autonomic system.
The paper which was published in IEEE Communications Magazine can be found at in a draft version: hal.inria.fr/inria-00531215/PDF/

Best Regards,

/Olivier Festor
