[...] Good question. Is this question comparable to IEEE 802.3 interfaces and Medium Attachment Units (MAUs)? In the past, I think we have seen different approaches and I am not sure there is agreement on a common approach. For 802.3 MAUs, MAU details were modeled in data models extending a single interface. For other technologies, interface layering seemed to be more appropriate. It would be nice if there would a common understanding how to model interface specifics consistently but I am afraid we have no common model. The ietf-interfaces module essentially allows both approaches. It leaves it open, however, to decide which approach is appropriate. /js PS: A pure layering approach would treat an IP interface as an interface layered on top of say an IEEE 802.3 interface but the ietf-ip module does not really force this since many implementations do not expose this layering. If I would do a clean slate design, I would likely, from a architectural point of view, go with a layering approach. -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
