Hi Bill,

That would make an MPLS tag an "address". Somehow I don't think so.
Why not? What characteristics of what you think of as an address are
missing from the typical use of an MPLS tag?
Well, for one thing, an MPLS label is relative. Label value X is only
meaningful pairwise between a pair of routers along the path. The same
value X between any different pair of routers will imply a separate LSP
and thus a different path entirely.
(Not to
mention the TOS field, if anyone is still using TOS-dependent routing.)
Was TOS ever used in the dynamic part of a routing protocol?
Yes. OSPF used to have TOS support.
If we really need a name for some particular crisp definition (such as the
one above), pick a new word/phrase, don't try and morph an existing word.
If the chair is amenable to that idea, so am I. At the moment I'm
endeavoring to remove the fuzz from the existing terms as the chair
requested.
Normally, I would love that idea. However, our specific request is that
we define the terms locator and identifier.
Regards,
Tony
