{Sorry I've been silent for a while - been taking a break.} > From: "Templin, Fred L" <Fred.L.Templin@boeing.com> > I have long maintained that what LISP is calling "EID" is not really an > identifier We've been around and around on this many times, and while the first few did I think introduce some useful light, I think we're probably past the diminishing returns at this point? Believe it or not, this is a point on which I do have some sympathy: some people may recognize one of my favourite quotations, which I have used in a number of places: "I am far from thinking that nomenclature is a remedy for every defect in art or science: still I cannot but feel that confusion of terms generally springs from, and always leads to, confusion of ideas." -- John Louis Petit, "Architectural Studies in France", 1854 Was 'EID' the best term to use? Perhaps not (although the difficulty in introducing a new terms should not be ignored). I am moved to mark the irony that while people continually complain over this re-use of the term 'EID', I have yet to hear almost _anyone_ (other than me) complain about the re-use of the term 'locator', which was clearly defined to mean 'location sensitive name _which does not necessarily appear in every packet_' (see Nimrod WG archives: http://mercury.lcs.mit.edu/~jnc/tech/nimrod/1993Sep-Dec.txt where we found that we needed a new word as we found that people couldn't free their minds from the assumption that an 'address' was something which _had_ to appear in every packet - we had at that point yet to grasp that their was an equal difficulty in people being sensitive to the fact that 'addresses' a la IPvN embodied both location _and_ identity - which is yet _another_ example of terminology being warped). So the term 'locator' is continually mis-used in the IETF (see, e.g. RFC-2373 "IPv6 Addressing Architecture", RFC-2956 "Overview of 1999 IAB Network Layer Workshop"), but somehow nobody has a similar-sized problem with that. Why is that? Which is not to say, of course, that one wrong excuses another; multiple definitions can indeed, as Petit observes, cause confusion. But I am somewhat peeved at what I see as disparate treatment in the two cases. > if the node has multiple independent (virtual) interfaces to which LISP > EIDs must be assigned, it is not possible to say that only one of them > is the "identity" of the endpoint Suppose I had an architecture with 'true' EIDS. Suppose further that I assigned a single node multiple 'true' EIDs. Which one is the 'identity' of the node? Noel
