RE: Some Comments on ID/Loc Separation Proposals

["Tony Li" <Tony.Li@procket.com>]

Erik,

Several folks have asked us how NOID would work with respect
to "hosts" that appear to be a single entity yet are 
implemented using load-balancers and multiple actual servers.

In this case, what does an "identifier" bind to?  

Noel is trying to make a semantic distinction between an
identifier that might be bound to one particular server in
the group and a different identifier that would be bound to
the entire "entity" of a balancer and servers supporting
a particular address.

While I think that this is an interesting and useful distinction,
I also think that we have bigger fish to fry at the moment.

Tony

|  Two points
|  
|  The folks in this WG seems to have gravitated to using
|  the term "identifier" to mean the name of a host (or stack).
|  I sometimes use the term "IP identifier" to make it clear 
|  where in the
|  stack it is relevant.
|  I don't know if it makes sense to use some other term at 
|  this point in time;
|  we do need to know what we mean and write it down.
|  
|  I don't know if there is any utility to NF-identifiers.
|  All uses of identifiers I can think of at least need some way to
|  verify to whom the identifier has been assigned. That might 
|  be because I'm
|  thinking about what you call names of objects and not pure 
|  identifiers.
|  Thus knowing where an NF-identifier would be useful would 
|  help clarify
|  things in my head.
