So to answer your statement, based on these results, I think NERD
does a
better job at minimizing the delay to obtaining a mapping. But I don't
know if it would scale to a global mapping system so that is why I
suggested it could be used for inter AS traffic engineering (the
second
level of LISP, that makes use of private mapping database between the
AS-es).
So I am wondering what people think. Is there a hybrid that we can use?
That is, for NERD it is all or nothing. But a typical ITR needs some
but not all mappings.
How about this:
(1) Have an ITR, when it boots up, ask its map-resolver for all
mappings it might have cached.
(2) It may not eliminate all Map-Requests but maybe a large number of
them.
(3) Does require the map-resolver to be a caching system.
Comments?
