Hi Robin,
I very much agree with You and I find surprising the recommendation from
Eliot to give up work on it.
IMHO we should not dismiss it. LISP-NERD is very much alike other
approaches where we store all the mappings in ITRs/ETRs/APRs depending
where we place such ITR/ETR/APR nodes.
Sure perhaps requiring every CE to store all mappings is a stretch, but
we are told from every side that control plane memory is cheap. In fact
the scaling numbers presented by NERD were quite promising.
Thx,
R.
Hi Eliot,
Thanks for LISP-NERD.
While there are good reasons for having an architecture in which
every ITR does not need a full copy of the mapping information, I
think NERD is notable for the simplicity of its architecture and
directness of its operation: every ITR already knows the mapping, so
there is no fussing around with looking up the mapping from a nearby
or distant server.
