A good example is the handling of packets which arrive at a LISP device which
does not yet have an identity->location mapping for the destination; such
packets are currently discarded. If this proves to have a significant
performance impact (predictive opinions differ), it is easy to change this so
that such packets are buffered, waiting for a mapping to be returned. The
LISP team in fact has a moderately lengthy list of such items (roughly a
dozen), but since they are not significant they are not covered here.
Easy to change to buffer instead of discard? How, exactly?
High-speed routers do not do buffering in similar scenarios even
though required by specs today (example: buffering packets waiting for
ARP resolution). Is there any indication that it would be feasible to
do later? How deep such a buffer could be?
