[RRG] cache issues in LISP and CONS

[Dan Jen <jenster@CS.UCLA.EDU>]

The issue regarding packet drops with LISP and LISP-CONS has been
brought up a few times on the list.

Basically, packets are dropped for every ITR cache miss.  Since CONS
mapping requests may take a long time to be satisfied, this may result
in unacceptable service.

Suggestions have been made to route packets on the old topology in the
event of ITR cache misses. However, this leads to a major incremental
deployment issue -- since LISP adopters will still need to maintain
their routes in the old topology, there would be no reduction in the
size of the global routing table.  

I have not seen any other suggestions on how to handle this issue.
Could this be a fundamental problem with the design, or are there other
solutions? 

Thanks,

Dan
