I am looking at https://github.com/named-data/jndn/commit/f0a50c635afe0cbd27cc84e188b582eb7e457b9b#diff-e12e36065baf92aa80b384cbfb3eef02R35 and was interested in finding out the different actions others are taking: obviously log in all cases, wait and re-send for congestion, fail and throw for no route, ___ for duplicate?

For the application these are probably basic actions.  For routers that have multiple interfaces, you may want to do immediate actions (i.e., send to an alternative face) instead of waiting.

App should never get any duplicate NACKs.  If it is getting them, then there is some serious problem somewhere.
