[ndnSIM] NLSR and ndnSIM?

Dear all,


within our research we noticed that the "best-route" forwarding strategy of
NFD differs significantly from ndnSIM 1.0. For instance, when a link failure
or congestion occurs, the forwarder will not learn anything about the
underlying issue. The client will re-issue after the interests times out
(depending on the interest timeout, this could be rather long), and the
forwarder will try the very same outgoing face again (which is probably
still congested).

With ndnSIM 1.0, the notion of "red, green, yellow faces" in combination
with NACKs was working very well. I understand that the idea for NFD is to
use NLSR, though I haven't seen NLSR active/working in ndnSIM yet. Is there
ongoing work, are there any examples available?


Best regards,
