Hi Kourtney,

Currently, NFD/ndnSIM implementation doesn't restrict anything for the long-lived interests.  Interests will be in PIT for the time equal or larger than specified in InterestLifetime of the interests (it can be larger if there are multiple interests for the same data, which will extend lifetime of the PIT entry).
