Description

The NDN seminar on 20160224 used NdnCon on the NDN testbed.

During the conference, two producers peter and confbridge are connected to REMAP gateway router, their prefixes are setup with nfd-autoreg, and the namespace has AccessStrategy.

After the conference ends, on REMAP gateway router, nfd-status -v shows that the PIT contains 52185 entries, and the NameTree contains 96278 entries, despite that there's very low traffic volume; these counters stay at high levels even after several hours.

This situation is not observed on other testbed gateway routers, where there are at most one producer relying on nfd-autoreg.
