Hi Tai-Lin

In NDN architecture, a pending Interest table entry will be erased after
first satisifying Data.
Data from other nexthops, if any, will be treated as unsolicited and

In NFD, the "Interest table" is a superset of "pending Interest table": an
Interest table entry is either a pending Interest or a recently satisfied
An Interest table entry is kept until "straggler timer" expires. This
allows the strategy to collect measurements about other possible nexthops.
See NFD Developer Guide, Forwarding section for details.

Yours, Junxiao
