On the packet specification section of the website (here:
http://named-data.net/doc/ndn-tlv/interest.html#mustbefresh), there is
written:
The FreshnessPeriod carried in each Data packet (Data Section) is set
by the original producer. It starts counting down when the Data packet
arrives at a node. Consequently if a node is N hops away from the
original producer, it may not consider the Data stale until N X
FreshnessPeriod after the Data is produced.
Then, I do not completely agree with the last sentence. I would write
[...] it may not consider the Data stale until N x T after the Data
is produced, where T is the average time requested to send the
requested Data packet between two nodes on the path producer-consumer.
What do you think about it?
