model: New content store variations: support for content freshness
The following content store realizations now fully support freshness set
in ContentObjects:
- ns3::ndn::cs::Freshness::Lru
- ns3::ndn::cs::Freshness::Random
- ns3::ndn::cs::Freshness::Fifo
Example ndn-simple-with-content-freshness demonstrates basics of new
content stores.
