Detailed Description

The neighbor database contains collected information about neighbors. This includes the last timestamp on which a neighbor was seen, the bundles this neighbors has received (bloomfilter with age).

NeighborDatabase::NeighborEntry & dtn::routing::NeighborDatabase::create

(

const dtn::data::EID &

eid

)

Query a neighbor entry of the database. If the entry does not exists, a new entry is created and returned.

Parameters:

eid	The EID of the neighbor.

Returns:

The neighbor entry reference.
