3.1.6.9 Presence Timer

  • Article

When this timer fires, it means that presence maintenance detected an incorrect number of presence records (with their Deleted flags unset) currently published in the graph.

If there is currently a presence record in the graph database with its Deleted flag unset and with the local node's node ID, and the number of presence records in the database is still higher than Max Presence Records + 10:

  • The local node MUST delete the presence record for its node ID, as specified in section 3.1.7.9.

If there is currently no presence record in the graph database with the local node's node ID and with its Deleted flag unset, and the number of presence records is still lower than Max Presence Records:

  • The local node MUST publish a presence record containing its node ID, as specified in section 3.1.7.4.
