Title: About detection of path failure

G'day.

About Path failure detection

According to SCTP specification (RFC2960), paths' status maintained by
HeartBeat mechanism.
But In case of the primary path, which means currently used to exchange data, HeartBeats
are not placed without explicit Heartbeat reqeust.
the primary path's status is just checked by real data exchanges and related retransmission
mechanism.
Is that right?

If yes, then If after association established, and there's no data exchange,
How to detect failure of the primary path?
Is the SCTP specification dealing with this? Is that just the matter of implementation?

Thanks In Advance.
