The Y.1731 frame transmission for a service attached to an iterator continues endlessly
unless intervened and stopped by an operator or until the iteration-count condition is
met. To stop the iterator from sending out any more proactive SLA measurement frames,
the operator must perform one of the following tasks:
Enable the deactivate sla-iterator-profile

an Iterator Profile.
In two-way delay measurement, the delay measurement message (DMM) frame is
triggered through an iterator application. The DMM frame carries an iterator type, length,
and value (TLV) in addition to the fields described in standard frame format and the
server copies the iterator TLV from the DMM frame to the delay measurement reply
(DMR) frame.
In one-way delay variation computation using the two-way delay measurement method,
the delay variation computation is based on the timestamps that are present in the DMR
frame (and not the 1DM frame). Therefore, there is no need for client-side and server-side
clocks to be in sync. Assuming that the difference in their clocks remains constant, the
one-way delay variation results are expected to be fairly accurate. This method also
eliminates the need to send separate 1DM frames just for the one-way delay variation
measurement purpose.
In proactive mode for loss measurement, the router sends packets in standard format
along with loss measurement TLV and iterator TLV.
