Summary Results

³

Step: Available only for the Frame Loss subtest. This value indicates
the 10 % interval of throughput decreased. The subtest is repeated at
each decreased throughput. The subtest is stopped for a frame size
when there are 2 successive trials in which no frames are lost or when
the throughput has reached 0 % of the full media speed.

³

TX Frames: Available only for Throughput, Frame Loss and
Back-to-Back subtests. The count of transmitted frames for the
iteration in progress. This value is kept throughout the iteration until the
next iteration begins. When the next iteration begins, the value
displayed will momentarily be “0” while data is collected.

³

RX Frames: The count of received frames for the iteration in progress
after the test frames have been transmitted and a pause of 2 seconds
has passed. This value is kept throughout the iteration until the next
iteration begins. When the next iteration starts, the value displayed will
momentarily be “0” while data is collected.

Note: For DTS RFC 2544, the results for the

Local-to-Remote direction are
obtained between test iterations.

The possible subtest statuses that
reflect the test phase or results of the
currently tested frame size are listed as
follows:
