Test Description
Frame Loss Measures the number of frames lost from flows and
groups sent through a device.
Jumbo Measures frame loss, latency, and latency distribution
in flows and groups of flows sent through a device, and
updates each of these results simultaneously. It also
measures latency standard deviation based on latency
distribution, and the number of frames received that
were out of sequence.
Throughput Measures the maximum rate at which frames from
flows and groups sent through a device can be sent
without frame loss.
Latency Measures the minimum, maximum, and average
latency of received frames in flows and groups of flows
sent through a device. Latency is calculated for all
received frames.
Latency Distribution Measures the latency of received frames in flows and
groups of flows sent through a device, and sorts them
into eight latency buckets. Compared to the Latency
test, this test can provide a finer view of latency
behavior at the DUT’s load tolerance limits.
Latency Snap Shot Measures the latency of each received frame, for a
specified number of frames in flows and groups of
flows sent through a device.
