6.5 Throughput Testing
Overview:
The Throughput application performs the following measurements: Throughput performance, Frame Loss analysis, Delay analysis, Frame/Packet arrival analysis, received
Traffic Type analysis, and received Traffic Frame Size analysis. On the transmit side, the Throughput application currently allows only one stream with its MAC and IP
address, VLAN tags (up to 3), bandwidth/rate, frame size, and L2 and/or L3 quality of service (QoS) parameters. On the receiver end the traffic is analyzed on a per stream
basis as well as a global or aggregate measurement.
This application is very useful in verifying the transport of traffic with different prioritization settings across a network link. The test helps verify that the network can handle
high priority traffic and low priority traffic accordingly.
6.5.1 Setup
Unless otherwise noted, the Frame Header and related setups are the same as the ones described in section
. The following parameters must
be configured prior to performing a Throughput test:
Number of streams (See
General Settings
below)
Bandwidth per stream (See
General Settings
below)
Test layer
Frame Type
VLAN tag(s)
MPLS tag(s)
Frame header per stream (if applicable)
Traffic profile per stream (if applicable)
Error injection per stream (if applicable)
Control settings of the far-end device(s) (if applicable)
6.5.1.1 General Throughput Settings (Global Configuration)
# of Streams:
Up to 10 streams are available.
Stream #:
Allocated Bandwidth per Stream: The total bandwidth for all streams cannot exceed 100%.
Total (%):
Sum of all stream rates in %.
RTD Measurement:
Enable/disable the round trip delay measurement. It should only be enabled when running the test to a remote loopback.
Throughput General Setup
Multiple Streams
All streams are configured for the same test layer - if Layer 2 is selected, all streams will be Layer
2 traffic.
