Event Log
Throughput Testing (Multiple Streams)
Overview
The throughput application (or the multiple streams application) performs the following measurements: through-
put performance, frame loss analysis, delay analysis, frame/packet arrival analysis, received traffic type ana-
lysis, and received traffic frame size analysis. On the transmit side, the throughput application allows for the
configuration of up to 8 traffic streams with their own MAC and IP addresses, VLAN tags (up to 3 per stream),
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 (up to 8 streams) 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 net-
work link. The test helps verify that the network can handle high priority traffic and low priority traffic accord-
ingly.
Setup
Unless otherwise noted, Frame Header, Traffic, and Error Injection setups are identical to the ones described
in the
"BERT" on page 44 section. The following parameters must be configured prior to performing a Through-
put test:
l
Number of streams (See General Settings below)
l
Bandwidth per stream (See General Settings below)
