Appendix: <strong>10</strong>GE<br />
<strong>Testing</strong> Examples<br />
The test plans presented in this section<br />
include several examples demonstrating<br />
how <strong>Ixia</strong>'s solution addresses the<br />
challenges of <strong>10</strong>GE switch testing.<br />
1. Throughput <strong>Testing</strong>: RFC 2544 Throughput<br />
Test<br />
Objective. To characterize the <strong>10</strong>GE switch<br />
data plane performance in forwarding<br />
traffic. IETF RFC 2544 defines a test<br />
methodology for this characterization,<br />
divided into the following three tests:<br />
• The back-to-back test determines how<br />
the DUT responds to different<br />
quantities of frames with the minimum<br />
Figure 4. RFC 2544: Throughput Test — setup.<br />
gap allowed by the protocol<br />
specification.<br />
• The frame loss test determines how<br />
the DUT responds to streams with<br />
different loading.<br />
• The throughput test finds the highest<br />
rate at which the DUT can forward<br />
frames.<br />
Setup. A minimum of two <strong>10</strong>GE test ports is<br />
required for this test. <strong>Ixia</strong>'s IxScriptmate<br />
application can be used to run RFC 2544<br />
tests.<br />
Parameters. Select the test port pairs,<br />
frame size mode and frame sizes, and<br />
number of iterations.<br />
