| Time Synchronization Describes how to synchronize the clocks of multiple Xena test chassis. | Download |
Hints and Guidance |
|
| Measuring Frame Delay Variation Describes how FDV is measured accurately and in real time with Xena Networks testers. | Download |
| Testing at 100% load with line rate speed compensation Illustrates how to compensate for small differences in line rates between the Xena tester and the DUT/NUT. | Download |
| Gauges - Meters A step-by-step guide to presenting Xena test results in gauges/meters, using Graphite and Grafana installed on a virtual Linux machine. | Download |
| Freely Programmable Test Packets This Application Note explains the Custom Data Field and Extended Payload features available in some of Xena high-speed test modules can be used to verify the behaviour of DUTs in multiple traffic scenarios. | Download |
| Sequence Error Detection Xena testers detect anomalies in the sequence of packets received after they have traversed the network, and report these anomalies to the user. This Application Note explains how this detection process works and how the results are displayed. | Download |
| Scheduling Modes The Xena Traffic Generator supports four ways (scheduling modes) of merging the streams into the test traffic that is sent from one physical port. This application note explains the four scheduling modes. | Download |
| PCAP Replay How to capture traffic into PCAP files and replay on Xena’s Vulcan traffic generation & analysis platform to reproduce your own reality for stateful performance verification. | Download |
| DHCP IP Assignment Don’t want to add a DHCP Server to a test environment? Here is some simple scripting that lets you use a Valkyrie traffic generator to function as a basic DHCP server. Note: To use this scripting, you need to download 2 text files in this zip folder. | Download |
