Sequence Error Detection

The complexity of modern Ethernet and IP networks is constantly increasing as new technologies and applications are implemented. As data traverses an Ethernet network, the communication stream can be affected by various anomalies, which degrades performance.

Xena Networks Layer 2-3 testers – the XenaBay and XenaCompact equipped with the relevant test modules – are used to verify the performance of networks and network devices. This is done by sending packets on Ethernet links running up to 100 Gbps and checking the packets when they return to the tester. The testers will detect anomalies in the sequence of the received packets and report the anomalies to the user. This Application Note explains how the detection works and how this is shown in the test results.
