GENEM-X is a 10G Ethernet/IP test application that provides a stress-test for networking devices, infrastructure or Virtual Network Functions (VNFs) in a lab or production environment. GENEM-X emulates network traffic by generating packets up to line-rate on each of the PROVA-X test interfaces while simultaneously filtering and capturing flows for analysis. It can be used for Service Assurance in production environments, on-demand troubleshooting and SLA reporting. The network emulation features allow the addition of delay, jitter and loss to flows to emulate complex networks and track application performance. GENEM-X offers a set of tools to test RFC 2544, Y.1564, 7.1731, network diagnostics, network traffic generator and WAN emulation.
