GENEM-X is a feature-rich synthetic Ethernet & IP traffic generator, capture, playback and impairment application that runs on the PROVA-X test appliance. GENEM-X allows network equipment manufacturers and communications service providers to stress-test networking devices, infrastructure or Virtual Network Functions (VNFs) in a lab or production environment. GENEM-X can emulate 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 you to add delay, jitter and loss to flows to emulate complex networks and track application performance. GENEM-X transforms the PROVA-X into the ultimate multi-tool test appliance.
