Ostinato

It is an L2/L3 Ethernet/IP packet generator and network traffic tester that generates, customizes and replays traffic to validate throughput, QoS, multicast, routing, switching and device behavior under load. It is for network engineers, developers, IT and operations teams in labs, QA, vendors, education and research across businesses of all sizes. It runs on standard COTS hardware, laptops, VMs and containers without special hardware, with a GUI and Python API, as an alternative to expensive shared hardware generators.
