Introduction

Ostinato is a packet generator and network traffic generator with a friendly GUI. Also a powerful Python API for network test automation. Craft and send packets of several streams with different protocols at different rates. Think of it as “Wireshark in Reverse”.

Ostinato aims to provide a traffic generator and network testing tool for every network engineer and developer - something not possible today with existing commercial network test equipment. With the right tool, network developers and engineers can do their jobs better and improve the quality of networking products.

What Ostinato cannot do

  • Ostinato is stateless - stateful connection-oriented TCP connections are not supported. Please try TRex or Warp17 instead.
  • Ostinato cannot be used for generating fake traffic to websites
