Ostinato

Ostinato is a packet crafter, pcap player, and traffic generator designed for testing and validating network configurations. According to the vendor, this tool caters to businesses of all sizes, providing the flexibility and capabilities needed to create, modify, and generate network traffic for various protocols.

Key Features

Packet Crafting and Sending: Ostinato allows users to craft and send packets of various protocols, including Ethernet/802.3/LLC SNAP, unicast, multicast, and broadcast traffic. Users have the flexibility to change any packet field of any protocol to any value, enabling customization of packet configurations.

Packet Editing and Replay: Users can import and edit PCAP files, replay them, and save them back. Ostinato offers extensive packet crafting capabilities, allowing users to create packets from scratch by specifying protocols and protocol fields to match their requirements. Users can set values for any field of any protocol and vary packet fields across packets at runtime.

Flexible Traffic Streams: Ostinato enables users to create and configure multiple traffic streams. Users can easily configure stream rates, bursts, and the number of packets for each stream. The tool supports IMIX (Internet Mix) traffic, allowing users to simulate a mixture of different traffic types.

Interface and Stream Statistics: Ostinato provides extensive interface-level receive/transmit/error statistics and rates, enabling real-time network monitoring and measurement. Users can also access per-stream statistics for accurate and granular packet loss measurement.

Device Emulation: Ostinato offers network device emulation for multiple IPv4/IPv6 hosts, aiding in network traffic simulation. This feature includes ARP and ICMP emulation, allowing users to simulate multiple hosts and their interactions.

Multi-User Support: Ostinato supports multiple users sharing ports on the same host, facilitating collaboration and resource sharing.

Automation API: Ostinato provides a fully-featured Python API for scripting and automation. Users can automate any task that can be performed via the GUI, as the GUI itself is built on top of the API.

Convenience: Ostinato allows users to capture and view traffic from within the application using Wireshark. The tool also offers exclusive control of a port to prevent the operating system from sending stray packets, providing a controlled testing environment (Windows only).

Deployment Options: Ostinato is cross-platform and runs on Windows, Linux, Mac OS X, and Raspberry Pi. It is also available as a Live CD/USB and Virtual Appliance.
