Ostinato

Purpose: Ostinato generates, customizes, or replays L2/L3 traffic to validate throughput, QoS, multicast, routing, switching, protocol behavior, and network performance.
Packet crafting: Users can edit supported protocol header fields, control frame size, and create custom headers with hexdumps or scripts.
PCAP replay: Ostinato can edit and replay PCAP files, preserve or modify packet timing, and loop or reorder packets.
Traffic analytics: It reports port and stream transmit/receive statistics, detects per-stream packet loss, and measures latency and jitter using software timestamps.
Protocol emulation: DHCP client/server, IGMP/MLD host, OSPFv2, and BGP emulation are marked Technical Preview.
Performance: The site states that the Turbo add-on supports line-rate traffic up to 400G.
Automation: Ostinato provides a Python API for building streams and test scenarios, controlling runs, collecting counters, and integrating tests with CI/CD pipelines.
Integrations: The maker lists GNS3, EVE-NG, Cisco CML, and Containerlab as supported lab environments, and says Ostinato works on AWS and Azure cloud VMs.
Security and privacy: The privacy policy says product telemetry is pseudonymous and excludes packet payloads, packet captures, license keys, hostnames, user-configured MAC/IP addresses, and other customer-specific network configuration data.
Support: Customers with Pro or Business licenses may submit support tickets; Pro email support is available for 30 days from purchase, and community forums are available to all listed license tiers.
License requirements: An active subscription is required to use the software, and license checks use the internet; Business supports offline license checks for Linux Drone agents in air-gapped environments.
Notable limits: Ostinato does not support stateful TCP connections, and the pricing comparison limits included PCAP import to 5,000 packets for Solo and 250,000 for Pro, with Business listed as unlimited.
