Features

Multiple use cases

• Functional testing of network devices, circuits and networks
• Verification of network QOS
• Network performance and load testing - line rate 10G, 40G and 100G with the Turbo add-on

Test Topologies

• Create customized test topologies

Graphical UI

• User friendly GUI for manual testing and verification

Many Protocols

• Support for the most common standard protocols
  • Ethernet/802.3/LLC SNAP
  • Unicast, multicast, broadcast traffic
  • VLAN (with QinQ)
  • ARP, IPv4, IPv6, IP-in-IP a.k.a IP Tunnelling (6over4, 4over6, 4over4, 6over6)
  • TCP (stateless), UDP, ICMPv4, ICMPv6, IGMP, MLD
  • Any text based protocol - HTTP, SIP, RTSP, NNTP etc. (underlying transport will be stateless however)
  • More protocols in the works …
• User defined script to substitute for an unimplemented protocol (Example)

Pcap Import, Edit and Replay

• Import and edit PCAP files, replay and save back

Extensive packet crafting

• Create packets from scratch - specify protocols and protocol fields to match your requirements
• Set a value for any field of any protocol
• TOS/DSCP setting for QOS validation
• Stack protocols in any arbitrary order to test error cases (📖 Doc)
• User provided Hex Dump - specify some or all bytes in a packet

Flexible traffic streams

• Create and configure multiple streams
• Configure stream rates, bursts, no. of packets
• IMIX traffic profile
• Multiple flows using variable packet fields across packets at run time e.g. changing IP/MAC addresses or UDP ports (📖 Doc)

Interface and Stream Statistics

• Extensive interface level receive/transmit/error statistics and rates for realtime network monitoring and measurement
• Per stream statistics for accurate and granular packet loss, latency and jitter measurement

Device and Protocol Emulation

• Network Device Emulation (ARP and ICMP) for multiple IPv4/IPv6 hosts to aid in network traffic simulation (📺  Video Tutorial and Demo)
• Protocol Emulation (DHCP, IGMP, OSPF, BGP)

Single pane of glass

• Configure and control multiple traffic generating agents from a single controller

Multi-user support

• Multiple users can share ports on the same host (📖 Doc)

Automation API

• Fully featured Python API for scripting and automation - anything you can do via the GUI, you can do via the API (the GUI is built on top of the API)

Convenience

• Capture and view traffic from within the app (needs Wireshark)
• Exclusive control of a port to prevent the OS from sending stray packets provides a controlled testing environment (Windows only)

Deployment options

• Cross-Platform - runs on Windows, Linux, Mac OS X
• Also available as Virtual Appliance, Docker containers
• Drop in integrations for GNS3, EVE-NG, CML and Containerlab

Not supported

• 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
