Ostinato

Do you want to test the performance of your network devices, protocols, or topologies? Ostinato offers a friendly GUI (Graphical User Interface) to reproduce unexpected behavior, network problems, or outage issues with real test traffic. It is a cross-platform tool that allows network engineers to create complex traffic scenarios and craft packets with various protocols. You can verify your network behavior or configure any fields of the selected protocol for any connected network.

Ostinato offers a Python API to automate network tasks. Using its interface, you can create traffic streams and get detailed statistics for ports and streams, including transmitted and received packets, loss, latency and jitter. It is well-designed and covers a range of functionalities, making it a popular traffic generator software. It supports the most common standard protocols and can modify any field, such as IP and MAC addresses. You can also add new protocols through scripting, capture packets, and view them in Wireshark.

Features:

• A popular tool used to generate network traffic, with the possibility to control the rate, bursts and timing of every stream.
• It offers an intuitive graphical interface to validate configurations like QoS, multicast, routing, and load balancing across labs.
• You can generate a stream of network packets, configure any fields of the protocol, and transmit the streams over other connected networks.
• It has multiple use cases and allows functional testing of network devices, circuits, and networks. You can also create customized test topologies.
• It supports the most common standard protocols, including Ethernet, VLAN, QinQ, ARP, IPv4, IPv6, ICMP, UDP, TCP, GRE, MPLS, VXLAN, or any text-based protocol such as HTTP, SIP, RTSP, NNTP, etc.
• The software can replay PCAP files to reproduce real-world traffic; on Windows it is installed with a setup program and requires the Npcap driver.

Ostinato lets network teams generate controlled L2/L3 test traffic to validate, test and troubleshoot networks and network devices.

Ostinato is designed so that an average user can also access it and test the performance of a network. It specifies protocols to match your requirements and can create multiple streams simultaneously. It uses a controller-agent architecture, so a single GUI can configure multiple ports on multiple computers that run the Drone agent. Ostinato is sold as a subscription with Solo, Pro and Business plans, and a trial can be requested.
