Get practical advice on managing IT infrastructure from up-and-coming industry voices and well-known tech leaders. Set the IP address or hostname of the device where you want to send random traffic. Set packet size and percent of circuit bandwidth to load randomly generated data on your wide area network WAN. Enhance network throughput by understanding how traffic thresholds enable proper load balancing.
When network engineers and admins want to analyze and improve network traffic performance, an important assessment they need to make is to determine how much load the network can take. WAN Killer software is built to be a random traffic generator that sends network traffic to the IP address and desired hostname. After launch, you can begin to adjust the packet size and the percentage of bandwidth you want to load with randomly generated data.

Web Performance Monitor Web application performance monitoring from inside the firewall.You can send different types of packets in succession using scripting.
The network interface you use to send packets must be compatible with WinPcap. Best results are usually obtained from a wired ethernet interface or a This tool does not send packets at a rate necessary to stress or otherwise saturate an interface. It is not a high speed Traffic Generator and it does not respond to packets coming back. Please consider the Packet Flooder Tool. Full header control for predefined packet types. You can specify most parameters in the header such as source and destination IPv4 address, packet length, packet types, flags and checksums.
The ethernet source and destination address can also be defined. Data Payloads can be added for certain types of packets. The payload can be simple text or a file of your choosing. The length of the data payload is limited by the interface MTU and the packet type.
We provide a Hex Editor to assist in creating or editing binary packet payloads or creating RAW packets. RAW Packet mode gives you full control. RAW packet mode simply means that you define the packet from ethernet header to the end using our Hex Editor or another editor. Then you send the packet.Ostinato Traffic generator tool Tutorial
The length of the raw packet is limited by the interface MTU. Playback previously saved. The packet size is limited to the MTU of your networktypically bytes for ethernet. Simple scripting is provided so that you can send different types packets. Scripted packet transmission can be used to send packets with parameters changing according to your script. Virtual machine ethernet interfaces.
Just be sure to set the VM network interface to bridged mode so that it goes directly to your host physical ethernet interface without going through the VM NAT interface. What this tool does not do This tool is NOT a traffic generator or packet flooding tool capable of stressing a network interface - if you need to send lots of UDP packets, use our Packet Flooder tool.
Burst rate of the Packet Generator tool is about 20Khz and this may vary from computer to computer.Multi-core support allows for even higher rates. It also features precise and accurate timestamping and rate control. Missing coverage for autogen. Package xdp allows one to use XDP sockets from the Go programming language. NET Assemblies built in.

Stress Testing a network or IT system with high volume of traffic will give us significant insights about the behavior of such systems in abnormal conditions such as DDoS attacks, sudden influx of traffic e.
Traffic packet generators are hardware or software tools that are concerned with the technical aspects of traffic and how it affects network and system resources. Since a big part of creating a positive user experience is your percentage of uptime and absence of slow response, packet loss, link overload etc, measuring how traffic spikes and fluctuations in user activity affect system performance and resources allocation is an important, and sometimes overlooked, function of IT operations.
A comprehensive testing system will include:. Performing stress tests and simulating traffic flows should be done both during network creation and on actual working networks once you go live.
This will help prevent problems like data loss and dropped connections. The list below includes both free and commercial options. What it does do is provide you with a packet generator that has a friendly GUI and a lot of power.
This free, open source tool is licensed under GNU GPLv3, and is supported by donations of cash, code, or other types of positive contributions. It is part of the well-known Nmap tool which is used mainly for network mapping and discovery in security assessments. These are also essential to providing a high degree of user satisfaction.
Use this tool to send normal ICMP ping packets for active hosts discovery as well as to send raw network packets for stress testing, detecting packet corruption, and exposing a range of attack weaknesses in your network.
As such, you can look for TRex for stateful and stateless DPDK-powered traffic generation that allows smart replay of actual traffic templates.
It allows analysis of multiple streams, and provides individualized, per-stream jitter, latency, and statistics reporting. This tool can also be used for stateful benchmark and stress testing load balancers, ISPs, DPI, NAT, and firewall protection as well as stateless traffic stream generation.
SolarWinds is a trusted company that puts a range of testing, management and monitoring tools at your disposal. Their WAN Killer tool performs proactive network stress and load testing by sending fully-customizable real traffic to specific host or IP address. This tool is not available for free, but there is a day free trial version with full functionality before you have to purchase a license.
Features of WAN Killer include:. This multi-purpose app allows you to send and receive simulated UDP, TCP, and SSL packets, configure and select ports, and run client and server software simultaneously. It also offers a great deal of flexibility and customization for methodology and input through command line or GUI. Best of all, this tool is completely free and open source. Not only does this easy app test incoming traffic, it also performs stress and load testing right over your network.
This tool has one purpose: to flood your network with UDP packets as fast as possible to see how much it can take. This is very useful to test how your network and security defences will behave during a volumetric DDoS attack for example. This app does allow you to set testing parameters, including target port, payload, and send rates. This tool was created for generating and analyzing Ethernet traffic and networks. The latest generation of this tool, 2. Packeth supports a wide range of protocols, including ethernet II, ethernet Free and open source and best suited for LAN environments.
This traffic generation tool gets back to basics with its second gen release. It measures both TCP and UDP performance under a range of traffic conditions with the goal of maintaining active iperf coding and preserving that coding which is inoperable. Iperf 2 also adds Python code control to enable centralized testing, and it releases timing-related statistics that include recording end-to-end latency. One thing it has over other network traffic generators is datagrams transmission, which is necessary for testing applications such as Open vSwitch.You seem to have CSS turned off.
Please don't fill out this field. Finally a packet replay and editing tool that simply works on all major platforms and command line can be used in scripts. Perfect for testing during development and validation phase.
I was looking for a packet replay tool, continuous looping multicast data feeds for debugging and testing radar data feed quality monitoring tools. Great work guys! Bittwist is great for crafting custom packets to test the Next Generation Firewalls my company is busy devleping. Thanks for the hard work. Please provide the ad click URL, if possible:.
