PyNetSim targets the generation of background traffic and anomaly generation for testing anomaly detection algorithms. It is written basically without simulation in terms of computer science, but it uses parts of simulation theory. Therefore, it is a generator of such traffic types. It deploys its full power when running on many virtual machines.
Multiple Devices Proxy is an application proxy to communicate with pipes, serial ports (RS-232/RS-485), TCP/IP, and potentially all devices in a host computer via TCP/IP sockets. It supports multicast and communication isolation. Any server may have many resources, e.g. 2 pipes, 4 RS-232, and 2 connected sockets to another server. Clients may ask for 1 to many of these resources, and all data will be multicast.
curl-loader is a powerful tool for testing and generating load for Web applications. It uses HTTP, FTP, and TLS/SSL stacks. The loader simulates tens and hundreds of thousands of users or clients, each optionally with its own IP address. The goal is to provide an alternative to the Spirent Avalanche and Ixia IxLoad Web application testing solutions.
simena-io is a Linux tool written in Perl and designed to show ethernet interface statistics in bits/second and packets/second in real time. It requires at least Linux kernel 2.2 and Perl 5. It does not require a root account. There is only one command parameter: the refresh rate in seconds. If no parameter is provided, simena-io will refresh every 2 seconds by default. Detailed documentation can be obtained by running "perldoc simena-io".
diversifEye is a scalable IPTV, Triple Play, and network emulation, analysis, and per flow traffic generation tool specialising in Quality of Service (QOS) and Quality of Experience(QOE) verification that can emulate the client and/or server side of these interactions. The GUI is supported on Windows, Linux, Solaris, and Mac OS X.
