Comcast
Simulating bad network connections so you can build better systems
Testing distributed systems under hard failures like network partitions and instance termination is critical, but it's also important we test them under less catastrophic conditions because this is what they most often experience. Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets. It works by wrapping up some system tools in a portable(ish) way. On BSD-derived systems such as OSX, we use tools like... -

Network Analyzer
Analyze the network carateristics like Delay, Jitter, Packet loss etc.
This software is a very simple network analyzer. When you click the start button, it will send a configurable stream of UDP packets to a host. (The receiving host is then required to echo all the packets back to the sender, which can be easily done via iptables rule under linux). Once the eched packets arrives back to the sender, the analyzer will calculate all the related statistics like, packet loss, jitter throughput etc... NOTE: in order to receive the echo packets you must... -

ServerArk
Linux game server UDP flood analyzer and protector
...Flood attacks on gaming servers are typically designed to make the players on the server lag to the point where the game is not playable. It can even crash some game servers. ServerArk automatically detects when a UDP flood attack occurs and uses kernel-level iptables rules to dynamically block those packets from being processed by the game server at all. It essentially lifts the game server "above the flood" and allows the game to still be playable, even under very heavy attacks. It can be run interactively with a high level of verbosity (to watch its logic in action), or it can be run unobtrusively as a daemon with output to daily log files (typical usage). -
