DESCRIPTION
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 ipfw and pfctl to inject failure. On Linux, we use iptables and tc. Comcast is merely a thin wrapper around these controls. Windows support may be possible with wipfw or even the native network stack, but this has not yet been implemented in Comcast and may be at a later date. On Linux, Comcast supports several options: device, latency, target/default bandwidth, packet loss, protocol, and port number.
Features
- To shape traffic in BSD-derived systems, create an ipfw pipe and configure it
- You can control incoming and outgoing traffic separately for any specific host or network
- Comcast will determine the system commands to execute, log them to stdout, and execute them
- The default bandwidth specified will apply to all egress traffic
- Comcast supports several options like device, latency, target/default bandwidth, etc.
- Designed to simulate common network problems like latency, bandwidth restrictions, etc.
