bailehang / clumsy

A fork of jagt/clumsy to add bandwidth limit

clumsy

clumsy makes your network condition on Windows significantly worse, but in a managed and interactive manner.

Leveraging the awesome WinDivert, clumsy stops living network packets and capture them, lag/drop/tamper/.. the packets on demand, then send them away. Whether you want to track down weird bugs related to broken network, or evaluate your application on poor connections, clumsy will come in handy:

• No installation.
• No need for proxy setup or code change in your application.
• System wide network capturing means it works on any application.
• Works even if you're offline (ie, connecting from localhost to localhost).
• Your application keeps running, while clumsy can start and stop anytime.
• Interactive control how bad the network can be, with enough visual feedback to tell you what's going on.

See this page for more info and build instructions.

This Fork

This is a fork of the original jagt/clumsy to add the bandwidth limit feature:

The algorithm is similar to webrtc, which uses a sliding window (size = 1 second) to statistic current bandwidth.
