libdatachannel - client-benchmark

This directory contains a native client to open Data Channels with WebSocket signaling using libdatachannel and benchmark functionalities. It offers three functionalities;

  • Benchmark: Bi-directional data transfer benchmark (Also supports One-Way testing)
  • Constant Throughput Set: Send desired amount of data per second
  • Multiple Data Channel: Create desired amount of data channel

Start Signaling Server

  • Start one of the signaling server from the examples folder. For example start signaling-server-nodejs like;
    • cd examples/signaling-server-nodejs/
    • npm i
    • npm run start

Start client-benchmark Applications

Start 2 applications by using example calls below. Then copy one of the client's ID and paste to the other peer's screen to start offering process.

Usage Examples

Benchmark for 300 seconds

./client-benchmark -d 300

Example Output (Offering Peer's Output);
