This playground contains testing tools for WebRTC Data Channels. Some are useful for measurements, some are demos and some may not work.
Netperfmeter is a performance measurement tool for the WebRTC Data Channels. It simultaneously transmits unidirectional data via Data Channels to a peer and measures the resulting bandwidth for each Data Channel.
Each Data Channel can be configured separately.
This tool is port of Thomas Dreibholz's Netperfmeter.
Browsertests checks the implementation of WebRTC Data Channels via a collection of tests according to the W3C Specification.
Stresstest to create multiple local Peer-Connections containing multiple Data Channels which are sending messages.
The two peers exchange the values of their gyro sensors. A local peer changes its background color (R,G,B) in relation to the peers sensor values.
Speedtest - runtime and message size are configurable.
You can trace and analyze WebRTC by using Wireshark.
Get Wireshark with text2pcap (included by default).
Set environment variables
NSPR_LOG_MODULES to SCTP:5,DataChannel:5
NSPR_LOG_FILE to /Users/username/logfile << change path
A tutorial for setting variables on different platforms is here.
Start Chrome with additional parameters: --enable-logging --v=4
Chrome will log file. For example chrome_debug.log
grep SCTP_PACKET logfile > sctp.log
text2pcap -n -l 248 -D -t '%H:%M:%S.' sctp.log sctp.pcapng
Open sctp.pcapng in Wireshark.
#!/bin/sh
SCRIPT=$(readlink -f "$0")
SCRIPTPATH=$(dirname "$SCRIPT")
echo $SCRIPTPATH
export NSPR_LOG_MODULES=SCTP:5,DataChannel:5
export NSPR_LOG_FILE=$SCRIPTPATH/firefoxlog
/Applications/Firefox.app/Contents/MacOS/firefox-bin
grep SCTP_PACKET firefoxlog.child-1 > sctp.log
text2pcap -n -l 248 -D -t '%H:%M:%S.' sctp.log sctp.pcapng
To start a WebRTC compatible turn server:
turnserver -L <listening-ip-addr> -a -v -n -r realm -u user:password -p <port>
We like feedback! :) Feel free to report bugs or ideas to us!
