DSCP

[Daniel Kristiansen]

Trying to get QoS working with our implementation of webrtc using Chrome.

We have a node.js signal server and all traffic remains on our WAN. However, we wanted to make sure that we're able to use QoS to ensure video/audio quality.

I tested out adding 'dscp=true' to the apprtc demo page and it doesn't appear to change the DSCP tagging on the traffic at all. I've attempted to add the following constraints when I make my peerConnections: 

rtc.dataChannelConfig = {

    "optional": [{

      "RtpDataChannels": true

    }, {

      "DtlsSrtpKeyAgreement": true

    }]

  };

changed to:

rtc.dataChannelConfig = {

    "optional": [{

      "RtpDataChannels": true

    }, {

      "DtlsSrtpKeyAgreement": true

    }, {

"googDscp": true

}]

  };

This doesn't appear to cause the packets to be tagged either. 

Thanks!

Thanks, yes it seems like DSCP currently works for Mac/Linux but not for windows. I started a thread in issue 277022.
