This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
The read-only property RTCDataChannel.bufferedAmount returns an unsigned long containing the amount of bytes that have been queued for sending: that is the amount of data requested to be transmitted via RTCDataChannel.send() that has not been sent yet. Note that if the channel state, as given by RTCDataChannel.readyState is "closed", the buffering continues.
Syntax
var amount = dataChannel.bufferedAmount;
Example
var pc = new RTCPeerConnection();
var dc = pc.createDataChannel("my channel");
…
console.log("Channel amount: " + dc.bufferedAmount);
