This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.
The read-only sctp property on the RTCPeerConnection interface returns an RTCSctpTransport describing the SCTP transport over which SCTP data is being sent and received. If SCTP hasn't been negotiated, this value is null.
The SCTP transport is used for transmitting and receiving data for any and all RTCDataChannels on the peer connection.
Syntax
var sctp = RTCPeerConnection.sctp;
Value
A RTCSctpTransport object describing the SCTP transport being used by the RTCPeerConnection for transmitting and receiving on its data channels, or null if SCTP negotiation hasn't happened.
Example
var pc = new RTCPeerConnection();
var channel = pc.createDataChannel("Mydata");
channel.onopen = function(event) {
channel.send('sending a message');
}
channel.onmessage = function(event) {
console.log(event.data);
}
// Determine the largest message size that can be sent
var sctp = pc.sctp;
var maxMessageSize = sctp.maxMessageSize;
