This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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 RTCDataChannel
s 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;
