RTCPeerConnection: sctp property
Baseline 2023
Newly available
Since May 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The sctp
read-only property of 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.
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
js
const peerConnection = new RTCPeerConnection();
const channel = peerConnection.createDataChannel("Mydata");
channel.onopen = (event) => {
channel.send("sending a message");
};
channel.onmessage = (event) => {
console.log(event.data);
};
// Determine the largest message size that can be sent
const sctp = peerConnection.sctp;
const maxMessageSize = sctp.maxMessageSize;
