Revision 1068654 of RTCSctpTransport

<p>{{APIRef("WebRTC")}}{{SeeCompatTable}}</p>

<p>The <strong><code>RTCSctpTransport</code></strong> interface provides information which describes a Stream Control Transmission Protocol (<strong>{{Glossary("SCTP")}}</strong>) transport. This provides information about limitations of the transport, but also provides a way to access the underlying Datagram Transport Layer Security (<strong>{{Glossary("DTLS")}}</strong>) transport over which SCTP packets for all of an {{domxref("RTCPeerConnection")}}'s data channels are sent and received.</p>

<p>You don't create {{domxref("RTCSctpTransport")}} objects yourself; instead, you get access to the <code>RTCSctpTransport</code> for a given <code>RTCPeerConnection</code> through its <strong>{{domxref("RTCPeerConnection.sctp", "sctp")}}</strong> property.</p>

<p>Possibly the most useful property on this interface is its {{domxref("RTCSctpTransport.maxMessageSize", "maxMessageSize")}} property, which you can use to determine the upper limit on the size of messages you can send over a data channel on the peer connection.</p>
