The WebRTC API's RTCIceComponent enumerated type contains DOMString values that each identify a specific ICE component; these are "rtp" and "rtcp". These strings are mapped to corresponding numeric values as they appear in the candidate a-line in SDP.


Identifies an ICE transport which is being used for the Real-time Transport Protocol (RTP), or for RTP multiplexed with the RTP Control Protocol (RTCP). RTP is defined in RFC 3550. An RTCIceComponent of this value corresponds to the component ID field in the candidate a-line with the value 1.
Identifies an ICE transport being used for RTCP, which is defined in RFC 3550, section 6. This value of RTCIceComponent corresponds to the component ID 2.

Usage notes

The RTCIceComponent type is used by the component property of RTCIceCandidate and RTCIceTransport objects.
