Nokia Nokia Nokia This document specifies how the Binary Floor Control Protocol (BFCP) can be instantiated as a data channel sub-protocol, using the SDP offer/answer exchange-based external negotiation defined in [I- D.ietf-mmusic-data-channel-sdpneg]. Two network configurations are documented: a WebRTC end-to-end configuration (connecting two BFCP over data channel endpoints), and a gateway configuration (connecting an BFCP over data channel endpoint with an BFCP over (TLS)/TCP/IP (or over (DTLS)/UDP/IP) endpoint).
