UDP/DTLS/BFCP is already defined in 4583bis, except we specified the tag as UDP/TLS/BFCP. I agree it can be used with and without ICE.

Cheers,

Only UDP/DTLS/BFCP and TCP/DTLS/BFCP can be used with ICE, with ICE not supported for all the other BFCP flavors.

Ok, so TCP/BFCP and TLS/BFCP will still be kept in 4583bis, and should be used when ICE is not used?


TCP/BFCP, TLS/BFCP and UDP/BFCP will be kept in 4583bis and can only be used when ICE is not used. UDP/DTLS/BFCP and TCP/DTLS/BFCP are two transport that can be used with or without ICE.
