Hi, >> *Q4 (CLARIFICATION):* >> The text says: >> "An 'm' line that specifies 'SCTP' or 'SCTP/DTLS' or 'DTLS/SCTP' MUST >> further qualify the application-layer protocol using an fmt >> identifier." >> I do understand what you are trying to say, but I think the "qualify" >> word is a little confusing. >> Maybe something like: >> "An 'm' line that specifies 'SCTP' or 'SCTP/DTLS' or 'DTLS/SCTP' MUST >> further include an fmt value that identifies the application-layer >> protocol >> carried on top of the SCTP association." > > The clarification would be fine, but both the original and the clarification are misleading. The fmt value does not identify an application-layer protocol - it identifies a port number. This is explained later in section 4.1. Correct. The SDP sctpmap attribute then associates that port number with an SCTP application. Regards, Christer
