   The Real-Time Communication in WEB-browsers (RTCWeb) working group is

   charged to provide protocols to support direct interactive rich

   communications using audio, video, and data between two peers' web-

   browsers.  For the support of data communication, the RTCWeb working

   group has in particular defined the concept of bi-directional data

   channels over SCTP, where each data channel might be used to

   transport other protocols, called sub-protocols.  Data channel setup

   can be done using either the in-band Data Channel Establishment

   Protocol (DCEP) or using some out-of-band non-DCEP protocol.  This

   document specifies how the SDP offer/answer exchange can be used to

   achieve such an out-of-band non-DCEP negotiation.  Even though data

   channels are designed for RTCWeb use initially they may be used by

   other protocols like, but not limited to, the CLUE protocol.  This

   document is intended to be used wherever data channels are used.
