This document discusses the issues involved in elevating RTP to the status of protocol, equivalent to TCP or UDP. This will result in all RTP packets being explicitly labeled as such in the packet header. This vastly simplifies the problem of classifying real time streams. Such classification operations are essential for successful deploy- ment of RTP header compression, differentiated services, and traffic isolation. We define the format of the RTP protocol header, and dis- cuss issues of backwards compatibility.
