RFC 5888 defines a mechanism for semantically grouping media sections in the Session Description Protocol (SDP). One difficulty that has arisen in several applications of SDP is the need to uniquely identify these groups either in other protocols or elsewhere in the SDP itself. This document proposes a simple, backwards-compatible mechanism that provides unambiguous identifiers for RFC 5888 groups. This document updates RFC 5888.
