This document defines a new Session Description Protocol (SDP) media-level attribute: 'label'. The 'label' attribute carries a pointer to an application layer media stream identifier in the context of an arbitrary network application that uses SDP. The sender of the SDP document can attach the 'label' attribute to a particular media stream or media streams. The application receiving the SDP document can then associate the particular media stream with its application semantics or role.
