The Session Description Protocol Label Attribute
RFC 4574, “The Session Description Protocol Label Attribute”, is a Proposed Standard document published in August 2006 by O. Levin, G. Camarillo. The canonical text is published by the RFC Editor.
Abstract
This document defines a new Session Description Protocol (SDP) media-level attribute: "label". The "label" attribute carries a pointer to a media stream 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 streams. The application can then use the provided pointer to refer to each particular media stream in its context. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
