Quality of Service Mechanism Selection in the Session Description Protocol
RFC 5432, “Quality of Service Mechanism Selection in the Session Description Protocol”, is a Proposed Standard document published in March 2009 by J. Polk, S. Dhesikan, G. Camarillo. The canonical text is published by the RFC Editor.
Abstract
The offer/answer model for the Session Description Protocol (SDP) assumes that endpoints somehow establish the Quality of Service (QoS) required for the media streams they establish. Endpoints in closed environments typically agree out-of-band (e.g., using configuration information) regarding which QoS mechanism to use. However, on the Internet, there is more than one QoS service available. Consequently, there is a need for a mechanism to negotiate which QoS mechanism to use for a particular media stream. This document defines such a mechanism. [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.
