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.  

This document is a product of the Multiparty Multimedia Session Control Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
status of this protocol.  Distribution of this memo is unlimited.
