Abstract Abstract
The offer/answer model for SDP assumes that endpoints establish, The offer/answer model for SDP assumes that endpoints establish,
somehow, the QoS required for the media streams they establish. somehow, the QoS required for the media streams they establish.
Endpoints in closed environments typically agree out of band (e.g., Endpoints in closed environments typically agree out of band (e.g.,
using configuration information) which QoS mechanism to use. using configuration information) which QoS mechanism to use.
However, on the Internet, there is more than one QoS service However, on the Internet, there is more than one QoS service
available. Consequently, there is a need for a mechanism to available. Consequently, there is a need for a mechanism to
negotiate which QoS mechanism to use for a particular media stream. negotiate which QoS mechanism to use for a particular media stream.
