Establishing multimedia streams must take into account requirements
for end-to-end QoS, authorization of network resource usage and
accurate accounting for resources used.  During session set up,
policies may be enforced to ensure that the media streams being
requested lie within the bounds of the service profile established
for the requesting host.  Similarly, when a host requests resources
to provide a certain QoS for a packet flow, policies may be enforced
to ensure that the required resources lie within the bounds of the
resource profile established for the requesting host.

To prevent fraud and to ensure accurate billing, this document
describes various scenarios and mechanisms that provide the linkage
required to verify that the resources being used to provide a
requested QoS are in-line with the media streams requested (and
authorized) for the session.
