?– Admitted QoS Parameter Set This set defines the parameter sets for which
resources have been allocated and reserved. This also means that the service has
been admitted and can make use of the resources allocated to it at any time. It
does not necessarily mean that the resources are actually being used to serve the
service flow. If a flow is not using all the resources reserved for it, the network may
temporarily reallocate the excess resources to other flows whose resource utilization
may be exceeding what is reserved for them. However, as long as a service flow
is using all its reserved resources, a network would not reallocate those resources
to serve the excess needs of other service flows. A service flow that has this parameter
defined but has its Active QoS Parameter set to null is called an admitted
service flow.
?– Active QoS Parameter Set This parameter set defines the parameter set for
which resources are reserved and actually being used. Only flows that have active
QoS parameters defined can request and be granted bandwidth for transmission.
A service flow for which this parameter is defined is called an active service flow.
