“…The scalable DS technique gives the ability to distinguish among the needs of different interactive multimedia applications. Different applications have different QoS needs depending on the composition of the multimedia; provisioning resources for some applications may be easier than others, some applications have known and predictable behavior, like packet size, traffic volume, and traffic behavior, where others have many variables that makes it extremely difficult to configure traffic conditioning thresholds, maximum queue size, and bandwidth limits for high priority queues [2].…”
