Unified Scheduling
WFQ with weights assigned to each guaranteed flow and to the predictive+datagram pseudo flow 0
Multiple priorities within flow 0
FIFO+ within each priority level
Priority scheduling shifts jitter from higher priority to lower priority
Put datagram traffic at lowest priority level
Each priority level has a target delay bound
Make jitter shifted from higher priority classes small by choosing target delay bounds widely spaced (at least order of magnitude), thus good isolation
