Figure 41: HSMDA Queue Mapping to Scheduler Class Service Lists
To allow for weighted servicing of selected scheduling classes, the port scheduler allows for
two weighted groups to be optionally created (weighted-group-1 and weighted-group-2) and
each may be populated with up to three consecutive scheduling classes (Figure 42). The
group itself maps to the highest inherent strict scheduling level of its member scheduling
classes. Each scheduling class in a scheduling group are individually weighted which allows
for all queues represented by the class to be service according to the ratio of weights based
on the active classes in the group (Figure 43).
