public class PriorityScheduler

extends DiffServPacketScheduler

In priority-based scheduling the higher priority packet flow exclusively use the bandwidth regardless the of the lower-priority queue status. For priority packet scheduling, each class-type is specified with scheduling priority at ActionProtile section of DML.
