Weighted Round Robin (WRR)
WRR processes packets as much as weight. Processing the packets that have higher
priority is the same way as strict priority queuing. However, it passes to next stage after
processing as configured weight so that it is possible to configure for packet process to
the packets having higher priority. However, there’s a limitation of providing differentiated
service from those existing service.
