2.9  QOS (Quality of Service) 
The 24G web smart switch provides up to four internal transmit queues per port to support four 
different traffic priorities. High-priority traffic experiences less delay in the switch than that of lower 
priority traffic under congested conditions. This can be critical for congestion sensitive traffic such as 
VOIP. The GSS-24T2SFP web smart switch provides three types of QOS. It can assign packets to one 
of four transmit queues according to 802.1P QOS. If the incoming packet is untagged, the 
GSS-24T2SFP web smart switch uses the priority field in the per-port Default Priority configuration 
screen (Port Config page) to assign the packet to one of four transmit queues. If the incoming packet 
is tagged or priority tagged, the 24G web smart switch uses the priority field in the incoming packet 
tag to assign the packet to one of four transmit queues. 
 
The GSS-24T2SFP web smart switch also provides a remap function. The switch inserts packets into 
the transmit queue based on the priority ID. To extend QOS functionality, administrators can assign a 
map between priority and queues. The switch can handle the packets transmit by the Tx Queue by a 
Weighted Round-Robin algorithm.
