QoS

Quality of Service (QoS) provides the ability to implement

priority queuing within a network. QoS is a means of

providing consistent and predictable data delivery to

the Switch by distinguishing between packets that have

stricter timing requirements from those that are more

tolerantofdelays.QoSenablestrafctobeprioritizedwhile

avoidingexcessivebroadcastandmulticasttrafc.Trafc

such as Voice and Video streaming which require minimal

delays can be assigned to a high priority queue, while other

trafccanbeassignedtoalowerpriorityqueue,resulting

inuninterruptedactions.WithoutQoS,alltrafcdataisas

likely to be dropped when the network is congested. This

can result in reductions in network performance and hinder

the network in time-critical situations.

In a Switch, multiple queues per port are often provided

to give preference to certain packets over others based

on user-dened criteria. When a packet is queued for

transmission within a port, the rate at which it is processed

dependsonhowthequeueisconguredandtheamount

oftrafcpresentwithinotherqueuesontheport.Ifadelay

is necessary, packets are held in the queue until they are

authorized for transmission.

Global Settings

There are two options for applying QoS information onto

packets:the802.1pClassofService(CoS)priorityeld

within the VLAN tag of tagged Ethernet frames, and Dif-

ferentiated Services (DiffServ) Code Point (DSCP). Each

portontheSwitchcanbeconguredtotrustoneofthe

packetelds(802.1p,DSCPorDSCP+802.1p).Packets

that enter the Switch’s port may carry no QoS informa-

tion as well. If so, the Switch places such information

into the packets before transmitting them to the next

node. Thus, QoS information is preserved between nodes

within the network and the nodes know which label to

giveeachpacket.Atrustedeldmustexistinthepacket

for the mapping table to be of any use. When a port is

conguredasuntrusted,itdoesnottrustanyincoming

packet priority designations and uses the port default

priority value instead to process the packet.
