others,andassuchtheethernetnetworkplacesatagoneachpacketrepresentingitspriority.
TheRADWINQualityofServicefeature(QoS)canworkwithtwodifferentstandardsoftraffic
prioritization:VLAN(IEEE802.1q/p)andDiffserv(RFC2475).Eachofthesestandardsdivides
theprioritiesdifferently:VLANuses8levels,whileDiffservuses64levels.
RADWINequipmentcanrecognizethesenetworkprioritytags,andcanplacethetrafficin
oneof4differentQoSprioritylevels,asshowninTable 4‐1:
Thatis,ifworkingwiththeDiffservstandard,traffictaggedwithprioritylevelsfrom48to63
aretreatedas“RealTime”,thosewithlevelsfrom47to32aretreatedas“Nearrealtime”,etc.
TheRADWINQualityofServicefeature(QoS)allowsyoutochangewhichstandardpriority
levelistranslatedintoaprioritylevelusedinRADWINequipment.
Example:Ifyouknowyournetworkwillhaveagreatdealofhigherprioritytraffic,butyou
onlywantthehighesttoreceivepreferentialtreatment,youcandefine“RealTime”as
beingfrom55to63,insteadofthedefaultvalues48‐63.Youmustcoveralllevels,soin
thiscase,makesuretore‐define“NearRealTime”as32to54.
Percentages:Youcanseteachprioritylevel(intheuploadanddownloaddirectionseparately)
totakeupacertainpercentageofthetotaltraffic,solongasthatpercentageaddsupto100.
MIR:Youcanalsoplaceanabsolutemaximumlimitontheamountoftrafficallowedtopass
perprioritylevel,nomatterhowmuchtrafficcomesthrough.
SettingupQoS
QoSforTransportationFiberinMotionissetupintwophases:
1. ChoosetheQoSprioritystandard:Projecttab,uppertable,QoSMode
(ChooseNone,VLAN,orDiffserv)
Thelowertablewillshowthedefaultvaluesaccordingtothestandardyouhavechosen.
2. Configurethevaluesforeachqualitygroup:Projecttab,lowertable:
Table4‐1:DefaultprioritiesandallocationbyVLANvs.Diffserv
