10.1 Briefoverviewofthequalityofservicesection
PMP320providesdifferentqualityofservice(QOS)settingsperthe802.16e
specificatione.gUGS,rtPS,nrtPSandBE.UsercanchoosetheappropriateQoS
profilebasedontheapplicationneeds.ItisrecommendedthateachQoSprofileis
createdwithspecificMaximumInformationRate(MIR)andCommitted
InformationRate(CIR)asdictatedbytheapplicationneeds.ThePMP320system
cansupportseveralQoSprofiles(e.g.256)withdifferentcombinationsofQoS
types,MIRandCIR.

EachPMP320APservesseveralCPEsundergivensector.EachCPEcouldhave
multipleserviceflowsinbothULandDLdirection.Eachflowisassociatedwitha
givenQoSprofilewhichisconfiguredbasedonenduserneed.OneCPEcouldhave
multipleflowstoservedifferentapplicationssimultaneously.Todifferentiate
multipleflowsunderasingleCPE,PMP320usesclassificationprofiles.These
classificationprofilesareassociatedwithspecificserviceflows.Different
applications,bothoverULandDLcansendtheirdatausingclassificationswhich
helpsCPEandAPtoassociatedatatraffictospecificserviceflowwithQoStype.
PMP320supportssource/destinationIPaddressandTOS/DSCP(DiffServeCode
