ScopeofthisChapter
UseofSmartBandwidthManagement(SBM)asatooltoenhanceresourceutilization
involvesnetworkmanagementissuesbeyondthescopeofaUserManual.Whatwewi lldo
here,isshowhowSBMisconfiguredanddemonstrateseveralbasicscenarios.Ourintentisto
“getyoustarted”withSBMbyassistingyoutodevelopyourownintuitionandnetworking
skillssettinguphighlyresourceefficientsectors.
ThefirstpointtokeepinmindisthattheSBMmechanismisalwaysactiveintheHBS.It’snot
somethingyoucanswitchonorswitchoff.
Theissuehereishowtogetthebestoutofit.
TerminologyandConcepts:Recapitulation
Itisimportantbothinfollowingthediscussionbelow,andviewingtheRADWINManager
Utilizationwindowstoremember:
» DownlinktrafficisdatatransferfromanHBStoanHSU
» UplinktrafficisdatatransferfromanHSUtoanHBS
» TheHBSallocatestimeslotstosectorHSUsinround‐robinfashiontoeffecttime‐shar‐
ing.Thereareseparatesetsof64timeslotsforeachoftheuplinkanddownlinkdire c‐
tions.OnetimeslotineachdirectionisreservedforSBMmanagementleaving63in
eachdirectiontobeallocatedtosectorHSUs.Theuplinkanddownlinkallocationsare
independentandthereforesepa ratelyassignable.
» ForeachfixedornomadicHSU,Assuredthroughputisdeterminedbytheactualnum‐
beroftimeslotsallocatedtoitineitherdirection.Peakthroughput(higherthan
Assuredthroughput)maybeachievedbyallocatingunuseddownlinktimeslotsor
unallocateduplinktimeslotstoverybusyHSUs.
» Timeslotallocationistheonlymechanismavailableforutilizationmanagement.
» Manualtimeslotallocation forafixedHSUiscarriedoutduringregistrationorSer‐
