TCP/IPandotherSLAConsiderations
Figure10‐25:Example3:Halftheuplinktimeslotsreservedat40MHzCBW
At40MHzchannelbandwidth,thesectorutilizationisaround70%intheuplinkdirectionand
abbot26%intheuplinkdirection.Thepercentagesectorutilizationhasdroppeddramatically
forthesametrafficload.
TCP/IPandotherSLAConsiderations
TheforegoingexamplewereallbasedonUDPtraffic.IfthesectortraffichasaheavyTCP/IP
content(includingdependentprotocolssuchasHTTP/HTTPS)youmustallowsufficienttime
slotsparticularlyintheuplinkdirectiontoensurethethatTCP /IPACKmessagesare
transmittedwithoutdelay.Sometheoreticalcalculationsarepossible,butultimatelyyouwill
needtouseahardwaretrafficgeneratortoassistyourtimeslotallocation.Thisisparticularly
criticalifyouareoperatingasectorwithSLA.
Thesameholdstrueifyouareofferingabackhaulser vicewithSLAregardlessofthetraffic
pack etcomposition.
