SettingupanHSUforQoS
4.Foreachqueue,bothdownlinkanduplink(fromtheHSU)entertherequiredweight
andMIR.Thelattermaybeleftunlimited.inwhichcasethesystemwillusea“best
effort”method.
Ifyouexceed100%totalweight,youwillreceiveanerrormessage.
Youwillberequiredtocorrectthisbeforeleavingthewindowotherthanbycancel‐
lation.
Ifyouareunder‐booked,forexamplebysettingaqueuetozero,theunusedweight
willbedistributedtotheremainingqueues.Theeffectofdoingthiswillonlybecome
apparentundercongestion.Inparticular,aqueuesettozeroweightwillbecome
nearlyblockedundercongestionwithpacketspassingthroughonabesteffortbasis.
5.UsingtheConfigurableTTL:ConfigurableTime‐to‐Live(TTL)istypicallyusedfor
streamingapplicationslikemannedvideosurveillance.Apack etnottransmitted
withintheTTLperiodinacongestedlinkisdropped.In
themannedvideo
surveillanceexample,thelossofpacketsundercongestionislessimportantthan
acquiringthemostrecentpack ets.ThechoiceoftheTTLdurationistherefore,
dependentonthetoleranceoftheuserapplicationtotransmission“glitches”.
6.Whenyoucompleteyourentries,clickOKtosavethemand
continue.
