Ukushintsha i-QoS (Izimiso Zokusebenza) ikhombisa teknoloji ebalulekileyo yokuphepha inethiwekhi, eyiphiqiza kanye nokuphepha uhlelo lwedatha ukuze iqinise ukusebenza okuhle kwenethiwekhi. Le ndawo encane yindlela ekuvumela abaphathi benethiwekhi ukwabelana nezimali zebandwidth ngendlela efanelekileyo, futhi wenze amathuba okuqala ohlelo lwenethiwekhi ngokwemigomo yezi hlelo lokuqala. Lapha phakathi kwezinye izindawo zase-Layer 2 ne-Layer 3 yenani le-OSI, ukushintsha i-QoS isebenzisa izinkomba eziningi njenge-selwa le traffic, ukuthunyelwa, ukuscedula, nokuphepha ukungcola. Lo msebenzi wahlukanisa izinhlobo eziningi zetraffic, njengokuthula, ividiyo, ne-data, futhi akunciphise amathuba angcono kuwo onke. Ngokusebenzisa imithwadi emibili yesikhombisi, uyiphatha ukulayisha iphetjhana, ukuqiniseka ukuthi izicelo eziphambene nazo ziphumo ebandwidth elidingekayo futhi ukukhishwa kwezitraffic engadingeki kungcolise inethiwekhi. Ukushintsha i-QoS usebenzisa izindlela eziningi zokuthunyelwa, njenge-selwa se-priority selide, weighted round-robin, ne-weighted fair queuing, ukuze kuthuthuke ukulayishwa iphetjhana. Lezi zinkomba zihlanganisa ukwenza ukuthonya okuncane, ukwehlisa ukungena kwezephetjhana, futhi uvikele ukusebenza okuphephile kwenethiwekhi noma lapho kunezinga eliphezulu lokungcola. Lo msebenzi ungasiza kakhulu ezindleleni eziningi zokumaka nokuhlukanisa, njenge-DSCP (Differentiated Services Code Point) ne-CoS (Class of Service), ukuze kwenzeke ukuphepha kahle kwetraffic phakathi kwezinethiwekhi ezinhlelweni.
