Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mumwe muenzaniso unogombedzera wokudikanwa kweQoS paInternet une chokuita nokuputsika kwemotokari. Indaneti inotsamira pamitemo yokudzivisa kuwanda kwemotokari, sezvakagadzirwa muTransmission Control Protocol (TCP), kuderedza motokari mumamiriro ezvinhu aizotungamirira ku"kuparara". QoS mafomu, akadai VoIP uye IPTV, zvinoda zvikuru kuramba bitrates uye yakaderera latency, saka havagoni kushandisa TCP uye havagoni zvimwe kuderedza kwavo motokari mwero kubatsira kudzivirira congestion. QoS zvibvumirano zvinogumira traffic iyo inogona kupihwa kuInternet uye nekudaro inosimbisa traffic kuumba iyo inogona kudzivirira kuti isanyanya kuremerwa, uye nekudaro chikamu chakakosha chekugona kweInternet kubata musanganiswa wenguva chaiyo uye isiri-chaiyo nguva traffic pasina kunyungudika.  Mubvunzo: Zvikumbiro zveQoS zvinoda zvinhu zvipi zviviri kuti zvishande zvakanaka?
zvikuru nguva dzose bitrates uye yakaderera latency
