Iyini i-Quality of Service (QoS)?
I-QoS imelela i-Quality of Service. Leli gama eliyinkimbinkimbi ngoba kungekho ncazelo ephelele. Kuye ngokuthi kuphi, kanjani nokuthi kungani isetshenzisiwe, abantu bayakubona ngama-angles ahlukene futhi banokuqonda okuhlukile.
Incazelo ejwayelekile kunazo zonke esinayo ye-QoS yindlela yokwahlukana phakathi kwezinhlobo zethrafikhi nezinhlobo zamasevisi ukuze izinhlobo ezahlukene zesevisi kanye nomgwaqo zingaphathwa ngendlela ehlukile. Ngale ndlela, uhlobo olulodwa lungavunyelwa ngaphezu kwesinye.
I-QoS idinga kakhulu kuma- LAN ezinkampani, amanethiwekhi wangasese nama-intranethi ( amanethiwekhi wangasese axhumanisa izingxenye zezinhlangano) kunama- intanethi kanye ne-ISP amanethiwekhi. Isibonelo, cishe uzobona i-QoS isetshenziselwa i-campus lapho abafundi be-dorm bedlala khona isigamu sempilo phezu kwe-LAN campus, ngaleyo ndlela baxhuma inethiwekhi futhi bevimbela ithrafikhi kwezinye izinhlobo ezibalulekile zedatha.
Ukuthunyelwa kwe-QoS, kulesi simo, kungenza umgwaqo ube yinto ebaluleke kakhulu ehhovisi le-office ngokulimaza imidlalo yokudlala encane, ngaphandle kokubulala okwedlule. Ngakolunye uhlangothi, ukuvula i-intanethi yomhlaba wonke, kuningi isikhathi kungekho QoS yangempela (ngaphandle kokuthi i-ISP yakho isebenzise izindlela ze-QoS).
Ngakho-ke, ukuthi uyashesha kanjani ukudweba umsindo, umbhalo noma ividiyo yevolumu ngokuvamile kuxhomeke kunqwaba yezindaba. Umbhalo ufika kuqala, ngokwemvelo. Uma i-ISP yakho inikeza i-QoS, ithi, ukuthanda izwi, izwi lakho lokuthola izwi liyoba lihle, futhi kuye ngokuthi ububanzi bakho buni, ezinye izinhlobo zabezindaba zingase zihlupheke.
I-QoS iyithuluzi elibalulekile lokuphumelela kwe-VoIP. Phakathi neminyaka yezinhlelo ze- QoS seziye zaba yinkimbinkimbi ngokwengeziwe. Manje, ungaba nezinqubo ze-QoS ze- LAN ezincane kuya kumanethiwekhi amakhulu.
Iyini i-Quality?
Ekuxhumaneni, ikhwalithi ingasho izinto eziningi. Nge-VoIP, ikhwalithi isho ukukwazi ukulalela nokukhuluma ngezwi elicacile futhi eliqhubekayo, ngaphandle komsindo ongafuneki. Ikhwalithi incike kulezi zici ezilandelayo:
- ukulahlekelwa kwedatha
- izici zokubambezeleka okuqhubekayo (okuthiwa i-jitter)
- i-latency , eholele ekukhokheni

Iyini isevisi?
Isevisi ingasho izinto eziningi ekuxhumaniseni, njengoba ithatha ukungaboni kahle ngencazelo. Nge-VoIP, ngokuvamile kusho lokho okunikezwa abathengi ngokwezakhiwo zokuxhumana.
I-Bandwidth
Njengoba ngikhuluma izikhathi eziningi kangaka, into yokuqala okudingeka uqiniseke ukuze uqiniseke ukuthi izinga leVoIP lingumkhawulokudonsa okwanele. Futhi lokhu kungenye yezinselele ezinkulu kunamanethiwekhi namuhla: indlela yokufeza izinga elihle lezwi elinomkhawulokudonsa olinganiselwe futhi ohlanganyelwe njalo. Yilapho i-QoS iqala khona.
Isibonelo: Inhlangano yakho idlulisa i- VoIP phezu kwe-LAN yangasese , ebuye ibeke ezinye izinhlobo zedatha - ngokufakela, ukulayisha, ukuthumela ngefeksi, futhi ngezinye izikhathi ukudlala imidlalo ye-LAN (ikakhulukazi uma wena, umphathi, engekho). I-QoS ukukhetha enye yalezi zigaba zamasevisi phezu kwabanye kuye ngezidingo zakho. Isibonelo, uma ufuna ikhwalithi enkulu ye-VoIP , noma ngabe lokhu kusho ukudela ezinye izinhlobo zedatha, khona-ke ungakwazi ukulungisa izilungiselelo ze-QoS njengokuthi idatha yezwi iyakwamukela ngenethiwekhi.

Ukuze ukwazi ukuthola ukuthi umkhawulokudonsa unayo ufanelwe yini nge-VoIP, ungaba nomkhawulokudonsa wakho kubalwa. Kunezindawo eziningi kuwebhu lapho ungakwenza khona lokhu mahhala.
Indlela yokufeza i-QoS?
Ngezinga lomuntu siqu (elincane), i-QoS isethwe ezingeni le-router. Uma ufuna ukuphoqelela izinqubomgomo ze-QoS kunethiwekhi yakho, qiniseka ukuthi usebenzisa router ehlome isofthiwe ye-QoS, ongayisebenzisa ukulungisa ikhwalithi yenkonzo oyidingayo.
Uma ungumsebenzisi ngamunye, khona-ke kunethuba elikhulu ukuthi umnikezeli wakho wesevisi weVoIP usevele esebenzisa i-QoS kuseva yabo, nakuba lokhu kungeyona into njalo. Ngale ndlela, ukulungiswa kwe-QoS kuyoba njengokuthi bayathanda izwi ngaphezu kwezinye izinhlobo zedatha. Kodwa-ke, njengoba uzobe usebenzisa uxhumano lwe- intanethi kusuka kumhlinzeki wolunye uhlobo (i-ISP yakho), umphumela uhlanjululwa; ngaphandle kokuthi usebenzise i-QoS ku- ATA yakho noma ku-router. Amanye amafoni we-IP avumela lokhu futhi.
