I-jitter nokulahleka kwamaphakethe emkhankasweni we-VPN: yini okufanele iqhathaniswe

Inkulumo efana nerobhothi kanye namagama alahlekile kuzwakala ngendlela ehlukile ngoba kuyizinkinga ezimbili ezihlukene. I-jitter ishintsha ukuthi amaphakethe afika nini; ukulahleka kusho ukuthi awafiki nhlobo. Kokubili kungenzeka ngesikhathi isivivinyo sesivinini sibika ukulanda okunempilo, ngoba umthamo kanye nokulethwa ngesikhathi kulinganisa izinto ezihlukene. Hlanganisa ubufakazi nomsindo ngaphambi kokushintsha noma isiphi isilungiselelo.

Kungani amaphakethe afika emuva nalahlekile kuzwakala ngendlela ehlukile

Imidiya ishiya umthumeli ngejubane elilinganayo, futhi amanethiwekhi angempela ayiletha ngezikhala ezingalingani. Izinhlelo zokusebenza zibeka ibhafa encane ukuze zilungise lokho, zishintsha ukubambezeleka ngokuqhubeka: khulisa ibhafa futhi ingxoxo ibonakala ihamba kancane, yehlisa futhi kuvele izikhala. Iphakethe elifika ngemva kwesikhathi salo sokudlala selilahlekile ngempela, ngisho noma lingakaze lilahliwe. Yingakho ukuxhumana okubili okunobubanzi obufanayo kungaveza izingcingo ezihluke kakhulu.

Indlela nayo ibalulekile. Imidiya engenayo nephumayo ingathatha izindlela ezihlukene, ikakhulukazi lapho uhlangothi olulodwa lusekhoneni leselula.

Izinombolo okufanele zifundwe ngesikhathi esibi

Sebenzisa izibalo zohlelo lokusebenza uqobo lapho zikhona, futhi uzifunde ngesikhathi ucingo lubi, hhayi ngemva kokuphela kwalo. Isidluliseli semidiya ngokuvamile siyisiphathi esihlukile kusayithi yesevisi, ngakho i-ping eya ekhasini lokuqala ilinganisa umzila okungawusebenzisi ucingo. Bheka amaphesenti okulahleka, isikhathi sokuhamba nokubuya kanye ne-jitter ngokwehlukana, futhi bhala ukuthi iklayenti iyayithumela noma iyayithola inkinga. Ukuxhuma kabusha kwe-VPN phakathi nocingo kwisigameko sesithathu okufanele sisetshalwe phansi, hhayi ukuhlanganiswa nezinye.

Izithombe zesikrini zephaneli lezibalo zingcono kunenkumbulo yocingo, ngoba izinombolo zingaqhathaniswa kamuva. Imizuzwana engamashumi amabili yamaphesenti okulahleka ikutshela ukuthi umzila ulahla amaphakethe manje, kodwa hhayi ukuthi ukulahleka kufika ngamaqoqo noma kuqale nini.

Ngakho-ke phinda isilinganiso ngaphansi kwesimo sesibili esikhundleni sokufunda iwindi elilodwa njengesahlulelo. Amawindi amabili athathwe ngaphansi kwezimo ezihlukene akhuluma okuningi kunewindi elide elilodwa elathathwa ngaphandle kwanoma isiphi isimo.

Ibhafa le-jitter lenza ini ngesikhathi sokugcina

Ibhafa le-jitter libamba amaphakethe angenayo isikhashana ukuze ukufika okungalingani — ukushintshashintsha kokubambezeleka okuchazwa yi-RFC 3393 njengesilinganiso — kudlalwe ngokwewashi elivamile. Ubukhulu bebhafa bubeka isikhathi sokugcina sokudlala: iphakethe ngalinye eliza ngemuva kwaleso sikhathi liyalahlwa, noma yikuphi okuqukethwe kulo. Ama-codec ahluka ngokuthi angafihla kangakanani, futhi i-codec efaka ifreyimu elahlekile ingafihla ukulahleka okukodwa kodwa hhayi uchungechunge lwakho. Yingakho amaphesenti afanayo okulahleka enika izinga locingo elihlukile kuma-codec ahlukene.

Ukushuna ibhafa ukushintshana, hhayi ukulungisa. Ibhafa elikhudlwana lithenga ukuqhubeka ngezindleko zokubambezeleka engxoxweni, futhi alikwazi ukubuyisa amaphakethe afika ngemva kwesikhathi.

Qhathanisa umsakazo nomthwalo ngaphambi kokuphuma

Gcina indawo yokuphuma nokuhlelo lokusebenza kungaguquki kuyilapho ushintsha isimo sasendaweni esisodwa ngesikhathi. Isithonjana sesignali esinamandla asisho lutho mayelana nokuminyana kwesiteshi. Uma inkinga ilandela igumbi elilodwa noma indawo yokungena eyodwa, umsakazo uwuphenyo olulandelayo.

ping -c 50 -i 0.2 203.0.113.9
mtr -rw -c 20 203.0.113.9

I-ping inika inani lokulahleka nokuhlakazeka okungaqhathaniswa phakathi kwezimo, kanti i-mtr ikhombisa ukulahleka kuwo wonke amahophu kulo lonke umzila. Amahophu aphakathi ahlulekayo kuyilapho awalandelayo ephendula ngokuvamile ehlisa ukubaluleka kwe-ICMP esikhundleni sokulahla ithrafikhi yomsebenzisi. Phinda kokubili ngesikhathi ukulayisha okulawulwayo kuqhubeka, ngoba isixhumanisi esihle lapho kungasebenzi futhi esingasebenzi ngaphansi komthwalo sikhomba emgqeni wokulinda, hhayi ku-VPN. Uma isimo esisodwa kuphela esiphindayo inkinga, esinye isimo sisanda kukhishwa.

Lungisa kuphela lokho okuqinisekiswa ukuqhathanisa

Ukuqhathanisa ngakunye kuqinisekisa ukulungisa okukodwa, futhi ukusebenzisa eziningi ngesikhathi esisodwa kucekela phansi ubufakazi. Umzila wasendaweni obuthakathaka udinga isiteshi esingcono noma i-Ethernet, ithrafikhi eqhudelanayo idinga ukuhlela noma isimiso somgqeni, futhi indawo yokuphuma embi eyodwa idinga ukuqhathanisa enye indawo yokuphuma ngaphansi kwezimo ezifanayo. Lapho ushintsha ukuthutha kwe-VPN, gcina iphrofayela isemthethweni futhi ushintshe ukuguquguqukayo okukodwa ngesikhathi. Phinda uhlole ingxoxo efanayo ngomsebenzi ojwayelekile wangemuva esikhundleni sokwahlulela impumelelo ngokuthi amaphuzu esivivinyo sesivinini enyukile.

Bhala phansi indlela, ukulahleka, i-jitter, isikhathi sokuhamba nokubuya kanye nesimo okulinganiswe ngaphansi kwaso ngakunye. Lelo rekhodi liguqula isikhalo esingacacile mayelana nezinga locingo sibe ukutholakala umuntu angathatha isinyathelo ngakho. Kugcine netikithi ukuze ukuqhathanisa okulandelayo kuqale emgqweni ofanayo wesisekelo.
