Kwi-intanethi ye-intanethi, i- ping yindlela ethile yokuthumela imilayezo esuka kwikhompyutyana ukuya kwelinye njengenxalenye yoxinzelelo lwe-Intanethi ye-Intanethi ye-Intanethi (IP) . Uvavanyo lwe-ping lunquma ukuba ngaba umthengi wakho (ikhompyutha, ifowuni, okanye ifowuni efanayo) unokunxibelelana nesinye isixhobo kwinethiwekhi.
Kwiimeko apho uqhagamshelwano lwenethwekhi lusekwe ngempumelelo, iimvavanyo ze-ping nazo zinokumisela ukuxhumeka kwe- latency (ukubambezeleka) phakathi kwezixhobo zombini.
Qaphela: Iimvavanyo ze-Ping azifani neemvavanyo zentsholongwane ze- intanethi ezichonga ngokukhawuleza ukuba uxhumano lwakho lwe-intanethi luhambelana newebhusayithi ethile. I-Ping ifanelekile ukuvavanya ukuba ngaba unxibelelwano lungenziwa, okanye kungekhona ukuxhamla ukuxhunywa.
Indlela yovavanyo lwePing
I-Ping isebenzisa iProsoft Control Message Protocol (ICMP) ukudala izicelo kunye nokusingatha iimpendulo.
Ukuqala uvavanyo lwe-ping uthumela imiyalezo ye-ICMP esuka kwisixhobo sendawo ukuya kude. Isixhobo sokufumana sivuma imilayezo engenayo njenge-ICMP ping isicelo kunye nezimpendulo ngokufanelekileyo.
Ixesha elidlulileyo phakathi kokuthumela isicelo kunye nokwamkela impendulo kwisixhobo sendawo senza ixesha le- ping .
Indlela yokusebenzisa ii-Ping Networked Devices
Kwi-Windows operating system , umyalelo we- ping usetyenziselwa ukuhlola iimvavanyo ze-ping. Yakhelwe kwinkqubo kwaye iyenziwa nge- Prompt Command . Nangona kunjalo, ezinye iinkonzo ezisebenzayo nazo zifumaneka ngokukhululekile ukukhuphela.
Idilesi ye-IP okanye igama lomninimzi wefowuni efunekayo ukuba liyaziwa. Oku kuyinyaniso ukuba ingaba ifowuni yangasemva komnatha iya kukhankanywa okanye ingaba iseva yewebhu. Nangona kunjalo, ngokuqhelekileyo, idilesi ye-IP isetyenziselwa ukuphepha imiba kunye ne- DNS (ukuba i-DNS ayifumane idilesi ye-IP efanelekileyo kwigama lomninimzi, umcimbi unokuphumla kunye neseva ye-DNS kwaye kungekhona ngefowuni).
Umyalelo we-Windows wokuqhuba uvavanyo lwe-ping ngokubhekiselele kwi-router nge-192.168.1.1 Idilesi ye-IP iya kubonakala ngathi:
192.168.1.1I- syntax efanayo isetyenziselwa ukuyibeka iwebhusayithi:

Indlela yokufunda i-Ping Test
Ukusebenzisa umzekelo wesibini ovela phezulu kunokuvelisa iziphumo ezinjengale:
Pinging [151.101.1.121] nge 32 bytes yedatha: Phendula ku-151.101.1.121: bytes = 32 ixesha = 20ms TTL = 56 Phendula ukusuka ku-151.101.1.121: bytes = 32 ixesha = 24ms TTL = 56 Phendula ukusuka ku-151.101.1.121: bytes = Ixesha eli-32 = 21m TTL = 56 Phendula ukusuka ku-151.101.1.121: bytes = 32 ixesha = 20ms TTL = 56 Amanani e-Ping kwi-151.101.1.121: Iipakethi: I-Sent = 4, ifunyenwe = 4, ilahlekile = 0 (0% ilahleko), malunga neenxa zonke amaxesha okuhamba ngee-milli-seconds: Minimum = 20ms, Maximum = 24ms, Umyinge = 21mIdilesi ye-IP eboniswe ngasentla ingeyo, yintoni umyalelo we-ping ohlolwe ngayo. I- bytes ezingama-32 zibukhulu besikhombisi, kwaye zilandelwa ngethuba lokuphendula.
Isiphumo sovavanyo lwe-ping luyahlukahluka kuxhomekeke kumgangatho woxhumano. Inxibelelwano ye-intanethi ye-intanethi (intambo okanye i-wireless) ngokuqhelekileyo ibangela ukulandelwa kwe-ping test latency engaphantsi kwe-100 ms, kwaye kaninzi iphantsi kwe-30 ms. Uxhumo lwe- intanethi ye-intanethi ngokuqhelekileyo luba ne-latency ngaphezu kwe-500 ms.
Jonga isikhokelo sethu malunga nendlela yokwenza ikhompyutha okanye iwebhusayithi ukuba ufunde kabanzi malunga neziphumo zovavanyo lwe-ping.
Ukulinganiselwa kwePing Testing
I-Ping ilungisa ngokuchanekileyo uqhagamshelwano phakathi kwezixhobo zombini ngexesha lovavanyo luqhutywa. Iimeko zomnatha ziyakushintsha kwesaziso somzuzu, nangona kunjalo, ngokukhawuleza ukwenza iziphumo zokuvavanya zangasese ziphelile.
Ukongezelela, iziphumo zeemvavanyo ze-intanethi zihluke kakhulu kuxhomekeke kwiseva ejoliswe kuyo. Ngexesha elifanayo, i-ping numbers ingaba yinto enhle kwiGoogle kwaye kodwa iyingozi kwiNetflix.
Ukuze ufumane ubuninzi bexabiso ukusuka kuvavanyo lwe-ping, khetha izixhobo zokusebenzisa izixhobo ezilula ukuyisebenzisa kwaye uzibonise kwiiseva ezifanelekileyo kunye neenkonzo malunga noko uhlangabezana neengxaki.
