Hauv computer kev sib tham, ping yog ib hom kev xa tawm cov lus sib txuas ntawm ib lub hauv computer mus rau lwm qhov teebmeem kev sib tham ntawm Internet Protocol (IP) . Ib qho kev xeem ping txiav txim seb koj tus neeg tau txais kev pab (lub computer, xov tooj, lossis lwm yam khoom siv) tau sib txuas lus nrog lwm lub tshuab thoob plaws lub network.
Thaum muaj kev sib txuas lus hauv kev sib txuas lus hauv network, ping kev ntsuam xyuas kuj tuaj yeem txiav txim siab txog qhov txuas kev qeeb (qeeb) ntawm ob qho khoom siv.
Lus Cim: Ping tests tsis zoo li kev sib tw hauv internet uas txiav txim siab npaum li cas koj qhov kev txuas hauv internet yog tawm tsam ib lub website. Ping yog qhov tsim nyog los ntsuam xyuas seb puas muaj kev sib txuas tau, los yog tsis ntev npaum li cas txoj kev txuas.
Cas Ping Cov Kev Ua Haujlwm
Ping siv Internet Kev Txhim Kho Xov Tooj (ICMP) los tsim cov lus thov thiab tuav cov lus teb.
Pib lub ping test xa ICMP cov lus ntawm lub zos cov cuab yeej mus rau cov chaw taws teeb. Tus neeg tau txais kev pab pom tau tias cov khoom xa tuaj raws li lub ICMP ping thov thiab teb raws li.
Lub sij hawm dhau mus ntawm kev xa cov lus thov thiab tau txais daim ntawv teb ntawm lub zos ntaus ntawv muab lub sij hawm ping .
Yuav ua li cas Ping Networked Devices
Hauv Windows operating system , qhov ping command yog siv los khiav ping tests. Nws yog built-in rau lub system thiab yog executed los ntawm kev hais kom ua kom tiav . Txawm li cas los xij, lwm cov kev pabcuam kuj muaj kev ywj pheej rau kev siv.
IP chaw nyob los sis hostname ntawm tus rau-yuav-pinged ntaus ntawv yuav tsum tau paub. Qhov no muaj tseeb tiag txawm tias cov khoom siv hauv zos tom qab lub network yuav raug muab pinged los yog nws yog ib qhov chaw hauv lub website. Txawm li cas los, feem ntau, tus IP chaw yog siv los tiv thaiv cov teeb meem nrog DNS (yog tias DNS tsis pom qhov chaw tus IP zoo los ntawm lub hostname, qhov teeb meem yuav so nrog lub DNS neeg rau zaub mov thiab tsis tas nrog tus ntaus ntawv).
Lub Xeev cov lus txib rau khiav lub ping test tiv thaiv ib router nrog lub 192.168.1.1 IP chaw nyob yuav zoo li no:

Yuav Nyeem Li Cas Ping Test
Kev ua txhaum thib ob ntawm qhov saum toj no yuav ua tau zoo li no:
Pinging [151.101.1.121] nrog 32 bytes ntawm cov ntaub ntawv: Teb ntawm 151.101.1.121: bytes = 32 zaug = 20ms TTL = 56 Teb ntawm 151.101.1.121: bytes = 32 lub sij hawm = 24ms TTL = 56 Teb ntawm 151.101.1.121: bytes = 32 sij hawm = 21ms TTL = 56 Teb ntawm 151.101.1.121: bytes = 32 zaug = 20ms TTL = 56 Ping txheeb cais 151.101.1.121: Packets: Sent = 4, Txais = 4, poob = 0 (0% poob), kwv yees puag ncig lub sij hawm rau hauv cov vev voog: Hom = 20ms, Tshaj siab = 24ms, Nruab nrab = 21msIP chaw nyob saum toj no belongs rau, uas yog yam ping command test. Lub 32 bytes yog qhov loj me me, thiab nws tau ua raws li lub sij hawm teb.
Qhov tshwm sim ntawm qhov ping test txawv nyob ntawm seb qhov zoo ntawm txoj kev txuas. Ib qhov zoo sib txuas hauv internet (wired lossis wireless) feem ntau tshwm sim hauv ping kuaj latency ntawm tsawg dua 100 ms, thiab feem ntau tsawg dua 30 ms. Ib qho kev sib txuas hauv satellite tshaj li niaj zaus los ntawm latency saum toj no 500 ms.
Saib peb phau ntawv qhia txog yuav ua li cas rau ping lub computer los yog lub website kom paub ntau ntxiv txog cov txiaj ntsim ntawm ping test.
Cov kev txwv ntawm Ping Testing
Ping yog ntsuas kev sib txuas ntawm ob qho khoom siv thaum lub sijhawm ib qho kev xeem khiav. Cov xwm txheej hauv lub network tuaj yeem hloov tau ib ntus tsab ntawv ceeb toom, txawm li cas los xij, sai sai ua rau cov kev xeem qub dhau los lawm.
Tsis tas li ntawd, cov kev sib tw hauv internet ping sib txawv nyob ntawm seb lub hom phiaj ntawm qhov kev xaiv uas tau xaiv. Tib lub sijhawm, ping statistics yuav zoo rau Google thiab tab sis phem rau Netflix.
Txhawm rau tau tus nqi siab tshaj plaws ntawm ping testing, xaiv cov cuab yeej ping uas yooj yim los siv thiab taw tes rau ntawm cov kev pabcuam thiab cov kev pabcuam rau qhov koj muaj teebmeem.
