Ping ihlaba umhlaba wonke ngasikhathi sinye
Amathuluzi amaningi e-ping ahlola iseva eyodwa bese ekunika inombolo eyodwa. Leli lithuluzi lihlukile: kusuka kubrawuza yakho, lifinyelela kumaseva angaphezu kuka-70 e-speedor.net kuwo wonke amazwekazi, alinganise isikhathi impendulo ngayinye ethatha sona, bese lihlela uhlu ukuze indawo esheshayo kunazo zonke ihlale phezulu. Umphumela ngamunye ubonisa ifulegi lezwe kanye nombala, oluhlaza kusho ukuthi kushesha, ophuzi kusho ukuthi kusesezingeni eliphakathi, obomvu kusho ukuthi kuyahamba kancane, ngakho ufunda konke ngoxhumano lwakho nomhlaba emizuzwaneni.
Lowo mbono wembulweni jikelele uwusizo ngempela. Uma ukhetha iseva yomdlalo, isifunda sekholi yevidiyo, noma indawo yokugcina okuthile, awudingi ukuqagela ukuthi yiziphi izindawo eziseduze ngokwenethiwekhi. Ubuka nje. Ibanga lenethiwekhi alifani nebanga lemephu, yingakho ukuhlola izindawo eziningi kudlula ukuqagela.
Ukuthi i-ping ne-latency kusho ukuthini ngempela
I-Latency yisikhathi sokulibala phakathi kokuthumela isicelo nokuthola impendulo. I-Ping yigama elivamile lokukala leso sikhathi sokulibala, futhi inombolo oyitholayo yi-round-trip time (RTT), isikhathi iphakethe elincane elithatha sona ukuhamba liye eseva libuye. Abantu basebenzisa la magama womabili ngokushintshaniswa, futhi lokho kulungile ekwenzekeni. Kunoma yikuphi, kulinganiswa nge-millisecond (ms), futhi inombolo ephansi ihlale ingcono.
Iqiniso elilodwa: i-ping yangempela kukhompyutha yakho isebenzisa i-ICMP, iphrothokholi esezingeni eliphansi ababrawuza abavunyelwe ukuyithumela. Ngakho leli thuluzi lilinganisa uhambo lokuya nokubuya lwe-HTTP esikhundleni salokho, isikhathi sesicelo esincane sewebhu ukuze sifinyelele kuseva ngayinye sibuye. Silandelela i-ping yangempela ye-ICMP eduze kakhulu futhi silungele ukuqhathanisa izindawo, nakuba lingafunda amamillisecond ambalwa aphezulu ngenxa yokuxhumana okuncane okwengeziwe. Thatha uhlelo lwendawo njengeqiniso elingaphikiswa nenombolo njengesilinganiso esiseduze kakhulu.
Yini ebalwa njenge-ping enhle?
Amabhande alinganiselwe, uhlobo abadlali nabashayi bezingcingo bengempela abaluzwayo:
- Ngaphansi kuka-30 ms — kuhle kakhulu; imidlalo yezibhamu yokuncintisana izwakala isheshe njengomshini.
- 30–50 ms — kuhle; kuyahamba kahle cishe kukho konke, akukho ukulibala okuzwakalayo.
- 50–100 ms — kulungile ukubhrawuza, ukusakaza kanye nokudlala okungajwayelekile.
- 100 ms nangaphezulu — uzokuzwa: ukubuyela emuva, ukushaya okulibele, isikhathi sokushaya izingcingo esingaqondile.
Ekushayeleni izingcingo zezwi nezevidiyo, ngaphansi kuka-50 ms kugcina ingxoxo ivamile; ngale kuka-150 ms abantu baqala ukukhulumisana ngesikhathi esisodwa.
Kungani i-latency inqoba i-bandwidth ezintweni ezenzeka ngesikhathi sangempela
Nasi into abantu abayenza ngokuphambene. I-Bandwidth yimuphi umfutho wedatha ongawuthutha ngasikhathi sinye, "isivinini" sakho ngama-megabit. I-Latency yisikhathi umlayezo omncane owodwa othatha sona ukufika khona nokubuya. Ekulandeni noma ukusakaza i-4K, i-bandwidth iyabusa. Kodwa emdlalweni wokuncintisana noma icingo eliphilayo, imilayezo mincane futhi ihlale ikhona, ngakho okubalulekile ukuthi ngamunye ufika ngokushesha kangakanani. Umgqa we-gigabit one-latency ephakeme uzoba nokulibala emdlalweni wezibhamu, kanti uxhumo oluncane olune-ping ephansi luzwakala luhlanzekile. Uma i-intanethi esheshayo isalibala emidlalweni, i-latency yiyo enecala, hhayi inombolo yakho yokulanda. Ungahlola isivinini semfutho sangempela ngokuhlukile nge-isilinganiso sesivinini.
Yini eyenza i-ping ikhuphuke
Abasolwa abajwayelekile abambalwa:
- Ibanga. Idatha ihamba ngokushesha kodwa hhayi ngokushesha ngokuphelele. Iseva ehlelweni olukude lomhlaba yengeza amamillisecond angempela ngoba ukukhanya kuthatha isikhathi ukuhamba ekhebulini.
- I-Wi-Fi. Ukungabi nazintambo kwengeza ukudideka nokulibala, ikakhulukazi i-2.4 GHz eminyene, izindonga ezicace, noma i-router ekwamagumbi amabili. Ikhebula ngokuvamile linciphisa isilinganiso esikhulu.
- Ukugcwala. Amanye amadivaysi ambambe umgqa, ukulanda okukhulu, noma ithrafikhi ye-ISP ngesikhathi esimatasa konke kwelula izikhathi zempendulo.
- Ukuqondiswa kwendlela. Amaphakethe awandizi ngomugqa oqondile. Aweqa ngama-router, futhi indlela ejikelezayo yengeza i-latency ngisho nedolobheni eliseduze, yingakho iseva "eseduze" kwesinye isikhathi i-ping kabi kunaleyo ekude.
Indlela ukuhlola komhlaba wonke kukusiza ukukhetha
Ngoba ukuqondiswa kwendlela akuqagelwa, indlela ende ethembekile yokuthola isifunda sakho esisheshayo kakhulu ukuyilinganisa. Sebenzisa isilinganiso futhi izinhla eziluhlaza eziseduze phezulu yizona zeseva okufanele uzikhethe ezemidlalo, izingcingo, noma noma yini enomthelela we-latency. Uma inkonzo ikuvumela ukukhetha isifunda sesikhungo sedatha, lena iwuphepha lwakho lokukhopha. Uyafuna ukwazi ukuthi uxhumo lwakho luvela kuphi? Hlanganisa lokhu ne-imininingwane ye-IP yakho.
Izindlela ezisebenzayo zokwehlisa i-ping yakho
- Sebenzisa ikhebula. Ikhebula le-Ethernet liwukunqoba okukhulu, olulula kakhulu, ngokuvamile lisusa ama-10–30 ms.
- Khetha iseva eseduze ngokusebenzisa isilinganiso somhlaba njengalesi esikhundleni sokuqagela.
- Vula umgqa. Misa ukulanda nokubuyekeza, uvale izinhlelo ezidla i-bandwidth ngasemuva.
- Qala kabusha i-router. Ingafinyelela kusiteshi se-Wi-Fi esihlanzekile futhi ikhiphe okuqoqiwe.
- Sebenzisa i-5 GHz uma kudingeka ungabi nezintambo, uhlale eduze ne-router ngezindonga ezimbalwa phakathi.
Akukho okudinga isofthiwe ekhethekile, futhi iningi lithatha umzuzu owodwa. Hlola, shintsha into eyodwa, uphinde uhlole, yindlela yangempela yokushintsha inombolo.
Imibuzo evame ukubuzwa
Yiziphi izinga elihle le-ping?
Ngaphansi kuka-50 ms kuhle cishe kukho konke, futhi ngaphansi kuka-30 ms kuhle kakhulu emidlalweni yokuncintisana. Ama-50 kuya ku-100 ms kulungile ekubhrawuzeni nasekusakazeni. Ngaphezu kuka-100 ms ngokuvamile uzokuzwa ukulibala emidlalweni esheshayo nasezingcingweni.
Ingabe i-ping iyafana ne-latency?
Ekusetshenzisweni kwansuku zonke, yebo. I-Latency ukulibala uqobo, kanti i-ping ithuluzi elikala lona. Inombolo yisikhathi sohambo lokuya nokubuya, isikhathi iphakethe elithatha sona ukufinyelela eseva libuye, ngamamillisecond.
Kungani i-ping yami iphakeme nangesikhathi sengingene ku-intanethi esheshayo?
I-Bandwidth ne-latency kuyahluka. Ungaba nokulanda okusheshayo kodwa ube ne-ping ephezulu ngenxa yebanga eliya eseva, ukuphazamiseka kwe-Wi-Fi, ukugcwala kwenethiwekhi, noma indlela yokuqondisa engalungile. Ezintweni zesikhathi sangempela, i-latency ibaluleke kakhulu kunesivinini esiluhlaza.
Ingabe lolu hlolo lwebhrawuza luyahambisana nomyalo we-ping?
Kuseduze kakhulu. Umyalo weqiniso we-ping usebenzisa i-ICMP, engeke ithunyelwe ababhrawuza, ngakho leli thuluzi lilinganisa uhambo lokuya nokubuya lwe-HTTP esikhundleni salokho. Lilandelela i-ping ye-ICMP eduze kakhulu kodwa lingafunda amamillisecond ambalwa aphezulu, futhi liyathembeka ekuqhathaniseni izindawo.
Ngingayehlisa kanjani i-ping yami?
Sebenzisa i-Ethernet enezintambo esikhundleni se-Wi-Fi, khetha iseva eseduze, misa ukulanda ngasemuva, qala kabusha i-router yakho, futhi ukhethe i-5 GHz Wi-Fi uma ungakwazi ukusebenzisa izintambo. Ukushintshela kuphela ku-Ethernet ngokuvamile kususa ama-10 kuya ku-30 ms.
Yiziphi izinga elihle le-ping ezemidlalweni ku-inthanethi?
Emidlalweni yezibhamu yokuncintisana nokujaha, hlose ngaphansi kuka-20 kuya ku-30 ms. Ngaphansi kuka-50 ms kuzwakala kuhlanzekile emidlalweni eminingi. Imidlalo yamasu neyokulinda kungadlaleka kahle kuze kube ngaphansi kuka-100 kuya ku-150 ms, kodwa ephansi ihlale ingcono.
