Nrog kev tawm tsam ntawm thev naus laus zis hauv kev sib txuas lus, kev ceev nrawm ntawm cov ntaub ntawv hloov chaw tau mus txog qib tshiab. Cov kab hluav taws xob fiber ntau muaj peev xwm muab cov ntaub ntawv hloov mus los tau. Nws feem ntau hloov tawm tias qhov kev kub ceev tsis ncaj thiab raug nqi nyiaj ntxiv. Nws yog ib qho tseem ceeb kom tsis txhob poob rau kev lag luam ntawm cov muab kev pab thiab txiav txim siab qhov koj xav tau.
Txhawm rau kom nkag mus rau hauv txhua lub nuances thaum xaiv tus nqi them nyiaj rau Is Taws Nem, koj yuav tsum paub ob peb qhov tseeb txog cov qauv ntawm lub network, uas yuav pab koj siv cov kev pab cuam zoo dua.
1 Mbps yog li 8 zaug ntau dua 1 Mbps. Nws hloov tawm tias muaj qhov Internet ceev ntawm 8 Mbps, peb tau txais qhov nrawm ntawm kwv yees li 1 Mbps. Kev rub suab paj nruag 5 MB yuav muab rub ua (lossis rub tawm kiag) hauv 5 vib nas this. Yog li, paub txog koj cov kev xav tau hauv lub network, koj tuaj yeem suav lub sijhawm nws yuav siv los ua kom tiav qhov haujlwm lossis qhov haujlwm ntawd ntawm tus nqi tam sim no.
Nws qhov ua tau zoo tau cuam tshuam los ntawm cov tseem ceeb tshaj plaws, piv txwv li cov cuab yeej siv network, kev nrawm ntawm cov chaw taws teeb, qhov theem ntawm lub teeb liab wireless, kev ceev ntawm lub cuab yeej kawg, thiab lwm yam. Yog tias koj tus neeg zov me nyuam txaus siab tshaj 50 megabits ib pliag, tom qab ntawd saib cov yeeb yaj kiab online, tej zaum koj yuav tsis tau txais qhov nrawm ntawd, vim tias lub khoos phis tawj nrog cov yeeb yaj kiab yog nyob deb. Cov neeg rau zaub mov tau xa nrog cov khoom faib tawm ntawm cov yeeb yaj kiab no mus rau ntau txhiab, lossis ntau txhiab tus neeg siv ntau tus.
Qhov no yog qhov sib piv rau cov yeeb nkab dav uas los ntawm ib tus kwj me ntws: qhov chaw (server) tsis muaj peev xwm muab tau, thiab txhua qhov chaw ntxiv yog qhov khoob. Qhov xwm txheej zoo li no tshwm sim yog tias koj nrog lub ntsiav tshuaj hla 2 phab ntsa thiab txheej txheej ntawm rooj tog los ntawm lub router - qhov ceev ntawm Wi-nkaus channel yuav poob, thiab tsis muaj teeb meem li cas sai hauv Is Taws Nem tuaj txog koj lub tsev, nws yuav mus txog lub cuab yeej ntawm lwm qhov, qis dua nrawm.
Qhov tseeb ping yog qhov ceev ntawm kev nkag mus rau cov ntaub ntawv hauv Is Taws Nem, i.e. sai npaum li cas qhov kev thov mus. Yog tias thaum qhov siab ceev lub ping yog loj, ces yuav muaj kev xyaum tsis muaj kev nkag siab los ntawm nws: kev thov yuav qeeb. Loj ping muaj qhov tshwj xeeb tsis zoo rau kev saib xyuas lub web zoo sib xws, qhov twg txhua tus nias nas yog qhov kev thov, ntxiv rau hauv online ua si, qhov twg synchronization dab tsi tshwm sim hauv lub sijhawm tiag yog nyob ntawm ping.
… Yog tias txhua yam tsis tseem ceeb nrog cov nkauj, tk. Txij li thaum qhov ntau thiab tsawg ntawm cov nkauj muaj tsawg, tom qab ntawd nrog cov vis dis aus koj yuav tsum tau saib xyuas zoo rau qhov zoo hauv koj saib nws. Qhov siab dua qhov zoo, qeeb qeeb ntawm kev tiv thaiv (thau khoom) ntawm cov yeeb yaj kiab lossis cov yeeb yaj kiab duab. Piv txwv li, 480p zoo yuav tsum tau yuav luag ib nrab ntawm qhov nrawm piv rau 1080, txawm hais tias ntau lub koob npe nrov tau txiav txim siab ua video zoo, yog li cov teeb meem tau dhau los ua tsawg dua.
Ntawm no cov khoos phis tawj ntawm cov neeg siv ua lub vev xaib, thiab cov ntaub ntawv ceev nrawm hloov mus rau koj lub khoos phis tawm rau tag nrho cov servers. Yog li ntawd, tag nrho cov upload ceev tuaj yeem yog qhov siab heev, muaj peev xwm thauj khoom txhua qhov Internet channel.
Xav txog txhua yam no, cov lus qhia hauv qab no tuaj yeem ua.
- txog 5 Mbps yuav ntau dua rau kev nkag hauv lub vev xaib thiab mloog cov nkauj tib lub sijhawm, thiab Internet channel muaj peev xwm sib faib ntau yam khoom siv nrog cov haujlwm no
- 10 Mbps tuaj yeem ua kom tsis muaj qhov cuam tshuam ntawm FullHD video ntawm 2 pab kiag li lawm, thiab ntawm tus thib peb koj tuaj yeem yooj yim mus xauj hauv nplooj ntawv
- 20 Mbps yog qhov xwm ceev uas yuav ua rau koj saib FullHD zaj yeeb yaj kiab nrog kev rub tawm torrent tib txhij, thiab koj tseem tuaj yeem nyab xeeb dai koj lub xov tooj nrog lub ntsiav tshuaj ntawm cov channel thiab saib Youtube yooj yim. Rau kev teb thiab web surfing, qhov ceev yog ntau dhau.
- 40 mbps. Cov routers qub tsuas tsis txhawb nqa qhov nrawm no. Tsis tas yuav hais, 40 Mbps yog txaus rau txhua yam. Nws tuaj yeem pom zoo rau cov neeg siv nrog cov haujlwm tshwj xeeb, xws li FTP server lossis ua haujlwm nrog cov ntaub ntawv hauv huab tshuab.

- 60 Mbps thiab saum toj no. Yog lawm, tam sim no qee tus kws kho mob muaj cov lej zoo li no, thiab lawv xav tau tsawg heev. Nws tshwm sim hais tias tus kws kho mob cog lus tias txawm 100 Mbps thiab siab dua thaum hmo ntuj, tab sis kom tswj tau qhov kev nrawm no koj xav tau cov khoom muaj zog uas kim dua thiab cov "gigabit" cables. Yuav luag txhua lub xov tooj ntawm tes yuav qhib tsis tau ntawm lub nrawm no, thiab lub khoos phis tawj xav tau leej niam kim heev uas muaj 1000mb network card, lossis gigabit network card.
Ua rau hauv qhov nruab nrab qhov xav tau nruab nrab ntawm cov neeg siv Is Taws Nem, nyob rau hauv cov kev mob niaj hnub no, ib qho Internet ceev ntawm 15-20 Mbps yog txaus rau yuav luag txhua txoj haujlwm.

Tab sis cov chaw muab kev pab paub zoo heev tias tsuas yog ib lub hlis twg ntawm tib 60 Mbps yuav siv, yog li qhov tseeb lawv xa tawm 15-20 Mbps rau tus nqi ntawm 60. Feem ntau, qhov sib txawv tau hnov tsuas yog thaum ua haujlwm nrog torrent cov neeg, tab sis rau feem ntau cov neeg siv nws yog kog tsis muaj nqi tshaj cov nyiaj them tshaj.
