Lub network hloov yog ib qho cuab yeej uas nthuav dav lub network thiab tuaj yeem muab cov chaw nres nkoj sib txuas ntau dua hauv sub-network los txuas ntau lub khoos phis tawj.Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ua haujlwm siab, kev sib txheeb yooj yim, thiab kev siv tau yooj yim.

Thaum lub network hloov interface tau txais kev khiav ntau dua li nws tuaj yeem ua tau, lub network hloov pauv xaiv rau cache nws lossis lub network hloov mus tso nws.Buffering ntawm network keyboards feem ntau yog tshwm sim los ntawm qhov sib txawv network interface tus nqi, tam sim ntawd tawg ntawm kev khiav tsheb ntawm lub network keyboards lossis ntau-rau-ib qho kev sib kis.

Qhov teeb meem tshwm sim ntau tshaj plaws uas ua rau muaj kev tsis sib haum xeeb ntawm kev hloov pauv hauv lub network yog kev hloov pauv sai ntawm ntau-rau-ib lub tsheb.Piv txwv li, ib daim ntawv thov yog tsim los ntawm ntau lub server pawg nodes.Yog tias ib qho ntawm cov nodes ib txhij thov cov ntaub ntawv los ntawm lub network keyboards ntawm tag nrho lwm cov nodes, tag nrho cov lus teb yuav tsum tuaj txog ntawm lub network keyboards tib lub sijhawm.Thaum qhov no tshwm sim, txhua lub network hloov dej nyab cov chaw nres nkoj ntawm tus neeg xa khoom lub network hloov.Yog hais tias lub network hloov tsis muaj egress buffers txaus, lub network hloov yuav poob ib co tsheb khiav, los yog lub network hloov yuav ua rau kom daim ntawv thov latency.Lub network hloov pauv txaus tuaj yeem tiv thaiv pob ntawv poob lossis lub network latency vim muaj cov txheej txheem qis.

Feem ntau niaj hnub cov ntaub ntawv chaw hloov pauv platforms daws qhov teeb meem no los ntawm kev sib koom qhov hloov pauv cache ntawm lub network keyboards.Network keyboards muaj qhov chaw tsis muaj chaw faib rau cov chaw nres nkoj tshwj xeeb.Network keyboards qhia hloov pauv caches uas sib txawv ntawm cov neeg muag khoom thiab cov platforms.

Qee lub network hloov chaw muag khoom muag cov hloov pauv network tsim los rau ib puag ncig tshwj xeeb.Piv txwv li, qee lub network keyboards muaj kev ua haujlwm tsis zoo thiab tsim nyog rau Hadoop ib puag ncig hauv ntau-rau-ib kis xwm txheej.Network keyboards Nyob rau hauv ib puag ncig uas muaj peev xwm faib tsheb khiav, network keyboards tsis tas yuav siv buffers ntawm qib hloov.

Network hloov buffers yog qhov tseem ceeb heev, tab sis tsis muaj lus teb rau qhov chaw hloov pauv network ntau npaum li cas peb xav tau.Loj loj network hloov buffers txhais tau hais tias lub network tsis poob ib qho kev khiav tsheb, tab sis nws kuj txhais tau hais tias muaj zog hloov network latency - cov ntaub ntawv uas khaws cia los ntawm lub network hloov yuav tsum tau tos ua ntej xa mus.Qee tus thawj tswj hwm hauv lub network nyiam cov buffers me me ntawm cov hloov pauv hauv lub network kom cia daim ntawv thov lossis cov txheej txheem tswj qee cov tsheb khiav.Cov lus teb raug yog kom nkag siab txog cov qauv tsheb khiav ntawm koj daim ntawv thov lub network keyboards thiab xaiv lub network hloov uas haum rau cov kev xav tau.
