Thaum lub network hloov interface tau txais kev khiav tsheb ntau dua li nws tuaj yeem ua tau, lub network hloov yuav xaiv rau qhov tsis muaj nws, lossis lub network hloov pauv yuav poob nws.
Lub cache ntawm lub network hloov feem ntau yog tshwm sim los ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm lub network, kev sib tsoo ntawm cov tsheb khiav ntawm lub network hloov lossis ntau-rau-ib kis.
Qhov teeb meem tshwm sim ntau tshaj plaws uas ua rau muaj kev tsis sib haum xeeb hauv 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 thov cov ntaub ntawv los ntawm lub network keyboards ntawm tag nrho lwm cov ntawm tib lub sijhawm, tag nrho cov lus teb yuav tsum tuaj txog ntawm lub network keyboards tib lub sijhawm. Thaum qhov no tshwm sim, kev khiav dej nyab los ntawm txhua lub network hloov mus rau qhov chaw nres nkoj ntawm tus neeg thov lub network hloov. Yog hais tias lub network hloov tsis muaj egress buffers txaus, lub network hloov tej zaum yuav poob ib co tsheb khiav, los yog lub network hloov tsub kom daim ntawv thov latency. Kev hloov pauv hauv lub network txaus tuaj yeem tiv thaiv pob ntawv poob lossis cuam tshuam hauv lub network uas tshwm sim los ntawm 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 hloov cache ntawm network keyboards. Network keyboards muaj ib lub pas dej ntawm qhov chaw tsis tau faib rau cov chaw nres nkoj tshwj xeeb. Network hloov pauv hloov cache 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, uas 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 tau, network keyboards tsis tas yuav buffers ntawm qib hloov.
Qhov tsis ntawm lub network hloov pauv tseem ceeb heev, tab sis tsis muaj lus teb kom raug 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 network hloov latency - cov ntaub ntawv uas yuav tsum tau tos ua ntej xa mus los ntawm lub network hloov. Qee tus thawj tswj hwm hauv lub network nyiam me dua network hloov buffers, cia daim ntawv thov lossis cov txheej txheem tswj qee qhov kev khiav tsheb. 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.
