Cov kws kos duab kos duab, kev xaiv tsim, thiab cov thev naus laus zis sci niaj hnub infrastructure
Qhov tshwm sim ntawm loj - teev cov chaw zov me nyuam muaj tswv yim hloov kho peb txoj kev txuas lus ntxiv. Raws li cov koom haum ua kom muaj kev cia siab rau cov chaw siv hluav taws xob, cov koom haum DCI tau dhau los ua kev sib txuas ntawm thaj chaw sib txuas ntawm thaj chaw. Nkag siab txog cov kws kos duab kos thiab kev tsim qauv thiab cov kev txiav txim siab rau cov tes hauj lwm no yog qhov tseem ceeb rau kev ua kom lub tsev muaj zog.
"DCI network pabcuam ua cov haujlwm sib koom ua haujlwm raws li kev sib koom ua ke, txuas cov chaw sib koom ua ke cov ntaub ntawv thaum tswj hwm kev ua tau zoo thiab kev ntseeg tau."
Thawj qhov lus nug tseem ceeb hauv kev tsim cov ntaub ntawv chaw sib koom tes txhawj xeeb lub hom phiaj ntawm kev ua haujlwm. Thaum kev lag luam ntawm cov nplai qhia tau tias cov chaw loj me me muab cov nqi ntau dua, cov kev txwv zoo xws li muaj lub zog muaj kev txwv tiag tiag. Tsis tas li ntawd, kom ntseeg tau kev txhaum rau kev ua txhaum thiab tswj qis rau cov neeg siv thoob ntiaj teb, cov chaw muab cov ntaub ntawv yuav tsum tau faib rau hauv ntau thaj chaw thaj chaw. Qhov kev txhawb nqa no ua rau DCI network architecture ntxiv qhov tseem ceeb tshaj plaws rau kev tswj cov haujlwm sib koom ua haujlwm thoob plaws cov chaw.
Qhov kev txiav txim siab thib ob tseem ceeb cuam tshuam nrog kev txiav txim siab tag nrho cov kev ntsuas muaj peev xwm thiab kev sib txuas lus bandwidth yuav tsum tau los ntawm cov ntawv thov phiaj. Kev sib tham nrog cov platform ua piv txwv txog qhov kev sib tw no, raws li lawv yuav tsum tau khaws thiab rov ua dua txhua tus neeg siv-} greated cov ntsiab lus thoob plaws pawg neeg. Cov kev txhawb nqa network infrastrastrastrasure yog qhov kev thov sab nraud yuav tsum sib txuas rau ntau pua lossis txawm tias muaj cov servers ua kom tiav. Nyob rau hauv cov ntsiab lus no, DCI network pab raws li tus qaum teb txhawb cov kev ua haujlwm faib tau ua haujlwm raws li kev sib koom ua ke.
Qhov lus nug tseem ceeb thib peb cov kev kawm ntawv uas cov servers uas muaj peev xwm muab tau ntau yam kev siv thiab khoom. Cov vev xaib Portal zoo li Yahoo, tuaj yeem tuav ntau pua tus neeg siv khoom siv sib txuas lus nrog cov ntaub ntawv hauv cov ntaub ntawv ua ke, cov khoom tshaj tawm, thiab kev lag luam lag luam. Qhov hloov tau yooj yim los ntawm DCI network niaj hnub siv tso cai rau kev ua haujlwm tau muab cov nyiaj pab ntau thoob plaws cov chaw ua haujlwm sib txawv no.
Tsoos nplai -} wb network architecture
Daim duab 2.1 Qhia txog cov ntaub ntawv raug cov ntaub ntawv Network architecture siv cov nplai ib txwm - up mus kom ze. Nyob rau hauv qhov kev teeb tsa no, txhua rabd muaj cov tshuab uas cov servers sib txuas nrog rau saum - khib (tor) hloov ntawm tooj liab cable los yog kho qhov muag. Cov tor hloov mus tom qab txuas rau kev nkag tau txheej txheej hloov mus los ntawm kev hloov kho kho qhov muag. Thaum txhua tus Tor hloov ua haujlwm u uplinks, tag nrho cov network tuaj yeem txhawb nqa koj nkag mus rau hauv ib pawg, uas yog TAN hloov pauv hauv parallel rau ntau yam khawm. Qhov chaw nres nkoj suav C ntawm txhua qhov nkag mus txiav txim tag nrho cov naj npawb ntawm lub tor txhawb nqa.
Yog tias txhua lub Tor hloov siv d downlinks txuas rau txhua pawg no tuaj yeem nthuav mus rau c × d piv ntawm D: C ntawm Tor txheej. Thaum no ob {-}}}}}}}}} Feem ntau cov khaubncaws sab nraud povtseg ntxiv rau txheej txheem kev sib sau ua ke. Qhov kev nthuav dav no los ntawm tus nqi ntawm ntau dua latency thiab ntau dua sab hauv kev sib tw txuas ntxiv rau network. Txhawm rau txhawm rau ntau pawg, peb {{-}}}}}}}}}}}}}} Tier cluster routers (CR) tau siv rau saum cov ntaub ntawv chaw npuag.
Nyob rau hauv ib qho xwm txheej zoo tshaj plaws, tag nrho - mesh network qauv txuas ncaj qha rau cov ntaub ntawv ntawm cov ntaub ntawv txuas ntxiv thaum ua kom yooj yim lub cajmeem thiab txhim kho cov neeg ua haujlwm server txuas tau zoo. Txawm li cas los xij, cov qauv kev tsim qauv no tsis tshua kim, yuav tsum tau siv daim ntawv thov ntawm kev sib txuas ntawm txhua txheej. Thaum twg tsis tuaj yeem pab txhawb bandwidth xav tau, cov koom haum kev coj ua tshiab yuav khoom muaj zog dua los tsim cov khoom loj dua {} Cov nplai- up mus kom ze. Qhov kev paub no, thaum tsim nyog rau me me rau nruab nrab- qhov chaw nqis peev, yuav tsum ntseeg tau ntau yam, muaj kev ntseeg siab, siab} lub peev xwm kho vajtse.
Qhov tshwm sim ntawm cov nplai - tawm DCI network qauv
Tshaj li kaum xyoo dhau los, kev txhim kho ntawm cov khoom lag luam silicon hloov cov chips thiab software {{{{{{Control cov dav hlau tau tswj hwm cov ntaub ntawv chaw kos duab kos duab. Cov nplai - tawm qauv tau superseded lub nplai {}} teev xam thiab lub platform. Qhov kev hloov pauv no tau ua tshwj xeeb tshaj plaws hauv kev hloov kho ntawm DCI network tsim, ua rau cov ntsuas ntsuas ntsuas thiab yoog raws.
Daim duab 2.2 Ua kom pom cov nplai - tawm cov ntaub ntawv chaw architecture uas tau dhau los ua tus qauv kev lag luam. Txhawm rau tsim loj- nplai, tsis {4 4}} blocking ntawm cov hloov tshiab network, Cov txheej txheem nkag mus tuaj yeem muaj cov tsoos Tor hloov ua haujlwm ua tiav txheej 2 hloov cov haujlwm lossis pob tshab ntawm cov neeg rau zaub mov txuas nrog. Lub network muab tag nrho cov bisectional bandwidth nrog cov kev sib txawv ntawm kev sib tw hauv kev sib txuam hauv thiab nruab nrab.
Cov nplai - tawm DCI network qauv coj ntau qhov zoo rau cov khoom loj rau cov ntaub ntawv loj:
