Kodi DCI Box ndi chiyani

Chiyambi cha netiweki ya DCI

 Pachiyambi, malo osungiramo deta anali ophweka, okhala ndi makabati + ochepa apamwamba a P air conditioners m'chipinda chopanda pake, ndiyeno mphamvu imodzi yamzinda wamba + UPS yochepa, ndipo inakhala malo opangira deta.Komabe, mtundu uwu wa data center ndi wochepa kwambiri komanso wodalirika.Intaneti, yomwe yakhala ikukula mopenga kuyambira kumapeto kwa zaka za m'ma 1990, yawonjezeranso kufunikira kwa malo opangira deta.Choncho, pali vuto losasinthika mumtundu uwu wa data: malo osakwanira , Mphamvu zopanda mphamvu, zopanda ntchito, komanso palibe chitsimikizo cha SLA, zomwe zimapangitsa kuti ogwiritsa ntchito ayambe kupeza malo ena opangira malonda.Panthawi imeneyi, deta latsopano likulu ndi deta yakale likulu anayamba kukhala zofunika maukonde interconnection, chifukwa choyamba DCI maukonde, ndiye Data Center Inter-kugwirizana, zomwe zikuphatikizapo umisiri pa mlingo maukonde thupi ndi zomveka Intaneti mlingo.

 Network yoyamba ya DCI idalumikizidwa mwachindunji kudzera pa intaneti.Pambuyo pake, poganizira za chitetezo, kusungidwa kunagwiritsidwa ntchito, ubwino wa utumiki unaganiziridwa, mizere yodzipatulira inagwiritsidwa ntchito, ndipo bandwidth inalumikizidwa mwachindunji ndi fiber optical.

Kukula kwa netiweki ya DCI

Kukula kwa ma netiweki a DCI kuchokera ku kulumikizana kwa intaneti, kupita ku mizere ingapo yodzipatulira ya M, mpaka kulumikizano kwapawiri kwa 10T WDM sinthawi yayitali, molunjika, ndikuyankha pakukula kwa intaneti.Poyambirira, ogwiritsa ntchito amagwiritsa ntchito njira yapagulu ya VPN kuti atumize mautumiki awo mwachindunji kudzera pa intaneti.Njirayi imakhudzidwa ndi malo osiyanasiyana amtundu wa anthu (kuchulukana kwapadziko lonse lapansi kwa bandwidth, kutsika kwapansi, jitter line, reset reset, firewall, etc.) Chifukwa cha mtengo ndi mtengo, ndi yoyenera kwa magalimoto ang'onoang'ono, zofunikira zochepa zamtundu wa bandwidth, osati -nthawi yeniyeni, komanso zofunikira zochepa zachitetezo.Pambuyo pake, bizinesi mu data center inakopeka kwambiri, ndipo bizinesi inayamba kuwonjezereka pang'onopang'ono, ndipo chiwerengero cha ma seva chinawonjezeka motsatira..Pambuyo pa ntchito zambiri zomwe zimagwiritsidwa ntchito, mautumikiwa omwe amafalitsidwa kudzera pa intaneti ali ndi zotsatira zowonjezereka kwa makampani ndi mafakitale, kotero kuti zofunikira pa intaneti zikukhalanso zapamwamba, zoyamba zikuwonekera mu bandwidth ndi kukhazikika kwa chiyanjano, kotero ogwiritsira ntchito deta amayamba kupita ku mizere yodzipereka yoperekedwa kwa oyendetsa, MSTP mizere yoperekedwa pa netiweki ya SDH yayamba kugulitsa bwino chifukwa cha kukhazikika kwawo, bandwidth yayikulu, komanso kuchuluka kwa kuchuluka kwa opareshoni.

Pambuyo pake, ndi kukula kosalekeza kwa bizinesi, deta pakati pa malo opangira deta inayamba kukhala ndi zofunikira zochepetsera ndi kuchotsedwa ntchito, makamaka kwa makasitomala a zachuma, omwe anali ndi zofunikira kwambiri kuti achedwe, kotero kuti zofunikira za mizere yodzipereka zinalinso.

kuchuluka;Kapena, ogwiritsa ntchito amayamba kufuna granularity yayikulu, monga 2.5G, 10G single-link bandwidth, komanso amafuna chitetezo chapawiri kuti atsimikizire kuti LSA ikufika ku 4 mpaka 5 9s.

 Ngakhale zili choncho, mphamvu ya chitukuko cha intaneti ndi yodabwitsa, ndipo machitidwe amalonda monga kutumizira logi ndi kugwirizanitsa deta akukula.Poganizira za mtengo, nthawi yobweretsera, khalidwe lautumiki, ndi zina zotero, makampani apamwamba (makamaka makampani a intaneti omwe ali ndi deta yaikulu monga Google ndi FB) ayamba kupanga ma network a DCI pobwereka ma fiber optical opanda ogwira ntchito.Kumayambiriro kwa kugwiritsa ntchito bare optical fiber, inalinso njira yoyendetsera chizindikiro chimodzi kudzera mumtundu umodzi wa kuwala.Mwachitsanzo, ma fiber optical amatha kugwiritsa ntchito gawo la 10G ZR kufalitsa mtunda wa makilomita 80.zokwanira.Komabe, kuipa kwa njirayi ndikuti kumbali imodzi, kuchuluka kwa ma fiber optical kumawonjezeka motsatira bandwidth, ndipo mtengo ukuwonjezeka;Vuto lalitali komanso lovuta), ndipo panthawiyi, bandwidth ya 10G ya fiber imodzi silingathe kukwaniritsa zosowa za kukula kwa bizinesi, kotero kuti intaneti ya DCI inayamba nthawi ya WDM.

Munthawi ya WDM, njira ziwiri zidawonekera mu netiweki ya DCI, ndiko kuti, gawo lozungulira la CWDM ndi division dense wavelength DWDM.Malingana ndi kulingalira kwa mtengo, ena ogwiritsa ntchito oyambirira adagwiritsa ntchito 10G CWDM optical modules kwa DCI interconnection pogwiritsa ntchito teknoloji ya CWDM.Komabe, dongosololi limathandizira mpaka mafunde a 16 a 10G, ndipo EDFA sangathe kukulitsa chizindikiro pamtunda wa CWDM., ndipo mtunda wake wongopatsirana nawonso ndi wochepa.Choncho, pamene kufunikira kwa kufalitsa deta kwakukulu kukupitirirabe, ogwiritsa ntchito ayenera kuyamba kugwiritsa ntchito machitidwe a DWDM omwe ali ndi mphamvu zapamwamba komanso ntchito.
