Kwakabva DCI network

 Pakutanga, nzvimbo yedata yakanga iri nyore, ine makabati mashoma + mashoma epamusoro-P air conditioners mune imwe nzvimbo isina kujairika, uyezve imwe yakajairika simba reguta + mashoma UPS, uye yakava nzvimbo yedata.Nekudaro, iyi mhando yedata data idiki pachiyero uye yakaderera mukuvimbika.IInternet, iyo yanga ichikura nekupenga kubva pakupera kwema1990, yakawedzerawo kudiwa kwenzvimbo dzedata.Nokudaro, pane dambudziko risingagadziriswi mumhando iyi yedata data: nzvimbo isina kukwana , Simba risina kukwana, hapana redundancy, uye hapana SLA vimbiso, zvichiita kuti vashandisi vatange kutsvaga imwe nzvimbo yedata yekutengeserana kwebhizimisi.Panguva ino, nzvimbo itsva yedata uye nzvimbo yekare yedata yakatanga kuva nemambure interconnection zvinodiwa, zvichiita kuti pave nekutanga DCI network, kureva, Data Center Inter-connect, iyo inosanganisira michina pahutano hwemambure emuviri uye inonzwisisika network level.

 Iyo yekutanga DCI network yakabatana zvakananga kuburikidza neInternet.Gare gare, mukufungisisa nezvekuchengetedzwa, encryption yakashandiswa, hutano hwebasa hwaifungidzirwa, mitsetse yakatsaurirwa yakashandiswa, uye bandwidth yakanyatsobatanidzwa ne optical fiber.

Kuvandudzwa kweDCI network

Kuvandudzwa kweDCI network kubva paInternet interconnection, kune akati wandei M mitsara yakatsaurirwa, kune yazvino multi-10T WDM yekubatanidza haisi nguva yakareba, zvine chinangwa, imhinduro kukuvandudzwa kweInternet.Pakutanga, vashandisi vanoshandisa iyo yeruzhinji network VPN mugero kufambisa masevhisi avo zvakananga kuburikidza neruzhinji network.Iyi nzira inokonzerwa nemamiriro akasiyana-siyana ehutano hweveruzhinji (global network bandwidth congestion, yakaderera routing, line jitter, link reset, firewall, etc.) Inokonzerwa nemutengo uye mari, inokodzera kudiki traffic, low bandwidth quality zvinodiwa, kwete. -chaiyo-nguva, uye yakaderera kuchengetedzwa zvinodiwa.Gare gare, bhizinesi riri munzvimbo yedata rakakwezva kutarisisa kwakawanda, uye bhizinesi rakatanga kuwedzera zvishoma nezvishoma kutumirwa, uye nhamba yemaseva yakawedzera mutsara..Mushure mekunge nhamba huru yemasevhisi aiswa, masevhisi aya anofambiswa kuburikidza netiweki ane simba rinowedzera kumakambani nemaindasitiri, saka izvo zvinodikanwa zvetiweki zviri kuwedzera uye zvakanyanya, zvinotanga kuratidzwa mubandwidth uye kugadzikana kwekubatanidza, saka vashandisi ve data data vanotanga. kuLeased opareta wedunhu mitsara yakatsaurirwa, MSTP mitsetse yakatsaurirwa inotakurwa paSDH network yatanga kutengesa zvakanaka nekuda kwekugadzikana kwavo kwepamusoro, bandwidth yakakura, uye dhigirii repamusoro remushandisi kuwanda.

Gare gare, nekuenderera mberi kwekusimudzira kwebhizinesi, iyo data pakati penzvimbo dzedata yakatanga kuva nezvinodiwa zvekunonoka uye kuderedzwa, kunyanya kune vatengi vezvemari, avo vaive nezvinodiwa zvakanyanya zvekunonoka, saka izvo zvinodiwa zvemitsara yakatsaurirwa zvaive zvakare.

kuwedzera;Kana kuti, vashandisi vanotanga kuda granularity yakakura, yakadai se 2.5G, 10G single-link bandwidth, uye inodawo kuchengetedzwa kwemaviri-nzira kuitira kuti LSA isvike 4 kusvika 5 9s.

 Kunyange zvakadaro, simba rekuvandudzwa kweInternet rinoshamisa, uye maitiro emabhizimisi akadai sekutumira log uye kuwirirana kwedatabase ari kukura.Tichifunga nezvemutengo, nguva yekuendesa, kunaka kwesevhisi, nezvimwewo, makambani epamusoro (kunyanya makambani eInternet ane data hombe seGoogle neFB) atanga kuvaka DCI network nekuhaya bare optical fibers pasina vashandisi.Pakutanga kwekushandisa bare optical fiber, yaivewo nzira yekumhanyisa chiratidzo chimwe chete kuburikidza neimwechete optical fiber.Semuenzaniso, peya yemafiber optical inogona kushandisa 10G ZR module kuendesa 80 makiromita kure.zvakakwana.Zvisinei, kukanganisa kweiyi nzira ndeyokuti kune rumwe rutivi, kuwanda kwekushandiswa kwefiber optical kunowedzera mutsara ne bandwidth, uye mari inowedzera;Dambudziko renguva refu uye rakaoma), uye panguva ino, 10G bandwidth yefiber imwe chete haigoni kusangana nezvinodiwa zvekukura kwebhizimisi, saka network yeDCI yakatanga nguva yeWDM.

Munguva yeWDM, nzira mbiri dzakaonekwa muDCI network, kureva, coarse wavelength division CWDM uye dense wavelength division DWDM.Kubva pakufunga kwemitengo, vamwe vashandisi vekutanga vakashandisa 10G CWDM optical modules yeDCI yekubatanidza vachishandisa tekinoroji yeCWDM.Nekudaro, iyi sisitimu inotsigira kusvika ku16 mafungu e10G, uye EDFA haigone kukwidziridza chiratidzo pawavelength yeCWDM., uye chinhambwe chayo chekutenderedza chinhambwe zvakare chakaganhurirwa.Nokudaro, sezvo kudiwa kwehuwandu hwemashoko makuru huri kuramba huchikwira, vashandisi vanofanira kutanga kushandisa DWDM masisitimu ane huwandu hwepamusoro uye kushanda.
