Kwakatangira network yeDCI

 Pakutanga, nzvimbo yedata yaive yakapfava, ine makabati mashoma + maair conditioner mashoma ane ma high-P mukamuri rakasarudzika, uye ipapo simba rimwe chete reguta + maUPS mashoma, uye yakava nzvimbo yedata. Zvisinei, rudzi urwu rwenzvimbo yedata idiki uye haina kuvimbika. Indaneti, yave ichikura zvakanyanya kubva kumagumo kwema1990, yakawedzerawo kudiwa kwenzvimbo dzedata. Nokudaro, pane dambudziko risingagadzirisike mumhando iyi yenzvimbo yedata: nzvimbo isina kukwana, Kusakwana kwemagetsi, kusawedzerwa kwemagetsi, uye kusave nevimbiso yeSLA, zvichiita kuti vashandisi vatange kutsvaga imwe nzvimbo yedata yekushandisa bhizinesi. Panguva ino, nzvimbo itsva yedata nenzvimbo yekare yedata zvakatanga kuva nezvinodiwa zvekubatanidza network, zvichikonzera network yekutanga yeDCI, kureva, Data Center Inter-connect, inosanganisira matekinoroji padanho re network remuviri uye logical network level.

 Network yekutanga yeDCI yakabatana zvakananga kuburikidza neInternet. Gare gare, mukufunga nezvekuchengetedzwa, encryption yakashandiswa, mhando yebasa yakafungwa, mitsetse yakatsaurirwa yakashandiswa, uye bandwidth yakabatana zvakananga ne optical fiber.

Kugadzirwa kwenetwork yeDCI

Kugadzirwa kwema network eDCI kubva pakubatanidza ma internet, kusvika pamitsetse yakati wandei yakatsaurirwa M, kusvika pakubatanidza ma multi-10T WDM kuripo hakusi kwenguva refu, asi zviri pachena, imhinduro kukuvandudzwa kwe internet. Pakutanga, vashandisi vanoshandisa public network VPN tunnel kutumira masevhisi avo zvakananga kuburikidza ne public network. Nzira iyi inokanganiswa nenzvimbo dzakasiyana dze public network (global network bandwidth congestion, inferior routing, line jitter, link reset, firewall, nezvimwewo). Ichikanganiswa nemutengo nemutengo, yakakodzera traffic diki, low bandwidth quality requirements, non-real-time, uye low security requirements. Gare gare, bhizinesi riri mu data center rakakwezva kutariswa kwakawanda, uye bhizinesi rakatanga kuwedzera zvishoma nezvishoma deployment, uye nhamba yema servers yakawedzera linearly. Mushure mekunge masevhisi akawanda aendeswa, masevhisi aya anotumirwa kuburikidza nenetwork ane simba rinowedzera pamakambani nemaindasitiri, saka zvinodiwa nenetwork zviri kuramba zvichikwira, zvichitanga kuratidzwa mukugadzikana kwebandwidth uye link, saka vashandisi vedata center vanotanga kuLeased operator circuit dedicated lines, MSTP dedicated lines dzinotakurwa paSDH network dzatanga kutengeswa zvakanaka nekuda kwekugadzikana kwadzo kwakanyanya, bandwidth yakakura, uye mwero wepamusoro we operator multiplexing.

Gare gare, nekukura kuri kuramba kuchiitika kwebhizinesi, data pakati penzvimbo dzedata rakatanga kuva nezvinodiwa zvekunonoka uye kudzoserwa kwedata, kunyanya kune vatengi vemari, avo vaive nezvinodiwa zvakanyanya zvekunonoka, saka zvinodiwa zvemitsetse yakatsaurirwa zvaivewo.

Kana kuti, vashandisi vanotanga kuda granularity yakakura, senge 2.5G, 10G single-link bandwidth, uye vanodawo dziviriro yenzira mbiri kuti vave nechokwadi chekuti LSA inosvika 4 kusvika 5 9s.

 Kunyangwe zvakadaro, simba rekuvandudzwa kweInternet rinoshamisa, uye mafambiro ebhizinesi akadai sekutumira malogi uye kuenderana kwedatabase ari kukura. Tichifunga nezvemutengo, nguva yekutumira, mhando yebasa, nezvimwewo, makambani makuru (kunyanya makambani eInternet ane data guru seGoogle neFB) akatanga kuvaka maDCI network nekurenda mafiber e-optical asina vashandisi. Pakutanga kwekushandisa fiber ye-optical isina chinhu, yaivewo nzira yekumhanyisa chiratidzo chimwe chete kuburikidza nefiber imwe chete. Semuenzaniso, fiber dze-optical dzinogona kushandisa 10G ZR module kutumira makiromita makumi masere kure. Zvisinei, dambudziko renzira iyi nderekuti kune rumwe rutivi, huwandu hwekushandiswa kwefiber ye-optical hunowedzera zvakananga nebandwidth, uye mutengo unowedzera; Dambudziko rekare uye rakaoma), uye panguva ino, bandwidth ye10G yefiber imwe chete haigone kusangana nezvinodiwa zvekukura kwebhizinesi, saka network yeDCI yakatanga nguva yeWDM.

Munguva yeWDM, nzira mbiri dzakaonekwa muDCI network, kureva, coarse wavelength division CWDM uye dense wavelength division DWDM. Zvichienderana nemitengo, vamwe vashandisi vekutanga vakashandisa 10G CWDM optical modules yeDCI interconnection vachishandisa tekinoroji yeCWDM. Zvisinei, iyi system inotsigira kusvika kumawave gumi nematanhatu e10G, uye EDFA haigone kuwedzera chiratidzo pawavelength yeCWDM. , uye passive relay distance yayo yakaganhurirwawo. Saka, sezvo kudiwa kwekutumira data rakakura kuri kuramba kuchikwira, vashandisi vanofanirwa kutanga kushandisa masisitimu eDWDM ane kugona kwepamusoro uye mashandiro.
