Chiyambi cha netiweki ya DCI
Poyamba, malo osungira deta anali osavuta, okhala ndi makabati angapo + ma air conditioner ochepa okhala ndi P yayikulu mchipinda chosasinthika, kenako magetsi amodzi amzinda + ma UPS angapo, ndipo adakhala malo osungira deta. Komabe, malo osungira deta amtunduwu ndi ochepa kwambiri komanso odalirika. Intaneti, yomwe yakhala ikukula kwambiri kuyambira kumapeto kwa zaka za m'ma 1990, yawonjezeranso kufunikira kwa malo osungira deta. Chifukwa chake, pali vuto losathetsedwa mu malo osungira deta amtunduwu: malo osakwanira, magetsi osakwanira, kusakhalapo kwa deta, komanso kusakhalapo kwa chitsimikizo cha SLA, zomwe zimapangitsa ogwiritsa ntchito kuyamba kupeza malo ena osungira deta kuti agwiritse ntchito bizinesi. Panthawiyi, malo atsopano osungira deta ndi malo akale osungira deta anayamba kukhala ndi zofunikira zolumikizirana ndi maukonde, zomwe zinapangitsa kuti pakhale netiweki yoyamba ya DCI, yomwe ndi Data Center Inter-connect, yomwe imaphatikizapo ukadaulo pamlingo wa netiweki yeniyeni komanso mulingo wa netiweki wolondola.
Netiweki yoyamba ya DCI idalumikizidwa mwachindunji kudzera pa intaneti. Pambuyo pake, poganizira za chitetezo, kubisa kunagwiritsidwa ntchito, mtundu wa ntchito unaganiziridwa, mizere yapadera idagwiritsidwa ntchito, ndipo bandwidth idalumikizidwa mwachindunji ndi ulusi wa kuwala.
Kukula kwa netiweki ya DCI
Kupanga ma network a DCI kuchokera pa intaneti yolumikizirana, kupita ku mizere ingapo yodzipereka ya M, kupita ku kulumikizana kwa WDM kwa multi-10T komwe kulipo si nthawi yayitali, kwenikweni, ndi yankho ku chitukuko cha intaneti. Poyamba, ogwiritsa ntchito amagwiritsa ntchito njira ya VPN yapagulu kuti atumize ntchito zawo mwachindunji kudzera pa intaneti yapagulu. Njirayi imakhudzidwa ndi malo osiyanasiyana a netiweki yapagulu (kuchuluka kwa bandwidth yapadziko lonse, njira yocheperako, kugwedezeka kwa mzere, kubwezeretsa ulalo, firewall, ndi zina zotero). Motsogozedwa ndi mtengo ndi mtengo, ndi yoyenera magalimoto ang'onoang'ono, zofunikira zamtundu wotsika wa bandwidth, zosowa zanthawi yeniyeni, komanso chitetezo chochepa. Pambuyo pake, bizinesi yomwe ili mu data center idakopa chidwi chochulukirapo, ndipo bizinesiyo idayamba kuwonjezera pang'onopang'ono kutumizidwa, ndipo chiwerengero cha ma seva chidawonjezeka molunjika. Pambuyo poti mautumiki ambiri atumizidwa, mautumikiwa omwe amatumizidwa kudzera mu netiweki amakhudza kwambiri makampani ndi mafakitale, kotero zofunikira pa netiweki zikukweranso, zomwe zimawonekera koyamba mu bandwidth ndi kukhazikika kwa linki, kotero ogwiritsa ntchito malo osungira deta ayamba kugwiritsa ntchito mizere yodzipereka ya opareshoni yobwereka, mizere yodzipereka ya MSTP yomwe imayendetsedwa pa netiweki ya SDH yayamba kugulitsa bwino chifukwa cha kukhazikika kwawo kwakukulu, bandwidth yayikulu, komanso kuchuluka kwa opareshoni.
Pambuyo pake, ndi chitukuko cha bizinesi chomwe chinkapitirirabe, deta pakati pa malo osungira deta inayamba kukhala ndi zofunikira pakuchedwa ndi kubwezeredwa, makamaka kwa makasitomala azachuma, omwe anali ndi zofunikira kwambiri pakuchedwa, kotero zofunikira pa mizere yodzipereka zinalinso
Kuwonjezeka; Kapena, ogwiritsa ntchito amayamba kufunikira kuchuluka kwakukulu kwa ma granularity, monga 2.5G, 10G single-link bandwidth, komanso amafunikira chitetezo cha dual-routing kuti atsimikizire kuti LSA ifika 4 mpaka 5 9s.
Ngakhale zili choncho, mphamvu ya chitukuko cha intaneti ndi yodabwitsa, ndipo zochitika zamabizinesi monga kutumiza ma log ndi kulumikiza database zikukulirakulira. Poganizira za mtengo, nthawi yotumizira, mtundu wautumiki, ndi zina zotero, makampani apamwamba (makamaka makampani a pa intaneti omwe ali ndi deta yayikulu monga Google ndi FB) ayamba kumanga ma netiweki a DCI pobwereka ulusi wopanda ma operators. Poyamba kugwiritsa ntchito ulusi wopanda ma operating, inalinso njira yoyendetsera chizindikiro chimodzi kudzera mu ulusi umodzi wowala. Mwachitsanzo, ulusi wowala ungagwiritse ntchito module ya 10G ZR kuti itumize makilomita 80 kutali. Komabe, vuto la njira iyi ndikuti mbali imodzi, kuchuluka kwa kugwiritsa ntchito ulusi wowala kumawonjezeka motsatizana ndi bandwidth, ndipo mtengo umawonjezeka; Vuto lakale komanso lovuta), ndipo panthawiyi, bandwidth ya 10G ya ulusi umodzi sungakwaniritse zosowa za kukula kwa bizinesi, kotero netiweki ya DCI inayamba nthawi ya WDM.
Mu nthawi ya WDM, njira ziwiri zinaonekera mu netiweki ya DCI, ndiko kuti, coarse wavelength division CWDM ndi dense wavelength division DWDM. Kutengera ndi mtengo woganizira, ogwiritsa ntchito ena oyamba adagwiritsa ntchito ma module a 10G CWDM optical pa DCI interconnection pogwiritsa ntchito ukadaulo wa CWDM. Komabe, makinawa amathandizira mafunde okwana 16 a 10G, ndipo EDFA singathe kukulitsa chizindikiro pa wavelength ya CWDM., ndipo mtunda wake wotumizirana ndi wochepa. Chifukwa chake, pamene kufunikira kwa kutumiza deta kwakukulu kukupitirira kukwera, ogwiritsa ntchito ayenera kuyamba kugwiritsa ntchito makina a DWDM okhala ndi mphamvu komanso magwiridwe antchito apamwamba.
