Umsuka wenethiwekhi ye-DCI
Ekuqaleni, isikhungo sedatha sasilula, sinamakhabhinethi ambalwa + ama-air conditioners ambalwa aphezulu ekamelweni elingahleliwe, bese kuba amandla omuzi avamile + ama-UPS ambalwa, futhi yaba isikhungo sedatha.Nokho, lolu hlobo lwesikhungo sedatha luncane ngesilinganiso futhi luphansi ngokuthembeka.I-inthanethi, ebilokhu ithuthuka ngokuhlanya kusukela ekupheleni kweminyaka yawo-1990, iphinde yandisa isidingo sezikhungo zedatha.Ngakho-ke, kunenkinga engaxazululeki kulolu hlobo lwesikhungo sedatha: isikhala esinganele , Ukunikezwa kwamandla okwanele, akukho ukuphindaphinda, futhi akukho siqinisekiso se-SLA, okwenza abasebenzisi baqale ukuthola esinye isikhungo sedatha sokuthunyelwa kwebhizinisi.Ngalesi sikhathi, isikhungo esisha sedatha kanye nesikhungo sedatha esidala saqala ukuba nezidingo zokuxhumanisa inethiwekhi, okuholela kunethiwekhi yokuqala ye-DCI, okungukuthi, i-Data Center Inter-connect, ehlanganisa ubuchwepheshe obusezingeni lenethiwekhi ebonakalayo kanye nezinga lenethiwekhi elinengqondo.
Inethiwekhi yokuqala ye-DCI yayixhunywe ngokuqondile nge-inthanethi.Kamuva, kucatshangelwa ukuphepha, ukubethela kwasetshenziswa, ikhwalithi yesevisi yacatshangelwa, imigqa ezinikezele isetshenzisiwe, futhi umkhawulokudonsa wawuxhunywe ngokuqondile nge-fiber optical.
Ukuthuthukiswa kwenethiwekhi ye-DCI
Ukuthuthukiswa kwamanethiwekhi e-DCI kusukela ekuxhumekeni kwe-inthanethi, kuya emigqeni eminingi ezinikele engu-M, ekuxhumaneni kwamanje kwe-multi-10T WDM akusona isikhathi eside, ngokusobala, kuyimpendulo ekuthuthukisweni kwe-inthanethi.Ekuqaleni, abasebenzisi basebenzisa umhubhe we-VPN yenethiwekhi yomphakathi ukuze badlulisele izinsiza zabo ngqo ngenethiwekhi yomphakathi.Le ndlela ithintwa izindawo ezihlukahlukene zenethiwekhi yomphakathi (ukuminyana komkhawulokudonsa wenethiwekhi yomhlaba wonke, umzila ophansi, i-jitter yomugqa, ukusetha kabusha isixhumanisi, i-firewall, njll.) Ithonywe yizindleko nezindleko, ifanele ithrafikhi encane, izidingo zekhwalithi yomkhawulokudonsa ophansi, okungezona. -isikhathi sangempela, nezimfuneko zokuphepha eziphansi.Kamuva, ibhizinisi esikhungweni sedatha ladonsa ukunakwa okwengeziwe, futhi ibhizinisi laqala ukukhula kancane kancane ukuthunyelwa, futhi inani lamaseva landa ngokulinganayo..Ngemuva kokuthi inani elikhulu lezinsizakalo lisatshalaliswa, lezi zinsizakalo ezidluliselwa ngenethiwekhi zinomthelela okhulayo ezinkampanini nasezimbonini, ngakho-ke izidingo zenethiwekhi nazo ziya ngokuya zikhuphuka, kuqala kuboniswe ku-bandwidth kanye nokuzinza kwesixhumanisi, ngakho abasebenzisi besikhungo sedatha baqala. emigwaqweni enikezelwe yesekethe yomsebenzisi oqashisiwe, imigqa enikezelwe ye-MSTP ethwelwe nge-SDH isiqalile ukuthengisa kahle ngenxa yokuzinza kwayo okuphezulu, umkhawulokudonsa omkhulu, kanye nezinga eliphezulu lokuphindaphinda kwabasebenzisi.
Kamuva, ngokuthuthuka okuqhubekayo kwebhizinisi, idatha phakathi kwezikhungo zedatha yaqala ukuba nezidingo zokubambezeleka nokungadingeki, ikakhulukazi kumakhasimende ezezimali, abenezidingo eziphakeme kakhulu zokulibaziseka, ngakho-ke izidingo zemigqa ezinikele nazo
anda;Noma, abasebenzisi baqala ukudinga imbudumbudu enkulu, efana ne-2.5G, 10G yomkhawulokudonsa wesixhumanisi esisodwa, futhi idinga nokuvikelwa kwemizila emibili ukuze kuqinisekiswe ukuthi i-LSA ifinyelela ku-4 kuya ku-5 9s.
Noma kunjalo, amandla okuthuthukiswa kwe-inthanethi ayamangalisa, futhi izitayela zebhizinisi ezifana nokudluliswa kwelogi nokuvumelanisa kwedathabhesi ziyakhula.Uma kucatshangelwa izindleko, isikhathi sokulethwa, ikhwalithi yesevisi, njll., izinkampani eziphezulu (ikakhulukazi izinkampani ze-inthanethi ezinedatha enkulu njenge-Google ne-FB) seziqalile ukwakha amanethiwekhi e-DCI ngokuqasha ama-optical fibers angenalutho ngaphandle kwama-opharetha.Ekuqaleni kokusebenzisa i-fiber optical engenalutho, futhi bekuyindlela yokusebenzisa isignali eyodwa ngokusebenzisa i-fiber optical eyodwa.Isibonelo, ipheya lemicu yokubona lingasebenzisa imojula ye-10G ZR ukudlulisa amakhilomitha angama-80.ngokwanele.Kodwa-ke, ukungalungi kwale ndlela ukuthi ngakolunye uhlangothi, inani lokusetshenziswa kwe-fiber optical likhuphuka ngokuhambisana nomkhawulokudonsa, futhi izindleko ziyanda;Inkinga yesikhathi eside futhi enzima), futhi ngalesi sikhathi, i-bandwidth ye-10G ye-fiber eyodwa ayikwazi ukuhlangabezana nezidingo zokukhula kwebhizinisi, ngakho-ke inethiwekhi ye-DCI yaqala inkathi ye-WDM.
Esikhathini se-WDM, izindlela ezimbili zavela kunethiwekhi ye-DCI, okungukuthi, i-CWDM ye-wavelength ehlukanisayo kanye ne-dense wavelength division DWDM.Ngokusekelwe ekucatshangelweni kwezindleko, abanye abasebenzisi bokuqala basebenzisa amamojula we-10G CWDM optical for DCI interconnection usebenzisa ubuchwepheshe be-CWDM.Nokho, lolu hlelo lusekela amagagasi afika ku-16 we-10G, futhi i-EDFA ayikwazi ukukhulisa isignali kubude begagasi be-CWDM., kanye nebanga layo elidluliswayo elilinganiselwe nalo lilinganiselwe.Ngakho-ke, njengoba isidingo sokudluliswa kwedatha ngezinga elikhulu siqhubeka sikhuphuka, abasebenzisi kufanele baqale ukusebenzisa izinhlelo ze-DWDM ezinomthamo ophezulu nokusebenza.
