Agasanduku ka DCI ni iki?

Inkomoko y'umuyoboro wa DCI

 Mu ntangiriro, ikigo cy’amakuru cyari cyoroshye cyane, gifite utubati duke + ibyuma bike bikonjesha mu cyumba gisanzwe, hanyuma amashanyarazi y’umujyi umwe + UPS nke, maze kiba ikigo cy’amakuru. Ariko, ubwoko bw’ikigo cy’amakuru ni gito kandi ni gito mu buryo bwizewe. Interineti, imaze gutera imbere cyane kuva mu mpera za 1990, nayo yongereye ubwinshi bw’ibigo by’amakuru. Kubwibyo, hari ikibazo kidakemuka muri ubu bwoko bw’ikigo cy’amakuru: umwanya uhagije, amashanyarazi adahagije, nta gusubizwa inyuma, kandi nta ngwate ya SLA, bituma abakoresha batangira gushaka ikindi kigo cy’amakuru cyo gushyira mu bikorwa ubucuruzi. Muri iki gihe, ikigo gishya cy’amakuru n’ikigo gishaje cy’amakuru byatangiye kugira ibisabwa mu guhuza imiyoboro, bituma habaho umuyoboro wa mbere wa DCI, ni ukuvuga, Ikigo cy’amakuru Inter-connect, kirimo ikoranabuhanga ku rwego rw’umuyoboro ufatika n’urwego rw’umuyoboro usobanutse.

 Umuyoboro wa mbere wa DCI wahujwe mu buryo butaziguye binyuze kuri interineti. Nyuma, mu rwego rw'umutekano, hakoreshejwe uburyo bwo gufunga amakuru, harebwa ireme rya serivisi, hakoreshwa imirongo yihariye, kandi bandwidth yahujwe mu buryo butaziguye na fibre optique.

Iterambere ry'umuyoboro wa DCI

Guteza imbere imiyoboro ya DCI kuva kuri interineti, kugeza ku mirongo myinshi yagenewe M, kugeza kuri interineti ya WDM ifite ubu ya multi-10T ntabwo ari igihe kirekire, mu buryo bufatika, ni igisubizo ku iterambere rya interineti. Mu ntangiriro, abakoresha bakoresha uburyo bwa VPN bwa interineti rusange kugira ngo bohereze serivisi zabo mu buryo butaziguye binyuze kuri interineti rusange. Ubu buryo bugirwaho ingaruka n'ibidukikije bitandukanye by'imiyoboro rusange (umuyoboro mpuzamahanga w'itumanaho, inzira nke, umurongo uhindagurika, gusubizaho umurongo, umuriro w'amashanyarazi, nibindi). Bitewe n'ikiguzi n'ikiguzi, birakwiriye ku bantu bake, ibisabwa ku bwiza bw'umurongo mugari, bidakenewe mu gihe nyacyo, n'ibisabwa ku mutekano muke. Nyuma, ubucuruzi bwo muri data center bwarushijeho gukurura abantu benshi, maze ubucuruzi butangira kongera ibikorwa buhoro buhoro, kandi umubare wa seriveri wiyongera mu buryo bugororotse. Nyuma y’uko serivisi nyinshi zitanzwe, izi serivisi zoherezwa binyuze kuri interineti zigira ingaruka nyinshi ku bigo n’inganda, bityo ibisabwa kuri interineti nabyo bigenda birushaho kwiyongera, bibanza kugaragara mu buryo bwo gukwirakwiza amakuru no gukwirakwiza amakuru, bityo abakoresha ikigo cy’amakuru batangira gukoresha imirongo y’ikoranabuhanga yagenewe abakoresha, imirongo yemewe ya MSTP itwarwa kuri interineti ya SDH yatangiye kugurishwa neza bitewe n’uburyo ihagaze neza, uburyo bwo gukwirakwiza amakuru bwagutse, ndetse n’urwego rwo hejuru rwo gukwirakwiza amakuru ku bakozi.

Nyuma, bitewe n’iterambere ry’ubucuruzi rikomeje kwiyongera, amakuru hagati y’ibigo by’amakuru yatangiye kugira ibisabwa kugira ngo habeho gutinda no gusubizwa inyuma, cyane cyane ku bakiriya b’imari, bari bafite ibisabwa cyane cyane kugira ngo habeho gutinda, bityo ibisabwa ku mirongo yihariye nabyo byari

byariyongereye; Cyangwa, abakoresha batangira gukenera ubunini bwinshi, nka 2.5G, bandwidth ya 10G imwe, kandi bagakenera uburinzi bwo gukoresha inzira ebyiri kugira ngo LSA igere kuri 4 kugeza kuri 5 9s.

 Nubwo bimeze bityo, imbaraga z'iterambere rya interineti ziratangaje, kandi imikorere y'ubucuruzi nko kohereza amakuru ku mbuga nkoranyambaga no guhuza amakuru y'ibanze irimo kwiyongera. Ukurikije ikiguzi, igihe cyo gutanga, ubwiza bwa serivisi, nibindi, amasosiyete akomeye (cyane cyane amasosiyete ya interineti afite amakuru manini nka Google na FB) yatangiye kubaka imiyoboro ya DCI akodesha imiyoboro ya optique idafite abayikoresha. Mu ntangiriro yo gukoresha imiyoboro ya optique idafite, byari uburyo bwo gukoresha ikimenyetso kimwe binyuze muri fibre imwe. Urugero, imiyoboro ibiri ya optique ishobora gukoresha module ya 10G ZR kugira ngo yohereze ibirometero 80. Ariko, ikibazo cy'ubu buryo ni uko ku ruhande rumwe, ingano y'ikoreshwa rya fibre optique yiyongera ku murongo ukurikije umuyoboro, kandi ikiguzi kiriyongera; Ikibazo kimaze igihe kirekire kandi kigoye), kandi muri iki gihe, umuyoboro wa 10G wa fibre imwe ntushobora guhaza ibyifuzo by'iterambere ry'ubucuruzi, bityo umuyoboro wa DCI watangiye igihe cya WDM.

Mu gihe cya WDM, uburyo bubiri bwagaragaye mu muyoboro wa DCI, ni ukuvuga CWDM igabanyijemo uburebure bw'umurambararo n'igabanywamo uburebure bw'umurambararo bunini bwa DWDM. Hashingiwe ku kiguzi, bamwe mu bakoresha ba mbere bakoresheje module za 10G CWDM optique kugira ngo bahuze DCI bakoresheje ikoranabuhanga rya CWDM. Ariko, iyi sisitemu ishyigikira imiraba 16 ya 10G, kandi EDFA ntishobora kongera ikimenyetso ku uburebure bw'umurambararo wa CWDM., kandi intera yayo yo gusimbuza itarashyirwamo na yo ni nke cyane. Kubera iyo mpamvu, kubera ko icyifuzo cyo kohereza amakuru menshi gikomeje kwiyongera, abakoresha bagomba gutangira gukoresha sisitemu za DWDM zifite ubushobozi n'imikorere yo hejuru.
