yini dci.

Ukuze kuhlangatshezwane nezidingo zamabhizinisi zosekelo lwezinsiza eziningi kanye nabasebenzisi besipiliyoni senethiwekhi yekhwalithi ephezulu kuzo zonke izindawo, izikhungo zedatha azisezona “iziqhingi”;badinga ukuxhunywa ukuze babelane noma benze ikhophi yasenqolobaneni yedatha futhi bazuze ukulinganisa komthwalo.Ngokombiko wocwaningo lwemakethe, imakethe yokuxhumanisa isikhungo sedatha yomhlaba wonke kulindeleke ukuthi ikhule ifinyelele ezigidini eziyizinkulungwane ezingama-7.65 zamadola aseMelika ngo-2026, ngenani lokukhula elihlanganisiwe lonyaka lika-14% ukusuka ngo-2021 kuya ku-2026, futhi ukuxhumana kwesikhungo sedatha sekuphenduke umkhuba.

Okwesibili, yini ukuxhumana kwesikhungo sedatha

I-Data Center Interconnect (DCI) yisisombululo senethiwekhi esenza izikhungo ezixhumanisa idatha zikwazi ukuxhumana zodwa.Ifaka ukuxhumeka okuvumelana nezimo, ukusebenza kahle okuphezulu, ukuphepha, nokusebenza nokugcinwa lula (i-O&M), ehlangabezana nezimfuneko zokushintshisana kwedatha okuphumelelayo nokutholwa kwenhlekelele phakathi kwezikhungo zedatha.

Ukuxhumana kwesikhungo sedatha kungahlukaniswa ngokwebanga lokudluliswa kwesikhungo sedatha nendlela yokuxhuma inethiwekhi:

Ngokwebanga lokudlulisela:

I-1) Ibanga elifushane: phakathi kwamakhilomitha angu-5, ikhebula evamile isetshenziselwa ukubona ukuxhumana kwezikhungo zedatha epaki;

2) Ibanga eliphakathi: phakathi kwama-80 km, ngokuvamile libhekisela ekusetshenzisweni kwamamojula okukhanya emadolobheni aseduze noma ezindaweni ezimaphakathi ukuze kuzuzwe ukuxhumana;

I-3) Ibanga elide: izinkulungwane zamakhilomitha, ngokuvamile ibhekisela emishinini yokudlulisa amehlo ukuze kuzuzwe ukuxhumana kwesikhungo sedatha ebangeni elide, njengenethiwekhi yekhebula elingaphansi kolwandle;

Ngokuhambisana nendlela yokuxhumana:

1) Uxhumano lwenethiwekhi yesithathu: inethiwekhi engaphambili yezikhungo zedatha ehlukene ifinyelela isikhungo sedatha ngasinye ngenethiwekhi ye-IP, lapho isayithi lesikhungo sedatha esiyinhloko sihluleka, idatha ekopishelwe kusayithi elindile ingatholwa, futhi uhlelo lokusebenza ingaqalwa kabusha ngaphakathi kwefasitela lokuphazamiseka okufushane, kubalulekile ukuvikela le thrafikhi ekuhlaselweni okunonya kwenethiwekhi futhi kutholakala njalo;

2) Uxhumano lwenethiwekhi Yesendlalelo sesi-2: Ukwakha inethiwekhi ye-Layer 2 (VLAN) enkulu phakathi kwezikhungo zedatha ezihlukene ngokuyinhloko kuhlangabezana nezimfuneko zokufuduka okunamandla okubonakalayo kwamaqoqo amaseva.Lezi zinto ezilandelayo kufanele zicatshangelwe:

Ukubambezeleka okuphansi: Ukuxhumana kwesendlalelo sesi-2 phakathi kwezikhungo zedatha kusetshenziselwa ukusebenzisa ukuhlela okukude kwe-VM kanye nezinhlelo zokusebenza ezikude zeqoqo.Ukuze kuzuzwe lokhu, izidingo zokubambezeleka zokufinyelela ukude phakathi kwe-VMS nokugcinwa kweqoqo kufanele kuhlangatshezwane nazo

Umkhawulokudonsa ophezulu: Enye yezidingo eziyinhloko zokuxhumanisa isikhungo sedatha ukuqinisekisa ukufuduka kwe-VM kuzo zonke izikhungo zedatha, okubeka izidingo eziphezulu kumkhawulokudonsa.

Ukutholakala Okuphezulu: Enye yezindlela eziphumelela kakhulu zokuthuthukisa ukutholakala ukuklama izixhumanisi eziyisipele ukuze usekele ukuqhubeka kwebhizinisi.

3) Ukuxhumana kwenethiwekhi yesitoreji: Ukuphindaphindwa kwedatha phakathi kwesikhungo esiyinhloko kanye nesikhungo sokuhlenga izinhlekelele kwenziwa ngobuchwepheshe bokudlulisa (i-bare optical fiber, i-DWDM, i-SDH, njll.).

Okwesithathu, indlela yokufinyelela ukuxhumana kwesikhungo sedatha

I-1) Ubuchwepheshe be-MPLS: Uhlelo lokuxhumanisa olusekelwe kubuchwepheshe be-MPLS ludinga ukuthi inethiwekhi yokuxhumanisa phakathi kwezikhungo zedatha iyinethiwekhi eyinhloko yokuthumela ubuchwepheshe be-MPLS, ukuze uhlaka oluqondile lwe-2 ukuxhumeka kwezikhungo zedatha kuqedwe ngokuqondile nge-VLL ne-VPLS.I-MPLS ihlanganisa ubuchwepheshe be-Layer 2 VPN kanye nobuchwepheshe be-Layer 3 VPN.Iphrothokholi ye-VPLS ubuchwepheshe be-Layer 2 VPN.Inzuzo yayo ukuthi ingakwazi ukusebenzisa kalula ukuthunyelwa kwenethiwekhi ye-metro/wide area, futhi isetshenziswa ezimbonini eziningi.

I-2) Ubuchwepheshe bomhubhe we-IP: Kuwubuchwepheshe be-packet encapsulation, obungakwazi ukubona ukuhlangana kwenethiwekhi okungafani kwe-2 phakathi kwezikhungo eziningi zedatha;

3) Ubuchwepheshe bomhubhe we-VXLAN-DCI: Isebenzisa ubuchwepheshe be-VXLAN, ingakwazi ukubona ukuxhumeka kwe-Layer 2 / Layer 3 yamanethiwekhi esikhungo sedatha eminingi.Ngokusekelwe ekuvuthweni kwamanje kobuchwepheshe kanye nesipiliyoni secala lebhizinisi, inethiwekhi ye-VXLAN iyavumelana nezimo futhi iyalawuleka, ukuhlukaniswa okuvikelekile, nokuphathwa nokulawula okumaphakathi, okufanele isimo sesikhathi esizayo sokuxhunywa kwesikhungo sedatha eminingi.

4. Izici zesixazululo sokuxhumanisa isikhungo sedatha nezincomo zomkhiqizo

Izici zeskimu:

I-1) Ukuxhumana okuguquguqukayo: Imodi yokuxhumana eguquguqukayo, ithuthukise ukuguquguquka kwenethiwekhi nokuqina, ukuhlangabezana nokufinyelela ku-inthanethi, ukusatshalaliswa kokusabalalisa kwezikhungo zedatha, inethiwekhi yamafu eyingxube nokunye ukunwetshwa okuvumelana nezimo phakathi kwezikhungo eziningi zedatha;

2) Ukuvikeleka okuphumelelayo: Ubuchwepheshe be-DCI busiza ukugcwalisa isikhungo sedatha ngokugcwele, ukwabelana ngezinsiza ezibonakalayo nezibonakalayo kuzo zonke izifunda ukuze kuthuthukiswe umthwalo womsebenzi wedatha, futhi kuqinisekiswe ukusatshalaliswa okuphumelelayo kwethrafikhi yenethiwekhi phakathi kwamaseva;Ngesikhathi esifanayo, ngokusebenzisa ukubethela okunamandla nokulawula ukufinyelela okuqinile, ukuphepha kwedatha ebucayi njengokuthengiselana kwezezimali nolwazi lomuntu siqu kuqinisekisiwe ukuze kuqinisekiswe ukuqhubeka kwebhizinisi;

4) Yenza kube lula ukusebenza nokunakekelwa: Enza ngendlela oyifisayo izinsizakalo zenethiwekhi ngokwezidingo zebhizinisi, futhi ufeze inhloso yokwenza lula ukusebenza nokugcinwa nokugcinwa ngokuchazwa kwesofthiwe/inethiwekhi evulekile.

I-HUA6800 – 6.4T DCI WDM yesikhulumi sokudlulisa

I-HUA6800 ingumkhiqizo wokudlulisa we-DCI omusha.I-HUA6800 inezici zosayizi omncane, ukufinyelela kwenkonzo yamandla amakhulu kakhulu, ukudluliswa kwebanga elide, ukusebenza okulula nokulula nokuphathwa kokugcinwa, ukusebenza okuphephile, ukonga amandla kanye nokunciphisa ukukhishwa.Ingakwazi ukuhlangabezana ngokuphumelelayo nezidingo zebanga elide, Izidingo zomkhawulokudonsa omkhulu wokuxhumana nokudluliselwa kwezikhungo zedatha yomsebenzisi.

I-HUA6800 yamukela idizayini ye-modular, engasekeli kuphela ukuhlukaniswa kwezithombe zogesi ukuze kuncishiswe izindleko, kodwa futhi isekela ukuphathwa okudidiyelwe kogesi wesithombe kuhlaka olufanayo.Ngomsebenzi we-SDN, yakha ukwakheka kwenethiwekhi okuhlakaniphile futhi evulekile yabasebenzisi, isekela isixhumi esibonakalayo se-YANG esisekelwe kumthetho olandelwayo we-NetConf, futhi isekela izindlela ezihlukahlukene zokuphatha njenge-Web, i-CLI, ne-SNMP, futhi yenza kube lula ukusebenza nokunakekelwa.Ilungele amanethiwekhi asemqoka afana namanethiwekhi kazwelonke omgogodla, amanethiwekhi omgogodla wesifundazwe, namanethiwekhi omgogodla wedolobha elikhulu, kanye nokuxhumana kwesikhungo sedatha, okuhlangabezana nezidingo zamanodi amakhulu angaphezu kwe-16T.Yinkundla yokudlulisela engabizi kakhulu embonini.Kuyisixazululo soxhumano lwe-IDC kanye nabaqhubi be-inthanethi ukuze bakhe izikhungo zedatha ezinomthamo omkhulu.
