kuyini i-dci.

Ukuze kuhlangatshezwane nezidingo zamabhizinisi okusekela izinsizakalo eziningi kanye nabasebenzisi bokuhlangenwe nakho kwenethiwekhi okuseqophelweni eliphezulu kuzo zonke izindawo, izikhungo zedatha azisezona “iziqhingi”; zidinga ukuxhunywa ukuze zabelane noma zisekele idatha futhi zifeze ukulinganisela umthwalo. Ngokusho kombiko wocwaningo lwemakethe, imakethe yomhlaba wonke yokuxhumana kwezikhungo zedatha kulindeleke ukuthi ikhule ifike kumadola ayizigidigidi ezingu-7.65 zaseMelika ngo-2026, ngesilinganiso sokukhula sonyaka esihlanganisiwe esingu-14% kusukela ngo-2021 kuya ku-2026, futhi ukuxhumana kwezikhungo zedatha sekuyinto evamile.

Okwesibili, kuyini ukuxhumana kwesikhungo sedatha

I-Data Center Interconnect (DCI) iyisisombululo senethiwekhi esenza izikhungo zedatha ezihlukene zikwazi ukuxhumana. Iqukethe ukuxhumana okuguquguqukayo, ukusebenza kahle okuphezulu, ukuphepha, kanye nokusebenza okulula nokugcinwa (O&M), okuhlangabezana nezidingo zokushintshaniswa kwedatha okuphumelelayo kanye nokubuyiselwa kwenhlekelele phakathi kwezikhungo zedatha.

Ukuxhumeka kwesikhungo sedatha kungahlukaniswa ngokwebanga lokudluliselwa kwesikhungo sedatha kanye nendlela yokuxhumeka kwenethiwekhi:

Ngokusho kwebanga lokudlulisela:

1) Ibanga elifushane: ngaphakathi kwamakhilomitha ama-5, ukuxhumanisa izintambo ezijwayelekile kusetshenziselwa ukufeza ukuxhumana kwezikhungo zedatha epaki;

2) Ibanga eliphakathi: ngaphakathi kwamakhilomitha angu-80, ngokuvamile libhekisela ekusetshenzisweni kwamamojula okukhanya emadolobheni aseduze noma ezindaweni eziphakathi nendawo ukuze kufezwe ukuxhumana;

3) Ibanga elide: izinkulungwane zamakhilomitha, ngokuvamile libhekisela emishinini yokudlulisa i-optical ukuze kufezwe ukuxhumana kwesikhungo sedatha yebanga elide, njengenethiwekhi yekhebula lomkhumbi-ngwenya;

Ngokwendlela yokuxhumana:

1) Ukuxhumana kwesendlalelo sesithathu senethiwekhi: inethiwekhi engaphambili yezikhungo zedatha ezahlukene ifinyelela isikhungo ngasinye sedatha ngenethiwekhi ye-IP, lapho isayithi lesikhungo sedatha esiyinhloko lihluleka, idatha ekopishwe kusayithi elilindile ingatholakala, futhi uhlelo lokusebenza lungaqalwa kabusha ngaphakathi kwefasitela elifushane lokuphazamiseka, kubalulekile ukuvikela le thrafikhi ekuhlaselweni kwenethiwekhi okunonya futhi itholakala njalo;

2) Ukuxhumana kwenethiwekhi ye-Layer 2: Ukwakha inethiwekhi enkulu ye-Layer 2 (VLAN) phakathi kwezikhungo zedatha ezahlukene kuhlangabezana nezidingo zokufuduka okuguquguqukayo okubonakalayo kwamaqoqo eseva. Izici ezilandelayo kufanele zicatshangelwe:

Ukubambezeleka okuphansi: Ukuxhumana kwesigaba 2 phakathi kwezikhungo zedatha kusetshenziselwa ukusebenzisa ukuhlela i-VM ekude kanye nezinhlelo zokusebenza ezikude zeqembu. Ukuze kufezwe lokhu, izidingo zokubambezeleka zokufinyelela kude phakathi kwe-VMS kanye nesitoreji seqembu kumele kuhlangatshezwane nazo.

I-bandwidth ephezulu: Enye yezidingo eziyinhloko zokuxhumeka kwesikhungo sedatha ukuqinisekisa ukufuduka kwe-VM kuzo zonke izikhungo zedatha, okubeka izidingo eziphakeme ku-bandwidth

Ukutholakala Okuphezulu: Enye yezindlela eziphumelela kakhulu zokuthuthukisa ukutholakala ukuklama izixhumanisi zokusekela ukuze kusekelwe ukuqhubeka kwebhizinisi

3) Ukuxhumana kwenethiwekhi yokugcina: Ukuphindaphindwa kwedatha phakathi kwesikhungo esiyinhloko kanye nesikhungo sokulungisa inhlekelele kufezwa ngokusebenzisa ubuchwepheshe bokudlulisa (i-fiber optical engenalutho, i-DWDM, i-SDH, njll.).

Okwesithathu, indlela yokufinyelela ukuxhumana kwesikhungo sedatha

1) Ubuchwepheshe be-MPLS: Uhlelo lokuxhumana olusekelwe kubuchwepheshe be-MPLS ludinga ukuthi inethiwekhi yokuxhumana phakathi kwezikhungo zedatha ibe yinethiwekhi eyinhloko yokusebenzisa ubuchwepheshe be-MPLS, ukuze ukuxhumana okuqondile kwezikhungo zedatha kuqedwe ngqo nge-VLL kanye ne-VPLS. I-MPLS ifaka ubuchwepheshe be-VPN be-Layer 2 kanye nobuchwepheshe be-VPN be-Layer 3. Iphrothokholi ye-VPLS ubuchwepheshe be-VPN be-Layer 2. Inzuzo yayo ukuthi ingaqalisa kalula ukuthunyelwa kwenethiwekhi ye-metro/wide area, futhi isetshenziswa ezimbonini eziningi.

2) Ubuchwepheshe bomhubhe we-IP: Buwubuchwepheshe bokufaka amaphakethe, obungenza ukuxhumana kwenethiwekhi okungajwayelekile phakathi kwezikhungo eziningi zedatha;

3) Ubuchwepheshe be-VXLAN-DCI tunnel: Isebenzisa ubuchwepheshe be-VXLAN, ingafeza ukuxhumana kwe-Layer 2 / Layer 3 kwamanethiwekhi esikhungo sedatha eningi. Ngokusekelwe ekuvuthweni kobuchwepheshe bamanje kanye nokuhlangenwe nakho kwebhizinisi, inethiwekhi ye-VXLAN iyaguquguquka futhi iyalawuleka, ihlukaniswe ngokuphephile, kanye nokuphathwa nokulawulwa okuphakathi, okufanele isimo esizayo sokuxhumana kwesikhungo sedatha eningi.

4. Izici zesisombululo sokuxhumana kwesikhungo sedatha kanye nezincomo zomkhiqizo

Izici zesikimu:

1) Ukuxhumana okuguquguqukayo: Imodi yokuxhumana eguquguqukayo, ithuthukisa ukuguquguquka kwenethiwekhi kanye nokukhula kwayo, ukuhlangabezana nokufinyelela kwe-inthanethi, ukuthunyelwa kwezikhungo zedatha ezisatshalaliswe, ukuxhumana kwe-hybrid cloud kanye nokunye ukwanda okuguquguqukayo okulula phakathi kwezikhungo zedatha eziningi;

2) Ukuphepha okusebenzayo: Ubuchwepheshe be-DCI busiza ukuthuthukisa imithwalo yemisebenzi yesikhungo sedatha ehlukahlukene, ukwabelana ngezinsizakusebenza ezibonakalayo nezibonakalayo kuzo zonke izifunda ukuze kuthuthukiswe umthwalo wedatha, futhi kuqinisekiswe ukusatshalaliswa okuphumelelayo kwethrafikhi yenethiwekhi phakathi kwamaseva; Ngesikhathi esifanayo, ngokubethela okunamandla kanye nokulawula ukufinyelela okuqinile, ukuphepha kwedatha ebucayi njengokuthengiselana kwezezimali kanye nolwazi lomuntu siqu kuqinisekisiwe ukuqinisekisa ukuqhubeka kwebhizinisi;

4) Yenza kube lula ukusebenza nokugcinwa: Yenza ngezifiso izinsizakalo zenethiwekhi ngokwezidingo zebhizinisi, futhi ufeze injongo yokwenza kube lula ukusebenza nokugcinwa ngokusebenzisa incazelo yesofthiwe/inethiwekhi evulekile.

Ipulatifomu yokudlulisa ye-HUA6800 – 6.4T DCI WDM

I-HUA6800 ingumkhiqizo wokudlulisa we-DCI omusha. I-HUA6800 inezici zobukhulu obuncane, ukufinyelela kwensizakalo yomthamo omkhulu kakhulu, ukudlulisa ibanga elide kakhulu, ukuphathwa kokusebenza nokugcinwa okulula nokulula, ukusebenza okuphephile, ukonga amandla kanye nokunciphisa ukukhishwa komoya. Ingahlangabezana ngempumelelo nezidingo zebanga elide, i-bandwidth enkulu Izidingo zokuxhumanisa kanye nokudlulisa izikhungo zedatha yomsebenzisi.

I-HUA6800 isebenzisa umklamo we-modular, ongagcini nje ngokusekela ukuhlanganiswa kwe-photoelectric ukunciphisa izindleko, kodwa futhi usekela ukuphathwa okuhlanganisiwe kwe-photoelectricity kufreyimu efanayo. Ngomsebenzi we-SDN, idala ukwakheka kwenethiwekhi okuhlakaniphile nokuvulekile kwabasebenzisi, isekela isikhombimsebenzisi semodeli ye-YANG esekelwe kuphrothokholi ye-NetConf, futhi isekela izindlela ezahlukene zokuphatha ezifana ne-Web, i-CLI, ne-SNMP, futhi yenza kube lula ukusebenza nokugcinwa. Ifanele amanethiwekhi ayinhloko afana namanethiwekhi kazwelonke omgogodla, amanethiwekhi omgogodla wesifundazwe, namanethiwekhi omgogodla wedolobha elikhulu, kanye nokuxhumeka kwesikhungo sedatha, okuhlangabezana nezidingo zama-node amakhulu angaphezu kwe-16T. Yipulatifomu yokudlulisa engabizi kakhulu embonini. Yisisombululo sokuxhumana se-IDC kanye nabaqhubi be-inthanethi ukwakha izikhungo zedatha ezinkulu.
