Lapho abanikazi bezikhungo zedatha bakha ukuxhumana kwenethiwekhi yesikhungo sedatha, babheka kakhulu izinkinga ezifana ne-bandwidth enkulu, ukubambezeleka okuphansi, ubuningi obukhulu, ukuthunyelwa okusheshayo, ukusebenza okulula nokugcinwa, kanye nokuthembeka okuphezulu. Njengamanje, ubuchwepheshe be-OTN obukhulu obujwayelekile bulawulwa kakhulu abakhiqizi bemishini yezokuxhumana abakhulu (ama-chip axoxwa ngawodwana), njengeHuawei, i-ZTE, ne-Aran. Amakhasimende amakhulu ababhekene nawo ngabaqhubi bezokuxhumana bendabuko, ngakho-ke izici zomkhiqizo ze-OTN zenzelwe kakhulu ukuhlangabezana nezici zesevisi zalaba baqhubi. Ngenxa yalokhu, i-OTN isetshenziswa kakhulu ezinhlelweni zenethiwekhi ze-DCI embonini ye-inthanethi. Izinkinga eziningi ezingavumelani.
Izici zemishini ye-OTN ziyizinkinga ezifanayo ezibhekene ne-DCI, izindleko zebhizinisi ezicebile, ikhono eliqinile le-OAM lenethiwekhi, amakhono okuhlela kanye nokuhlanganisa ama-bandwidth ahlukene e-granular, ukubekezelela amaphutha emigqa ngaphansi kwezimo zebanga elide, kanye nokusetshenziswa komshini oqondile we-voltage ephansi. Izici ezifana nesilinganiso esiphansi sokusetshenziswa kwamandla kwemishini.
1. Amakhono okusebenzisa imali ebhizinisini acebile adinga abasebenzi be-O&M ukuba babe ngochwepheshe kakhudlwana, bathembele kakhulu ekusekelweni kobuchwepheshe okuvela kubakhiqizi, futhi babe nobuchwepheshe obuvaliwe kakhudlwana.
2. Amakhono e-OAM anamandla, amazinga angaguquki, ukuxhumana okunzima nokuzimele kakhulu namanethiwekhi ahlukene, kanye nemisebenzi engenamsebenzi nakho kuletha izindleko ezengeziwe zokudlulisa nokusebenza kunethiwekhi ye-DCI.
3. Amakhono ahlukene okuhlela ama-granule enza isakhiwo sohlaka lwe-encapsulation yesevisi sibe nzima kakhulu futhi sibe nama-byte ahlanganisiwe kakhulu.
4. Ukubekezelela amaphutha emigqa emide kwenza i-algorithm ye-FEC ibe yinkimbinkimbi, idle imali eningi futhi ithatha isikhathi eside ukuyicubungula
5. Imodi yokunikezwa kwamandla kagesi engu-48V-DC yemishini ye-OTN ihlukile kumakhabhinethi ajwayelekile angu-19-intshi angu-220V-AD (noma angu-240V-DC) asetshenziswa ezikhungweni eziningi zedatha. Ukufakwa kuyinkimbinkimbi futhi kudinga ukuguqulwa kwamandla egumbini lekhompyutha.
6. Imishini yendabuko ye-OTN inohlaka olukhulu, olungafanele ukufakwa kumakhabethe ajwayelekile, futhi ubuningi bomthamo abuphezulu. Ukwandiswa kamuva kuyakhathaza futhi kudinga ukuthi amakhabethe athuthwe noma akhiwe kabusha.
Njengamanje, inethiwekhi yethu ye-DCI ihloselwe kakhulu ukuhlinzeka ngamapayipi edatha yesikhungo sedatha ehlukahlukene. Izici eziyinhloko zemodeli yebhizinisi yilezi: izidingo ze-granularity ye-bandwidth ehlanganisiwe neyodwa, i-bandwidth enkulu, izinsizakalo zesikhungo sedatha ehlukahlukene (ikakhulukazi i-IDC esebenzayo eminingi, izinsizakalo zedatha enkulu)) inezidingo ze-latency ephansi kanye nezidingo eziphezulu zokuzinza kwenethiwekhi; ngesikhathi esifanayo, ngenxa yokuntuleka kwabasebenzi abangochwepheshe nabachwepheshe abafanele embonini ye-inthanethi, ukusebenza nokugcinwa kwamanethiwekhi e-DCI kudingeka kube “lula” “lula” futhi “lula” – izinto ezibalulekile zishiwo kathathu (kuphi? Akulona uhlobo lwenethiwekhi?); ukuthuthukiswa okuqhumayo kwe-inthanethi kwenza izidingo zomjikelezo wokwakha nowokwandisa zibe zifushane (umjikelezo wokwandiswa kwe-OTN wabasebenzisi ngokuvamile uphakathi kwesigamu sonyaka kuya onyakeni owodwa, kuyilapho izidingo zokwandiswa kwe-DCI ye-inthanethi ziyinyanga eyodwa kuya kwezi-3), Ngakho-ke, kubalulekile ukucindezela isikhathi kuzo zonke izici.
Ngakho-ke, i-OTN inikeza ikhambi elisebenzisekayo le-DCI, kodwa i-OTN ayisona neze ikhambi elifanele kakhulu le-DCI. Manje njengoba inethiwekhi ye-DCI ikhula ngokushesha, kunesidingo esikhulayo sezixazululo ezifanele zokuxazulula izinkinga kusukela ezindleleni kuya ekwakhiweni, ekusebenzeni nasekulungisweni. Izinkinga ezahlukahlukene ezihlangatshezwane nazo. Futhi lezi zinkinga azilutho ngaphandle kwezidingo eziyisithupha zenethiwekhi ye-DCI (ububanzi obukhulu, ukubambezeleka okuphansi, ukuminyana okuphezulu, ukuthunyelwa okusheshayo, ukusebenza okulula nokugcinwa, kanye nokuthembeka okuphezulu):
1. I-bandwidth enkulu, inethiwekhi yokudlulisa ye-DCI ayinazo izinhlobo ezicebile zama-granule njengezi-opharetha, ama-bandwidth granule enethiwekhi yokudlulisa ye-DCI alula, okwamanje asetshenziswa kakhulu yi-10G noma i-100G, esikhathini esizayo yi-200G/400G, njll., ngakho-ke asikho isidingo sokwenza nge-bandwidth enkulu ye-bandwidth kwezinye izinhlayiya. Ngenxa yokuthi ibanga lenethiwekhi yokudlulisa ye-DCI ngokuvamile alide kakhulu, kusetshenziswa uhlelo lwe-400G olusekelwe ku-200G PM-16QAM dual-carrier modulation, ibanga lokudlulisa ngaphandle kokudluliselwa kukagesi lingaba cishe ngamakhilomitha angu-500 (PM-64QAM cishe ngamakhilomitha angu-200), ukuze ukudluliselwa kwe-DCI ngemuva kwe-metro kunganqunyelwa yibanga.
2. Izidingo zebhizinisi ze-DCI zokubambezeleka okuphansi, ikakhulukazi lapho kusetshenziswa i-cloud computing ukuhlanganisa izinsiza kanye nezikhungo zedatha ezisebenzayo eziningi, ukubambezeleka kubalwa ezingeni le-microsecond, ngakho-ke isikhathi sokudlulisa idatha kufanele sibe sifushane ngangokunokwenzeka, sifisa ukudlula isivinini sokukhanya. Susa umsebenzi wokucubungula idatha ongadingekile futhi unciphise izindlela zokudlulisa isignali. Isibonelo, ngokususa umsebenzi we-SD-FEC osetshenziswa yi-100G OTN, i-back-to-back eyodwa ingonga ama-microsecond angu-200, futhi ukususa i-cross-level OTN encapsulation kungonga amashumi ama-microsecond, futhi kusetshenziswe ngokunengqondo i-hubspoke topology yezinsizakalo ezibalulekile ukuqinisekisa indlela emfushane kakhulu. Vele, ingabambisana ne-MPLS kanye ne-QOS ezingeni le-IP ukuzama ukuqinisekisa ukuthi ukubambezeleka ezingeni lokudlulisa idatha nakho kungcono.
3. Ubuningi obukhulu, i-U eyodwa, noma i-2U, ingafinyelela umkhawulokudonsa ofinyelela ku-T, ungqimba lwe-DWDM optical kanye nokuhlukanisa ungqimba lwesignali kagesi, ithuthukise isikhombimsebenzisi sobuningi bedivayisi, futhi inciphise usayizi we-module ye-optical. Isibonelo, ukusetshenziswa kwamamojula e-QSFP28 optical kungaqinisekisa ukuthi amandla okufinyelela e-100G edivayisi eyodwa athuthukiswa kakhulu, futhi ukusetshenziswa kwamamojula e-CFP2 daylighting ohlangothini lomugqa kungaqinisekisa ukuthi umkhawulokudonsa wokudlulisa wedivayisi iyonke uthuthukisiwe, i-1U ingaba yi-1.6T, i-3.2T. Njengamanje, imikhiqizo eminingi ehlobene nayo ivele emhlabeni, njenge-ADVA, i-coriant, i-ciena nezinye izinkampani. Vele, i-Huawei yasekhaya nayo yethule imikhiqizo ehlobene engu-902. Kodwa-ke, njengoba kuqedwa lesi sihloko, kubonakala sengathi ukuhlolwa kokufinyelela kwenethiwekhi koMnyango Wezimboni Nobuchwepheshe Bolwazi akukaqedwa. Ubuningi obukhulu buzobangela ukusetshenziswa kwamandla aphezulu kanye nokushabalaliswa kokushisa. Ngakho-ke, indlela yokuqala yokusabalalisa ukushisa kwe-OTN yomoya wesobunxele nowesokudla ophumayo, kanye nomoya ophezulu nowehlayo ophumayo nowesobunxele kufanele ilahlwe.
Izidingo zokupholisa idivayisi.
4. Ukufakwa okusheshayo, kusetshenziswa i-rack ye-IDC engu-19-intshi ejwayelekile yamanje, efana nesimo samaseva ajwayelekile, kusetshenziswa i-AC-220V yokuphakelwa kwamandla ngqo, kususa isidingo sokuguqulwa kwamandla nekhabhinethi, nokuqaphela ukuthi izimpahla zingafakwa emashalofini ngokushesha ngemva kokufika egumbini lekhompyutha, futhi zingalungiswa ngemva kokufakwa kokunikezwa kwamandla. ibhizinisi, futhi zenze umsebenzi omuhle emsebenzini wokwamukelwa okujwayelekile ukuze kufezwe ukuthunyelwa okusheshayo.
5. Ukusebenza okulula nokugcinwa, izidingo zemodeli yebhizinisi le-DCI, ibanga phakathi kwezikhungo zedatha ngeke libe kude kakhulu, kanye nokuphathwa okuyinkimbinkimbi, i-OAM neminye imisebenzi akudingekile ukudlala indima enkulu kulesi simo, futhi ukucubungula okuyinkimbinkimbi nakho kuyancishiswa. Kuthuthukisa ukusebenza kahle kokudluliselwa kwedatha, kuthuthukisa isikhathi sokucubungula idatha, futhi kunezidingo eziphakeme zobuchwepheshe futhi kuvaliwe kakhulu. Ukuxhuma amasignali ngqo nge-Ethernet kuqeda ukuphathwa okuyinkimbinkimbi kwe-OTN, ngakho onjiniyela benethiwekhi ye-IP bendabuko bangasebenzisa futhi balondoloze uhlelo lwe-DCI. Ngemva kokuhlanganisa izixhumi ezintsha ezibheke enyakatho njengemodeli ye-YANG, i-REST API, kanye ne-netconf, ukuphathwa kwemishini yokudlulisa i-DCI kanye nokuphathwa kwemishini yenethiwekhi ye-IP kuthuthukiswa ngesixhumi esifanayo, ukuze kuqhutshwe kangcono ukuphathwa kwenethiwekhi okuhlanganisiwe okusekelwe epulatifomu.
6. Ukuthembeka okuphezulu, umzila wezinto eziningi kanye nobuchwepheshe bokuvikela obungazi ngesendlalelo esiphezulu buzoqhubeka nokudlala indima kunethiwekhi yokudlulisa ye-DCI. Ukwehluleka ezingeni lesixhumanisi esiyisisekelo akufanele kube nomthelela ezinsizeni ngaphandle kokuthi kuphazamiseke ngokuphelele. Ukubona noma umthelela, kungaba ukushintsha ukuvikela, ukushaqeka kwesixhumanisi, ukwanda kokubambezeleka, njll.
