Lapho abanikazi besikhungo sedatha bakha ukuxhumana kwenethiwekhi yesikhungo sedatha yedatha, ikakhulukazi bacabangela izindaba ezifana nomkhawulokudonsa omkhulu, ukubambezeleka okuphansi, ukuminyana okuphezulu, ukuthunyelwa okusheshayo, ukusebenza okulula nokugcinwa, nokuthembeka okuphezulu.Njengamanje, ubuchwepheshe obujwayelekile bomkhawulokudonsa omkhulu we-OTN bulawulwa ikakhulukazi abakhiqizi bemishini yezokuxhumana abaningi abakhulu (ama-chips kuxoxwa ngawo ngokwehlukana), njenge-Huawei, i-ZTE, ne-Aran.Amakhasimende ayinhloko abhekene nawo ama-telecom opharetha bendabuko, ngakho izici zomkhiqizo ze-OTN ziklanyelwe kakhulu ukuhlangabezana nezici zesevisi zalaba opharetha.Ngenxa yalokhu, i-OTN isetshenziswa kakhulu ezinhlelweni zenethiwekhi ye-DCI embonini ye-inthanethi.Izinkinga eziningi zokungezwani.
Izici zemishini ye-OTN yizinkinga ezifanayo okuhlangatshezwane nazo i-DCI, i-overhead yebhizinisi elicebile, ikhono eliqinile le-OAM lenethiwekhi, amandla okuhlela nokuphindaphinda ama-bandwidth ahlukene ayimbudumbudu, ukubekezelela iphutha lomugqa ngaphansi kwezimo zebanga elide, kanye nokusetshenziswa kwe-low-voltage eqondile. okwamanje.Izici ezifana nezinga eliphansi lokusetshenziswa kwamandla asetshenziswayo.
1. Amandla okusebenzisa imali ebhizinisini anothile adinga ukuthi abasebenzi be-O&M babe ngochwepheshe kakhudlwana, bathembele kakhulu ekusekelweni kwezobuchwepheshe okuvela kubakhiqizi, futhi babe nobuchwepheshe obuvaleke kakhudlwana.
2. Amakhono e-OAM anamandla, izindinganiso ezingaguquki, ukuxhumana okunzima nokuzimele ngokwengeziwe namanethiwekhi ahlukahlukene, kanye nemisebenzi engenamsebenzi nakho kuletha izindleko ezengeziwe zokudlulisela nokusebenza kunethiwekhi ye-DCI.
3. Amakhono ahlukene okuhlela i-granule enza uhlaka lohlaka lwe-encapsulation lwesevisi lube nzima kakhulu futhi lube nesidleke samabhayithi.
4. Ukubekezelela iphutha lomugqa webanga elide kwenza i-algorithm ye-FEC ibe yinkimbinkimbi, idle ngaphezulu futhi ithatha isikhathi eside ukucutshungulwa.
5. Imodi yokuphakela amandla engu-48V-DC yemishini ye-OTN ihlukile kumakhabethe ajwayelekile angu-19-inch 220V-AD (noma 240V-DC) asetshenziswa kuzikhungo eziningi zedatha.Ukufakwa kuyinkimbinkimbi futhi kudinga ukuguqulwa kwamandla ekamelweni lekhompyutha
6. Imishini yendabuko ye-OTN inohlaka olukhulu, olungafanelekile ukufakwa kumakhabhinethi ajwayelekile, futhi umthamo womthamo awuphezulu.Ukwandiswa kwakamuva kuyinkinga futhi kudinga ukuba amakhabethe asuswe noma akhiwe kabusha.
Njengamanje, inethiwekhi yethu ye-DCI ngokuyinhloko ihlinzeka ngamapayipi edatha yesikhungo sedatha.Izici eziyinhloko zemodeli yebhizinisi yilezi: izidingo ze-granularity yomkhawulokudonsa ohlangene kanye nowodwa, umkhawulokudonsa omkhulu, izinsizakalo zesikhungo sedatha (ikakhulukazi i-IDC esebenzayo, izinsizakalo ezinkulu zedatha) ) inezidingo eziphansi ze-latency kanye nezidingo eziphezulu zokuzinza kwenethiwekhi;ngesikhathi esifanayo, ngenxa yokuntuleka kwabasebenzi abafanelekile nabachwepheshe embonini ye-Inthanethi, ukusebenza nokugcinwa kwamanethiwekhi e-DCI kudingeka kube "lula" "lula" futhi "alula" - izinto ezibalulekile zishiwo izikhathi ezintathu (lapho u-Isn Hhayi uhlobo lwenethiwekhi?);ukuthuthukiswa kokuqhuma kwe-inthanethi kwenza izidingo zomjikelezo wokwakha nowokunweba zibe mfishane (umjikelezo wokunweba we-OTN wabaqhubi ngokuvamile uba isigamu sonyaka ukuya onyakeni owodwa, kuyilapho izidingo zokunwetshwa kwe-DCI ye-inthanethi ziyizinyanga ezi-1 kuye kwezingu-3), Ngakho-ke, kuyadingeka ukucindezela isikhathi kuzo zonke izici.
Ngakho-ke, i-OTN ihlinzeka ngesixazululo esisebenzisekayo se-DCI, kodwa i-OTN ayisona neze isixazululo esifaneleka kakhulu se-DCI.Njengoba manje inethiwekhi ye-DCI idlondlobala, kunesidingo esandayo sezixazululo ezifanele zokuxazulula izinkinga ezisukela ezindlekweni kuye zokwakha, ukusebenza kanye nokunakekelwa.izinkinga ezihlukahlukene okuhlangatshezwane nazo.Futhi lezi zinkinga azikho ngaphezu kwezidingo eziyisithupha zenethiwekhi ye-DCI (umkhawulokudonsa omkhulu, ukubambezeleka okuphansi, ukuminyana okuphezulu, ukuthunyelwa okusheshayo, ukusebenza okulula nokugcinwa, nokuthembeka okuphezulu):
1. I-bandwidth enkulu, inethiwekhi yokudlulisa i-DCI ayinazo izinhlobo ezicebile zama-granules njengama-opharetha, ama-bandwidth granules wenethiwekhi yokudlulisa ye-DCI alula, okwamanje asetshenziswa ngokuvamile i-10G noma i-100G, esikhathini esizayo i-200G/400G, njll., ngakho-ke asikho isidingo. ukukwenza ngomkhawulokudonsa omkhulu womkhawulokudonsa kwezinye izimbudumbudu.Ngenxa yokuthi ibanga lenethiwekhi yokudlulisa i-DCI ngokuvamile alulude kakhulu, kusetshenziswa uhlelo lwe-400G olusekelwe ku-200G PM-16QAM ukushintshwa kwe-dual-carrier, ibanga lokudlulisela ngaphandle kokudluliswa kukagesi lingaba amakhilomitha angu-500 (PM-64QAM is cishe amakhilomitha angama-200) , ukuze ukuhanjiswa komgogodla we-metro we-DCI kunganqunyelwe ibanga.
2. Ukubambezeleka okuphansi, izidingo zebhizinisi le-DCI, ikakhulukazi uma i-cloud computing isetshenziselwa ukuhlanganisa izinsiza kanye nezikhungo zedatha ezisebenzayo, ukubambezeleka kubalwa ezingeni le-microsecond, ngakho-ke isikhathi sokudluliswa kwedatha kufanele sibe sifushane ngangokunokwenzeka, sifisa ukweqa isivinini sokukhanya.Susa umsebenzi wokucubungula idatha ongadingekile futhi unciphise izindlela zokudlulisa isignali.Isibonelo, ngokususa umsebenzi we-SD-FEC osetshenziswa i-100G OTN, i-back-to-back eyodwa ingagcina ama-microsecond angu-200, futhi ukususa i-cross-level encapsulation ye-OTN kungasindisa amashumi ama-microseconds, futhi isebenzise ngokunengqondo i-topology ye-hubspoke ngezinsizakalo ezibalulekile. ukuqinisekisa indlela emfushane kakhulu.Yebo, ingase futhi ibambisane ne-MPLS ne-QOS ezingeni le-IP ukuze izame ukuqinisekisa ukuthi ukubambezeleka ezingeni lokudlulisela idatha nakho kungcono.
I-3.I-High density, i-U eyodwa, noma i-2U, ingafinyelela umkhawulokudonsa ofinyelela ku-T, ungqimba lwe-DWDM optical kanye nokwehlukanisa ungqimba lwesignali kagesi, ithuthukise isixhumi esibonakalayo sedivayisi, futhi inciphise usayizi wemojula ye-optical.Isibonelo, ukusetshenziswa kwamamojula we-QSFP28 optical kungaqinisekisa ukuthi ikhono lokufinyelela le-100G ledivayisi eyodwa lithuthukiswa kakhulu, futhi ukusetshenziswa kwamamojula we-CFP2 wokukhanya kwelanga ohlangothini lomugqa kungaqinisekisa ukuthi umkhawulokudonsa wokudlulisa wedivayisi yonke uthuthukisiwe, i-1U ingakwazi. kube 1.6T, 3.2T.Njengamanje, imikhiqizo eminingi ehlobene ivele emhlabeni, njenge-ADVA, i-coriant, i-ciena nezinye izinkampani.Vele, iHuawei yasekhaya iphinde yethule imikhiqizo ehlobene ye-902.Kodwa-ke, kuze kube sekuqedweni kwalesi sihloko, kubonakala sengathi ukuhlolwa kokufinyelela kwenethiwekhi koMnyango Wezimboni Nobuchwepheshe Bolwazi akukaqedwa.Ukuminyana okuphezulu kuzodala ukusetshenziswa kwamandla okuphezulu kanye nokuqeda ukushisa.Ngakho-ke, indlela yokuqala yokukhipha ukushisa kwe-OTN yomoya ongakwesokunxele nakwesokudla ngaphakathi nangaphandle, nomoya okhuphukayo naphansi ongaphakathi nangaphandle kufanele ulahlwe.
Izidingo zokupholisa idivayisi.
4. Ukuthunyelwa okusheshayo, kusetshenziswa irekhi emisiwe ye-IDC engu-19-intshi yamanje, efana nefomu lamaseva ajwayelekile, kusetshenziswa i-AC-220V ukuze kutholakale ugesi oqondile, okuqeda isidingo samandla nokuguqulwa kwekhabhinethi, nokuqaphela ukuthi izimpahla zingafakwa. amashalofu ngokushesha ngemva kokufika ekamelweni lekhompiyutha, futhi angalungiswa ngemva kokuxhuma ugesi.ibhizinisi, futhi wenze umsebenzi omuhle emsebenzini wokwamukela ojwayelekile ukuze uzuze ukuthunyelwa ngokushesha.
5. Ukusebenza nokugcinwa kalula, izidingo zemodeli yebhizinisi le-DCI, ibanga elinqamula izikhungo zedatha ngeke libe kude kakhulu, kanye nokuphathwa okuyinkimbinkimbi, i-OAM neminye imisebenzi akudingekile ukudlala indima enkulu kulesi simo, futhi ukucubungula okuyinkimbinkimbi nakho kuncishisiwe. Ithuthukisa ukusebenza kahle kokudluliswa kwedatha, ithuthukisa isikhathi sokucubungula idatha, futhi inezidingo eziphakeme zobuchwepheshe futhi ivaleke kakhulu.Ukuxhuma amasignali ngokuqondile nge-Ethernet kuqeda i-overhead eyinkimbinkimbi ye-OTN, ukuze onjiniyela benethiwekhi ye-IP bendabuko bakwazi ukusebenzisa futhi bagcine uhlelo lwe-DCI.Ngemva kokuhlanganisa izindawo ezintsha eziya enyakatho njengemodeli ye-YANG, i-REST API, ne-netconf, ukuphathwa kwemishini yokudlulisa ye-DCI kanye nokuphathwa kwemishini yenethiwekhi ye-IP kuthuthukiswa ngendlela efanayo, ukuze kwenziwe kangcono ukuphathwa kwenethiwekhi okusekelwe endaweni eyodwa okuhlangene.
6. Ukuthembeka okuphezulu, umzila owenziwe ngezinto eziningi kanye nobuchwepheshe bokuvikela abangaqapheli ungqimba olungaphezulu luzoqhubeka nokubamba iqhaza kunethiwekhi yokudlulisa i-DCI.Ukwehluleka ezingeni lesixhumanisi esiyisisekelo akufanele kube nomthelela kumasevisi ngaphandle uma kuphazamiseke ngokuphelele.Umbono noma umthelela, noma ngabe ukushintsha kokuvikela, i-jitter yesixhumanisi, ukwanda kokulibaziseka, njll.
