Ngokwalezi zici, cishe kunezixazululo ezimbili ezijwayelekile ze-DCI:
1. Sebenzisa okokusebenza okuhlanzekile kwe-DWDM, futhi usebenzise imojula ye-optical color + DWDM multiplexer/demultiplexer ekushintsheni.Endabeni ye-10G yesiteshi esisodwa, izindleko ziphansi kakhulu, futhi izinketho zomkhiqizo ziningi.Imoduli yokukhanya kombala we-10G isendlini Sekuvele kukhiqiziwe, futhi izindleko sezivele ziphansi kakhulu (empeleni, uhlelo lwe-10G DWDM lwaqala ukuthandwa eminyakeni embalwa edlule, kodwa ngokufika kwezinye izidingo ezinkulu zomkhawulokudonsa, lwalunayo. izoqedwa, futhi imojula yokukhanya kombala we-100G ibingakatholakali. Ivele.) Njengamanje, i-100G isanda kuqala ukuvela kumamojula ahlobene nombala we-China, futhi izindleko aziphansi ngokwanele, kodwa zizohlala zenza umnikelo onamandla. kunethiwekhi ye-DCI.
2. Sebenzisa okokusebenza kwe-OTN okuminyanisa okuphezulu, kungu-220V AC, okokusebenza okungu-19-intshi, ukuphakama okungu-1~2U, futhi ukuthunyelwa kulula kakhulu.Umsebenzi we-SD-FEC uvaliwe ukuze kuncishiswe ukubambezeleka, futhi ukuvikeleka komzila kusendlalelo sokubona kusetshenziselwa ukuthuthukisa ukuzinza, futhi isixhumi esibonakalayo esilawulekayo esiya enyakatho siphinde sithuthukise amandla okuthuthukisa imisebenzi yokunweba okokusebenza.Kodwa-ke, ubuchwepheshe be-OTN busagodliwe, futhi ukuphatha kusazoba nzima kakhulu.
Ukwengeza, lokho okwenziwa abakhi benethiwekhi ye-DCI yesigaba sokuqala njengamanje ikakhulukazi ukuqaqa inethiwekhi yokudlulisela ye-DCI, okuhlanganisa ukuqaqa i-optical ku-leyer 0 kanye nogesi kungqimba 1, kanye ne-NMS nemishini yehadiwe yabakhiqizi bendabuko. .ukuhlukanisa.Indlela evamile ukuthi okokusebenza komkhiqizi kagesi okucutshungulwa kufanele kusebenzisane nemishini yokubona yomkhiqizi ofanayo, futhi okokusebenza kwehadiwe kufanele kusebenzisane nesofthiwe yobunikazi yomkhiqizi ye-NMS yokuphatha.Le ndlela yendabuko inezinkinga ezimbalwa ezinkulu:
1. Ubuchwepheshe buvaliwe.Ngokombono, izinga le-optoelectronic lingahlukaniswa komunye nomunye, kodwa abakhiqizi bendabuko abahlukanisi ngamabomu ukuze balawule igunya lobuchwepheshe.
2. Izindleko zenethiwekhi yokudlulisa ye-DCI zigxile kakhulu kungqimba lokucubungula isignali kagesi.Izindleko zokuqala zokwakha zesistimu ziphansi, kodwa lapho umthamo unwetshwa, umenzi uzophakamisa intengo ngaphansi kosongo lokuhlukile kwezobuchwepheshe, futhi izindleko zokunwetshwa zizokwenyuka kakhulu.
3. Ngemuva kokuthi ungqimba olubonakalayo lwenethiwekhi yokudlulisa ye-DCI lusetshenzisiwe, lungasetshenziswa kuphela ungqimba lukagesi lomkhiqizi ofanayo.Izinga lokusetshenziswa kwezisetshenziswa zezinsiza liphansi, elingahambelani nesiqondiso sokuthuthukiswa kokuhlanganisa izinsiza zenethiwekhi, futhi alihambisani nokuhlelwa kwensiza ye-optical layer ehlanganisiwe.Isendlalelo se-optical ehlukanisiwe sitshalwa ngokuhlukile esigabeni sokuqala sokwakha, futhi asikhawulwanga ngokusetshenziswa kwesikhathi esizayo kwesistimu yongqimba olulodwa optical abakhiqizi abaningi, futhi sihlanganisa ukusebenzelana obheke enyakatho kongqimba olubonakalayo nobuchwepheshe be-SDN ukwenza ukuhlela isiqondiso sesiteshi. izinsiza ku-optical layer , Thuthukisa ukuguquguquka kwebhizinisi.
4. Imishini yenethiwekhi ixhuma ngaphandle komthungo nenkundla yokuphatha inethiwekhi yenkampani ye-inthanethi ngokuqondile ngesakhiwo sedatha ye-YANGmodel, esindisa ukutshalwa kwezimali kwentuthuko yesikhulumi sokuphatha futhi iqede isoftware ye-NMS enikezwe umenzi, ethuthukisa ukusebenza kahle kokuqoqwa kwedatha kanye ukuphathwa kwenethiwekhi.ukusebenza kahle kokuphatha.
Ngakho-ke, i-optoelectronic decoupling iyindlela entsha yokuthuthukiswa kwenethiwekhi yokudlulisela ye-DCI.Esikhathini esizayo esibonakalayo, ungqimba lwe-optical lwenethiwekhi yokudlulisela ye-DCI ingaba ubuchwepheshe be-SDN obuhlanganiswe i-ROADM+ isikhombimsebenzisi esisenyakatho naseningizimu, futhi isiteshi singavulwa, sihlelwe futhi sitholakale ngokuzenzakalelayo.Kuzokwazi ukusebenzisa amadivaysi kagesi axubile abakhiqizi, noma ukusetshenziswa okuxubile kwe-Ethernet interface kanye ne-OTN kusistimu efanayo yokubona.Ngaleso sikhathi, ukusebenza kahle komsebenzi mayelana nokwandiswa noshintsho lwesistimu kuzothuthukiswa kakhulu, futhi ungqimba olubonakalayo luzosetshenziswa.Kulula ukuhlukanisa, ukuphathwa kwe-logic yenethiwekhi kucacile, futhi izindleko zizoncishiswa kakhulu.
Ku-SDN, isisekelo esiyinhloko ukuphatha kanye nokwabiwa kwezinsiza zenethiwekhi.Ngakho-ke, yiziphi izinsiza zenethiwekhi yokudlulisa ye-DWDM ezingaphathwa kunethiwekhi yamanje yokudlulisa ye-DCI?
Kukhona iziteshi ezintathu, izindlela, kanye nomkhawulokudonsa (imvamisa).Ngakho-ke, ukukhanya ekusebenzisaneni kokukhanya + IP empeleni kwenziwa eduze nokuphathwa nokusabalalisa lawa maphuzu amathathu.
Amashaneli e-IP ne-DWDM anqanyuliwe, ngakho-ke uma ubudlelwano obuhambisanayo phakathi kwesixhumanisi esinengqondo se-IP nesiteshi se-DWDM bulungiswa ekuqaleni, futhi ubudlelwano obuhambisanayo phakathi kwesiteshi ne-IP budinga ukulungiswa ngokuhamba kwesikhathi, ungasebenzisa i-OXC. Indlela isetshenziselwa ukwenza ukushintsha kwesiteshi okusheshayo ezingeni le-millisecond, okungenza isendlalelo se-IP singazi.Ngokuphathwa kwe-OXC, ukuphathwa kwensiza okumaphakathi kwesiteshi sokudlulisela kusayithi ngalinye kungenziwa, ukuze kusetshenziswane ne-SDN yebhizinisi.
Ukulungiswa kokuxhuma kwesiteshi esisodwa ne-IP kuyingxenye encane kuphela.Uma ucabanga ukulungisa umkhawulokudonsa ngenkathi ulungisa isiteshi, ungakwazi ukuxazulula inkinga yokulungisa izidingo zomkhawulokudonsa wezinsizakalo ezahlukene ngezikhathi ezahlukene.Thuthukisa kakhulu izinga lokusetshenziswa komkhawulokudonsa owakhiwe.Ngakho-ke, ngenkathi kuxhunyanwa ne-OXC ukulungisa isiteshi, kuhlanganiswe ne-multiplexer kanye ne-demultiplexer yobuchwepheshe begridi obuguquguqukayo, isiteshi esisodwa asisenabo ubude begagasi obumaphakathi obugxilile, kodwa sisivumela ukuthi simboze ibanga lokuvama okwehlayo, ukuze sifinyelele ukulungiswa Okuguquguqukayo usayizi womkhawulokudonsa.Ngaphezu kwalokho, esimweni sokusebenzisa izinsizakalo eziningi ku-topology yenethiwekhi, izinga lokusebenzisa imvamisa yohlelo lwe-DWDM lingathuthukiswa ngokwengeziwe, futhi izinsiza ezikhona zingasetshenziswa ekugcwaliseni.
Ngamandla okuphatha aguqukayo amabili okuqala, ukuphathwa kwendlela yenethiwekhi yokudlulisa kungasiza yonke i-topology yenethiwekhi ukuthi ibe nokuzinza okuphezulu.Ngokwezici zenethiwekhi yokudlulisela, indlela ngayinye inezinsiza zesiteshi sokudlulisa ezizimele, ngakho kubaluleke kakhulu ukuphatha nokwaba iziteshi endleleni ngayinye yokudlulisela ngendlela ebumbene, okuzohlinzeka ngokukhetha indlela efanele yezinsizakalo zezindlela eziningi , futhi andise ukusetshenziswa kwezinsiza zesiteshi kuzo zonke izindlela.Njengaku-ASON, igolide, isiliva nethusi kuhlukaniswa ngamasevisi ahlukene ukuze kuqinisekiswe ukuzinza kwezinga eliphezulu lezinsizakalo.
Isibonelo, kunenethiwekhi yendandatho eyakhiwe izikhungo ezintathu zedatha A, B, kanye no-C. Kukhona isevisi ye-S1 (njengesevisi yedatha ye-intranethi enkulu), kusukela ku-A kuya ku-B kuya ku-C, ethatha amagagasi angu-1~5 ale nethiwekhi yendandatho, igagasi ngalinye linomkhawulokudonsa we-100G, futhi isikhawu semvamisa yi-50GHz;kukhona isevisi ye-S2 (isevisi yenethiwekhi yangaphandle), Kusukela ku-A kuya ku-B kuya ku-C, amagagasi angu-6 ~ 9 ale nethiwekhi yendandatho asetshenziswa, igagasi ngalinye linomkhawulokudonsa we-100G, futhi imvamisa ye-50GHz.
Ezikhathini ezijwayelekile, lolu hlobo lomkhawulokudonsa nokusetshenziswa kwesiteshi lungahlangabezana nesidingo, kodwa lapho ngezinye izikhathi, ngokwesibonelo, isikhungo sedatha esisha sengezwa, futhi ibhizinisi lidinga ukuthutha isizindalwazi ngesikhathi esifushane, khona-ke isidingo somkhawulokudonsa we-intranet lesi sikhathi sizoba Siphindeke kabili, umkhawulokudonsa wokuqala we-500G (5 100G), manje udinga umkhawulokudonsa we-2T.Khona-ke iziteshi ezingeni lokudlulisela zingabalwa kabusha, futhi iziteshi ezinhlanu ze-400G zifakwe kungqimba lwamagagasi.Isikhawu samafrikhwensi sesiteshi ngasinye esingu-400G siyashintshwa sisuka kwesangempela esingu-50GHz siye ku-75GHz.Nge-ROADM yokugaya eguquguqukayo kanye ne-multiplexer/demultiplexer, yonke Indlela esezingeni lokudlulisela, ngakho lezi ziteshi ezinhlanu zisebenzisa izinsiza ze-spectrum ze-375GHz.Ngemuva kokuthi izinsiza ezingeni lokudlulisela sezilungile, lungisa i-OXC ngokusebenzisa isiteji sokuphatha esimaphakathi, futhi ulungise iziteshi zokudlulisela ezisetshenziswa amaza okuqala angu-1-5 wezimpawu zesevisi ye-100G ku-5 esanda kulungiselelwa ngokulibaziseka kwezinga le-millisecond Isevisi ye-400G isiteshi siyakhuphuka, ukuze umsebenzi wokulungiswa okuguquguqukayo komkhawulokudonsa kanye nesiteshi ngokwezidingo zesevisi ye-DCI uqedwe, ongenziwa ngesikhathi sangempela.Yiqiniso, izixhumi zenethiwekhi zamadivayisi we-IP zidinga ukusekela i-100G/400G izinga eliguquguqukayo kanye nemisebenzi yokulungiswa kwesignali ye-optical (wavelength), okungeke kube yinkinga.
Mayelana nobuchwepheshe benethiwekhi ye-DCI, umsebenzi ongaqedwa ngokudluliswa usezingeni eliphansi kakhulu.Ukuze kuzuzwe inethiwekhi ye-DCI ehlakaniphe kakhulu, idinga ukwenziwa kanye ne-IP.Isibonelo, sebenzisa i-MP-BGP EVPN+VXLAN ku-intranethi ye-IP ye-DCI ukuze usebenzise ngokushesha inethiwekhi ye-layer 2 kuwo wonke ama-DC, engahambisana kakhulu namadivayisi enethiwekhi akhona futhi ihlangabezane nezidingo zemishini ebonakalayo eqashiwe ukuze ihambe kalula kuwo wonke ama-DC.;Sebenzisa umzila wengxenye kunethiwekhi yangaphandle ye-IP ye-DCI ukwenza ukuhlela umzila wethrafikhi ngokusekelwe ekuhlukaniseni ibhizinisi lomthombo, ukuhlangabezana nezimfuneko zokubonwa kwethrafikhi ye-cross-DC, ukubuyiselwa komzila osheshayo, kanye nokusetshenziswa komkhawulokudonsa ophezulu;inethiwekhi yokudlulisela engaphansi ibambisana nesistimu ye-OXC enezinhlangothi eziningi, Uma iqhathaniswa ne-ROADM evamile yamanje, ingakwazi ukubona umsebenzi wokuhlela wendlela yesevisi ehlanjululwe kahle;ukusetshenziswa kobuchwepheshe bokuguqulwa kwe-wavelength okungewona ugesi kungaxazulula inkinga yokuhlukaniswa kwezinsiza ze-spectrum yesiteshi.Ukuhlanganiswa kwezinsiza zesendlalelo esiphezulu neziphansi zokuphathwa kwebhizinisi nokusetshenziswa, ukuthunyelwa okuvumelana nezimo, kanye nokusetshenziswa kwezinsiza okuthuthukisiwe kuzoba yisiqondiso esingenakugwenywa esikhathini esizayo.Njengamanje, ezinye izinkampani ezinkulu zasekhaya ziyayinaka le ndawo, kanti ezinye izinkampani ezikhethekile eziqalayo sezivele zenza ucwaningo nokuthuthukiswa kwemikhiqizo yezobuchwepheshe ehlobene.Ngiyethemba ukubona izixazululo eziphelele ezihlobene emakethe kulo nyaka.Mhlawumbe esikhathini esizayo esiseduze, i-OTN izophinde inyamalale kumanethiwekhi esigaba senethiwekhi, kusale i-DWDM kuphela.
