3 Ukuphatha Ukumisa
Phakathi nokucushwa kwesiteshi, ukucushwa kwesevisi, ukumiswa kwesixhumanisi esiphusile sesendlalelo esibonakalayo, kanye nokuxhumanisa ukucushwa kwemephu ye-virtual topology kuyadingeka.Uma isiteshi esisodwa singase simiswe ngendlela yokuvikela, ukumiswa kwesiteshi ngalesi sikhathi kuzoba nzima kakhulu, futhi nokuphathwa kokuhlelwa okulandelayo nakho kuzoba nzima kakhulu.Kudingeka ithebula lesevisi elizinikele ukuze nje ulawule ukuqondiswa kwesiteshi, futhi izikhombisi-ndlela zebhizinisi kufanele zihlukaniswe etafuleni, kusetshenziswa imigqa eqinile nedeshi.Lapho ukuxhumana phakathi kweziteshi ze-OTN nezixhumanisi ze-IP kulawulwa, ikakhulukazi esimweni sokuvikelwa kwe-OTN, isixhumanisi esisodwa se-IP sidinga ukuhambisana namashaneli amaningi e-OTN.Ngalesi sikhathi, inani lokuphatha liyakhuphuka futhi nokuphatha kuyinkimbinkimbi, okwandisa nokuphathwa kwamatafula e-excel.Izidingo, ukuphatha ngokuphelele zonke izakhi zebhizinisi, kuze kufike ku-15. Uma unjiniyela efuna ukuphatha isixhumanisi esithile, udinga ukuthola ifomu le-excel, bese eya ku-NMS yomkhiqizi ukuze athole okuhambisanayo, bese enza umsebenzi. abaphathi.Lokhu kudinga ukuvumelanisa kolwazi nhlangothi zombili.Njengoba inkundla ye-NMS ye-OTN kanye ne-excel eyenziwe unjiniyela kuyidatha emibili eyenziwe umuntu, kulula ukuthi ulwazi lungavumelani.Noma yiliphi iphutha lizokwenza ukuthi ulwazi lwebhizinisi lungahambisani nobudlelwano bangempela.Ngokuhambisanayo, kungase kuthinte ibhizinisi lapho lishintsha futhi lilungiswa.Ngakho-ke, idatha yemishini yomkhiqizi iqoqwa endaweni yokuphatha ngokusebenzisa isikhombikubona esisenyakatho, bese imininingwane yesixhumanisi se-IP ifaniswe kule nkundla, ukuze ulwazi lulungiswe ngokuzenzakalelayo ngokuvumelana nezinguquko zesevisi yenethiwekhi ekhona. , futhi nokuphathwa kolwazi okumaphakathi kuyaqinisekiswa.kanye nomthombo owodwa wokunemba wokuqinisekisa ukunemba kolwazi lokuphatha ukucushwa.
Lapho ulungiselela ukunikezwa kwesevisi ye-OTN, lungiselela incazelo yolwazi yesixhumi esibonakalayo ngasinye, bese uqoqa ulwazi lwe-OTN ngoxhumano oluya enyakatho olunikezwa i-OTN NMS, bese ubhanqa incazelo efanele nolwazi lwembobo oluqoqwe idivayisi ye-IP ngoxhumano oluya enyakatho.Ukuphathwa okusekelwe kunkundla yeziteshi ze-OTN nezixhumanisi ze-IP kususa isidingo sokubuyekezwa kolwazi okwenziwa ngesandla.
Ngokusebenzisa inethiwekhi yokudlulisa ye-DCI, zama ukugwema ukusetshenziswa kokucushwa kwesevisi kagesi yokuxhumanisa.Le ndlela iyinkimbinkimbi kakhulu kumqondo wokuphatha, futhi ayisebenzi kumodeli yenethiwekhi ye-DCI.Kungagwenywa kusukela ekuqaleni kwe-DCI design.
4 Ukuphathwa kwe-alamu
Ngenxa yokuphatha okuyinkimbinkimbi kwe-OTN, ukuqapha isignali phakathi nokudluliswa kwebanga elide, nokuphindaphinda nokuzalela izinhlayiya zesevisi ezihlukene, iphutha lingabika inqwaba noma amakhulu emilayezo ye-alamu.Nakuba umkhiqizi ehlukanise ama-alamu ngamaleveli amane, futhi i-alamu ngayinye inegama elihlukile, isaxaka ngokwedlulele ngokombono wokusebenza nokunakekela kukanjiniyela, futhi idinga abasebenzi abanolwazi ukucacisa imbangela yokwehluleka kwasekuqaleni.Umsebenzi wokuthumela iphutha wemishini yendabuko ye-OTN ikakhulukazi isebenzisa imodemu ye-SMS noma i-imeyili push, kodwa imisebenzi emibili ikhethekile ukuhlanganiswa nenkundla ekhona yokulawula i-alamu yenethiwekhi yesistimu eyisisekelo yenkampani ye-inthanethi, futhi izindleko zokuthuthukiswa okuhlukene ziphezulu, ngakho izidingo ezengeziwe. okumele kwenziwe.Ukusebenzelana okujwayelekile okuya enyakatho kuqoqa ulwazi lwe-alamu, kunwebe imisebenzi kuyilapho kugcinwa izinkundla ezifanele zenkampani ezikhona, bese iphushela i-alamu kunjiniyela wokusebenza nokulungisa.
Ngakho-ke, kubasebenzi bokusebenza nokulungisa, kuyadingeka ukuvumela ipulatifomu iguqule ngokuzenzakalelayo imininingwane ye-alamu ekhiqizwe iphutha le-OTN, bese uthola imininingwane.Ngakho-ke, qala usethe ukuhlukaniswa kwe-alamu ku-OTN NMS, bese wenza umsebenzi wokuthumela nokuhlola endaweni yokugcina yokuphatha ulwazi lwe-alamu.Indlela ye-alamu ye-OTN evamile ukuthi i-NMS izosetha futhi isunduze zonke izinhlobo zokuqala nezesibili zama-alamu endaweni yokuphatha ulwazi lwe-alamu, bese isiteji sizohlaziya ulwazi lwe-alamu lokuphazamiseka kwesevisi eyodwa, okuyinhloko I-alamu yokuphazamiseka kwendlela yokubona. ulwazi kanye (uma lukhona) ulwazi lokushintshwa kwe-alamu luphushelelwa kunjiniyela wokusebenza nokunakekela.Ulwazi oluthathu olungenhla lungase lusetshenziselwe ukuhlonza iphutha nokucubungula.Lapho usetha ukwamukela, ungasetha izilungiselelo zezaziso zocingo zama-alamu amakhulu afana nokwehluleka kwesignali esiyinhlanganisela okwenzeka kuphela lapho kuphulwa ama-optical fibers, njengokulandelayo:
Incazelo yesiShayina ye-alamu
I-alamu Incazelo yesiNgisi Uhlobo lwe-alamu Ukuqina kanye nomkhawulo

I-interface ebheke enyakatho ye-NMS, njengesixhumi esibonakalayo se-XML okwamanje esisekelwa i-Huawei ne-ZTE Alang, nayo ivame ukusetshenziselwa ukusunduza ulwazi lwe-alamu.
5 Ukuphathwa Kokusebenza
Ukuzinza kwesistimu ye-OTN kuncike kakhulu kudatha yokusebenza yezici ezihlukahlukene zesistimu, njengokuphathwa kwamandla okubona kwe-trunk fibre, ukuphathwa kwamandla okukhanya kwesiteshi ngasinye kusiginali ephindwe kabili, kanye nokuphathwa kwemajini ye-OSNR yesistimu.Lokhu okuqukethwe kufanele kwengezwe kuphrojekthi yokuqapha yesistimu yenethiwekhi yenkampani, ukuze ukwazi ukusebenza kwesistimu nganoma yisiphi isikhathi, futhi nokwandisa ukusebenza ngesikhathi ukuze kuqinisekiswe ukuzinza kwenethiwekhi.Ukwengeza, ukusebenza kwefayibha yesikhathi eside nokuqapha ikhwalithi nakho kungasetshenziswa ukuthola izinguquko emzileni wefayibha, ukuvimbela abanye abahlinzeki befayibha ekuguquleni i-fiber routing ngaphandle kwesaziso, okuholela ezindaweni eziyizimpumputhe ekusebenzeni nasekulungisweni, kanye nokuvela kwengozi ye-fiber routing.Yiqiniso, lokhu kudinga inani elikhulu ledatha yokuqeqeshwa kwemodeli, ukuze ukutholakala kwezinguquko zomzila kube nembe kakhulu.
6. Ukuphathwa kwe-DCN
I-DCN lapha isho inethiwekhi yokuxhumana yabaphathi yempahla ye-OTN, enesibopho sokwakheka kwenethiwekhi yokuphathwa kwento ngayinye yenethiwekhi ye-OTN.Inethiwekhi ye-OTN izophinde ithinte isikali nobunkimbinkimbi benethiwekhi ye-DCN.Ngokuvamile, kunezindlela ezimbili zenethiwekhi ye-DCN:
1. Qinisekisa ama-NE esango elisebenzayo nelibekwe eceleni kuyo yonke inethiwekhi ye-OTN.Amanye ama-NE angewona amasango angama-NE ajwayelekile.Amasiginali okuphatha awo wonke ama-NE ajwayelekile afinyelela kuma-NE wesango asebenzayo nawe-standby ngesiteshi se-OSC ngaphesheya kwesendlalelo se-OTS ku-OTN, bese-ke Xhuma kunethiwekhi ye-IP lapho i-NMS ikhona.Le ndlela inganciphisa ukuthunyelwa kwezinto zenethiwekhi kunethiwekhi ye-IP lapho i-NMS ikhona, futhi isebenzise i-OTN ngokwayo ukuxazulula inkinga yokuphatha inethiwekhi.Kodwa-ke, uma i-trunk fiber iphazamiseka, izici zenethiwekhi ezikude ezihambisanayo nazo zizothinteka futhi ngeke zilawuleke.
2. Zonke izici zenethiwekhi yenethiwekhi ye-OTN zilungiswa njengama-elementi enethiwekhi yesango, futhi ingxenye ngayinye yenethiwekhi yesango ixhumana nenethiwekhi ye-IP lapho i-NMS itholakala khona ngokuzimela ngaphandle kokudlula kusiteshi se-OSC.Lokhu kuqinisekisa ukuthi ukuxhumana kokuphatha kwezakhi zenethiwekhi akuthintwa ukuphazanyiswa kwe-fiber optical main, futhi izakhi zenethiwekhi zisengaphathwa ukude, zonke zixhunywe kunethiwekhi ye-IP, kanye nezindleko zokusebenza nokugcinwa kwendabuko. Izisebenzi zenethiwekhi ye-IP nazo zizoncishiswa.
Ekuqaleni kokwakhiwa kwenethiwekhi ye-DCN, ukuhlelwa kwesici senethiwekhi nokwabiwa kwekheli le-IP kufanele kwenziwe.Ikakhulukazi, iseva yokuphatha inethiwekhi kufanele ihlukaniswe kwamanye amanethiwekhi ngangokunokwenzeka lapho isetshenziswa.Uma kungenjalo, kuzoba nezixhumanisi eziningi kakhulu ze-mesh kunethiwekhi kamuva, futhi i-jitter yenethiwekhi izoba evamile ngesikhathi sokulungiswa, futhi izici zenethiwekhi ezijwayelekile ngeke zixhumeke.Izinkinga ezifana nesici senethiwekhi yesango zizovela, futhi ikheli lenethiwekhi yokukhiqiza kanye nekheli lenethiwekhi ye-DCN kuzophinda kusetshenziswe, okuzothinta inethiwekhi yokukhiqiza.
