3 Ukuphathwa Kokucushwa
Ngesikhathi sokucushwa kwesiteshi, ukucushwa kwesevisi, ukucushwa kwesixhumanisi esinengqondo se-optical layer, kanye nokucushwa kwemephu ye-topology ebonakalayo yesixhumanisi kuyadingeka. Uma isiteshi esisodwa singase silungiselelwe ngendlela yokuvikela, ukucushwa kwesiteshi ngalesi sikhathi kuzoba nzima kakhulu, futhi ukuphathwa kokucushwa okulandelayo kuzoba nzima kakhulu. Ithebula lesevisi elizinikele liyadingeka ukuze kuphathwe ukuqondiswa kwesiteshi, futhi izikhombisi-ndlela zebhizinisi kumele zihlukaniswe etafuleni, kusetshenziswa imigqa eqinile nenemigqa egqamile. Lapho ukuxhumana phakathi kweziteshi ze-OTN nezixhumanisi ze-IP kuphathwa, ikakhulukazi esimweni sokuvikelwa kwe-OTN, isixhumanisi esisodwa se-IP sidinga ukuhambisana neziteshi eziningi ze-OTN. Ngalesi sikhathi, inani lokuphatha liyakhuphuka futhi ukuphathwa kuyinkimbinkimbi, okwandisa nokuphathwa kwamathebula e-excel. Izidingo, ukuphatha ngokuphelele zonke izinto zebhizinisi, kufika ku-15. Lapho unjiniyela efuna ukuphatha isixhumanisi esithile, udinga ukuthola ifomu le-excel, bese eya ku-NMS yomenzi ukuthola okuhambisanayo, bese enza ukuphathwa kokusebenza. Lokhu kudinga ukuvumelanisa ulwazi kuzo zombili izinhlangothi. Njengoba ipulatifomu ye-NMS ye-OTN kanye ne-excel eyenziwe unjiniyela kuyidatha emibili eyenziwe ngumuntu, kulula ukuthi ulwazi lungavumelani. Noma yiliphi iphutha lizobangela ukuthi ulwazi lwebhizinisi lungahambisani nobudlelwano bangempela. Ngokufanayo, kungathinta ibhizinisi lapho kushintsha futhi kulungiswa. Ngakho-ke, idatha yemishini yomenzi iqoqwa kwipulatifomu yokuphatha ngokusebenzisa isikhombikubona esiya enyakatho, bese ulwazi lwesixhumanisi se-IP lufaniswa kule pulatifomu, ukuze ulwazi lulungiswe ngokuzenzakalelayo ngokuya ngezinguquko zesevisi yenethiwekhi ekhona, futhi ukuphathwa kolwazi okuphakathi kuqinisekiswe. kanye nomthombo owodwa wokunemba ukuqinisekisa ukunemba kolwazi lokuphathwa kokucushwa.
Uma ulungiselela ukuhlinzekwa kwesevisi ye-OTN, lungisa incazelo yolwazi lwesixhumi ngasinye, bese uqoqa ulwazi lwe-OTN ngesixhumi esibheke enyakatho esinikezwe yi-OTN NMS, bese ubhangqa incazelo efanele nolwazi lwembobo oluqoqwe yidivayisi ye-IP ngesixhumi esibheke enyakatho. Ukuphathwa kweziteshi ze-OTN nezixhumanisi ze-IP okusekelwe epulatifomu kuqeda isidingo sokubuyekezwa kolwazi ngesandla.
Ukuze usebenzise inethiwekhi yokudlulisa ye-DCI, zama ukugwema ukusebenzisa ukucushwa kwesevisi yokuxhumanisa kagesi. Le ndlela iyinkimbinkimbi kakhulu ngokomqondo wokuphatha, futhi ayisebenzi kumodeli yenethiwekhi ye-DCI. Ingagwenywa kusukela ekuqaleni komklamo we-DCI.
4 Ukuphathwa kwe-alamu
Ngenxa yokuphathwa okuyinkimbinkimbi kwe-OTN, ukuqapha isignali ngesikhathi sokudlulisa ibanga elide, kanye nokuhlanganisa nokwakha izinhlayiya zesevisi ezahlukene, iphutha lingabika imiyalezo eminingi noma engamakhulu ye-alamu. Nakuba umenzi ehlukanise ama-alamu ngezigaba ezine, futhi i-alamu ngayinye inegama elihlukile, iseyinkimbinkimbi kakhulu ngokombono wokusebenza nokugcinwa konjiniyela, futhi idinga abasebenzi abanolwazi ukuthola imbangela yokwehluleka kwasekuqaleni. Umsebenzi wokuthumela amaphutha wemishini yendabuko ye-OTN usebenzisa kakhulu imodemu ye-SMS noma i-imeyili push, kodwa imisebenzi emibili ikhethekile ekuhlanganisweni nepulatifomu yokuphathwa kwe-alamu yenethiwekhi ekhona ohlelweni oluyisisekelo lwenkampani ye-inthanethi, futhi izindleko zokuthuthukiswa okuhlukile ziphezulu, ngakho-ke kudingeka kwenziwe okwengeziwe. I-interface ejwayelekile eya enyakatho iqoqa ulwazi lwe-alamu, yandisa imisebenzi ngenkathi igcina amapulatifomu akhona enkampani afanele, bese isunduza i-alamu kunjiniyela wokusebenza nokulungisa.
Ngakho-ke, kubasebenzi bokusebenza nokulungisa, kubalulekile ukuvumela ipulatifomu ihlanganise ngokuzenzakalelayo ulwazi lwe-alamu olukhiqizwe yiphutha le-OTN, bese uthola ulwazi. Ngakho-ke, qala usethe ukuhlukaniswa kwe-alamu ku-OTN NMS, bese wenza umsebenzi wokuthumela nokuhlola epulatifomu yokugcina yokuphathwa kolwazi lwe-alamu. Indlela ejwayelekile ye-alamu ye-OTN ukuthi i-NMS izosetha futhi isunduze zonke izinhlobo zokuqala nezesibili zama-alamu epulatifomu yokuphathwa kolwazi lwe-alamu, bese ipulatifomu izohlaziya ulwazi lwe-alamu lokuphazamiseka kwesevisi eyodwa, okuyinhloko Ulwazi lwe-alamu yokuphazamiseka kwendlela yokukhanya kanye (uma lukhona) ulwazi lwe-alamu yokushintsha ukuvikela lusunduzwa kunjiniyela wokusebenza nokulungisa. Ulwazi olungenhla oluthathu lungasetshenziswa ekuxilongweni nasekucutshungulweni kwamaphutha. Lapho usetha ukwamukela, ungasetha izilungiselelo zesaziso sefoni zama-alamu amakhulu njengokwehluleka kwesignali ehlanganisiwe okwenzeka kuphela lapho imicu yokukhanya iphukile, njengokulandelayo:
Incazelo ye-alamu yesiShayina
Incazelo ye-alamu yesiNgisi Uhlobo lwe-alamu Ubunzima kanye nokulinganiselwa
Ukulahlekelwa Kwesignali Yesigcawu Sokulayisha I-OMS_LOS_P I-Alamu Yokuxhumana Ebalulekile (FM)
Okungenayo/Okuphumayo Ukulahlekelwa Kwesignali Ehlanganisiwe I-MUT_LOS I-Alamu Yokuxhumana Ephuthumayo (FM)
Ukulahlekelwa yi-OTS Payload
I-alamu Yokuxhumana Ebalulekile Yesignali ye-OTS_LOS_P (FM)
Isibonakaliso Sokulahlekelwa Komthwalo We-OTS I-OTS_PMI I-Alarm Yokuxhumana Ephuthumayo (FM)
Isixhumi esibonakalayo esiya enyakatho se-NMS, njengesixhumi esibonakalayo se-XML esisekelwa yi-Huawei ne-ZTE Alang njengamanje, sivame ukusetshenziswa ukusunduza ulwazi lwe-alamu.
5 Ukuphathwa Kokusebenza
Ukuqina kohlelo lwe-OTN kuncike kakhulu kudatha yokusebenza kwezici ezahlukahlukene zohlelo, njengokuphathwa kwamandla okukhanya kwe-trunk fiber, ukuphathwa kwamandla okukhanya kwesiteshi ngasinye kusignali ehlanganisiwe, kanye nokuphathwa kwe-margin yesistimu ye-OSNR. Lokhu okuqukethwe kufanele kwengezwe kuphrojekthi yokuqapha uhlelo lwenethiwekhi yenkampani, ukuze kwaziwe ukusebenza kohlelo nganoma yisiphi isikhathi, futhi kwenziwe ngcono ukusebenza ngesikhathi ukuqinisekisa ukuzinza kwenethiwekhi. Ngaphezu kwalokho, ukusebenza kwe-fiber yesikhathi eside kanye nokuqapha ikhwalithi nakho kungasetshenziswa ukuthola izinguquko ekuqondisweni kwe-fiber, kuvimbele abanye abahlinzeki be-fiber ekushintsheni umzila we-fiber ngaphandle kwesaziso, okuholela ezindaweni ezingaboni kahle ekusebenzeni nasekugcinweni, kanye nokuvela kwengozi yomzila we-fiber. Yiqiniso, lokhu kudinga inani elikhulu ledatha yokuqeqeshwa kwemodeli, ukuze ukutholakala kwezinguquko zomzila kube nembaba kakhulu.
6. Ukuphathwa kwe-DCN
I-DCN lapha ibhekisela kunethiwekhi yokuxhumana yokuphatha yemishini ye-OTN, ephethe isakhiwo senethiwekhi sokuphathwa kwengxenye ngayinye yenethiwekhi ye-OTN. Inethiwekhi ye-OTN izophinde ithinte ubukhulu kanye nobunzima benethiwekhi ye-DCN. Ngokuvamile, kunezindlela ezimbili zenethiwekhi ye-DCN:
1. Qinisekisa ama-NE esango asebenzayo nalindile kuyo yonke inethiwekhi ye-OTN. Amanye ama-NE angewona amasango angama-NE ajwayelekile. Izimpawu zokuphatha zawo wonke ama-NE ajwayelekile zifinyelela ama-NE esango asebenzayo nalindile ngesiteshi se-OSC ngaphesheya kwesendlalelo se-OTS ku-OTN, bese uxhuma kunethiwekhi ye-IP lapho i-NMS itholakala khona. Le ndlela inganciphisa ukuthunyelwa kwezinto zenethiwekhi kunethiwekhi ye-IP lapho i-NMS itholakala khona, futhi isebenzise i-OTN ngokwayo ukuxazulula inkinga yokuphathwa kwenethiwekhi. Kodwa-ke, uma i-trunk fiber iphazamiseka, izinto zenethiwekhi ezikude ezihambisanayo nazo zizothinteka futhi ngeke ziphathwe.
2. Zonke izakhi zenethiwekhi zenethiwekhi ye-OTN zihlelwe njengezakhi zenethiwekhi yesango, futhi isakhi ngasinye senethiwekhi yesango sixhumana nenethiwekhi ye-IP lapho i-NMS itholakala khona ngokuzimela ngaphandle kokudlula esiteshini se-OSC. Lokhu kuqinisekisa ukuthi ukuxhumana kokuphathwa kwezakhi zenethiwekhi akuthinteki ukuphazamiseka kwefayibha eyinhloko ye-optical, futhi izakhi zenethiwekhi zisengaphathwa kude, zonke ezixhunywe kunethiwekhi ye-IP, futhi izindleko zokusebenza nokugcinwa kwabasebenzi benethiwekhi ye-IP yendabuko nazo zizoncishiswa.
Ekuqaleni kokwakhiwa kwenethiwekhi ye-DCN, ukuhlela izakhi zenethiwekhi kanye nokwabiwa kwamakheli e-IP kufanele kwenziwe. Ikakhulukazi, iseva yokuphathwa kwenethiwekhi kufanele ihlukaniswe kwamanye amanethiwekhi ngangokunokwenzeka lapho isetshenziswa. Ngaphandle kwalokho, kuzoba nezixhumanisi eziningi kakhulu ze-mesh kunethiwekhi kamuva, futhi i-jitter yenethiwekhi izoba evamile ngesikhathi sokulungiswa, futhi izakhi zenethiwekhi ezijwayelekile ngeke zixhunywe. Izinkinga ezifana nesakhi senethiwekhi yesango zizovela, futhi ikheli lenethiwekhi yokukhiqiza kanye nekheli lenethiwekhi ye-DCN kuzosetshenziswa kabusha, okuzothinta inethiwekhi yokukhiqiza.
