3 Ulawulo loBume
Ngexesha loqwalaselo lwetshaneli, uqwalaselo lwenkonzo, uqwalaselo lwekhonkco elicwangcisiweyo le-optical layer, kunye noqwalaselo lwemephu ye-link virtual topology ziyafuneka. Ukuba itshaneli enye inokulungiswa ngendlela yokukhusela, uqwalaselo lwetshaneli ngeli xesha luya kuba nzima ngakumbi, kwaye ulawulo loqwalaselo olulandelayo luya kuba nzima ngakumbi. Itheyibhile yenkonzo ezinikeleyo iyafuneka ukuze kulawulwe ulwalathiso lwetshaneli, kwaye imiyalelo yeshishini kufuneka yahlulwe kwitheyibhile, kusetyenziswa imigca eqinileyo neqhekekileyo. Xa unxibelelwano phakathi kwetshaneli ze-OTN kunye neekhonkco ze-IP lulawulwa, ingakumbi kwimeko yokhuselo lwe-OTN, ikhonkco elinye le-IP kufuneka lihambelane neetshaneli ezininzi ze-OTN. Ngeli xesha, inani lolawulo liyakhula kwaye ulawulo luyinkimbinkimbi, nto leyo ekwandisa ulawulo lweetafile ze-excel. Iimfuno, zokulawula ngokupheleleyo zonke izinto zeshishini, ukuya kuthi ga kwi-15. Xa injineli ifuna ukulawula ikhonkco elithile, kufuneka ifumane ifomu ye-excel, ize emva koko iye kwi-NMS yomenzi ukuze ifumane ehambelanayo, ize emva koko yenze ulawulo lokusebenza. Oku kufuna ulungelelwaniso lolwazi kumacala omabini. Ekubeni iqonga le-NMS le-OTN kunye ne-excel eyenziwe yinjineli ziyidatha ezimbini ezenziwe ngumntu, kulula ukuba ulwazi lungabi lulungelelwaniso. Nayiphi na impazamo iya kubangela ukuba ulwazi lweshishini lungangqinelani nolwalamano lokwenyani. Ngokufanayo, inokuchaphazela ishishini xa litshintsha kwaye lilungisa. Ke ngoko, idatha yezixhobo zomenzi iqokelelwa kwiqonga lolawulo nge-interface eya emantla, kwaye emva koko ulwazi lwekhonkco le-IP luhambelana kweli qonga, ukuze ulwazi luhlengahlengiswe ngokuzenzekelayo ngokweenguqu zenkonzo yenethiwekhi ekhoyo, kwaye ulawulo oluphakathi lolwazi luqinisekiswe. kunye nomthombo omnye wokuchaneka ukuqinisekisa ukuchaneka kolwazi lolawulo loqwalaselo.
Xa ulungiselela ulungiselelo lwenkonzo ye-OTN, lungiselela inkcazo yolwazi lwe-interface nganye, uze uqokelele ulwazi lwe-OTN nge-interface eya emantla ebonelelwa yi-OTN NMS, uze udibanise inkcazo efanelekileyo nolwazi lwezibuko oluqokelelwe sisixhobo se-IP nge-interface eya emantla. Ulawulo olusekelwe kwiqonga lweziteshi ze-OTN kunye neekhonkco ze-IP lususa imfuneko yokuhlaziywa kolwazi ngesandla.
Ukuze usebenzise inethiwekhi yokudlulisa i-DCI, zama ukuphepha ukusebenzisa ulungiselelo lwenkonzo yokudibanisa umbane. Le ndlela inzima kakhulu kwingqiqo yolawulo, kwaye ayisebenzi kwimodeli yenethiwekhi ye-DCI. Ingathintelwa kwasekuqaleni koyilo lwe-DCI.
4 Ulawulo lwe-alamu
Ngenxa yolawulo oluntsonkothileyo lwe-OTN, ukujonga imiqondiso ngexesha lokudluliselwa komgama omde, kunye nokudibanisa kunye nokwakha iinxalenye zeenkonzo ezahlukeneyo, impazamo ingaxela imiyalezo emininzi okanye amakhulu e-alamu. Nangona umenzi ehlukanise ii-alamu zamanqanaba amane, kwaye i-alamu nganye inegama elahlukileyo, iseyinkimbinkimbi kakhulu ngokwembono yokusebenza kunye nokugcinwa kwenjineli, kwaye ifuna abasebenzi abanamava ukufumanisa unobangela wokungaphumeleli kwasekuqaleni. Umsebenzi wokuthumela impazamo kwizixhobo zemveli ze-OTN usebenzisa ikakhulu imodem ye-SMS okanye i-imeyile push, kodwa le misebenzi mibini ikhethekile ekudityanisweni neqonga lolawulo lwe-alamu yenethiwekhi ekhoyo kwinkqubo esisiseko yenkampani ye-Intanethi, kwaye iindleko zophuhliso olwahlukileyo ziphezulu, ngoko ke kufuneka kwenziwe okungakumbi. Ujongano oluqhelekileyo oluya emantla luqokelela ulwazi lwe-alamu, lwandise imisebenzi ngelixa lugcina amaqonga akhoyo enkampani afanelekileyo, kwaye emva koko lutyhala i-alamu kwinjineli yokusebenza kunye nokugcinwa.
Ke ngoko, kubasebenzi bokusebenza nokugcina, kuyimfuneko ukuvumela iqonga lidibanise ngokuzenzekelayo ulwazi lwe-alamu oluveliswe yimpazamo ye-OTN, uze emva koko ufumane ulwazi. Ke ngoko, qala usete udidi lwe-alamu kwi-OTN NMS, uze wenze umsebenzi wokuthumela nokuhlola kwiqonga lokugqibela lolawulo lolwazi lwe-alamu. Indlela ye-alamu ye-OTN ngokubanzi kukuba i-NMS iya kuseta kwaye ityhale zonke iintlobo zokuqala nezesibini zee-alamu kwiqonga lolawulo lolwazi lwe-alamu, uze emva koko iqonga lihlalutye ulwazi lwe-alamu lokuphazamiseka kwenkonzo enye, ulwazi oluphambili lwe-alamu yokuphazamiseka kwendlela ye-optical kunye (ukuba lukhona) ulwazi lwe-alamu yokutshintsha ukhuseleko lutyhalelwa kwinjineli yokusebenza nokugcina. Ulwazi olungentla lunokusetyenziselwa ukuchonga iimpazamo kunye nokucutshungulwa. Xa useta ulwamkelo, ungenza useto lwesaziso sefowuni kwii-alamu ezinkulu ezifana nokusilela kwesignali edibeneyo okwenzeka kuphela xa iifayibha ze-optical zaphukile, ezifana nezi zilandelayo:
Inkcazelo ye-alamu yesiTshayina
Inkcazelo ye-alamu yesiNgesi Uhlobo lwe-alamu Ubunzima kunye nokulinganiselwa
Ukulahleka kweSignali yoMthwalo weLayer ye-OMS I-OMS_LOS_P I-Alarm yoNxibelelwano ebalulekileyo (FM)
Igalelo/Isiphumo Ukulahleka Kwesignali Edibeneyo I-MUT_LOS I-Alarm Yonxibelelwano Engxamisekileyo (FM)
Ukulahlekelwa ngumthwalo we-OTS
I-Alarm yoNxibelelwano yeSignali ye-OTS_LOS_P ebalulekileyo (FM)
Isalathisi sokulahlekelwa ngumthwalo we-OTS I-OTS_PMI I-Alarm yoNxibelelwano engxamisekileyo (FM)
I-interface eya emantla ye-NMS, efana ne-interface ye-XML exhaswa yiHuawei kunye ne-ZTE Alang ngoku, ikwasetyenziswa rhoqo ukutyhala ulwazi lwe-alamu.
5 Ulawulo lokuSebenza
Uzinzo lwenkqubo ye-OTN luxhomekeke kakhulu kwidatha yokusebenza yemiba eyahlukeneyo yenkqubo, njengolawulo lwamandla okukhanya kwefayibha yesiqu, ulawulo lwamandla okukhanya kwetshaneli nganye kwisignali ephindaphindeneyo, kunye nolawulo lwe-margin yenkqubo ye-OSNR. Oku kuqulathwe kufuneka kongezwe kwiprojekthi yokubeka esweni inkqubo yenethiwekhi yenkampani, ukuze kukwaziwe ukusebenza kwenkqubo nangaliphi na ixesha, kwaye kuphuculwe ukusebenza ngexesha ukuqinisekisa uzinzo lwenethiwekhi. Ukongeza, ukusebenza kwefayibha ixesha elide kunye nokubeka esweni umgangatho kungasetyenziselwa ukufumanisa utshintsho kwindlela yefayibha, ukuthintela abanye ababoneleli befayibha ekutshintsheni indlela yefayibha ngaphandle kwesaziso, okubangela iindawo ezingabonakaliyo ekusebenzeni nasekugcinweni, kunye nokuvela komngcipheko wendlela yefayibha. Ewe, oku kufuna inani elikhulu ledatha yoqeqesho lwemodeli, ukuze ukufunyanwa kotshintsho lwendlela kube nokuchaneka ngakumbi.
6. Ulawulo lwe-DCN
I-DCN apha ibhekisa kwinethiwekhi yonxibelelwano yolawulo lwezixhobo ze-OTN, enoxanduva lolwakhiwo lwenethiwekhi yolawulo lwento nganye yenethiwekhi ye-OTN. Inethiwekhi ye-OTN iya kuchaphazela ubungakanani kunye nobunzima benethiwekhi ye-DCN. Ngokubanzi, kukho iindlela ezimbini zenethiwekhi ye-DCN:
1. Qinisekisa ii-NE zesango ezisebenzayo nezilindileyo kuyo yonke inethiwekhi ye-OTN. Ezinye ii-NE ezingezizo ezesango zii-NE eziqhelekileyo. Imiqondiso yolawulo yazo zonke ii-NE eziqhelekileyo ifikelela kwi-NE zesango ezisebenzayo nezilindileyo ngetshaneli ye-OSC kwi-OTS layer kwi-OTN, uze uqhagamshele kwinethiwekhi ye-IP apho i-NMS ikhoyo. Le ndlela inokunciphisa ukuthunyelwa kwezinto zenethiwekhi kwinethiwekhi ye-IP apho i-NMS ikhoyo, kwaye isebenzise i-OTN ngokwayo ukusombulula ingxaki yolawulo lwenethiwekhi. Nangona kunjalo, ukuba i-trunk fiber iyaphazamiseka, izinto zenethiwekhi ezikude ezifanelekileyo nazo ziya kuchaphazeleka kwaye aziyi kulawulwa.
2. Zonke izinto zenethiwekhi zenethiwekhi ye-OTN zicwangciswe njengezinto zenethiwekhi yesango, kwaye into nganye yenethiwekhi yesango inxibelelana nenethiwekhi ye-IP apho i-NMS ibekwe khona ngokuzimeleyo ngaphandle kokudlula kwitshaneli ye-OSC. Oku kuqinisekisa ukuba unxibelelwano lolawulo lwezinto zenethiwekhi aluchaphazeleki kukuphazamiseka kwefayibha ephambili ye-optical, kwaye izinto zenethiwekhi zisenokulawulwa kude, zonke eziqhagamshelwe kwinethiwekhi ye-IP, kwaye iindleko zokusebenza nokugcinwa kwabasebenzi benethiwekhi ye-IP yesiqhelo nazo ziya kuncitshiswa.
Ekuqaleni kokwakhiwa kwenethiwekhi ye-DCN, ucwangciso lwezinto zenethiwekhi kunye nokwabiwa kweedilesi ze-IP kufuneka kwenziwe. Ngokukodwa, iseva yolawulo lwenethiwekhi kufuneka yahlulwe kwezinye iinethiwekhi kangangoko kunokwenzeka xa isetyenziswa. Ngaphandle koko, kuya kubakho amakhonkco amaninzi e-mesh kwinethiwekhi kamva, kwaye i-network jitter iya kuba yinto eqhelekileyo ngexesha lokulungiswa, kwaye izinto zenethiwekhi eziqhelekileyo aziyi kuqhagamshelwa. Iingxaki ezifana ne-gateway network element ziya kuvela, kwaye idilesi yenethiwekhi yemveliso kunye nedilesi yenethiwekhi ye-DCN ziya kusetyenziswa kwakhona, nto leyo eya kuchaphazela inethiwekhi yemveliso.
