3 Ulawulo loLungiselelo
Ngexesha loqwalaselo lwetshaneli, ubumbeko lwenkonzo, uqwalaselo lwe-optical layer logical link configuration, kunye nonxulumano olubonakalayo lwemephu yetopology iyafuneka.Ukuba umjelo omnye unokuqulunqwa ngendlela yokukhusela, ukucwangciswa kweshaneli ngeli xesha kuya kuba nzima ngakumbi, kwaye ulawulo olulandelayo loLungiselelo luya kuba nzima ngakumbi.Itheyibhile yenkonzo ezinikeleyo iyafuneka nje ukulawula isalathiso setshaneli, kwaye izalathiso zoshishino kufuneka zahlulwe kwitheyibhile, kusetyenziswa imigca eqinileyo nedayiweyo.Xa imbalelwano phakathi kwamajelo e-OTN kunye neekhonkco ze-IP zilawulwa, ngokukodwa kwimeko yokukhusela i-OTN, enye ikhonkco ye-IP kufuneka ihambelane namajelo amaninzi e-OTN.Ngeli xesha, isixa solawulo siyenyuka kwaye ulawulo lunzima, nto leyo enyusa ulawulo lweetafile ze-excel.Iimfuno, ukulawula ngokupheleleyo zonke izinto zeshishini, ukuya kuthi ga kwi-15. Xa injineli ifuna ukulawula ikhonkco elithile, kufuneka ifumane ifom egqwesileyo, kwaye emva koko uye kwi-NMS yomenzi ukuze ufumane ehambelanayo, emva koko wenze umsebenzi. ulawulo.Oku kufuna ungqamaniso lolwazi kumacala omabini.Ukusukela ukuba iqonga le-NMS le-OTN kunye nokugqwesa okwenziwe yinjineli ziidatha ezimbini ezenziwe ngumntu, kulula ukuba ulwazi lungabikho kwi-sync.Nayiphi na impazamo iya kubangela ukuba ulwazi lweshishini lungahambelani nobudlelwane bokwenene.Ngokuhambelanayo, inokuchaphazela ishishini xa utshintsha kwaye uhlengahlengisa.Ngoko ke, idatha yezixhobo zomenzi iqokelelwa kwiqonga lolawulo ngokusebenzisa ujongano olusenyakatho, kwaye ke ulwazi lwekhonkco ye-IP luhambelana neli qonga, ukuze ulwazi lulungelelaniswe ngokuzenzekelayo ngokuhambelana notshintsho lwenkonzo yenethiwekhi ekhoyo. , kunye nolawulo oluphakathi kolwazi luqinisekisiwe.kunye nomthombo omnye wokuchaneka ukuqinisekisa ukuchaneka kolwazi lolawulo loqwalaselo.
Xa uqwalasela unikezelo lwenkonzo ye-OTN, lungiselela inkcazo yolwazi lwe-interface nganye, kwaye emva koko uqokelele ulwazi lwe-OTN ngojongano oluya kumntla olunikwe yi-OTN NMS, kwaye udibanise inkcazo efanelekileyo kunye nolwazi lwezibuko oluqokelelwe sisixhobo se-IP ngojongano olusenyakatho.Ulawulo olusekelwe kwiqonga leziteshi ze-OTN kunye neekhonkco ze-IP zisusa imfuno yokuhlaziywa kolwazi lwencwadana.
Ukusetyenziswa kwenethiwekhi yothumelo ye-DCI, zama ukunqanda ukusetyenziswa kolungiselelo lwenkonzo yombane.Le ndlela inzima kakhulu kwingqiqo yolawulo, kwaye ayisebenzi kwimodeli yenethiwekhi ye-DCI.Inokuphetshwa kwasekuqaleni koyilo lwe-DCI.
4 Ulawulo lwealam
Ngenxa yolawulo oluntsonkothileyo lwe-OTN, ukujonga umqondiso ngexesha lothumelo lomgama omde, kunye ne-multiplexing kunye nendlwane yamasuntswana eenkonzo ezahlukeneyo, impazamo inokuxela inqwaba okanye amakhulu emiyalezo ye-alam.Nangona umenzi ehlele ii-alam zibe ngamanqanaba amane, kwaye i-alam nganye inegama elahlukileyo, isenzima kakhulu ngokwembono yokusebenza kwenjineli kunye nokugcinwa kwayo, kwaye ifuna abasebenzi abanamava ukufumanisa unobangela wokusilela kwasekuqaleni.Umsebenzi wokuthumela impazamo yezixhobo zemveli ze-OTN ikakhulu isebenzisa imodem ye-SMS okanye ukutyhala i-imeyile, kodwa imisebenzi emibini ikhethekileyo yokudibanisa neqonga lolawulo lwe-alarm yenethiwekhi ekhoyo yenkqubo esisiseko yenkampani ye-Intanethi, kunye neendleko zophuhliso olwahlukileyo luphezulu, ngoko ke iimfuno ezingaphezulu. kufuneka kwenziwe.Ujongano oluqhelekileyo oluya kumntla luqokelela ulwazi lwe-alamu, lwandisa imisebenzi ngelixa lugcina iiplatifti ezifanelekileyo zenkampani, kwaye emva koko ityhala i-alamu kumsebenzi kunye nenjineli yokulondoloza.
Ngoko ke, kubasebenzi bokusebenza kunye nokugcinwa, kuyimfuneko ukuvumela iqonga liguqule ngokuzenzekelayo ulwazi lwe-alamu oluveliswe yiphutha le-OTN, kwaye emva koko ufumane ulwazi.Ngoko ke, qala ngokuseta ulwahlulo lwe-alamu kwi-OTN NMS, uze wenze umsebenzi wokuthumela nowokuhlola kwiqonga lokugqibela lolawulo lwe-alarm.Indlela ye-alamu ye-OTN ngokubanzi kukuba i-NMS iya kumisa kwaye ityhale zonke iintlobo zokuqala kunye neyesibini ze-alamu kwiqonga lolawulo lolwazi lwe-alamu, kwaye ke iqonga liya kuhlalutya ulwazi lwe-alarm yokuphazamiseka kwenkonzo enye, eyona nto iphambili I-alamu yokuphazamiseka kwendlela yokubona. ulwazi kunye (ukuba lukhona) ulwazi lwe-alam yokhuseleko lutyhalelwa kumsebenzi kunye nenjineli yolondolozo.Ezi nkcukacha zintathu zingentla mhlawumbi zingasetyenziselwa ukuxilongwa kweziphoso kunye nokucubungula.Xa useta ulwamkelo, unokuseta useto lwezaziso zefowuni kwii-alam ezinkulu ezinjengokusilela komqondiso odibeneyo okwenzekayo kuphela xa kwaphulwe iintsinga zamehlo, ezifana nezi zilandelayo:
Inkcazo yesiTshayina yeAlam
Inkcazo yeAlarm IsiNgesi Uhlobo lwe-alam Ubungqongqo kunye nokulinganiselwa
ULahleko lwe-OMS yoNxibelelwano lweLayer yeLahleko yoNxibelelwano lweAlarm (FM)
Igalelo/Isiphumo Esidityanisiweyo Ilahleko yoMqondiso MUT_LOS UNxibelelwano oluNgxamisekileyo lweAlarm (FM)
Ilahleko yokuhlawula kwe-OTS ye
Umqondiso OTS_LOS_P weAlam yoNxibelelwano iBalulekileyo (FM)
I-OTS Payload isalathisi seLahleko ye-OTS_PMI iAlam yoNxibelelwano iNgxamisekileyo (FM)
I-interface esenyakatho ye-NMS, efana ne-XML interface exhaswa ngoku yi-Huawei kunye ne-ZTE Alang, isetyenziswa ngokuqhelekileyo ukutyhala ulwazi lwe-alamu.
5 Ulawulo lokuSebenza
Ukuzinza kwenkqubo ye-OTN kuxhomekeke kakhulu kwidatha yokusebenza kwiinkalo ezahlukeneyo zenkqubo, njengolawulo lwamandla okukhanya kwe-trunk fiber, ulawulo lwamandla okukhanya kwitshaneli nganye kwi-multiplexed signal, kunye nenkqubo ye-OSNR yokulawula umda.Ezi ziqulatho kufuneka zongezwe kwiprojekthi yokubeka iliso yenkqubo yenethiwekhi yenkampani, ukuze ukwazi ukusebenza kwenkqubo nangaliphi na ixesha, kunye nokwandisa ukusebenza kwangethuba ukuze kuqinisekiswe uzinzo lothungelwano.Ukongeza, ukusebenza kwefayibha yexesha elide kunye nokubeka iliso komgangatho kungasetyenziselwa ukufumanisa utshintsho kwindlela yokuhambisa ifayibha, ukuthintela abanye ababoneleli befayibha ekutshintsheni i-fiber routing ngaphandle kwesaziso, okukhokelela kwiindawo ezingaboniyo ekusebenzeni nasekugcinweni, kunye nokuvela komngcipheko we-fiber routing.Ngokuqinisekileyo, oku kufuna inani elikhulu ledatha yoqeqesho lomzekelo, ukwenzela ukuba ukufunyanwa kweenguqu zendlela kunokuchaneka ngakumbi.
6. Ulawulo lwe-DCN
I-DCN apha ibhekiselele kuthungelwano lonxibelelwano lolawulo lwezixhobo ze-OTN, ezijongene nesakhiwo sothungelwano lolawulo lwento nganye yenethiwekhi ye-OTN.Inethiwekhi ye-OTN iya kuchaphazela isikali kunye nobunzima benethiwekhi ye-DCN.Ngokubanzi, zimbini iindlela zenethiwekhi ye-DCN:
1. Qinisekisa isango le-NE elisebenzayo nelilindileyo kuyo yonke inethiwekhi ye-OTN.Ezinye iiNE ezingezizo isango ziiNEs eziqhelekileyo.Iimpawu zolawulo zazo zonke iiNEs eziqhelekileyo zifikelela kwisango elisebenzayo kunye ne-standby gateway NEs ngokusebenzisa umjelo we-OSC kuwo wonke umaleko we-OTS kwi-OTN, uze emva koko uQhagamshele kuthungelwano lwe-IP apho i-NMS ikhoyo.Le ndlela inokunciphisa ukuthunyelwa kwezinto zenethiwekhi kwinethiwekhi ye-IP apho i-NMS ikhona, kwaye isebenzise i-OTN ngokwayo ukusombulula ingxaki yolawulo lwenethiwekhi.Nangona kunjalo, ukuba i-trunk fiber iphazamisekile, izinto ezihambelanayo zenethiwekhi ezikude nazo ziyakuchaphazeleka kwaye ziya kuba ngaphandle kolawulo.
2. Zonke izinto zothungelwano zenethiwekhi ye-OTN ziqwalaselwe njengezinto zothungelwano lwesango, kwaye nganye inkalo yenethiwekhi yesango inxibelelana nenethiwekhi ye-IP apho i-NMS ibekwe ngokuzimeleyo ngaphandle kokudlula kwitshaneli ye-OSC.Oku kuqinisekisa ukuba unxibelelwano lolawulo lwezinto zothungelwano aluchatshazelwa kukuphazamiseka kwe-fiber optical main, kwaye izinto zenethiwekhi zisenokulawulwa kude, zonke zixhunyiwe kwinethiwekhi ye-IP, kunye neendleko zokusebenza kunye nokugcinwa kweendleko zemveli. Abasebenzi benethiwekhi ye-IP nabo baya kuncitshiswa.
Ekuqaleni kokwakhiwa kwenethiwekhi ye-DCN, ukucwangciswa kwezinto zenethiwekhi kunye nokwabiwa kwedilesi ye-IP kufuneka kuqhutywe.Ngokukodwa, umncedisi wolawulo womnatha kufuneka abe yedwa kwamanye amanethiwekhi kangangoko kunokwenzeka xa uhambisa.Ngaphandle koko, kuya kubakho amakhonkco amaninzi amaninzi kwinethiwekhi kamva, kwaye i-jitter yenethiwekhi iya kuba yinto eqhelekileyo ngexesha lokugcinwa, kwaye izinto eziqhelekileyo zenethiwekhi aziyi kudibaniswa.Iingxaki ezifana nenkqubo yenethiwekhi yesango iya kubonakala, kwaye idilesi yenethiwekhi yemveliso kunye nedilesi yenethiwekhi ye-DCN iya kusetyenziswa kwakhona, eya kuchaphazela inethiwekhi yokuvelisa.
