3 Kuronga Kwekugadzirisa
Panguva yekumisikidzwa kwechiteshi, kugadziridzwa kwesevhisi, optical layer inonzwisisika link kumisikidza, uye yekubatanidza virtual topology mepu kumisikidzwa inodiwa.Kana chiteshi chimwe chete chinogona kugadzirwa nenzira yekudzivirira, gadziriso yechiteshi panguva ino ichanyanya kuomarara, uye iyo inotevera Magadzirirwo manejimendi zvakare ichave yakaoma.Tafura yakatsaurirwa sevhisi inodiwa kungo gadzirisa gwara rechiteshi, uye mafambiro ebhizinesi anofanirwa kusiyaniswa mutafura, uchishandisa mitsara yakasimba uye yakadhindwa.Kana iyo tsamba yekunyorerana pakati peOTN chiteshi uye IP link ichigadziriswa, kunyanya panyaya yekuchengetedzwa kweOTN, imwe IP link inoda kuenderana nematanho akawanda eOTN.Panguva ino, huwandu hwekutarisira hunowedzera uye manejimendi akaomesesa, izvo zvinowedzerawo manejimendi epamusoro matafura.Zvinodiwa, kubata zvachose zvinhu zvese zvebhizinesi, kusvika ku15. Kana injiniya achida kubata imwe link, anofanirwa kutsvaga iyo excel fomu, obva aenda kuNMS yemugadziri kuti awane zvinoenderana, obva aita oparesheni. management.Izvi zvinoda kuwiriraniswa kwemashoko kumativi ose.Sezvo NMS papuratifomu yeOTN uye yakanakisa yakagadzirwa nainjiniya ari maviri akagadzirwa nevanhu data, zviri nyore kuti ruzivo rwuve kunze kwekuenderana.Chero kukanganisa kuchaita kuti ruzivo rwebhizimisi rive rinopesana nehukama chaihwo.Saizvozvo, zvinogona kukanganisa bhizinesi pakuchinja uye kugadzirisa.Naizvozvo, iyo data yezvigadzirwa zvemugadziri inounganidzwa kune manejimendi chikuva kuburikidza nechamhembe, uye ipapo ruzivo rweiyo IP link inofananidzwa papuratifomu iyi, kuitira kuti ruzivo rugone kugadziridzwa otomatiki maererano nekushandurwa kwesevhisi yetiweki iripo. , uye hutungamiri hwepakati hwemashoko hunovimbiswa.uye chitubu chimwechete chechokwadi chekuvimbisa kurongeka kweruzivo rwekugadzirisa manejimendi.
Paunenge uchigadzirisa kupihwa kwesevhisi yeOTN, gadzirira tsananguro yeruzivo rwechiratidziro chega chega, wobva waunganidza ruzivo rweOTN kuburikidza nechamhembe chinopihwa neOTN NMS, uye batanidza tsananguro yakakodzera neruzivo rwechiteshi chakaunganidzwa neIP mudziyo kuburikidza nechamhembe.Iyo papuratifomu-yakavakirwa manejimendi yeOTN chiteshi uye IP link inobvisa kudiwa kwebhuku reruzivo rwekuvandudza.
Nekushandisa iyo DCI transmission network, edza kudzivirira kushandiswa kwemagetsi muchinjiko-kubatanidza masevhisi ekugadzirisa.Iyi nzira yakaoma zvakanyanya mukutungamira mantiki, uye haishande kune DCI network modhi.Inogona kudzivirirwa kubva pakutanga kweDCI dhizaini.
4 Alarm management
Nekuda kwekuomerwa kwekutonga kweOTN, kutarisa kwemasaini panguva yekufambisa daro refu, uye kuwanda uye nesting yezvikamu zvakasiyana-siyana zvesevhisi, kukanganisa kunogona kushuma makumi kana mazana emashoko aramu.Kunyangwe mugadziri akaisa maaramu mumatanho mana, uye alarm yega yega ine zita rakasiyana, ichiri kuomarara zvakanyanya kubva pakuona kwekushanda kweinjiniya uye kugadzirisa, uye zvinoda vashandi vane ruzivo kuti vaone chakakonzera kutadza kwekutanga.Iko kutadza kutumira basa kwechinyakare OTN michina inonyanya kushandisa SMS modem kana email push, asi iwo maviri mabasa akakosha kusanganisa neiyo iripo network alarm management platform yeInternet kambani yekutanga system, uye mutengo wekusimudzira wakasiyana wakakwira, saka zvimwe zvinodiwa. kuti zviitwe.Iyo yakajairwa northbound interface inounganidza ruzivo rwealarm, inowedzera mabasa ichichengeta iyo kambani iripo yakakodzera mapuratifomu, uye yobva yasundira alarm kune anoshanda uye kugadzirisa mainjiniya.
Naizvozvo, kune vashandi vekushanda nekugadzirisa, zvinodikanwa kuti chikuva chishandure otomatiki ruzivo rwealarm inogadzirwa neOTN kukanganisa, uye wozogamuchira ruzivo.Naizvozvo, tanga waisa iyo alarm class paOTN NMS, wobva waita basa rekutumira nekuongorora pane yekupedzisira alarm information management platform.Iyo general OTN alarm nzira ndeyokuti iyo NMS ichaisa uye kusundira ese ekutanga uye yechipiri marudzi earamu kune aramu ruzivo rwekutarisira chikuva, uye ipapo chikuva chinozoongorora ruzivo rwearamu yekukanganisa kwesevhisi imwe chete, iyo huru Iyo yekuona nzira yekukanganisa alarm. ruzivo uye (kana iripo) yekudzivirira switching alarm ruzivo inosundirwa kune oparesheni uye kugadzirisa mainjiniya.Ruzivo rwutatu rwuri pamusoro runogona kushandiswa pakuongorora kukanganisa uye kugadzirisa.Paunenge uchiseta reception, unogona kuseta zviziviso zvefoni maalarm makuru senge composite chiratidzo kutadza kunoitika chete kana optical fibers yatyorwa, senge anotevera:
Alarm Chinese tsananguro
Alarm Shona tsananguro Alarm type Severity and limitation
OMS Layer Payload Signal Kurasika OMS_LOS_P Nhaurirano Alarm Critical (FM)
Kupinza/Kubuditsa Yakasanganiswa Chiratidzo Kurasika MUT_LOS Nhaurirano Alarm Emergency (FM)
OTS Payload Kurasikirwa kwe
Signal OTS_LOS_P Nhaurirano Alarm Critical (FM)
OTS Payload Loss Indication OTS_PMI Yekutaurirana Alarm Urgent (FM)
Iyo yekuchamhembe yeNMS interface, senge XML interface parizvino inotsigirwa neHuawei neZTE Alang, inowanzoshandiswa kusunda ruzivo rwealarm.
5 Performance Management
Kugadzikana kweOTN system kunoenderana zvakanyanya nekuita data kweakasiyana maficha sisitimu, senge optical simba manejimendi yetrunk fiber, iyo optical simba manejimendi ega ega chiteshi muchiratidzo chemultiplex, uye system OSNR margin management.Izvi zviri mukati zvinofanirwa kuwedzerwa kune yekutarisa purojekiti yekambani network network, kuitira kuti uzive maitirwo ehurongwa chero nguva, uye nekugadzirisa mashandiro acho nenguva kuti ive nechokwadi chekugadzikana kwetiweki.Mukuwedzera, kushanda kwenguva refu kwefiber uye kutarisa kwehutano kunogona kushandiswawo kutsvaga kuchinja kwefiber routing, kudzivirira vamwe vatengesi ve fiber kubva pakuchinja fiber routing pasina chiziviso, zvichiita kuti mapofu ashande nekugadzirisa, uye kuitika kwefiber routing ngozi.Zvechokwadi, izvi zvinoda huwandu hwemashoko ekudzidzira kwemuenzaniso, kuitira kuti kuwanikwa kwekuchinja kwenzira kunogona kuva kwakarurama.
6. DCN kutarisira
Iyo DCN pano inoreva manejimendi ekukurukurirana network yemidziyo yeOTN, iyo inoona nezve network yemaitiro ekutonga kweimwe netiweki element yeOTN.Iyo OTN network ichakanganisawo chiyero uye kuoma kweiyo DCN network.Kazhinji, kune nzira mbiri dzeDCN network:
1. Simbisa iyo inoshanda uye yakamirira gedhi NEs mune yese OTN network.Mamwe asiri-gedhi NE maNE akajairwa.Iwo manejimendi eese akajairwa maNE anosvika kune anoshanda uye akamirira gedhi NEs kuburikidza neOSC chiteshi mhiri kweOTS layer muOTN, uyezve Batanidza kune IP network panowanikwa NMS.Iyi nzira inogona kuderedza kutumirwa kwezvinhu zvetiweki pane IP network panowanikwa NMS, uye shandisa iyo OTN pachayo kugadzirisa dambudziko rekutarisira network.Nekudaro, kana trunk fiber ikakanganiswa, iyo inoenderana kure netiweki zvinhu zvinokanganisika uye ichave kunze kwekutonga.
2. Zvinhu zvese zvenetiweki zveOTN network zvakagadziridzwa senge gedhi network zvinhu, uye yega yega yetiweki network inotaurirana neIP network uko NMS inowanikwa yakazvimiririra isina kuenda kuburikidza neOSC chiteshi.Izvi zvinovimbisa kuti manejimendi kutaurirana kwezvinhu zvetiweki hazvikanganiswe nekukanganiswa kweiyo main optical fiber, uye zvinhu zvenetiweki zvichiri kudzorwa kure, izvo zvese zvakabatana neiyo IP network, uye mari yekushanda nekugadzirisa zvechinyakare. IP network vashandi vachaderedzwawo.
Pakutanga kwe DCN network kuvaka, network element kuronga uye IP kero kugoverwa kunofanirwa kuitwa.Kunyanya, iyo network manejimendi server inofanirwa kuve yakaparadzaniswa kubva kune mamwe ma network zvakanyanya sezvinobvira paunenge uchiendesa.Zvikasadaro, pachave neakawandisa mesh link munetiweki gare gare, uye network jitter ichave yakajairika panguva yekugadzirisa, uye zvakajairwa network zvinhu hazvibatanidzwe.Zvinetso zvakaita senge gedhi network element ichaonekwa, uye kero yekugadzira network uye kero yeDCN network ichashandiswa zvakare, izvo zvinokanganisa network yekugadzira.
