3 Kutarisira Kugadziriswa

Munguva yekugadzirisa chiteshi, kugadzirisa sevhisi, kugadzirisa kwe optical layer logical link, uye kugadzirisa kwe link virtual topology map zvinodiwa. Kana chiteshi chimwe chete chingagadziriswa nenzira yekudzivirira, kugadzirisa kwechiteshi panguva ino kuchave kwakaoma, uye manejimendi yeConfiguration inotevera ichave yakaomawo. Tafura yebasa yakatsaurirwa inodiwa kungo tungamira chiteshi, uye nhungamiro dzebhizinesi dzinofanira kusiyaniswa mutafura, uchishandisa mitsara yakasimba uye ine dash. Kana kutaurirana pakati peOTN channels neIP links kuchitarisirwa, kunyanya kana paine kuchengetedzwa kweOTN, IP link imwe chete inofanirwa kuenderana nematanho akawanda eOTN. Panguva ino, huwandu hwemanejimendi hunowedzera uye manejimendi akaoma, izvo zvinowedzerawo manejimendi yetafura dzeexcel. Zvinodiwa, kuti utonge zvizere zvinhu zvese zvebhizinesi, kusvika ku15. Kana mainjiniya achida kutarisira imwe link, anofanirwa kutsvaga fomu yeexcel, uye obva aenda kuNMS yemugadziri kuti awane inoenderana, uye obva aita operation management. Izvi zvinoda kuenderana kweruzivo kumativi ese. Sezvo NMS platform yeOTN neexcel yakagadzirwa ne mainjiniya zviri data mbiri dzakagadzirwa nevanhu, zviri nyore kuti ruzivo rusawirirane. Chero chikanganiso chipi zvacho chichaita kuti ruzivo rwebhizinesi rusawirirane nehukama chaihwo. Saizvozvo, zvinogona kukanganisa bhizinesi pakuchinja nekugadzirisa. Nokudaro, data remugadziri rinounganidzwa kune chikuva chekutonga kuburikidza neinterface yekuchamhembe, uye ipapo ruzivo rweIP link runofananidzwa pachikuva ichi, kuitira kuti ruzivo rugone kugadziriswa otomatiki zvichienderana neshanduko dzebasa renetwork iripo, uye manejimendi yeruzivo inosimbiswa. uye sosi imwe chete yekururama kuona kuti ruzivo rwekugadzirisa magadzirirwo rwakarurama.

Paunenge uchigadzirisa OTN service provisioning, gadzirira tsananguro yeruzivo rwe interface yega yega, wobva waunganidza ruzivo rweOTN kuburikidza ne kuchamhembe kunopihwa neOTN NMS, wobatanidza tsananguro yakakodzera neruzivo rwe port runounganidzwa neIP device kuburikidza ne northbound interface. Kutarisirwa kwe OTN channels ne IP links zvichibva papuratifomu kunobvisa kudiwa kwekuvandudzwa kweruzivo nemaoko.

Pakushandisa network yekutumira yeDCI, edza kudzivirira kushandisa gadziriro yemagetsi yekubatanidza magetsi. Nzira iyi yakaoma zvikuru mukugadzirisa, uye haishande kune DCI network model. Inogona kudzivirirwa kubva pakutanga kwekugadzirwa kweDCI.

4 Kutarisira alamu

Nekuda kwekushanda kwakaoma kweOTN, kutarisa masaini panguva yekutumira masaini kure, uye kuwedzera uye kugadzira ma "sevhisi" akasiyana, kukanganisa kunogona kushuma mameseji ealarm akawanda kana mazana. Kunyangwe mugadziri akaisa ma "alarm" muzvikamu zvina, uye "alarm" yega yega ine zita rakasiyana, ichiri yakaoma zvikuru kubva pakuona kwekushanda nekugadzirisa kweinjiniya, uye inoda vashandi vane ruzivo kuti vaone chikonzero chekukundikana pakutanga. Basa rekutumira zvikanganiso remidziyo yechinyakare yeOTN rinonyanya kushandisa SMS modem kana email push, asi mabasa maviri aya akakosha pakubatanidzwa ne "network alarm management platform" iripo ye "basic system" yekambani yeInternet, uye mutengo wekugadzira wakasiyana wakakwira, saka zvakawanda zvinoda kuitwa. Iyo standard kuchamhembe interface inounganidza ruzivo rwealarm, inowedzera mabasa uku ichichengetedza mapuratifomu akakodzera ekambani, uye yobva yasundira alarm kuinjiniya wekushanda nekugadzirisa.

Saka, kune vashandi vekushanda nekugadzirisa, zvakakosha kuti puratifomu iunganidze otomatiki ruzivo rwealamu rwunogadzirwa nekutadza kweOTN, uye wobva wagamuchira ruzivo rwacho. Saka, tanga waisa kupatsanurwa kwealamu paOTN NMS, wobva waita basa rekutumira nekuongorora papuratifomu yekupedzisira yekutarisira ruzivo rwealamu. Nzira yakajairika yealamu yeOTN ndeyekuti NMS ichaisa nekusundira marudzi ese ekutanga neechipiri ealamu kupuratifomu yekutarisira ruzivo rwealamu, uye ipapo puratifomu ichaongorora ruzivo rwealamu rwekukanganiswa kwebasa rimwe chete, ruzivo rwealamu yekuvhiringidza nzira yemaziso uye (kana iripo) ruzivo rwekudzivirira rwekuchinja alamu zvinosundirwa kuinjiniya wekushanda nekugadzirisa. Ruzivo rwutatu rwuri pamusoro runogona kushandiswa pakuongorora nekugadziriswa kwezvikanganiso. Paunenge uchigadzira reception, unogona kugadzira marongero ekuzivisa runhare rwemaalamu makuru akadai sekukundikana kwechiratidzo checomposite kunoitika chete kana fibers dzemaziso dzatyoka, senge zvinotevera:

Tsananguro yeAlarm yeChinese

Tsananguro yeAlarm yeChirungu Rudzi rweAlarm Kuoma uye kuganhurirwa
Kurasikirwa kweChiratidzo cheOMS Layer Payload OMS_LOS_P Alarm yekutaurirana inokosha (FM)
Kupinda/Kubuda Kwakabatana Kurasikirwa kweSignali MUT_LOS Alarm Yekutaurirana Emergency (FM)
Kurasikirwa kweOTS Payload

Alarm yekutaurirana yeOTS_LOS_P inokosha (FM)
Chiratidzo Chekurasikirwa Kwemutoro weOTS OTS_PMI Alarm Yekutaurirana Inokurumidza (FM)
Nzvimbo yeNMS inoenda kuchamhembe, yakaita seXML interface inotsigirwa neHuawei neZTE Alang parizvino, inowanzoshandiswawo kuburitsa ruzivo rwealamu.

5 Kutarisira Mashandiro

Kugadzikana kweOTN system kunoenderana zvikuru nedata rekushanda kwezvinhu zvakasiyana-siyana zvesystem, zvakaita sekutarisira simba re optical re trunk fiber, kutarisira simba re optical renzira yega yega mu multiplexed signal, uye kutarisira margin system OSNR. Zviri mukati izvi zvinofanirwa kuwedzerwa kupurojekiti yekutarisa network system yekambani, kuitira kuti uzive mashandiro esystem chero nguva, uye kugadzirisa mashandiro nenguva kuti uve nechokwadi chekuti network inogara yakagadzikana. Pamusoro pezvo, kushanda kwenguva refu kwefiber uye kutarisa mhando zvinogona kushandiswawo kuwana shanduko mu fiber routing, kudzivirira vamwe vatengesi ve fiber kuti vasachinje fiber routing pasina chiziviso, zvichikonzera nzvimbo dzisingaonekwe mukushanda nekugadzirisa, uye kuitika kwenjodzi ye fiber routing. Ehe, izvi zvinoda data rakawanda rekudzidzisa modhi, kuitira kuti kuwanikwa kwekuchinja kwe routing kuve kwakarurama.

6. Kutarisira DCN

Pano DCN inoreva network yekutaurirana kwemanejimendi yemidziyo yeOTN, iyo inotarisira chimiro chenetwork chekutarisira chimwe nechimwe chinhu chenetwork cheOTN. Network yeOTN inokanganisawo kukura nekuoma kwenetwork yeDCN. Kazhinji, kune nzira mbiri dzenetwork yeDCN:

1. Simbisa maNE egedhi anoshanda uye akamira ari munetwork yese yeOTN. Mamwe maNE asiri egedhi iNE dzakajairika. Zviratidzo zvemanejimendi eNE dzese dzakajairika zvinosvika kuNE dzegedhi dzinoshanda uye dzakamira kuburikidza neOSC channel kuburikidza neOTS layer muOTN, wobva wabatanidza kune network yeIP uko NMS iri. Nzira iyi inogona kuderedza kuiswa kwezvinhu zvenetwork panetwork yeIP uko NMS iri, uye kushandisa OTN pachayo kugadzirisa dambudziko remanejimendi enetwork. Zvisinei, kana trunk fiber ikakanganiswa, zvinhu zvenetwork zviri kure zvinoenderana nazvo zvichakanganiswawo uye hazvizove mumanejimendi.

2. Zvinhu zvese zvenetwork zveOTN network zvakagadzirirwa sezvinhu zvenetwork yegateway, uye chinhu chimwe nechimwe chenetwork yegateway chinotaura neIP network uko NMS iri yega pasina kupfuura nemugero weOSC. Izvi zvinoita kuti kutaurirana kwemanejimendi kwezvinhu zvenetwork kusakanganiswa nekukanganiswa kwefiber huru ye optical, uye zvinhu zvenetwork zvichiri kugona kutarisirwa kure, zvese zvakabatana neIP network, uye mari yekushanda nekugadzirisa yevashandi veIP network yechinyakare ichaderedzwawo.

Pakutanga kwekuvakwa kwenetwork yeDCN, kuronga zvinhu zvenetwork uye kugoverwa kwekero dzeIP kunofanirwa kuitwa. Kunyanya, network management server inofanira kuparadzaniswa nemamwe manetwork zvakanyanya sezvinobvira pakuisa. Zvikasadaro, pachava nema mesh links akawanda munetwork gare gare, uye network jitter ichave yakajairika panguva yekugadzirisa, uye zvinhu zvenetwork zvakajairika hazvizobatanidzwa. Matambudziko akadai segateway network element achaonekwa, uye kero yenetwork yekugadzira nekero yenetwork yeDCN zvichashandiswazve, izvo zvichakanganisa network yekugadzira.
