Mushure mekunge network yeDCI yatanga tekinoroji yeOTN, zvakafanana nekuwedzera basa rese raive risati rambovapo maererano nekushanda. Network yechinyakare yedata center network inetwork yeIP, iyo iri ye logical network technology. OTN muDCI itekinoroji ye physical layer, uye maitiro ekushanda neIP layer nenzira ine hushamwari uye iri nyore inzira refu yekushanda.
Parizvino, chinangwa chekushanda kweOTN chakafanana nechero subsystem yedata center. Zvese izvi zvine chinangwa chekuwedzera kushanda zvakanaka kwezviwanikwa zvakaiswa muzvivakwa zvinodhura zvakanyanya uye kupa rutsigiro rwakanakisisa rwemabasa ekumusoro. Kuvandudza kugadzikana kwehurongwa hwekutanga, kuita kuti mashandiro nemabasa ekugadzirisa ashande zvakanaka, kubatsira mukugoverwa kwezviwanikwa zvine musoro, kuita kuti zviwanikwa zvakaiswa mari zviite basa rakakura, uye kugovera zviwanikwa zvisina kuiswa mari zvine mwero.
Kushanda kweOTN kunosanganisira zvikamu zvakati wandei: manejimendi yedata rekushanda, manejimendi yemidziyo, manejimendi yekugadzirisa, manejimendi yealarm, manejimendi yekushanda, uye manejimendi yeDCN.
1 Ruzivo rweKushanda
Gadzira nhamba padata rezvikanganiso, siyanisa zvikanganiso zvevanhu, zvikanganiso zvehardware, zvikanganiso zvesoftware, uye zvikanganiso zvevamwe, uye ongorora nhamba pamhando dzezvikanganiso zvakanyanya, gadzira zvirongwa zvekugadzirisa zvakanangana, uye gadzira nzira yekugadzirisa otomatiki zvikanganiso mushure mekugadziriswa mune ramangwana. Zvichienderana nekuongorora data rezvikanganiso, sisitimu iyi yakagadzirirwa basa remangwana senge dhizaini yezvivakwa uye kusarudzwa kwemidziyo, kuitira kuderedza mari yekushanda nekuchengetedza gare gare. Kune OTN, ita nhamba dzezvikanganiso kubva kuma optical amplifiers, mabhodhi, ma modules, ma multiplexers, ma cross-device jumpers, trunk fibers, DCN networks, nezvimwewo, tora chikamu muhukuru hwemugadziri, hukuru hwevamwe, nezvimwewo, uye ita ongororo yedata ine mativi akawanda kuti uwane data rakarurama. Inogona kuratidza nemazvo mamiriro aripo enetwork.
Ita nhamba padata rekuchinja, siyanisa kuomarara uye kukanganisa kwekuchinja, govera vashandi, uye shandura zvinoenderana nemaitiro ekuongorora zvinodiwa, hurongwa hwekuchinja, hwindo rekuisa, kuzivisa vashandisi, kuita kwekushanda, uye ongororo pfupi, uye pakupedzisira inogona kuita shanduko dzakasiyana. Yakakamurwa kuita mahwindo, kunyange kurongerwa kuitwa masikati, kuitira kuti kugoverwa kwevashandi vanochinja kuve kwakaringana, kuderedza kumanikidzwa kwebasa nehupenyu, uye kuvandudza mufaro wemainjiniya anoshanda. Inogona zvakare kubatanidza data rekupedzisira rehuwandu uye kurishandisa sereferensi yekushanda zvakanaka kwevashandi uye kugona kwebasa. Panguva imwe chete, inobvumirawo shanduko dzakajairika kuti dzikure munzira yekuenzanisa uye otomatiki, zvichideredza mari dzakasiyana-siyana.
Unganidza nhamba dzekugoverwa kwebasa reOTN kuti dzikubatsire kuziva mashandisirwo enetwork uye kudzora kugoverwa kwenetwork yese uye kugoverwa kwebasa mushure mekunge huwandu hwebhizinesi hwawedzera. Kana ukaita kuti zvinhu zviome, unogona kuziva kuti ndeipi network service iri kushandiswa nechiteshi chimwe chete, senge network yekunze, intranet, HPC network, cloud service network, nezvimwewo. Kana ukanyatsoita kuti zvive nyore, unogona kusanganisa system yese yekufambisa kuti uongorore mashandisirwo etraffic yebhizinesi. Mari dzakasiyana dzebandwidth dzinogoverwa kumadhipatimendi akasiyana ebhizinesi kuti dzivabatsire kugadzirisa traffic yebhizinesi, kudzokorodza nekugadzirisa nzira dzekushanda dzisingashandiswi zvakanyanya chero nguva, uye kuwedzera nzira dzebhizinesi dzinoshandiswa zvakanyanya.
Data rekugadzikana kwenhamba, iro riri data guru rekutarisa reSLA, ndirowo bakatwa reDamocles riri pamusoro pevashandi vese vekushanda nekuchengetedza. Nhamba dzedata rekugadzikana dzeOTN dzinofanira kusiyaniswa nekuda kwekudzivirira kwadzo. Semuenzaniso, kana nzira imwe chete ikakanganiswa, bandwidth yese paIP layer haizokanganisike, kana ichabatanidzwa muSLA; kana bandwidth yeIP ikaderedzwa nehafu, asi bhizinesi harizokanganisike, kana ichabatanidzwa muSLA; Kana kutadza kwechiteshi chimwe chete kuchibatanidzwa muSLA; kuwedzera kwekunonoka kwenzira yekudzivirira hakukanganisi bandwidth yenetwork, asi kune kukanganisa pabhizinesi, kana ichibatanidzwa muSLA, nezvimwewo. Muitiro wakajairika ndewekuzivisa divi rebhizinesi nezvenjodzi dzakadai sekuchinja kwejitter nekunonoka usati wavaka. SLA yekupedzisira inoverengerwa zvichibva pahuwandu hwenzira dzisina kunaka * bandwidth yechiteshi chimwe chisina kunaka, yakakamurwa nenhamba yese yenzira * huwandu hwebandwidth yechiteshi chinoenderana, uye yozowedzerwa ne Zvichibva panguva yeimpact, kukosha kwakawanikwa kunoshandiswa sechiyero chekuverenga cheSLA.
2 Kutarisira Zvinhu
Zvinhu zvemidziyo yeOTN zvinodawo manejimendi yehupenyu hwese (kusvika, online, scrapping, processing fault), asi kusiyana nemasevha, network switches nezvimwe zvishandiso, chimiro chemidziyo yeOTN chakaoma zvikuru. Midziyo yeOTN inosanganisira mabhodhi akawanda anoshanda, saka zvakakosha kugadzira modhi yekutarisira zvizere zvinhu panguva yekutarisira. Puratifomu huru yeIP asset management mudata center yakavakirwa pamasevha nemaswitch, uye level yemudziyo wemaster-slave ichaiswa. Pahwaro uhwu hweOTN, level yemaster-slave ichasanganisira manejimendi yehierarchical, asi kune akawanda ma layers. Level yemanejimendi inonyanya kuitwa ne network element->subrack->board card->module:
2.1. Chinhu chenetwork mudziyo chaiwo, usina zvinhu zvepanyama. Chinoshandiswa pakutarisira uye poindi yekutanga ine musoro munetwork yeOTN, uye ndechechikamu chekutanga mukutarisira network yeOTN. Kamuri remidziyo chaiyo rinogona kuva neNE imwe chete kana maNE akawanda. Chinhu chenetwork chine masubrack akawanda, akadai seoptical layer subracks, electrical layer subracks, uye external multiplexers uye demultiplexers zvinoonekwawo sesubrack. Subrack yega yega inogona kubatanidzwa mumutsara uye ndeye subrack mukati mewebsite yechinhu chimwe chete chenetwork. Kuverenga nhamba. Pamusoro pezvo, chinhu chenetwork hachina nhamba yeSN yeasset, saka inofanira kuenderana neplatform yekutungamira panyaya iyi, kunyanya neruzivo ruri pane runyorwa rwekutenga uye platform yekutarisira mashandiro nekuchengetedza, kuitira kudzivirira kuferefetwa kweasset kusingaenderane. Pamusoro pezvose, chinhu chenetwork iasset chaiyo. .
2.2. Chikamu chikuru chezvishandiso zveOTN i chassis, kureva subrack, iyo iri padanho rechipiri rechinhu che network chedanho rekutanga. Ichi chikamu chechipiri, uye chinhu che network chine kanenge mudziyo mumwe chete we subrack. Aya ma subrack akakamurwa kuita mamodheru akasiyana evagadziri vakasiyana, ane mabasa akasiyana, anosanganisira ma electronic subrack, ma photon subrack, ma general subrack, nezvimwewo. Subrack ine nhamba chaiyo yeSN, asi nhamba yayo yeSN haigone kuwanikwa otomatiki kuburikidza ne network management platform, uye inogona kungotariswa panzvimbo yacho chete. Hazviwanzoitiki kufambisa nekuchinja subrack mushure mekunge yapinda online. Mabhodhi akasiyana-siyana anoiswa mu subrack.
2.3. Mukati mechikamu chechipiri cheOTN, mune nzvimbo dzebasa dzakatarwa dzekuisa. Nzvimbo idzi dzine nhamba uye dzinoshandiswa kuisa mabhodhi akasiyana-siyana ebasa enetwork dze optical. Mabhodhi aya ndiwo hwaro hwekutsigira masevhisi eOTN network, uye bhodhi rega rega rinogona kubvunza SN yaro kuburikidza ne network management system. Mabhodhi aya ndiwo mayuniti echitatu-level mu OTN asset management. Mabhodhi akasiyana-siyana ebhizinesi ane saizi dzakasiyana, anogara munzvimbo dzakasiyana, uye ane mabasa akasiyana. Naizvozvo, kana bhodhi richida kupihwa kune chikamu chechipiri-level unit subrack, asset platform inofanira kubvumira bhodhi rimwe chete kushandisa nzvimbo dzakawanda kana hafu kuti dzienderane nenhamba dzenzvimbo dziri pachikamu ichi.
2.4. Kutarisirwa kwezvinhu zveOptical module. Mamodule anoenderana nekushandiswa kwemabhodhi ebasa. Mabhodhi ese ebhizinesi anofanira kubvumidza kuva neoptical module, asi haasi mabhodhi ese eOTN equipment anofanira kuiswa mumamodule eoptical, saka mabhodhi anofanirawo kubvumidzwa. Hapana module iripo. Module yega yega yeoptical ine nhamba yeSN, uye module yakaiswa pabhodhi inofanira kuenderana nenhamba yechiteshi chebhodhi kuti zvive nyore kutsvaga nzvimbo.
Ruzivo rwese urwu runogona kuunganidzwa kuburikidza neinterface yekuchamhembe kwepuratifomu yekutarisira network, uye kururama kweruzivo rwezvinhu kunogona kutarisirwa kuburikidza nekuunganidza online uye kusimbiswa uye kuenzaniswa kweinternet. Pamusoro pezvo, michina yeOTN inosanganisirawo ma optical attenuators, ma short jumpers, nezvimwewo. Midziyo iyi inogona kutarisirwa zvakananga semidziyo inoshandiswa.
