Kana varidzi venzvimbo dzedata vachivaka network yekubatanidza nzvimbo dzedata, vanonyanya kufunga nezvenyaya dzakadai sebandwidth yakakura, kunonoka kwakaderera, huwandu hwakawanda, kutumirwa nekukurumidza, kushanda nyore uye kugadzirisa, uye kuvimbika kwakanyanya. Parizvino, tekinoroji huru yeOTN inonyanya kudzorwa nevagadziri vemidziyo mikuru yemafoni (machipisi anokurukurwa zvakasiyana), akadai seHuawei, ZTE, naAran. Vatengi vakuru vavanosangana navo ndevashandi vefoni yechinyakare, saka zvinhu zveOTN zvakagadzirwa kuti zvienderane nemabasa evashandi ava. Nekuda kweizvi, OTN iri kushandiswa zvakanyanya mumashandisirwo enetwork eDCI muindasitiri yeInternet. Matambudziko mazhinji akasiyana.
Hunhu hwemidziyo yeOTN matambudziko akafanana anosangana neDCI, mari yakawanda yebhizinesi, kugona kwakasimba kweOAM kwenetwork, kugona kuronga nekuwanda kwema bandwidth akasiyana-siyana, kushivirira kukanganisa kwemutsara mumamiriro ekureba, uye kushandiswa kwemagetsi akaderera. Zvinhu zvakaita sekushandiswa kwesimba kushoma kwemidziyo.
1. Kugona kushandisa mari yakawanda mubhizinesi kunoda kuti vashandi veO&M vave nehunyanzvi, vavimbe zvakanyanya nerutsigiro rwehunyanzvi kubva kuvagadziri, uye vave netekinoroji yakavharwa.
2. Hunhu hweOAM hwakasimba, mitemo isingachinji, kubatana kwakaoma uye kwakazvimirira nema cross-network, uye mabasa asina basa zvinounzawo mari yakawanda yekutumira nekushanda kune network yeDCI.
3. Kugona kwakasiyana kwekuronga granule kunoita kuti chimiro chefuremu yekubatanidza masevhisi chive chakaoma uye mabyte ane maburi akawanda.
4. Kushivirira kukanganisa kwemutsetse murefu kunoita kuti algorithm yeFEC ive yakaoma, inotora mari yakawanda uye inotora nguva yakareba kugadzirisa
5. Modhi yemagetsi ye48V-DC yemidziyo yeOTN yakasiyana nemakabati e19-inch 220V-AD (kana 240V-DC) anoshandiswa munzvimbo zhinji dzedata. Kuiswa kwacho kwakaoma uye kunoda kushandurwa kwesimba mukamuri remakombiyuta.
6. Midziyo yeOTN yechinyakare ine furemu hombe, isingakodzeri kuiswa mumakabati akajairwa, uye huwandu hwesimba rayo hahuna kukwira. Kuwedzera kwakazotevera kunonetsa uye kunoda kuti makabati atamiswe kana kuvakwa patsva.
Parizvino, network yedu yeDCI inonyanya kupa mapaipi edata repakati pedata. Hunhu hukuru hwebhizinesi ndeihu: zvinodiwa zvebandwidth imwe chete uye imwe chete, bandwidth hombe, masevhisi epakati pedata (kunyanya multi-active IDC, masevhisi makuru edata)) ine zvinodiwa zvishoma zvekunonoka uye zvinodiwa zvakanyanya zvekugadzikana kwenetwork; panguva imwe chete, nekuda kwekushaikwa kwevashandi vane hunyanzvi uye tekinoroji muindasitiri yeInternet, mashandiro nekuchengetedzwa kwemanetwork eDCI kunofanirwa kuve "kuri nyore" "kuri nyore" uye "kuri nyore" - zvinhu zvakakosha zvinotaurwa katatu (kupi? Haisi rudzi rwenetwork here?); kukura kwakanyanya kweInternet kunoita kuti zvinodiwa zvekuvaka nekuwedzera zvipfupike (denderedzwa rekuwedzera kweOTN revashandi rinowanzova hafu yegore kusvika pagore rimwe, nepo zvinodiwa zvekuwedzera kweDCI yeInternet zviri mwedzi 1 kusvika 3), Saka, zvakakosha kudzvanya nguva mune zvese.
Saka, OTN inopa mhinduro inoshanda yeDCI, asi OTN haisiyo mhinduro yakakodzera DCI. Zvino sezvo network yeDCI iri kukura, pane kudiwa kuri kuwedzera kwemhinduro dzakakodzera dzekugadzirisa matambudziko kubva pamutengo kusvika pakuvaka, kushanda nekugadzirisa. Matambudziko akasiyana-siyana anosangana nawo. Uye matambudziko aya haasi chinhu kunze kwezvinodiwa zvitanhatu zvenetwork yeDCI (bandwidth yakakura, latency yakaderera, density yakakura, kukurumidza kutumirwa, nyore kushanda nekugadzirisa, uye kuvimbika kwakanyanya):
1. bandwidth yakakura, network yekutumira yeDCI haina mhando dzakapfuma dzegranules senge maoperators, bandwidth granules yenetwork yekutumira yeDCI iri nyore, parizvino inowanzoshandiswa 10G kana 100G, mune ramangwana 200G/400G, nezvimwewo, saka hapana chikonzero chekuzviita nebandwidth yakakura Bandwidth pane dzimwe granularity. Nekuda kwekuti daro renji yenetwork yekutumira yeDCI kazhinji harisi refu zvakanyanya, uchishandisa 400G system yakavakirwa pa200G PM-16QAM dual-carrier modulation, daro rekutumira pasina electrical relay rinogona kunge riri makiromita angangoita mazana mashanu (PM-64QAM ingangoita makiromita mazana maviri), kuitira kuti transmission yemetro backbone yeDCI isaganhurwe nedaro.
2. Kunonoka kwakaderera, zvinodiwa nebhizinesi reDCI, kunyanya kana cloud computing ichishandiswa kuunganidza zviwanikwa nenzvimbo dzedata dzakawanda dzinoshanda, kunonoka kunoverengerwa padanho re microsecond, saka nguva yekutumira data inofanira kunge iri pfupi sezvinobvira, ichida kupfuura kumhanya kwechiedza. Bvisa basa rekugadzirisa data risingakoshi uye kuderedza nzira dzekutumira masaini. Semuenzaniso, nekubvisa basa reSD-FEC rinoshandiswa ne100G OTN, imwe chete yekudzokera shure inogona kuchengetedza ma microsecond mazana maviri, uye kubvisa cross-level OTN encapsulation kunogona kuchengetedza makumi ema microsecond, uye kushandisa hubspoke topology kumasevhisi akakosha kuona kuti nzira pfupi ndiyo iri pfupi. Ehe, inogona zvakare kushanda pamwe chete neMPLS neQOS padanho reIP kuyedza kuona kuti kunonoka padanho rekutumira data kuri naniwo.
3. Kuwanda kwemagetsi, U imwe chete, kana 2U, inogona kuwana bandwidth inosvika T, DWDM optical layer uye electrical signal layer connection, kuvandudza density interface yemudziyo, uye kuderedza saizi ye optical module. Semuenzaniso, kushandiswa kweQSFP28 optical modules kunogona kuve nechokwadi chekuti kugona kwe100G access yemudziyo mumwe chete kwavandudzwa zvikuru, uye kushandiswa kweCFP2 daylighting modules padivi pemutsetse kunogona kuve nechokwadi chekuti transmission bandwidth yemudziyo wese yavandudzwa, 1U inogona kuva 1.6T, 3.2T. Parizvino, zvigadzirwa zvakawanda zvine chekuita nazvo zvaonekwa pasi rose, zvakaita seADVA, coriant, ciena nedzimwe makambani. Ehe, Huawei yemuno yatangawo zvigadzirwa zvine chekuita ne902. Zvisinei, kusvika pakupera kwechinyorwa chino, zvinoita sekunge bvunzo ye network access yeMinistry of Industry and Information Technology haisati yapera. Kuwanda kwemagetsi kuchakonzera kushandiswa kwesimba rakawanda uye kupisa kwakawanda. Saka, nzira yekutanga yekubvisa kupisa kweOTN yemhepo yekuruboshwe nerudyi inopinda nekubuda, uye mhepo yepamusoro nepasi inopinda nekubuda inofanira kuraswa.
Zvinodiwa pakutonhodza mudziyo.
4. Kukurumidza kutumirwa, uchishandisa rack yeIDC 19-inch yakajairika iripo, yakafanana nechimiro chemasevha makuru, uchishandisa AC-220V yekupa magetsi zvakananga, kubvisa kudiwa kwekushandurwa kwemagetsi nemakabati, uye kuziva kuti zvinhu zvinogona kuiswa pamasherufu pakarepo mushure mekunge zvasvika mukamuri remakomputa, uye zvinogona kugadziriswa mushure mekubatanidza magetsi. bhizinesi, uye kuita basa rakanaka mubasa rekugamuchira rakajairika kuti riwane kutumirwa nekukurumidza.
5. Kushanda nekugadziriswa kuri nyore, zvinodiwa neDCI business model, daro riri pakati penzvimbo dzedata harizove kure zvakanyanya, uye manejimendi akaomarara, OAM nemamwe mabasa hazvidikanwi kuti zviite basa guru munyaya iyi, uye kugadzirisa kwakaomarara kunoderedzwawo. Zvinovandudza kushanda kwekutumira data, zvinovandudza nguva yekugadzirisa data, uye zvine zvinodiwa zvakanyanya zvetekinoroji uye zvinovharwa zvakanyanya. Kubatanidza masaini zvakananga kuburikidza neEthernet kunobvisa kuomarara kweOTN, saka mainjiniya eIP network echinyakare anogona kushanda nekuchengetedza DCI system. Mushure mekubatanidza ma interfaces matsva ekuchamhembe akadai seYANG model, REST API, uye netconf, manejimendi yekutumira michina yeDCI uye manejimendi yeIP network zvinogadzirwa neinterface imwechete, kuitira kuti zviite zvirinani manejimendi yenetwork yakabatana yakavakirwa papuratifomu.
6. Kuvimbika kwakanyanya, nzira dzakawanda dzekufambisa mashoko uye matekinoroji ekudzivirira asingazive nezvechikamu chepamusoro acharamba achiita basa muDCI transmission network. Kukundikana padanho rekubatanidza hakufanirwe kukanganisa masevhisi kunze kwekunge kwakanganiswa zvachose. Kuona kana kukanganisa, kungave kuchinja kwekudzivirira, kusvetuka kwekubatanidza, kuwedzera kwekunonoka, nezvimwewo.
