Ukurikije ibyo biranga, hari ibisubizo bibiri bisanzwe DCI ibisubizo:
1. Koresha ibikoresho byiza bya DWDM, kandi ukoreshe ibara rya optique module + DWDM multiplexer / demultiplexer kuri switch.Kubireba umuyoboro umwe wa 10G, igiciro ni gito cyane, kandi ibicuruzwa birahari.10G ibara ryumucyo module iri murugo Byarakozwe, kandi ikiguzi kimaze kuba gito cyane (mubyukuri, sisitemu ya 10G DWDM yatangiye kumenyekana mumyaka mike ishize, ariko hamwe no kugera kubisabwa binini cyane, byari bifite kurandurwa, kandi 100G ibara ryamabara 100G yari itaraboneka. Kugaragara.) Kugeza ubu, 100G yatangiye kugaragara mubushinwa bijyanye na optique ya optique, kandi igiciro ntabwo kiri hasi bihagije, ariko bizahora bitanga umusanzu ukomeye. Kuri Umuyoboro wa DCI.
2. Koresha ibikoresho byinshi byohereza OTN, ni 220V AC, ibikoresho bya santimetero 19, hejuru ya 1 ~ 2U, kandi kubohereza biroroshye.Imikorere ya SD-FEC yazimye kugirango igabanye gutinda, kandi kurinda inzira kumurongo wa optique bikoreshwa mugutezimbere umutekano, kandi interineti ishobora kugenzurwa mumajyaruguru nayo itezimbere ubushobozi bwiterambere ryibikorwa byo kwagura ibikoresho.Nyamara, tekinoroji ya OTN iracyabitswe, kandi imiyoborere izakomeza kuba ingorabahizi.
Mubyongeyeho, ibyo abubaka umuyoboro wa mbere wa DCI murwego rwa mbere barimo gukora cyane cyane ni ugukuraho umuyoboro wa DCI wohereza, harimo gukuramo optique kuri layer 0 hamwe n’amashanyarazi kuri layer 1, hamwe na NMS nibikoresho byibyuma byabakora gakondo .gukuramo.Uburyo bwa gakondo ni uko ibikoresho bimwe na bimwe by’amashanyarazi bitunganya amashanyarazi bigomba gufatanya n’ibikoresho bimwe bya optique, kandi ibikoresho byuma bigomba gukorana na software ya NMS yihariye yo kuyobora.Ubu buryo gakondo bufite ibibi byinshi byingenzi:
1. Ikoranabuhanga rirafunzwe.Mubyigisho, urwego rwa optoelectronic rushobora gukurwaho hagati yabandi, ariko ababikora gakondo ntibacika nkana kugirango bagenzure ububasha bwikoranabuhanga.
2. Igiciro cyumuyoboro wa DCI wibanze cyane murwego rwo gutunganya ibimenyetso byamashanyarazi.Igiciro cyambere cyubwubatsi bwa sisitemu ni gito, ariko mugihe ubushobozi bwaguwe, uwabikoze azamura igiciro abangamiwe nubuhanga bwihariye, kandi ikiguzi cyo kwaguka kiziyongera cyane.
3. Nyuma yumurongo wa optique wumuyoboro wa DCI woherejwe ushyizwe mubikorwa, urashobora gukoreshwa gusa nibikoresho byamashanyarazi byumushinga umwe.Igipimo cyo gukoresha ibikoresho ibikoresho ni gito, kidahuye nicyerekezo cyiterambere cyumutungo woguhuza, kandi ntabwo bifasha guhuza ibikoresho bya optique byateganijwe.Igice cya optique cyashizwe muburyo butandukanye mugihe cyambere cyo kubaka, kandi ntabwo bigarukira kumikoreshereze yigihe kizaza ya sisitemu imwe ya optique igizwe nabakora inganda nyinshi, kandi igahuza intera yo mumajyaruguru ya optique hamwe na tekinoroji ya SDN kugirango ikore gahunda yicyerekezo. ibikoresho kurwego rwa optique, Kunoza ubucuruzi bworoshye.
4 gucunga imiyoboro.gucunga neza imikorere.
Kubwibyo, optoelectronic decoupling nicyerekezo gishya cyiterambere ryiterambere rya DCI.Mugihe kizaza, optique ya optique yumurongo wa DCI irashobora kuba tekinoroji ya SDN igizwe na ROADM + mumajyaruguru-yepfo, kandi umuyoboro urashobora gufungurwa, gutegurwa no kugarurwa uko bishakiye.Bizashoboka gukoresha ibikoresho bivanze byamashanyarazi bivangwa nababikora, cyangwa no kuvanga gukoresha interineti ya Ethernet hamwe na OTN kuri sisitemu imwe ya optique.Icyo gihe, imikorere ikora muburyo bwo kwagura sisitemu no guhinduka bizanozwa cyane, kandi optique nayo izakoreshwa.Biroroshye gutandukanya, imiyoboro ya logique imiyoborere irasobanutse, kandi ikiguzi kizagabanuka cyane.
Kuri SDN, intego yibanze nubuyobozi bukomatanyirijwe hamwe no kugabura umutungo wurusobe.None, ni ubuhe buryo bwo gukwirakwiza imiyoboro ya DWDM ishobora gucungwa kuri neti ya DCI yohereza?
Hano hari imiyoboro itatu, inzira, hamwe numuyoboro mugari (frequency).Kubwibyo, urumuri mubufatanye bwurumuri + IP mubyukuri bikorwa hafi yubuyobozi no gukwirakwiza izi ngingo uko ari eshatu.
Imiyoboro ya IP na DWDM yaciwemo kabiri, niba rero umubano uhuye hagati ya IP ihuza umuyoboro wa IP n'umuyoboro wa DWDM washyizweho mugihe cyambere, kandi isano ijyanye numuyoboro na IP igomba guhinduka nyuma, urashobora gukoresha OXC Uburyo bukoreshwa mugukora umuyoboro wihuse uhinduranya urwego rwa milisegonda, rushobora gutuma IP igabanuka.Binyuze mu micungire ya OXC, umutungo wibanze wo gucunga umuyoboro wogukwirakwiza kuri buri rubuga urashobora kugerwaho, kugirango ubufatanye nubucuruzi SDN.
Guhindura ibice byumuyoboro umwe na IP nigice gito gusa.Niba utekereza guhindura umurongo mugihe uhindura umuyoboro, urashobora gukemura ikibazo cyo guhindura umurongo mugari wa serivisi zitandukanye mubihe bitandukanye.Kunoza cyane igipimo cyo gukoresha umurongo wubatswe.Kubwibyo, mugihe uhuza na OXC kugirango uhindure umuyoboro, uhujwe na multiplexer na demultiplexer ya tekinoroji ya gride yoroheje, umuyoboro umwe ntukigifite umurongo uhoraho wo hagati, ariko uyemerera gupfundikanya intera nini, kugirango ugere kubintu byoroshye guhinduka. ingano yumurongo.Byongeye kandi, mugihe cyo gukoresha serivisi nyinshi murusobe rwa topologiya, igipimo cyo gukoresha inshuro za sisitemu ya DWDM kirashobora kurushaho kunozwa, kandi ibikoresho bihari birashobora gukoreshwa mukwuzura.
Hamwe nubushobozi bukomeye bwo kuyobora bwa bibiri byambere, inzira yo kuyobora imiyoboro yohereza irashobora gufasha imiyoboro yose ya topologiya kugira ituze ryinshi.Ukurikije ibiranga umuyoboro wogukwirakwiza, buri nzira ifite imiyoboro yigenga yigenga, bityo rero ni ngombwa cyane gucunga no kugabura imiyoboro kuri buri nzira yohererezanya muburyo bumwe, izatanga inzira nziza yo guhitamo inzira zinyuranye, kandi wongere ukoreshe imiyoboro yumutungo munzira zose.Nko muri ASON, zahabu, ifeza numuringa biratandukanye kubikorwa bitandukanye kugirango habeho ituze ryurwego rwo hejuru rwa serivisi.
Kurugero, hari umuyoboro wimpeta ugizwe nibice bitatu byamakuru A, B, na C. Hariho serivise S1 (nka intranet nini ya serivise nini), kuva A kugeza kuri B kugeza kuri C, ifata imiraba 1 ~ 5 yuru rusobe, buri muhengeri ufite umurongo wa 100G, kandi intera yumurongo ni 50GHz;hari serivisi S2 (serivise y'urusobekerane rwo hanze), Kuva A kugeza kuri B kugeza kuri C, 6 ~ 9 imiraba yuru rusobe rwimpeta irahari, buri muhengeri ufite umurongo wa 100G, kandi intera yumurongo ni 50GHz.
Mubihe bisanzwe, ubu bwoko bwumurongo numuyoboro ukoresha birashobora guhaza ibyifuzo, ariko mugihe rimwe na rimwe, urugero, ikigo gishya cyongeweho, kandi ubucuruzi bugomba kwimura data base mugihe gito, hanyuma igakenera umurongo wa intranet muri iki gihe kizaba Cyikubye kabiri, umwimerere wa 500G (5 100G), ubu bisaba umurongo wa 2T.Noneho imiyoboro yohereza irashobora kongera kubarwa, kandi imiyoboro itanu 400G yoherejwe murwego rwumuraba.Intera yumurongo wa buri muyoboro wa 400G ihindurwa kuva 50GHz yumwimerere ikagera kuri 75GHz.Hamwe noguhindura byoroshye ROADM na multiplexer / demultiplexer, inzira yose kurwego rwohereza, bityo iyi miyoboro itanu itwara ibikoresho bya 375GHz.Nyuma yuko ibikoresho biri murwego rwo kohereza byiteguye, hindura OXC unyuze kumurongo wubuyobozi bukomatanyije, hanyuma uhindure imiyoboro yohereza ikoreshwa numurongo wambere 1-5 wibimenyetso bya serivise 100G kuri 5 bishya byateguwe hamwe no gutinda kurwego rwa milisegonda. umuyoboro urazamuka, kugirango imikorere yo guhuza byoroshye umurongo numuyoboro ukurikije serivisi za DCI zisabwa zirangiye, zishobora gukorwa mugihe nyacyo.Birumvikana ko umuyoboro uhuza ibikoresho bya IP ukeneye gushyigikira igipimo cya 100G / 400G gishobora guhindurwa kandi cyerekana ibimenyetso bya optique (umurongo wa wavelength), ntabwo bizaba ikibazo.
Kubijyanye na tekinoroji ya neti ya DCI, umurimo ushobora kurangizwa no kohereza ni urwego rwo hasi cyane.Kugirango ugere kumurongo wubwenge DCI ufite ubwenge, bigomba kumenyekana hamwe na IP.Kurugero, koresha MP-BGP EVPN + VXLAN kuri IP intranet ya DCI kugirango uhite wohereza umuyoboro wa layer 2 kuri DCs, ushobora guhuzwa cyane nibikoresho byurusobe bihari kandi ugahuza ibikenewe byimashini zikodeshwa kugirango zigende neza muri DC.; Koresha ibice byanyuze kumurongo wa IP ya DCI kugirango ukore gahunda yumuhanda ushingiye kubitandukanya ubucuruzi, wujuje ibisabwa byambukiranya imipaka ya DC yerekana amashusho, kugarura inzira byihuse, no gukoresha umurongo mwinshi;imiyoboro ihererekanyabubasha ikorana na sisitemu ya OXC igizwe na sisitemu nyinshi, Ugereranije na ROADM isanzwe isanzwe, irashobora kumenya imikorere ya gahunda nziza ya gahunda yo gutegura gahunda;ikoreshwa ryikwirakwizwa ryumuriro utari umuyagankuba tekinoroji irashobora gukemura ikibazo cyo gucamo ibice umutungo wumuyoboro.Kwishyira hamwe kurwego rwo hejuru hamwe no hasi-umutungo wo gucunga no kohereza imishinga, kohereza byoroshye, no gukoresha neza umutungo bizaba icyerekezo byanze bikunze mugihe kizaza.Kugeza ubu, amasosiyete manini yo mu gihugu yitondera kariya gace, kandi ibigo bimwe na bimwe bitangiza imishinga isanzwe ikora ubushakashatsi no guteza imbere ibicuruzwa bya tekiniki bijyanye.Twizere ko tuzabona ibisubizo rusange bijyanye nisoko muri uyu mwaka.Ahari mugihe cya vuba, OTN nayo izashira mumiyoboro yabatwara-urwego, hasigara DWDM gusa.
