Dukurikije ibi biranga, hari ibisubizo bibiri bisanzwe bya DCI:
1. Koresha ibikoresho bya DWDM gusa, kandi ukoreshe module y'amabara + DWDM multiplexer/demultiplexer kuri switch. Ku bijyanye na 10G imwe, igiciro ni gito cyane, kandi amahitamo y'ibicuruzwa ni menshi. Module y'amabara ya 10G iri mu gihugu. Yamaze gukorwa, kandi igiciro cyayo kiri hasi cyane (mu by'ukuri, sisitemu ya 10G DWDM yatangiye gukundwa mu myaka mike ishize, ariko hamwe no kugera ku bisabwa byinshi bya bandwidth, byabaye ngombwa ko ikurwaho, kandi module y'amabara ya 100G ntiyari iraboneka. Yagaragaye.) Kuri ubu, 100G yatangiye kugaragara muri module z'amabara zijyanye n'Ubushinwa, kandi igiciro ntikiri hasi bihagije, ariko izahora igira uruhare rukomeye ku muyoboro wa DCI.
2. Koresha ibikoresho bya OTN bifite ubucucike bwinshi, bifite AC ya 220V, ibikoresho bya santimetero 19, uburebure bwa 1 ~ 2U, kandi uburyo bwo kubikoresha biroroshye cyane. Imikorere ya SD-FEC irazimye kugira ngo igabanye gutinda, kandi uburyo bwo kurinda inzira kuri optique layer bukoreshwa kugira ngo burusheho gutuza, kandi uburyo bwo kugenzura bugana mu majyaruguru nabwo bunongera ubushobozi bwo guteza imbere imikorere yo kwagura ibikoresho. Ariko, ikoranabuhanga rya OTN rirahari, kandi imicungire izakomeza kugorana.
Byongeye kandi, icyo abubatsi ba DCI bo mu cyiciro cya mbere bakora ubu ni ugutandukanya umuyoboro wa DCI, harimo no gukuramo imiyoboro y’amashanyarazi ku cyiciro cya 0 n’amashanyarazi ku cyiciro cya 1, ndetse no gukuramo imiyoboro ya NMS n’ibikoresho by’ibikoresho by’inganda gakondo. Uburyo gakondo ni uko ibikoresho by’amashanyarazi by’uruganda runaka bigomba gukorana n’ibikoresho by’amashanyarazi by’uruganda rumwe, kandi ibikoresho by’ibikoresho bigomba gukorana na porogaramu ya NMS y’uruganda bwite mu gucunga. Ubu buryo gakondo bufite ingorane nyinshi zikomeye:
1. Ikoranabuhanga rirafunze. Mu buryo bw'imitekerereze, urwego rwa optoelectronic rushobora gutandukanywa hagati yarwo, ariko abakora ibikoresho gakondo ntibatandukanywa nkana kugira ngo bagenzure ububasha bw'ikoranabuhanga.
2. Igiciro cy'umuyoboro wa DCI gikunze kwibanda ku buryo bwo gutunganya ibimenyetso by'amashanyarazi. Igiciro cy'ibanze cy'ubwubatsi bw'iyi sisitemu ni gito, ariko iyo ubushobozi bwongewe, uruganda ruzamura igiciro bitewe n'uko budasa neza mu buryo bwa tekiniki, kandi ikiguzi cyo kwagura kiziyongera cyane.
3. Nyuma yuko urwego rw'amashanyarazi rwa DCI rushyizwe mu bikorwa, rushobora gukoreshwa gusa n'ibikoresho by'amashanyarazi by'uruganda rumwe. Igipimo cy'ikoreshwa ry'ibikoresho ni gito, kidahuye n'icyerekezo cy'iterambere ry'umutungo w'urusobe rw'amashanyarazi, kandi ntigifasha mu gutegura gahunda y'umutungo w'amashanyarazi. Urwego rw'amashanyarazi rutandukanye rushyirwa ukwarwo mu ntangiriro z'ubwubatsi, kandi ntirugengwa no gukoresha sisitemu imwe y'urwego rw'amashanyarazi mu gihe kizaza n'inganda nyinshi, kandi ruhuza urwego rw'amashanyarazi rugana mu majyaruguru n'ikoranabuhanga rya SDN kugira ngo rukore gahunda y'icyerekezo cy'umutungo w'amashanyarazi kuri urwo rwego rw'amashanyarazi, kunoza ubwisanzure bw'ubucuruzi.
4. Ibikoresho by'umuyoboro bihuza neza na platforme y'ikigo cya interineti binyuze mu miterere y'amakuru ya YANGmodel, ibi bikaba bizigama ishoramari mu iterambere ry'urubuga rw'imicungire kandi bigakuraho porogaramu ya NMS itangwa n'uwakoze, ibi bikaba binoza imikorere myiza yo gukusanya amakuru no gucunga umuyoboro.
Kubwibyo, gucana umurongo wa optoelectronic ni icyerekezo gishya cyo guteza imbere umuyoboro wa DCI. Mu gihe kiri imbere, urwego rw'ikoranabuhanga rwa DCI rushobora kuba ikoranabuhanga rya SDN rigizwe na ROADM+ umurongo wa ROADM+ wo mu majyaruguru-amajyepfo, kandi umuyoboro ushobora gufungurwa, gutegurwa no kugaruzwa uko ubyishakiye. Bizashoboka gukoresha ibikoresho by'amashanyarazi bivanze by'abakora, cyangwa se gukoresha imiyoboro ya Ethernet na OTN kuri sisitemu imwe ya optique. Muri icyo gihe, imikorere myiza mu bijyanye no kwagura no guhindura sisitemu izarushaho kuba myiza, kandi urwego rw'ikoranabuhanga ruzakoreshwa. Biroroshye gutandukanya, imicungire ya network logic irasobanutse neza, kandi ikiguzi kizagabanuka cyane.
Kuri SDN, intego nyamukuru ni imicungire rusange n'igabanywa ry'umutungo w'imiyoboro. None se, ni iyihe miyoboro ya DWDM ishobora gucungwa kuri DCI transmission network iriho ubu?
Hari imiyoboro itatu, inzira, n'umuyoboro w'itumanaho (frequency). Kubwibyo, urumuri mu bufatanye bw'urumuri + IP rukorwa mu buryo bujyanye no gucunga no gukwirakwiza izi ngingo eshatu.
Imiyoboro ya IP na DWDM iratandukanye, bityo niba isano iri hagati y’umurongo wa IP logical link n’umuyoboro wa DWDM yashyizweho mu ntangiriro, kandi isano iri hagati y’umuyoboro na IP igomba guhindurwa nyuma, ushobora gukoresha uburyo bwa OXC bukoreshwa mu guhindura imiyoboro vuba ku rwego rwa milisegonda, bishobora gutuma urwego rwa IP rutamenyekana. Binyuze mu micungire ya OXC, imicungire y’umutungo w’umuyoboro wo kohereza amakuru kuri buri rubuga irashobora kugerwaho, kugira ngo ikorane na SDN y’ubucuruzi.
Guhindura umurongo umwe na IP ni igice gito cyane. Iyo utekereje guhindura umurongo mu gihe uhindura umurongo, ushobora gukemura ikibazo cyo guhindura ibisabwa kuri interineti ya serivisi zitandukanye mu bihe bitandukanye. Kunoza cyane umuvuduko w'ikoreshwa ry'umurongo mugari wubatswe. Bityo, mu gihe uhuza na OXC kugira ngo uhindure umurongo, hamwe na multiplexer na demultiplexer by'ikoranabuhanga rya flexible grid, umurongo umwe ntuba ugifite uburebure bw'umurambararo buhamye hagati, ahubwo utuma ugera ku rugero rw'umuvuduko rushobora kwaguka, kugira ngo ugere ku gukosora guhindagurika kw'ingano ya interineti. Byongeye kandi, mu gihe cyo gukoresha serivisi nyinshi muri topology y'umuyoboro, umuvuduko w'ikoreshwa rya sisitemu ya DWDM ushobora kunozwa kurushaho, kandi umutungo uhari ushobora gukoreshwa mu gukwirakwiza.
Bitewe n'ubushobozi bwo gucunga ibintu bugaragara nk'ubwo mu buryo bubiri bwa mbere, imicungire y'inzira z'umuyoboro w'itumanaho ishobora gufasha imiterere y'umuyoboro wose kugira umutekano mwinshi. Dukurikije imiterere y'umuyoboro w'itumanaho, buri nzira ifite umutungo wigenga w'itumanaho, bityo ni ingenzi cyane gucunga no gushyira imiyoboro kuri buri nzira y'itumanaho mu buryo bumwe, bizatanga uburyo bwiza bwo guhitamo inzira z'itumanaho ku nzira nyinshi, no gukoresha neza umutungo w'itumanaho ku nzira zose. Kimwe na ASON, zahabu, feza n'umuringa biratandukanye kubera serivisi zitandukanye kugira ngo serivisi zo ku rwego rwo hejuru zihamye.
Urugero, hari umuyoboro w'impeta ugizwe n'ibigo bitatu by'amakuru A, B, na C. Hari serivisi S1 (nk'isosiyete ya intranet big data service), kuva kuri A kugeza kuri B kugeza kuri C, ifata imiraba 1 ~ 5 y'uyu muyoboro w'impeta, buri muyoboro ufite umurambararo wa 100G, kandi intera y'impeta ni 50GHz; hari serivisi S2 (isosiyete yo hanze y'umuyoboro), Kuva kuri A kugeza kuri B kugeza kuri C, imiraba 6 ~ 9 y'uyu muyoboro w'impeta irakoreshwa, buri muyoboro ufite umurambararo wa 100G, naho intera y'impeta ni 50GHz.
Mu bihe bisanzwe, ubu bwoko bwa bandwidth n'ikoreshwa ry'imiyoboro bishobora guhaza icyifuzo, ariko iyo rimwe na rimwe, urugero, ikigo gishya cy'amakuru cyongewemo, maze ubucuruzi bugakenera kwimura ububiko bw'amakuru mu gihe gito, icyo gihe icyifuzo cya bandwidth ya intranet muri iki gihe kizaba cyikubye kabiri, bandwidth ya 500G ya mbere (5 100G), ubu ikeneye bandwidth ya 2T. Hanyuma imiyoboro iri ku rwego rwo kohereza ishobora kongera kubarwa, maze imiyoboro itanu ya 400G ishyirwa mu cyiciro cy'umuraba. Intera y'inshuro ya buri muyoboro wa 400G ihinduka kuva kuri 50GHz ya mbere ikagera kuri 75GHz. Hamwe na ROADM ihindura imiterere na multiplexer/demultiplexer, inzira yose ku rwego rwo kohereza, bityo iyi miyoboro itanu ifata umutungo wa spectrum ya 375GHz. Nyuma y’uko ibikoresho byo ku rwego rwo kohereza amakuru biteguwe, hindura OXC unyuze kuri platform yo gucunga amakuru, hanyuma uhindure imiyoboro yo kohereza amakuru ikoreshwa n’imiraba ya mbere ya 1-5 y’ibimenyetso bya serivisi ya 100G kuri 5 bishya byateguwe hamwe n’ubukererwe bwa milisegonda. Umuyoboro wa serivisi wa 400G urazamuka, kugira ngo akazi ko guhindura bandwidth na channel hakurikijwe ibisabwa na serivisi ya DCI karangire, ibyo bikaba bishobora gukorwa mu gihe nyacyo. Birumvikana ko imiyoboro y’itumanaho ry’ibikoresho bya IP igomba gushyigikira imikorere yo guhindura 100G/400G rate adjustable na optical signal frequency (wavelength), ibyo ntibizaba ikibazo.
Ku bijyanye n'ikoranabuhanga rya DCI mu miyoboro, akazi gashobora kurangizwa no kohereza amakuru ni urwego rwo hasi cyane. Kugira ngo ugere ku muyoboro wa DCI w’ubwenge, ugomba gukorwa hamwe na IP. Urugero, koresha MP-BGP EVPN+VXLAN kuri intranet ya IP ya DCI kugira ngo wohereze vuba umuyoboro wa 2 kuri DC, ushobora guhuza cyane n'ibikoresho bya network bihari kandi ugahura n'ibyo imashini zikora zikenera kugira ngo zigende neza muri DC. ; Koresha uburyo bwo gukwirakwiza amakuru kuri DCI's segment routing external network kugira ngo ukore gahunda y'inzira z'umuhanda hashingiwe ku itandukaniro ry'ubucuruzi, wujuje ibisabwa byo kwerekana inzira za DC, gusana inzira byihuse, no gukoresha bandwidth nyinshi; umuyoboro w'itumanaho ukorana na sisitemu ya OXC ifite imiterere myinshi, ugereranije na ROADM isanzweho, ishobora gukora imikorere myiza yo guteganya inzira; gukoresha ikoranabuhanga ryo guhindura uburebure bw'umuyoboro wa transmission ritari amashanyarazi bishobora gukemura ikibazo cyo gucikamo ibice by'umutungo wa channel spectrum. Guhuza umutungo wo hejuru n'uwo hasi mu gucunga no gushyiraho ubucuruzi, gushyiraho uburyo bworoshye, no kunoza imikoreshereze y'umutungo bizaba icyerekezo kidasubirwaho mu gihe kizaza. Kuri ubu, amwe mu masosiyete manini yo mu gihugu arimo kwita kuri iki gice, kandi amwe mu masosiyete yihariye y’inganda atangiye gukora ubushakashatsi no guteza imbere ibikoresho bya tekiniki bifitanye isano. Nizeye kubona ibisubizo bifitanye isano muri rusange ku isoko uyu mwaka. Wenda mu gihe cya vuba aha, OTN nayo izashira mu miyoboro y’itumanaho, hagasigara DWDM gusa.
