Iyo ba nyiri data center bubatse imiyoboro ihuza imiyoboro ihuza imiyoboro, batekereza cyane cyane kubibazo nkumuyoboro mugari, ubukererwe buke, ubucucike bukabije, kohereza vuba, gukora byoroshye no kubungabunga, kandi byizewe cyane.Kugeza ubu, imiyoboro minini nini ya tekinoroji ya OTN igenzurwa cyane n’inganda nini nini nini zikoresha ibikoresho byitumanaho (chip zaganiriweho ukundi), nka Huawei, ZTE, na Aran.Abakiriya nyamukuru bahura nazo ni abakoresha itumanaho gakondo, bityo ibicuruzwa biranga OTN bigenewe ahanini guhuza serivisi ziranga aba bakora.Kubera iyi, OTN irakoreshwa cyane mubikorwa bya DCI murusobe rwa interineti.Ibibazo byinshi bidahuye.
Ibiranga ibikoresho bya OTN nibibazo bimwe na bimwe byahuye na DCI, ubucuruzi bukize hejuru, ubushobozi bukomeye bwa OAM bwurusobe, guteganya no kugwiza ubushobozi bwumurongo utandukanye wa granular, kwihanganira amakosa kumurongo mugihe kirekire, no gukoresha voltage nkeya ikigezweho.Ibiranga nkigipimo gito cyo gukoresha ingufu zikoreshwa mubikoresho.
1. Ubushobozi bukoreshwa mubucuruzi busaba abakozi ba O&M kuba abanyamwuga, kwishingikiriza cyane kubufasha bwa tekiniki butangwa nababikora, kandi bafite tekinoroji ifunze.
2. Ubushobozi bukomeye bwa OAM, ibipimo bidahuye, bigoye cyane kandi byigenga guhuza imiyoboro ihuza imiyoboro, hamwe nibikorwa bidafite akamaro nabyo bizana amafaranga menshi yo kohereza no gukora kumurongo wa DCI.
3. Ubushobozi butandukanye bwa gahunda ya granule ituma serivise ya encapsulation yimiterere igizwe na complexe kandi byite byite.
4. Kwihanganira intera ndende kwihanganira amakosa bituma FEC algorithm igorana, ikoresha byinshi hejuru kandi bifata igihe kinini kugirango ikorwe
5. Uburyo bwa 48V-DC bwo gutanga amashanyarazi yibikoresho bya OTN butandukanye nububiko busanzwe bwa santimetero 19 220V-AD (cyangwa 240V-DC) bwakoreshejwe mubigo byinshi byamakuru.Kwiyubaka biragoye kandi bisaba guhindura ingufu mubyumba bya mudasobwa
6. Ibikoresho gakondo bya OTN bifite ikadiri nini, idakwiriye gushyirwaho mumabati asanzwe, kandi ubwinshi bwubushobozi ntabwo buri hejuru.Nyuma kwaguka biragoye kandi bisaba akabati kwimurwa cyangwa kwiyubaka.
Kugeza ubu, umuyoboro wa DCI ni ugutanga cyane cyane imiyoboro yamakuru hagati yamakuru.Ibintu nyamukuru biranga icyitegererezo cyubucuruzi ni: guhuriza hamwe hamwe umurongo umwe wa granularity ibisabwa, umurongo mugari, serivisi zambukiranya amakuru (cyane cyane IDC ikora cyane, serivisi nini cyane)icyarimwe, kubera kubura abakozi babigize umwuga nubuhanga mubikorwa bya interineti, imikorere no gufata neza imiyoboro ya DCI bigomba kuba "byoroshye" "byoroshye" na "byoroshye" - ibintu byingenzi bivugwa inshuro eshatu (aho Isn 'ntabwo ari ubwoko bw'urusobe?);iterambere riturika rya interineti rituma ibyubaka byubaka no kwaguka bigufi bigufi (abakoresha OTN yo kwaguka muri rusange ni igice cyumwaka kugeza kumwaka umwe, mugihe interineti yonyine DCI yo kwagura ari amezi 1 kugeza 3), Kubwibyo, birakenewe guhagarika igihe muri byose.
Kubwibyo, OTN itanga igisubizo cyakoreshwa kuri DCI, ariko OTN ntabwo aribwo buryo bukwiye kuri DCI.Noneho umuyoboro wa DCI uratera imbere, haracyakenewe ibisubizo bimwe bikwiye kugirango bikemure ibibazo kuva kubiciro kugeza kubaka, gukora no kubungabunga.ibibazo bitandukanye byahuye nabyo.Kandi ibyo bibazo ntakindi kirenze ibintu bitandatu bisabwa murusobe rwa DCI (umurongo mugari, umuvuduko muke, ubucucike bukabije, kohereza vuba, gukora byoroshye no kubungabunga, no kwizerwa cyane):
1. Umuyoboro munini, umuyoboro wa DCI udafite ubwoko bwinshi bwa granules nkabakora, umurongo wa granules wumuyoboro wa DCI woroheje uroroshye, kuri ubu usanzwe ukoreshwa 10G cyangwa 100G, mugihe kizaza 200G / 400G, nibindi, ntabwo rero bikenewe. kubikora hamwe numuyoboro munini Umuyoboro mugari kuri granularities.Bitewe nuko intera yumurongo wogukwirakwiza DCI mubusanzwe atari ndende cyane, ukoresheje sisitemu ya 400G ishingiye kuri 200G PM-16QAM ihinduranya-itwara ibintu bibiri, intera yoherejwe idafite amashanyarazi irashobora kuba kilometero 500 (PM-64QAM ni hafi kilometero 200), kugirango metro umugongo wohereza DCI ntuzagarukira ku ntera.
2. Ubukererwe buke, DCI ibisabwa mubucuruzi, cyane cyane iyo comptabilite ikoreshwa muguhuza umutungo hamwe namakuru menshi yibikorwa, amakuru yatinze abarwa kurwego rwa microsecond, bityo igihe cyo kohereza amakuru kigomba kuba kigufi gishoboka, wifuza kurenga kuri umuvuduko w'urumuri.Kuraho imirimo idakenewe yo gutunganya amakuru no kugabanya inzira zo kohereza ibimenyetso.Kurugero, mugukuraho imikorere ya SD-FEC ikoreshwa na 100G OTN, umugongo umwe-winyuma urashobora kuzigama microseconds 200, no gukuraho urwego rwambukiranya OTN rushobora kuzigama microseconds, kandi ugakoresha neza topologiya ya hubspoke kubikorwa byingenzi. kwemeza inzira ngufi.Birumvikana, irashobora kandi gufatanya na MPLS na QOS kurwego rwa IP kugirango igerageze kwemeza ko gutinda kurwego rwo kohereza amakuru nabyo ari byiza.
3.Ubucucike buri hejuru, U imwe, cyangwa 2U, burashobora kugera kumurongo mugari wa T, DWDM optique hamwe na signal ya elegitoronike yerekana amashanyarazi, kunoza intera yubucucike bwibikoresho, no kugabanya ubunini bwa module optique.Kurugero, ikoreshwa rya QSFP28 optique irashobora kwemeza ko ubushobozi bwa 100G bwo kubona igikoresho kimwe bwateye imbere cyane, kandi gukoresha moderi ya CFP2 kumurika kumurongo kuruhande birashobora kwemeza ko umurongo wogukwirakwiza wigikoresho rusange utezimbere, 1U irashobora kuba 1.6T, 3.2T.Kugeza ubu, ibicuruzwa byinshi bifitanye isano byagaragaye ku isi, nka ADVA, coriant, ciena n'andi masosiyete.Nibyo, Huawei yo murugo nayo yashyize ahagaragara ibicuruzwa 902 bijyanye.Ariko, kugeza iyi ngingo irangiye, birasa nkaho ikizamini cyo kubona imiyoboro ya minisiteri yinganda n’ikoranabuhanga mu itumanaho kitarangiye.Ubucucike bwinshi buzatera ingufu nyinshi no gukwirakwiza ubushyuhe.Kubwibyo, uburyo bwambere bwo gukwirakwiza ubushyuhe bwa OTN bwumuyaga wibumoso nu buryo bwimbere no hanze, kandi hejuru no hepfo umwuka winjira no hanze bigomba gutabwa.
Ibisabwa byo gukonjesha ibikoresho.
4. Kohereza byihuse, ukoresheje IDC isanzwe igezweho ya santimetero 19, bisa nuburyo bwa seriveri nyamukuru, ukoresheje AC-220V mugutanga amashanyarazi ataziguye, bikuraho ingufu zikenewe no guhindura guverinoma, no kumenya ko ibicuruzwa bishobora gushyirwaho. amasahani ako kanya bamaze kugera mucyumba cya mudasobwa, kandi irashobora gushyirwaho nyuma yo gucomeka mumashanyarazi.ubucuruzi, kandi ukore akazi keza mubikorwa bisanzwe byo kwemerwa kugirango ugere kubyoherejwe byihuse.
5. Gukora no kubungabunga byoroshye, ibyifuzo byubucuruzi bwa DCI, intera iri hagati yikigo ntizaba kure cyane, kandi imiyoborere igoye, OAM nindi mirimo ntabwo ikenewe kugirango igire uruhare runini muriki gihe, kandi gutunganya ibintu nabyo biragabanuka Itezimbere uburyo bwo kohereza amakuru, itezimbere igihe cyo gutunganya amakuru, kandi ifite ibisabwa byinshi mubuhanga kandi irafunzwe.Guhuza ibimenyetso biturutse kuri Ethernet bikuraho hejuru ya OTN igoye, bityo abashoramari ba IP gakondo barashobora gukora no kubungabunga sisitemu ya DCI.Nyuma yo guhuza ibice bishya byamajyaruguru nka YANG moderi, REST API, na netconf, gucunga ibikoresho byohereza DCI hamwe no gucunga ibikoresho bya neti ya IP byatejwe imbere hamwe, kugirango birusheho gukora neza uburyo bumwe bushingiye kumurongo uhuza imiyoboro.
6. Kwizerwa cyane, inzira-yumubiri myinshi hamwe nubuhanga bwo kurinda butazi urwego rwo hejuru bizakomeza kugira uruhare mumiyoboro ya DCI.Kunanirwa kurwego rwihuza ntirugomba kugira ingaruka kuri serivisi keretse iyo byahagaritswe burundu.Imyumvire cyangwa ingaruka, niba ari uguhindura kurinda, guhuza jitter, gutinda kwiyongera, nibindi.
