Iyo ba nyiri ikigo cy’amakuru bubaka imiyoboro y’amakuru, batekereza cyane cyane ku bibazo nka bandwidth nini, gutinda guke, ubucucike bwinshi, kohereza vuba, koroshya imikorere no kubungabunga, ndetse no kwizerwa cyane. Muri iki gihe, ikoranabuhanga rikuru rya OTN rigenzurwa ahanini n’inganda nyinshi nini zikora ibikoresho by’itumanaho (utuntu duto dusobanurwa ukwatwo), nka Huawei, ZTE, na Aran. Abakiriya bakomeye bahura na bo ni abakora itumanaho gakondo, bityo imiterere y’ibicuruzwa bya OTN igamije cyane cyane guhuza imiterere ya serivisi z’aba bakora. Kubera iyo mpamvu, OTN ikoreshwa cyane muri porogaramu za DCI mu nganda za interineti. Ibibazo byinshi bivuguruzanya.
Ibiranga ibikoresho bya OTN ni bimwe na DCI, ubucuruzi bwinshi, ubushobozi bukomeye bwa OAM bw'umuyoboro, ubushobozi bwo guteganya no gukwirakwiza bandwidth zitandukanye, ubushobozi bwo kwihanganira amakosa y'umurongo mu gihe cy'intera ndende, hamwe n'ikoreshwa ry'umuriro w'amashanyarazi ufite voltage nke. Ibiranga nko gukoresha ingufu nke mu bikoresho.
1. Ubushobozi bwinshi bwo gukoresha amafaranga mu bucuruzi busaba abakozi ba O&M kuba abanyamwuga kurushaho, kwishingikiriza cyane ku bufasha bwa tekiniki buturuka ku nganda, no kugira ikoranabuhanga rifunze cyane.
2. Ubushobozi bukomeye bwa OAM, amahame adahuye, guhuza bigoranye kandi byigenga n'imiyoboro ihuza itumanaho, hamwe n'imikorere idafashije nabyo bizana ikiguzi cyo kohereza no gukora kuri umuyoboro wa DCI.
3. Ubushobozi butandukanye bwo guteganya granule butuma imiterere ya frame ya service encapsulation irushaho kugorana kandi ikaba ifite bytes nyinshi.
4. Uburyo bwo kwihanganira amakosa yo mu murongo muremure butuma algorithm ya FEC iba ikomeye, itwara amafaranga menshi kandi igafata igihe kirekire kuyitunganya
5. Uburyo bwo gutanga amashanyarazi bwa 48V-DC bw'ibikoresho bya OTN butandukanye n'ubusanzwe bwa santimetero 19 za 220V-AD (cyangwa 240V-DC) bukoreshwa mu bigo byinshi by'amakuru. Gushyiramo biragoye kandi bisaba guhindura amashanyarazi mu cyumba cya mudasobwa.
6. Ibikoresho bisanzwe bya OTN bifite urufatiro runini, rutakwiriye gushyirwa mu makabati asanzwe, kandi ubucucike bw'ubushobozi ntabwo buri hejuru. Kwagura nyuma biragorana kandi bisaba ko amakabati yimurwa cyangwa akongera kubakwa.
Muri iki gihe, umuyoboro wacu wa DCI ugamije cyane cyane gutanga inzira zo gukoresha amakuru ajyanye n’aho ukorera. Ibiranga ubucuruzi ni ibi bikurikira: ibisabwa kugira ngo bandwidth ihuzwe n’iy’umuyoboro umwe, bandwidth nini, serivisi z’aho ukorera amakuru ajyanye n’igihe (cyane cyane IDC ikora cyane, serivisi z’amakuru manini)) bifite ibisabwa bike byo gutinda no gukenera cyane kugira ngo umuyoboro uhamye; icyarimwe, bitewe n’uko nta bakozi b’inzobere n’abatekinisiye bakenewe mu nganda za interineti, imikorere n’imicungire y’imiyoboro ya DCI bigomba kuba “byoroshye” “byoroshye” kandi “byoroshye” – ibintu by’ingenzi bivugwa inshuro eshatu (aho si ubwoko bw’umuyoboro?); iterambere rikomeye rya interineti rituma ibisabwa mu kubaka no kwagura umuyoboro bigabanuka (umuyoboro wa OTN w’abakora muri rusange uba hagati y’igice cy’umwaka n’umwaka umwe, mu gihe ibisabwa mu kwagura umuyoboro wa DCI ari hagati y’ukwezi 1 na 3), bityo rero, ni ngombwa gukanda igihe muri byose.
Bityo rero, OTN itanga igisubizo gikwiye kuri DCI, ariko OTN ntabwo ari yo gisubizo gikwiye cyane kuri DCI. Ubu ko umuyoboro wa DCI uri gutera imbere, hari hakenewe ibisubizo bikwiye byo gukemura ibibazo bitandukanye kuva ku giciro kugeza ku bwubatsi, imikorere no kubungabunga. Ibibazo bitandukanye byagaragaye. Kandi ibi bibazo nta kindi uretse ibisabwa bitandatu bya DCI (umuyoboro munini w'itumanaho, gutinda guke, ubucucike bwinshi, gukwirakwiza vuba, koroshya imikorere no kubungabunga, no kwizerwa cyane):
1. Umuyoboro munini w’itumanaho rya DCI ntugira ubwoko bwinshi bw’udupira nk’abakoresha, udupira tw’umurongo w’itumanaho rya DCI tworoshye, ubu dukoreshwa cyane muri 10G cyangwa 100G, mu gihe kizaza 200G/400G, nibindi, bityo nta mpamvu yo kubikora hamwe n’umuyoboro munini w’itumanaho rya bandwidth ku bindi bice. Bitewe n’uko intera y’umuyoboro w’itumanaho rya DCI muri rusange atari ndende cyane, hakoreshejwe sisitemu ya 400G ishingiye kuri modulation ya 200G PM-16QAM itwara abantu babiri, intera yo kohereza ubutumwa idafite relay y’amashanyarazi ishobora kuba kilometero 500 (PM-64QAM ni kilometero 200), kugira ngo DCI itazagengwa n’intera.
2. Gutinda guke, ibisabwa na DCI mu bucuruzi, cyane cyane iyo ikoranabuhanga rya "cloud computing" rikoreshwa mu guhuza umutungo n'amakuru menshi, gutinda kubarwa ku rwego rwa microsecond, bityo igihe cyo kohereza amakuru kigomba kuba gito cyane, cyifuza kurenza umuvuduko w'urumuri. Kuraho akazi ko gutunganya amakuru kadakenewe no kugabanya inzira zo kohereza ibimenyetso. Urugero, mu gukuraho uburyo bwa SD-FEC bukoreshwa na 100G OTN, gukurura inshuro imwe inyuma bishobora kuzigama microsegonda 200, kandi gukuraho OTN encapsulation yo ku rwego rwa cross-level bishobora kuzigama microsegonda mirongo, kandi bigakoresha neza topology ya hubpoke kuri serivisi z'ingenzi kugira ngo inzira ibe ngufi. Birumvikana ko ishobora kandi gukorana na MPLS na QOS ku rwego rwa IP kugira ngo igerageze kwemeza ko gutinda ku rwego rwo kohereza amakuru nabyo ari byiza kurushaho.
3.Ubucucike bwinshi, U imwe, cyangwa 2U, bishobora kugera ku bucucike bugera kuri T, DWDM optical layer na electrical signal layer decoupling, kunoza urwego rw'ubucucike bw'igikoresho, no kugabanya ingano ya module optical. Urugero, gukoresha module optical za QSFP28 bishobora gutuma ubushobozi bwo kugera kuri 100G bw'igikoresho kimwe burushaho kuba bwiza, kandi gukoresha module za CFP2 dayning ku ruhande rw'umurongo bishobora gutuma bandwidth yo kohereza igikoresho muri rusange irushaho kuba nziza, 1U ishobora kuba 1.6T, 3.2T. Kuri ubu, hari ibicuruzwa byinshi bifitanye isano byagaragaye ku isi, nka ADVA, coriant, ciena n'ibindi bigo. Birumvikana ko Huawei yo mu gihugu nayo yatangije ibicuruzwa 902 bifitanye isano. Ariko, kugeza ku musozo w'iyi nkuru, bisa nkaho ikizamini cyo kugera kuri interineti cya Minisiteri y'Inganda n'Ikoranabuhanga mu Itangazamakuru kitararangira. Ubucucike bwinshi buzatuma ingufu zikoreshwa cyane kandi ubushyuhe bugashira. Bityo rero, uburyo bwa mbere bwo gukwirakwiza ubushyuhe bwa OTN, aho umwuka w’ibumoso n’iburyo winjira kandi usohoka, n’umwuka wo hejuru no hasi winjira kandi usohoka, bugomba gutabwa.
Ibisabwa mu gukonjesha igikoresho.
4. Gukoresha vuba, hakoreshejwe uburyo bwa IDC busanzwe bwa santimetero 19, nk'uko bimeze kuri seriveri zisanzwe, gukoresha AC-220V mu gutanga amashanyarazi mu buryo butaziguye, bikuraho gukenera guhindura amashanyarazi n'akabati, no kumenya ko ibicuruzwa bishobora gushyirwa ku bubiko ako kanya nyuma yuko bigeze mu cyumba cya mudasobwa, kandi bishobora gushyirwaho nyuma yo gushyiramo amashanyarazi. ubucuruzi, no gukora akazi keza mu mirimo isanzwe yo kwakira amashanyarazi kugira ngo bigere ku buryo bwihuse.
5. Gukoresha no kubungabunga byoroshye, ibisabwa muri DCI, intera hagati y’ibigo by’amakuru ntabwo izaba iri kure cyane, kandi imicungire igoye, OAM n’izindi nshingano ntabwo ari ngombwa kugira uruhare runini muri iki kibazo, kandi gutunganya ibintu bigoye nabyo biragabanuka. Binoza imikorere myiza yo kohereza amakuru, binoza igihe cyo gutunganya amakuru, kandi bifite ibisabwa byinshi mu ikoranabuhanga kandi bifunga cyane. Guhuza ibimenyetso binyuze kuri Ethernet bikuraho imikorere igoye ya OTN, bityo abahanga ba IP network basanzwe bashobora gukoresha no kubungabunga sisitemu ya DCI. Nyuma yo guhuza imiyoboro mishya igana mu majyaruguru nka YANG model, REST API, na netconf, imicungire y’ibikoresho byo kohereza DCI n’imicungire y’ibikoresho bya IP network birakorwa hamwe na interface imwe, kugira ngo birusheho gukora neza imicungire y’imiyoboro ihuriweho ishingiye kuri platform.
6. Ikoranabuhanga ryizewe cyane, rikoresha uburyo bwinshi bwo kunyuramo no kurinda ikoranabuhanga ritazi urwego rwo hejuru rizakomeza kugira uruhare mu muyoboro wa DCI. Kunanirwa ku rwego rw'ibanze rw'umuyoboro ntibigomba kugira ingaruka kuri serivisi keretse bihagaritswe burundu. Kubona cyangwa ingaruka, byaba ari uguhindura uburinzi, gutinda kw'umuyoboro, kwiyongera kw'igihe cyo gutinda, nibindi.
