Nyuma yuko umuyoboro wa DCI utangije tekinoroji ya OTN, bihwanye no kongeramo igice cyose cyakazi kitariho mbere mubijyanye nigikorwa.Umuyoboro gakondo wa data center ni umuyoboro wa IP, uri muburyo bwa tekinoroji yumurongo.OTN muri DCI ni tekinoroji yumubiri igaragara, nuburyo bwo gukorana na IP layer muburyo bwa gicuti kandi bworoshye ninzira ndende yo gukora.
Kugeza ubu, intego yibikorwa bishingiye kuri OTN ni kimwe na buri sisitemu yo muri data center.Byose bigamije kongera imbaraga mumikoreshereze yishoramari mubikorwa remezo bihenze no gutanga inkunga nziza kuri serivise zo hejuru.Kunoza ituze rya sisitemu shingiro, koroshya imikorere nogukora neza, gufasha mukugabana umutungo neza, gutuma umutungo ushora ugira uruhare runini, no kugabura umutungo udashoramari muburyo bukwiye.
Imikorere ya OTN ikubiyemo ibice byinshi: gucunga amakuru yimikorere, gucunga umutungo, gucunga iboneza, gucunga impuruza, gucunga imikorere, no kuyobora DCN.
1 Amakuru yimikorere
Kora imibare kumibare yamakosa, gutandukanya amakosa yabantu, amakosa yibikoresho, amakosa ya software, hamwe nandi makosa yabandi, kandi ukore isesengura ryibarurishamibare ku bwoko bwamakosa menshi, utegure gahunda yo gutunganya, kandi utange inzira yo gutunganya mu buryo bwikora amakosa nyuma yigihe kizaza .Ukurikije isesengura ryamakuru yamakosa, sisitemu itezimbere kubikorwa bizaza nko gushushanya imyubakire no guhitamo ibikoresho, kugirango bigabanye ibiciro byakazi nyuma yo gukora no kubungabunga.Kuri OTN, kora imibare yamakosa uhereye kuri optique ya optique, ikibaho, modules, multiplexers, gusimbuka ibikoresho, gusimbuka ibyuma, imiyoboro ya DCN, nibindi, witabire ibipimo byabashinzwe gukora, ibipimo byabandi, nibindi, kandi ukore amakuru menshi. gusesengura amakuru yukuri.Irashobora kwerekana neza uko ibintu bimeze.
Kora imibare kubyerekeranye nimpinduka, gutandukanya ingorane ningaruka zimpinduka, kugenera abakozi, no guhindura ibintu ukurikije inzira yo gusesengura ibyifuzo, gahunda yo guhindura, gushiraho idirishya, kumenyesha abakoresha, gukora ibikorwa, no gusubiramo incamake, hanyuma urashobora gukora impinduka zitandukanye Igabanijwemo Windows, ndetse itunganijwe kugirango ikorwe kumanywa, kugirango igabanywa ryabakozi rihindurwe neza, kugabanya umuvuduko wakazi nubuzima, no kuzamura umunezero wa ba injeniyeri bakora.Irashobora kandi guhuza amakuru yanyuma y'ibarurishamibare no kuyakoresha nk'urwego rwo gukora neza abakozi n'ubushobozi bw'akazi.Mugihe kimwe, iremera kandi impinduka zisanzwe gutera imbere mubyerekezo bisanzwe no kwikora, kugabanya amafaranga atandukanye.
Kusanya imibare kuri serivise ya OTN kugirango igufashe kumenya neza imikoreshereze y'urusobekerane no kugenzura imiyoboro rusange yo gukwirakwiza no gukwirakwiza serivisi nyuma yubucuruzi bwiyongereye.Niba ubikora nabi, urashobora kumenya serivise yumurongo umuyoboro umwe ukoresha, nkumuyoboro wo hanze, intranet, umuyoboro wa HPC, umuyoboro wa serivise, nibindi. Niba ubikora birambuye, urashobora guhuza sisitemu yuzuye yo gusesengura imikoreshereze yimodoka yihariye.Ibiciro bitandukanye byumuvuduko bigabanywa mumashami atandukanye yubucuruzi kugirango abafashe gutezimbere urujya n'uruza rwubucuruzi, gutunganya no guhindura imiyoboro ikoreshwa mike igihe icyo aricyo cyose, no kwagura imiyoboro yubucuruzi ikoreshwa cyane.
Imibare ihamye yimibare, namakuru yingenzi kuri SLA, nayo inkota ya Damocles kumutwe wa buri gikorwa no kubungabunga abakozi.Imibare ihamye yimibare ya OTN igomba gutandukanywa kubera uburinzi bwabo.Kurugero, niba inzira imwe ihagaritswe, umurongo mugari wose kuri IP ntuzagira ingaruka, niba uzashyirwa muri SLA;niba umurongo wa IP wagabanutseho kabiri, ariko ubucuruzi ntibuzagira ingaruka, niba buzashyirwa muri SLA;Niba umuyoboro umwe watsinzwe urimo muri SLA;kwiyongera gutinda inzira yo gukingira ntabwo bigira ingaruka kumurongo wumuyoboro, ariko bigira ingaruka mubucuruzi, bwaba burimo muri SLA, nibindi.Imyitozo rusange ni ukumenyesha uruhande rwubucuruzi ingaruka nka jitter no gutinza impinduka mbere yo kubaka.Nyuma SLA ibarwa hashingiwe ku mubare w'imiyoboro idakwiriye * umurongo w'umuyoboro umwe utari wo, ugabanijwe n'umubare rusange w'imiyoboro * igiteranyo cy'umuyoboro uhuye, hanyuma ukagwizwa Ukurikije igihe cy’ingaruka, agaciro kabonetse ikoreshwa nkigipimo cyo kubara SLA.
2 Gucunga umutungo
Umutungo wibikoresho bya OTN ukenera kandi gucunga ubuzima (kuhagera, kumurongo, gusiba, gukemura amakosa), ariko bitandukanye na seriveri, guhinduranya imiyoboro nibindi bikoresho, imiterere yibikoresho bya OTN iraruhije.Ibikoresho bya OTN birimo umubare munini wibibaho bikora, birakenewe rero gushushanya uburyo bwo gucunga umutungo wose mugihe cyo kuyobora.Ihuriro nyamukuru ryimicungire yumutungo wa IP muri data center rishingiye kuri seriveri no guhinduranya, kandi urwego rwibikoresho-shumba bizashyirwaho.Kuri iyi shingiro ya OTN, urwego-shebuja-imbata urwego ruzaba rufite imiyoborere, ariko hariho izindi nzego.Urwego rwubuyobozi rukorwa ahanini nibintu byurusobe-> subrack-> ikarita yubuyobozi-> module:
2.1.Umuyoboro wibikoresho nigikoresho kiboneka, kidafite ibintu bifatika.Ikoreshwa mubuyobozi hamwe ningingo yambere yumvikana mumurongo wa OTN, kandi ni iyurwego rwambere murwego rwo gucunga imiyoboro ya OTN.Icyumba cyibikoresho byumubiri gishobora kugira NE imwe cyangwa NE nyinshi.Urusobe rwibintu birimo subracks nyinshi, nka optique layer subracks, amashanyarazi yumurongo wamashanyarazi, hamwe na multiplexers yo hanze na demultiplexers nayo ifatwa nkibisubizo.Buri subrack irashobora guhuzwa murukurikirane kandi ni iya subrack murubuga rumwe rwibintu.Umubare.Byongeye kandi, urwego rwurusobe ntirufite numero SN numutungo, ugomba rero guhuzwa nurwego rwubuyobozi muriki kibazo, cyane cyane hamwe namakuru ari kurutonde rwubuguzi hamwe nuburyo bwo gucunga no gufata neza nyuma, kugirango birinde iperereza ryumutungo. ibyo bidahuye.Nyuma ya byose, urusobe rwibintu ni umutungo wukuri..
2.2.Igice kinini cyihariye cyibikoresho bya OTN ni chassis, ni ukuvuga subrack, iri murwego rwa kabiri rwurwego rwambere rwibanze.Nigice cya kabiri cyurwego, kandi urusobe rwibintu rufite byibura igikoresho kimwe cya subrack.Izi subrack zigabanijwe muburyo butandukanye bwabakora ibintu bitandukanye, hamwe nibikorwa bitandukanye, harimo ibikoresho bya elegitoroniki, ibikoresho bya fotone, ibisobanuro rusange, nibindi.Subrack ifite numero yihariye ya SN, ariko numero yayo ya SN ntishobora guhita iboneka binyuze murwego rwo gucunga imiyoboro, kandi irashobora kugenzurwa kurubuga gusa.Ntibisanzwe kwimuka no guhindura subrack nyuma yo kujya kumurongo.Ibibaho bitandukanye byinjijwe muri subrack.
2.3.Imbere murwego rwa kabiri subrack ya OTN, hari serivisi zihariye zo gushyira.Ibibanza bifite imibare kandi bikoreshwa mugushyiramo imbaho zitandukanye za serivise za optique.Izi mbaho nizo shingiro zo gushyigikira serivisi zurusobe rwa OTN, kandi buri kibaho gishobora kubaza SN binyuze muri sisitemu yo gucunga imiyoboro.Izi mbaho nigice cya gatatu murwego rwo gucunga umutungo wa OTN.Ubuyobozi butandukanye bwubucuruzi bufite ubunini butandukanye, butwara ahantu hatandukanye, kandi bufite imirimo itandukanye.Kubwibyo, mugihe inama ikeneye gushingwa kurwego rwa kabiri rwibice subrack, urubuga rwumutungo rugomba kwemerera ikibaho kimwe gukoresha ibibanza byinshi cyangwa igice kugirango bihuze numubare wibisobanuro kuri subrack.
2.4.Uburyo bwiza bwo gucunga umutungo.Module iterwa no gukoresha imbaho za serivisi.Inama zose zubucuruzi zigomba kwemerera module ya optique, ariko ntabwo ibikoresho byose bya OTN bigomba gucomeka muburyo bwa optique, bityo rero imbaho nazo zigomba kwemererwa Nta module ibaho.Buri cyiciro cya optique gifite numero ya SN, kandi module yinjijwe ku kibaho igomba guhuzwa nimero yicyambu kugirango ishakishe ahantu byoroshye.
Aya makuru yose arashobora gukusanywa binyuze mumajyaruguru yuburengerazuba bwurubuga ruyobora imiyoboro, kandi amakuru yukuri yumutungo arashobora gucungwa binyuze mugukusanya kumurongo no kugenzura kumurongo no guhuza.Mubyongeyeho, ibikoresho bya OTN birimo na attenuator optique, gusimbuka mugufi, nibindi. Ibikoresho bikoreshwa birashobora gucungwa neza nkibikoreshwa.
