Nyuma y'uko umuyoboro wa DCI utangije ikoranabuhanga rya OTN, bingana no kongeramo akazi kose katari kariho mbere mu bijyanye n'imikorere. Umuyoboro gakondo w'amakuru ni umuyoboro wa IP, ugizwe n'ikoranabuhanga rya logique network. OTN muri DCI ni ikoranabuhanga rikoresha imiterere y'umubiri, kandi uburyo bwo gukorana n'urwego rwa IP mu buryo bwiza kandi bworoshye ni inzira ndende yo gukora.
Muri iki gihe, intego y'imikorere ishingiye kuri OTN ni imwe n'iya buri sisitemu nto y'ikigo cy'amakuru. Byose bigamije kongera umusaruro w'umutungo ushorwa mu bikorwa remezo bihendutse no gutanga ubufasha bwiza ku serivisi zo mu rwego rwo hejuru. Kunoza uburyo bw'ibanze buhamye, koroshya imikorere n'ibikorwa byo kubungabunga, gufasha mu igabanywa ry'umutungo mu buryo bushyize mu gaciro, gutuma umutungo ushorwa ugira uruhare runini, no kugena umutungo utashowe mu buryo bukwiye.
Imikorere ya OTN ikubiyemo ahanini ibice byinshi: gucunga amakuru y'imikorere, gucunga umutungo, gucunga igenamiterere, gucunga inzogera, gucunga imikorere, no gucunga DCN.
1 Amakuru y'imikorere
Kora imibare ku makuru y'ikosa, utandukanye amakosa y'abantu, amakosa ya mudasobwa, amakosa ya porogaramu, n'amakosa y'abandi, kandi ukore isesengura ry'ibarurishamibare ku bwoko bw'amakosa akomeye, ushyireho gahunda zo gutunganya zigamije, kandi utange inzira yo gutunganya amakosa mu buryo bwikora nyuma yo gushingira ku mahame ngenderwaho mu gihe kizaza. Dukurikije isesengura ry'amakuru y'ikosa, sisitemu yatunganyijwe neza kugira ngo ikore akazi kazakorwa mu gihe kizaza nko gushushanya inyubako no guhitamo ibikoresho, kugira ngo bigabanye ikiguzi cy'imirimo yo nyuma yo gukora no kubungabunga. Kuri OTN, kora imibare y'amakosa uhereye kuri amplifiers optique, boards, modules, multiplexers, cross-device jumpers, trunk fibres, DCN networks, nibindi, gira uruhare mu bipimo by'uruganda, third-party dimensions, nibindi, kandi ukore isesengura ry'amakuru menshi kugira ngo ubone amakuru nyayo. Ishobora kugaragaza neza uko umuyoboro umeze.
Kora imibare ku makuru y’impinduka, utandukanye ingorane n’ingaruka z’impinduka, ushyire abakozi mu byiciro, kandi ugire impinduka hakurikijwe inzira yo gusesengura ibisabwa, gahunda y’impinduka, gushyiraho idirishya, kumenyesha abakoresha, ishyirwa mu bikorwa ry’ibikorwa, n’isuzuma ry’incamake, hanyuma ushobore gukora impinduka zitandukanye. Igabanyijemo amadirishya, ndetse ikanashyirwa mu bikorwa ku manywa, kugira ngo igenamiterere ry’abakozi bahindura rirusheho kuba ryiza, rigabanye umuvuduko w’akazi n’ubuzima, kandi rinongere ibyishimo by’abahanga mu by’imikorere. Ishobora kandi guhuza amakuru ya nyuma y’ibarurishamibare no kuyakoresha nk'icyitegererezo cy’imikorere myiza y’abakozi n’ubushobozi bw’akazi. Muri icyo gihe, kandi ituma impinduka zisanzwe zitera imbere mu cyerekezo cyo gushyiraho amabwiriza no gukora ibintu mu buryo bwikora, bigabanyije amafaranga atandukanye akoreshwa.
Gukusanya imibare ku ikwirakwizwa rya serivisi za OTN kugira ngo bigufashe kumenya ikoreshwa rya interineti no kugenzura ikwirakwizwa ry’imiyoboro yose y’itumanaho n’ikwirakwizwa rya serivisi nyuma y’ubwiyongere bw’ubwinshi bw’ubucuruzi. Iyo ubikoze nabi, ushobora kumenya serivisi y’itumanaho umuyoboro umwe ukoresha, nko mu muyoboro wo hanze, intranet, umuyoboro wa HPC, umuyoboro wa serivisi z’ibicu, nibindi. Iyo ubisobanuye neza, ushobora guhuza sisitemu yuzuye kugira ngo usesengure ikoreshwa ry’urujya n’uruza rw’ubucuruzi runaka. Ikiguzi cy’umurongo w’itumanaho gitandukanye kigabanywa ku mashami atandukanye y’ubucuruzi kugira ngo bibafashe kunoza urujya n’uruza rw’ubucuruzi, kongera gukoresha no guhindura imiyoboro ikoreshwa mu buryo budahagije igihe icyo ari cyo cyose, no kwagura imiyoboro ikoreshwa mu bucuruzi cyane.
Amakuru ajyanye n'imibanire, ari na yo makuru y'ingenzi akoreshwa kuri SLA, ni nayo nkota ya Damocles ku mutwe wa buri mukozi ushinzwe ibikorwa n'ubugenzuzi. Imibare y'amakuru ajyanye n'imiturire ya OTN igomba gutandukanywa bitewe n'uburyo ibungwabungwa bwayo. Urugero, niba inzira imwe ihagaze, umuyoboro wose w'itumanaho ku rwego rwa IP ntuzahinduka, niba uzashyirwa muri SLA; niba umuyoboro wa IP wagabanijwemo kabiri, ariko ubucuruzi ntibuzahinduka, niba uzashyirwa muri SLA; niba hari ikibazo cy'umuyoboro umwe muri SLA; kwiyongera kw'itinda ry'inzira y'uburinzi ntibigira ingaruka ku muyoboro w'itumanaho, ahubwo bigira ingaruka ku bucuruzi, niba uzashyirwa muri SLA, n'ibindi. Uburyo rusange ni ukumenyesha uruhande rw'ubucuruzi ibyago nko guhinduka kw'ihindagurika ry'ihindagurika mbere yo kubaka. SLA ya nyuma ibarwa hashingiwe ku mubare w'imiyoboro ifite amakosa * umuyoboro w'umuyoboro umwe ufite amakosa, ugabanyijwe n'umubare w'imiyoboro yose * igiteranyo cy'umuyoboro w'itumanaho ujyanye, hanyuma ugakuba na Hashingiwe ku gihe cy'ingaruka, agaciro kabonetse gakoreshwa nk'igipimo ngenderwaho cyo kubara cya SLA.
2 Imicungire y'Umutungo
Imitungo y'ibikoresho bya OTN nayo ikenera imicungire y'ubuzima (kugera, kuri interineti, gusiba, gucunga amakosa), ariko bitandukanye na seriveri, swichi za network n'ibindi bikoresho, imiterere y'ibikoresho bya OTN iragoye cyane. Ibikoresho bya OTN bikubiyemo umubare munini w'amabaruwa akora, bityo ni ngombwa gushushanya uburyo bwo gucunga umutungo wose mu gihe cyo gucunga. Urubuga rw'ingenzi rw'imicungire y'umutungo wa IP mu kigo cy'amakuru rushingiye kuri seriveri na swichi, kandi urwego rw'igikoresho cya master-slave ruzashyirwaho. Kuri ubu hashingiwe kuri OTN, urwego rwa master-slave ruzaba rukubiyemo imicungire y'urwego, ariko hari urwego rwinshi. Urwego rw'imicungire rukorwa ahanini na module ya network element->subrack->board card->:
2.1. Ikintu cy'umuyoboro ni igikoresho kigaragara, kidafite ibintu bifatika. Gikoreshwa mu gucunga no mu ngingo ya mbere y'ubwenge mu muyoboro wa OTN, kandi ni icy'urwego rwa mbere mu gucunga umuyoboro wa OTN. Icyumba cy'ibikoresho bifatika gishobora kugira NE imwe cyangwa NE nyinshi. Ikintu cy'umuyoboro kirimo subrack nyinshi, nka subrack za optique layer, subrack za electrical layer, na multiplexers zo hanze na demultiplexers nazo zifatwa nk'subrack. Buri subrack ishobora guhuzwa mu buryo bukurikiranye kandi ikaba icy'subrack mu rubuga rumwe rw'ikintu cy'umuyoboro. Gutanga nimero. Byongeye kandi, ikintu cy'umuyoboro nta nimero ya SN ifite umutungo, bityo igomba guhuzwa n'urubuga rw'ubuyobozi muri uru rwego, cyane cyane n'amakuru ari ku rutonde rw'ibyaguzwe n'urubuga rwo gucunga ibikorwa no kubungabunga nyuma, kugira ngo hirindwe iperereza ku mutungo ritajyanye. N'ubundi kandi, ikintu cy'umuyoboro ni umutungo ugaragara.
2.2. Igice kinini cyihariye cy’ibikoresho bya OTN ni chassis, ni ukuvuga subrack, iherereye ku rwego rwa kabiri rw’igice cya mbere cy’umuyoboro w’amashanyarazi. Ni igice cyo ku rwego rwa kabiri, kandi igice cy’umuyoboro gifite nibura igikoresho kimwe cya subrack. Izi subrack zigabanyijemo moderi zitandukanye z’inganda zitandukanye, zifite imikorere itandukanye, harimo subrack z’ikoranabuhanga, subrack za photon, subrack rusange, n'ibindi. Subrack ifite inomero ya SN yihariye, ariko inomero yayo ya SN ntishobora kuboneka mu buryo bwikora binyuze kuri platforme yo gucunga umuyoboro w’amashanyarazi, kandi ishobora kugenzurwa gusa aho iherereye. Ni gake cyane kwimura no guhindura subrack nyuma yo kujya kuri interineti. Hari imbaho zitandukanye zishyirwa muri subrack.
2.3. Mu gice cya kabiri cya OTN, hari imyanya yihariye yo gushyiramo serivisi. Imirongo ifite imibare kandi ikoreshwa mu gushyiramo imiyoboro itandukanye ya serivisi z'imiyoboro ya optique. Iyi miyoboro ni yo shingiro ryo gushyigikira serivisi za OTN, kandi buri kibaho gishobora kubaza SN yacyo binyuze muri sisitemu yo gucunga umuyoboro. Iyi miyoboro ni ibice byo ku rwego rwa gatatu mu gucunga umutungo wa OTN. Imirongo itandukanye y'ubucuruzi ifite ingano zitandukanye, ifata imyanya itandukanye, kandi ifite imirimo itandukanye. Kubwibyo, iyo ikibaho gikeneye gushyirwa mu gice cya kabiri cy'umuyoboro, urubuga rw'umutungo rugomba kwemerera ikibaho kimwe gukoresha imyanya myinshi cyangwa igice kugira ngo ihuze n'imibare y'umuyoboro kuri icyo gice.
2.4. Gucunga umutungo wa module y'urumuri. Module zishingira ku ikoreshwa ry'amabati ya serivisi. Amabati yose y'ubucuruzi agomba kwemerera module y'urumuri gutunga, ariko si amabati yose y'ibikoresho bya OTN agomba gushyirwa muri module z'urumuri, bityo amabati agomba no kwemererwa. Nta module ihari. Buri module y'urumuri ifite inomero ya SN, kandi module yinjijwe kuri bord igomba guhuzwa na nomero y'aho bord iherereye kugira ngo byoroshye gushakisha aho iherereye.
Aya makuru yose ashobora gukusanywa binyuze mu nzira yo mu majyaruguru y’urubuga rwo gucunga umuyoboro w’itumanaho, kandi ukuri kw’amakuru y’umutungo gushobora gucungwa binyuze mu gukusanya kuri interineti no kugenzura no guhuza ukoresheje interineti. Byongeye kandi, ibikoresho bya OTN bikubiyemo ibikoresho bigabanya urumuri, ama-jumper magufi, nibindi. Ibi bikoresho bishobora gucungwa mu buryo butaziguye nk'ibikoresho bishobora gucungwa mu buryo butaziguye.
