Mu rwego rw'imiyoboro y'itumanaho, iterambere ry'udutsiko tw'amajwi ni impinduka zikomeye. Utu dutsiko tugira uruhare runini mu kohereza amakuru, amajwi n'amashusho, kandi iterambere ryatwo ryagize ingaruka zikomeye ku mikorere n'umuvuduko wa sisitemu zigezweho z'itumanaho. Muri iyi blog, tuzasuzuma iterambere ry'udutsiko tw'amajwi n'uruhare rwatwo mu mpinduramatwara y'itumanaho.
Igitekerezo cyautudomo tw'amasobyatangiye mu ntangiriro z'ikoranabuhanga rya fiber optique. Mbere na mbere, izi node zari ibikoresho byoroshye byakoreshwaga mu guhindura ibimenyetso by'amashanyarazi mo ibimenyetso by'amashanyarazi, naho ubundi. Bikora nk'ahantu hahuza imiyoboro ya fiber optique n'ibikorwa remezo by'itumanaho bisanzwe bishingiye ku muringa. Ariko, uko ikoranabuhanga rigenda ritera imbere, uruhare rw'izi node z'amashanyarazi rukomeza kwaguka, kandi byabaye igice cy'ingenzi mu gushyiraho imiyoboro y'itumanaho igezweho.
Imwe mu ntambwe z'ingenzi zatewe mu ikoranabuhanga rya optique node ni uguhuza imikorere ya wavelength division multiplexing (WDM). WDM yemerera imiyoboro myinshi y'amakuru koherezwa icyarimwe kuri fibre imwe hakoreshejwe uburebure butandukanye bw'urumuri. Iri koranabuhanga ryongera cyane ubushobozi n'imikorere myiza y'imiyoboro ya optique, bigatuma amakuru menshi yoherezwa ku muvuduko mwinshi.
Irindi terambere rikomeye mu ikoranabuhanga rya optique node ni uguhuza optique amplifiers. Izi amplifiers zikoreshwa mu kongera imbaraga z'ibimenyetso by'urumuri, bigatuma byoherezwa mu ntera nini nta gikenewe cy'ibikoresho bihenze kandi bigoye byo kuvugurura ibimenyetso. Gushyira optique amplifiers mu bice by'urumuri byahinduye imikorere y'imiyoboro y'itumanaho igera kure, bituma habaho ishyirwa ry'itumanaho rifite ubushobozi bwo hejuru kandi ryihuse mu ntera ndende.
Byongeye kandi, iterambere ry’udutsiko tw’amajwi ryatumye habaho ishyirwaho rya multiplexers zishobora kongeramo ikoranabuhanga (ROADM). Ibi bikoresho byemerera abakora imiyoboro y’amajwi kongeramo ikoranabuhanga mu buryo bworoshye mu miyoboro yabo, bigatuma habaho uburyo bwo gushyiraho bandwidth buhindagurika kandi bukongera ubwisanzure bw’imiyoboro y’amajwi. Udutsiko tw’amajwi dukoresha ROADM tugira uruhare runini mu gushyiraho imiyoboro y’itumanaho ikora neza kandi ishobora guhaza ibyifuzo byiyongera by’uburyo bwo gukoresha bandwidth no guhuza.
Iterambere riherutse mu ikoranabuhanga rya optique node rikubiyemo guhuza ubushobozi bwa software defined networking (SDN). Ibi byemerera kugenzura no gucunga imiyoboro ya optique, bigatuma habaho imiterere ihindagurika y’umutungo wa optique hamwe n’imikorere myiza y’ikoranabuhanga. Imiyoboro ya optique ikoresha SDN itegura iterambere ry’imiyoboro y’itumanaho yiyubaka kandi ikiza ubwayo, ishobora kumenyera imiterere y’imiyoboro mu gihe nyacyo.
Muri make, iterambere ryautudomo tw'amasoyagize uruhare runini mu ihinduka ry’imiyoboro y’itumanaho. Kuva ku bikoresho byoroshye byo guhindura ibimenyetso kugeza ku bice by’ikoranabuhanga bitoroshye, utudomo tw’urumuri tugira uruhare runini mu gutuma imiyoboro y’itumanaho ifite ubushobozi bwo hejuru kandi yihuta ikwirakwizwa. Uko ikoranabuhanga rikomeza gutera imbere, dushobora kwitega udushya twinshi mu ikoranabuhanga ry’utudomo tw’urumuri, tugatera imbere iterambere ry’imiyoboro y’itumanaho no gushyiraho ahazaza ho guhuza.
