Kusintha kwa Ma Node Owona: Kusintha kwa Ma Network Olumikizirana

Mu gawo la maukonde olumikizirana, chitukuko cha ma node optical ndi champhamvu kwambiri. Ma node awa amagwira ntchito yofunika kwambiri pakufalitsa deta, mawu ndi makanema, ndipo chitukuko chawo chakhudza kwambiri magwiridwe antchito ndi liwiro la machitidwe amakono olumikizirana. Mu blog iyi, tifufuza za kusintha kwa ma node optical ndi gawo lawo pakusintha kwa maukonde olumikizirana.

Lingaliro lama node owonekakuyambira masiku oyambirira a ukadaulo wa fiber optic. Poyamba, ma node awa anali zida zosavuta zomwe zimagwiritsidwa ntchito kusintha ma signal a kuwala kukhala ma signal amagetsi ndi mosemphanitsa. Amagwira ntchito ngati malo olumikizirana pakati pa ma network a fiber optic ndi zomangamanga zachikhalidwe zolumikizirana zochokera ku mkuwa. Komabe, pamene ukadaulo ukupita patsogolo, ntchito ya ma node a kuwala ikupitilira kukula, ndipo akhala gawo lofunikira kwambiri pakukhazikitsa ma network apamwamba olumikizirana.

Chimodzi mwa zinthu zofunika kwambiri pa ukadaulo wa ma node a optical ndi kuphatikiza magwiridwe antchito a wavelength division multiplexing (WDM). WDM imalola kuti mitsinje yambiri ya deta ifalitsidwe nthawi imodzi pa ulusi umodzi pogwiritsa ntchito ma wavelength osiyanasiyana a kuwala. Ukadaulowu umawonjezera kwambiri mphamvu ndi magwiridwe antchito a ma network a optical, zomwe zimathandiza kutumiza deta yambiri pa liwiro lalikulu.

Chinthu china chachikulu chomwe chikuchitika muukadaulo wa ma node a kuwala ndi kuphatikiza ma amplifiers a kuwala. Ma amplifiers awa amagwiritsidwa ntchito kuwonjezera mphamvu ya ma siginecha a kuwala, zomwe zimathandiza kuti azitha kutumizidwa patali popanda kugwiritsa ntchito zida zokwera mtengo komanso zovuta zokonzanso ma siginecha. Kuphatikizidwa kwa ma amplifiers a kuwala mu ma node a kuwala kwasintha masewerawa pama netiweki olumikizirana akutali, zomwe zathandiza kuti pakhale kulumikizana kwamphamvu komanso kothamanga kwambiri patali.

Kuphatikiza apo, kupangidwa kwa ma node optical kwapangitsa kuti pakhale ma multiplexers owonjezera ma optical (ROADM). Zipangizozi zimathandiza ogwiritsa ntchito ma netiweki kuti asinthe njira zowunikira patali mkati mwa ma netiweki awo, zomwe zimathandiza kuti bandwidth igwiritsidwe ntchito mwachangu komanso kusinthasintha kwa netiweki kukhale kofunikira kwambiri. Ma node optical ogwiritsidwa ntchito ndi ROADM amagwira ntchito yofunika kwambiri pakukhazikitsa ma netiweki olumikizirana omwe amatha kukwanitsa zosowa zomwe zikukula za bandwidth ndi kulumikizana.

Kupita patsogolo kwaposachedwa kwa ukadaulo wa ma node a optical kumaphatikizapo kuphatikiza kwa luso lanzeru la ma network (SDN). Izi zimathandiza kuwongolera ndi kuyang'anira ma network a optical pakati, zomwe zimathandiza kusintha kwa zinthu za ma network komanso kukonza bwino magalimoto. Ma node optical omwe amagwiritsidwa ntchito ndi SDN amatsegula njira yopangira ma network olumikizirana omwe amadzipangira okha komanso odzichiritsa okha, omwe amatha kusintha malinga ndi kusintha kwa ma network nthawi yeniyeni.

Mwachidule, chitukuko chama node owonekayakhala ndi gawo lofunika kwambiri pakusintha kwa maukonde olumikizirana. Kuchokera ku zida zosavuta kusintha ma signal mpaka kuzinthu zovuta za netiweki, ma node optical amachita gawo lofunikira pakulola kukhazikitsidwa kwa maukonde olumikizirana amphamvu kwambiri komanso othamanga kwambiri. Pamene ukadaulo ukupitilira kupita patsogolo, titha kuyembekezera zatsopano zina muukadaulo wa ma node optical, zomwe zikuyendetsa kusinthika kwa maukonde olumikizirana ndikukonza tsogolo la kulumikizana.
