Hauv kev sib txuas lus sib txuas lus, kev txhim kho kho qhov muag yog hloov kho. Cov nodes ua si ib lub luag haujlwm tseem ceeb hauv kev xa cov ntaub ntawv, lub suab thiab lawv txoj kev txhim kho tau yooj yim heev rau kev ua tau zoo thiab nrawm ntawm cov tshuab sib txuas lus niaj hnub no. Hauv cov blog no, peb yuav tshawb txog kev hloov kho ntawm cov tshuaj kho qhov muag thiab lawv lub luag haujlwm hauv kev sib txuas lus network hloov.
Lub tswvyim ntawmNodes kho qhov muagCov hnub rov qab mus rau hnub thaum ntxov ntawm fiber ntau thev naus laus zis. Thaum pib, cov nodes tau muab khoom siv yooj yim siv los hloov cov cim kho qhov muag rau hauv cov cim hluav taws xob thiab hloov kho cov hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho cov hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho cov hluav taws xob thiab hloov kho hluav taws xob thiab hloov kho hluav taws xob. Lawv ua haujlwm raws li kev sib txuas lus ntawm fiber ntau optic tes hauj lwm thiab cov tooj liab ib txwm muaj kev sib txuas lus. Txawm li cas los xij, raws li thev naus laus zis kev nce qib, lub luag haujlwm ntawm cov tshuaj kho qhov muag tseem nthuav dav, thiab lawv tau dhau los ua kev sib txuas lus tsis tseem ceeb hauv kev xa tawm cov tuam txhab sib txuas lus siab.
Ib qho kev nce qib tseem ceeb hauv kev siv tshuab ntawm lub tshuab thev naus laus zis yog wavelength ntawm wavelength divisen colational cultipxing (WDM) ua haujlwm. WDM tso cai ntau cov ntaub ntawv ntws los kis tau ib txhij dhau ib fiber ntau siv wavelengths ntawm lub teeb. Cov thev naus laus zis ntau tshaj qhov muaj peev xwm thiab kev ua tau zoo ntawm kho qhov muag tau, ua rau kev sib kis tau ntawm cov ntaub ntawv loj ntawm cov ntaub ntawv ntawm kev kub ceev.
Lwm txoj kev loj hlob loj hauv kev kho mob ntawm lub tshuab yog kev sib koom ua ke ntawm kev siv kho kom zoo nkauj. Cov khoom lag luam zoo li cas los ua kom muaj zog ntawm cov cim kho kho qhov muag uas tsis tas yuav muaj cov khoom siv txuas ntxiv. Qhov muaj kev sib txuam ntawm kev kho qhov muag tau hloov kho cov nodes tau hloov pauv cov kev ua si ntev ntev, kev sib txuas nrawm nrawm dhau mus deb.
Tsis tas li ntawd, kev txhim kho kho qhov muag tau coj mus rau kev txhim kho ntawm Reconfigurable kho qhov muag ntxiv-See multiplexers (railms). Cov cuab yeej siv no tso cai rau cov koom tes ua haujlwm rau kev rov qab kho kho qhov muag ntawm lawv cov tes haujlwm hauv lawv cov tes haujlwm, ua kom muaj kev faib tawm tshiab ntawm bandwidth thiab nce network yooj ywm. Roadm-enabled optical nodes ua lub luag haujlwm tseem ceeb hauv kev xa tawm ntawm agile, hloov kev sib txuas lus network muaj peev xwm ntawm kev sib tham txog kev xav tau rau bandwidth thiab kev sib txuas.
Tsis ntev los no kev hloov kho hauv Optical Node Technology emodody Kev koom ua ke ntawm cov software txawj ntse - txhais tau tias kev ua tau zoo (SDN) lub peev xwm. Qhov no tso cai rau kev tswj hwm kev tswj hwm thiab kev tswj hwm ntawm kho qhov muag tes hauj lwm, ua rau cov kev teeb tsa kev txhim kho ntawm cov network thiab cov tsheb ua haujlwm ua tau zoo. SDN-enabled optical nodes pave txoj kev rau txoj kev loj hlob ntawm tus kheej txoj kev sib txuas lus, muaj peev xwm hloov kho cov network ntawm lub sijhawm.
Hauv cov ntsiab lus, kev txhim kho ntawmNodes kho qhov muagtau ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm kev sib txuas lus. Los ntawm cov teeb liab yooj yim hloov dua siab hloov cov cuab yeej ua ke rau cov khoom siv sib xyaw ua ke, kho qhov muag ua si lub peev xwm tseem ceeb hauv kev xa cov peev txheej, kev sib txuas lus nrawm nrawm. Raws li thev naus laus zis txuas ntxiv mus ua ntej, peb tuaj yeem tos ntsoov yuav ua kom muaj kev hloov kho tshiab ntxiv, tsav tsheb txuas ntxiv ntawm kev sib txuas lus network thiab shaping yav tom ntej ntawm kev sib txuas.
