Xws li virtualization, Software txhais Networking (SDN) technology yog ib yam tseem ceeb heev rau huab xam cov me nyuam ntxiv. Tshaj dhau ob peb lub hlis, nws txoj kev loj hlob hnyav tau ua rau txoj kev ua tsis tseem ceeb nyob rau hauv cov ntsiab lus ntawm bandwidth. Ib qho tseem ceeb tshaj plaws uas peb feem coob yuav tsis nco txog huab yog tias nws tsis yog tag nrho cov. Nyob rau ntawm ib qho lossis lwm qhov chaw nyob hauv lub ntiaj teb, nws yuav tsum yog ib qhov chaw khaws ntaub ntawv lossis lub cev nqaij daim tawv uas ua haujlwm zoo ib yam li pob txha ntawm huab huab.
Qhov no txhais li cas rau cov neeg muag khoom huab?
Kev tswj hwm nws txoj kev xav nrog kev astounding huab loj loj, lawv yuav tsum tsim kom muaj ntau cov chaw zov me nyuam cov ntaub ntawv, muab lawv thooj av los txo qis latency mus rau qhov siab tshaj plaws rau cov neeg hauv ntiaj teb no. Ntau yam ntawm lawv ua kom siv cov huab cua kub rau lawv tus kheej rau kev tswj cov chaw no thiab txuas lawv ua ke.
Lawm, nws yuav ua rau cov neeg xav tau ntawm lub network. Yog li, tam sim no networking tshuab yog ceev nrooj ua ib qho ntawm cov khoom loj tshaj hauv huab teb. Qhov teeb meem yog tias qhov kev sib txuas ntawm cov cuab yeej kho vaj tse tsis tau tawm los tswj lawv txoj kev nrog huab txawm tias xam cov khoom kho. Hauv cov lus yooj yim, nws yuav tsis yog los ntawm qhov yooj yim xa los yog scalable.
SDN Cov Kauj Ruam Hauv
Cov kev sib tw nyob rau hauv pem hauv ntej ntawm cov neeg teb xov tooj network yog qhov loj heev li lawv yuav tsum muaj nyob rau hauv kev xav nrog kev thov los ntawm cov neeg muas zaub. Cov teeb meem tseem ceeb yog ua kom tau raws li qhov xav tau ntxiv rau bandwidth thiab cov xaib tshiab ntawm cov kev pab tshiab rau cov neeg siv khoom. Qhov no implies tias cov tswv lag luam tsis cia li xav tau ib lub lag luam scalable, tab sis kuj yog ib qho ci ntsa iab. Qhov no yog qhov twg SDN cov kauj ruam hauv.
Qhov uas yuav tsum muaj rau cov programable programmable, uas tuaj yeem tau teev tseg rau ntawm qhov kev hloov ntawm lub tswv yim tseem ceeb tom qab kev loj hlob ntawm tus kheej cov khoom siv thiab huab apps - ob ntawm qhov loj tshaj plaws uas ua ke yog tsav tsheb hloov kev hloov hauv kev lag luam ntawm kev lag luam thiab IT. SDN muab sij hawm los txhawm rau kom xa cov ntaub ntawv nrog rau cov nqi txiav tawm.
Yeej, ib qho SDN yog rau kev sib txuas lus sib tham txog qhov huab yog rau ib qho kev coj mus muag ua lag luam. Cov kev siv uas, SDN yog tswj, muaj kev sib txawv los ntawm kev kho vajtse - qhov kev tso cai ntxiv no thiab sau tag nrho ntawm kev kho software thiab kho vajtse. Nws tseem muab qhov yooj thiab qhov scalability qib uas yuav tsum tau ntxiv rau huab cua evolution.
Tsis tas li ntawd, yuav tsum muaj cov neeg txuas mus rau qhov tsis muaj kev txwv thiab kev siv tshuab automation, SDN qhia tau hais tias muaj lwm txoj hau kev rau cov kev pabcuam siab rau cov neeg muag khoom nrog rau cov neeg muag khoom. Nrog rau txoj haujlwm sib koom tes, SDNs muaj ntau qhov zoo sib xws li huab ua ntu tawm ntawm lub tuam txhab. Kev ua kom yooj yooj yim thiab muaj peev xwm yuav tso cai siv ntau dua kev siv kev sib txuas lus, thaum tus nqi khiav lag luam yuav ua rau muaj kev lag luam thiab txuag tseem ceeb ntawm tus neeg mob qhov.
Xav txog txhua qhov system - tag nrho yog qhov tseem ceeb raws li nws cov khoom tivthaiv - huab tsis muaj qhov tshwj rau txoj cai no.
Thaum nws muaj tseeb tias huab huab yog ib qho tseem ceeb tshaj plaws thiab cov cuab yeej ua lag luam rau txhua lub lag luam, tib lub sij hawm, nws cov peev xwm ua tiav tsis tuaj yeem pom tseeb yog loaded nrog cov khoom vaj khoom tsev pom zoo. Qhov no xyov yog vim li cas SDN muaj xws li qhov tseem ceeb thiab ze kev twb kev txuas nrog huab.
Tsis muaj SDN, huab xam cia li tsis tuaj yeem ua kom nws cov evolution, thiab qhov sib txuas ntawm huab xam thiab software txhais network yog qhov muaj zog heev.
