Cov keyboards ib txwm tsim los ntawm cov choj thiab koom nrog txheej thib ob ntawm OSI, cov khoom siv txuas ntaub ntawv. Nws chaw nyob raws li MAC chaw nyob, xaiv txoj kev hla lub rooj chaw nres tsheb, thiab kev tsim thiab kev saib xyuas ntawm lub rooj chaw nres tsheb raug ua los ntawm CISCO Cisco switches. Lub router koom nrog txheej thib peb ntawm OSI, uas yog, lub cuab yeej txheej network. Nws chaw nyob raws li IP chaw nyob thiab raug tsim los ntawm cov txheej txheem routing table routing. Qhov zoo tshaj plaws ntawm peb txheej 10 Gigabit switch yog ceev. Vim tias lub switch tsuas yog xav tau txheeb xyuas MAC chaw nyob hauv lub thav duab, nws ncaj qha tsim thiab xaiv cov algorithm chaw nres nkoj xa mus raws li MAC chaw nyob. Lub algorithm yooj yim thiab yooj yim rau kev siv los ntawm ASIC, yog li qhov ceev xa mus yog siab heev. Tab sis lub tshuab ua haujlwm ntawm lub switch kuj coj qee qhov teeb meem.
1. Lub voj voog: Raws li Huanet qhov chaw nyob hloov chaw kawm thiab chaw nres tsheb rooj tsim algorithm, loops tsis pub ntawm cov switches. Thaum muaj ib lub voj voog, lub spanning tree algorithm yuav tsum pib los thaiv qhov chaw nres nkoj uas tsim lub voj voog. Lub router's routing protocol tsis muaj qhov teeb meem no. Muaj peev xwm muaj ntau txoj kev ntawm cov routers kom sib npaug qhov load thiab txhim kho kev ntseeg tau.
2. Kev sib sau ua ke ntawm cov khoom thauj:Tsuas muaj ib txoj channel ntawm Huanet switches xwb, yog li cov ntaub ntawv raug tsom mus rau ib qho kev sib txuas lus, thiab kev faib tawm dynamic tsis tuaj yeem ua kom sib npaug ntawm qhov load. Lub router's routing protocol algorithm tuaj yeem zam qhov no. OSPF routing protocol algorithm tsis yog tsuas yog tsim ntau txoj kev, tab sis kuj xaiv cov kev zoo tshaj plaws sib txawv rau cov ntawv thov network sib txawv.
3. Kev tswj hwm kev tshaj tawm:Cov Huanet switches tsuas yog txo tau qhov teeb meem ntawm qhov chaw sib cav sib ceg xwb, tab sis tsis txo tau qhov chaw tshaj tawm. Tag nrho lub network switched yog ib qho chaw tshaj tawm loj, thiab cov lus tshaj tawm tau tawg thoob plaws hauv lub network switched. Lub router tuaj yeem cais qhov chaw tshaj tawm, thiab cov pob ntawv tshaj tawm tsis tuaj yeem txuas ntxiv tshaj tawm los ntawm lub router.
