Txhawm rau kom muaj peev xwm thauj tau cov kev sib txuas hauv video soj ntsuam lub network, qhov hloov pauv yuav tsum nkag mus rau ntau lub koob yees duab, thiab qhov loj dua cov ntaub ntawv ntim ntawm qhov hloov. Cov kev hloov yuav tsum muaj lub peev xwm ruaj khov heev los hloov cov ntaub ntawv kom xa cov khoom loj thiab tsis tu ncua Video ntaub ntawv. Yog li, yuav tsum hloov ethernet xaiv 100M lossis 1000M?

Cov ntaub ntawv xa mus rau ib chav tsev thaum lub sij hawm cov ntaub ntawv kis tau tus mob hu ua code kwj, yog hais tias tus nqi ntawm cov ntaub ntawv xa mus los ntawm lub koob yees duab nyob rau hauv lub hloov dua siab tshiab lub peev xwm ntawm ib tug tej chaw nres nkoj, nws kuj yuav ua rau qhov chaw nres nkoj no pov tseg ib tug ntau ntawm cov ntaub ntawv thiab ua rau muaj teeb meem.

Piv txwv li, 100M hloov mus rau cov ntaub ntawv ntim ntau tshaj 100M, uas yuav ua rau cov pob ntawv poob ntau, ua rau lub vijtsam khov. Yog li, pes tsawg lub koob yees duab koj yuav tsum xaiv lub gigabit hloov?

Muaj tus qauv, nyob ntawm tus nqi ntawm cov ntaub ntawv xa los ntawm lub koob yees duab qhov chaw nres nkoj uplink: yog tias cov ntaub ntawv xa mus los ntawm qhov chaw nres nkoj uplink ntau dua 70M, xaiv qhov chaw nres nkoj gigabit, uas yog, xaiv lub gigabit hloov lossis gigabit uplink hloov. .

Muaj kev suav ceev thiab xaiv txoj kev: tus nqi bandwidth = (sub kwj + lub ntsiab kwj) * tus naj npawb ntawm cov channel * 1.2:

① Bandwidth tus nqi> 70M, siv gigabit;

②Bandwidth tus nqi

Nqe Lus Nug 1: Cov txheej txheem kwj dej yog qhov tseeb heev, tab sis vim li cas thiaj yuav tsum tau muab faib ua 1.2?

Vim hais tias raws li lub hauv paus ntsiab lus ntawm kev sib txuas lus network, lub encapsulation ntawm cov ntaub ntawv packets kuj ua raws li TCP / IP raws tu qauv, thiab cov ntaub ntawv ib feem yuav tsum tau cim nrog lub header teb ntawm txhua tus txheej txheem txheej txheem yuav kis tau yooj yim, yog li lub header tseem yuav nyob ib ib feem ntawm cov nyiaj siv ua haujlwm.
Lub 4M ntsis tus nqi thiab 2M ntsis tus nqi ntawm lub koob yees duab peb feem ntau tham txog yog hais txog qhov loj ntawm cov ntaub ntawv ib feem. Raws li cov ntaub ntawv kev sib txuas lus piv, lub taub hau nyiaj siv ua haujlwm yog kwv yees li 20%, yog li cov qauv yuav tsum tau muab faib ua 1.2.

Nqe Lus Nug 2: Vim li cas 70M tsis yog 100M?

Feem ntau xav txog kev tawg tsheb. Cov ntaub ntawv video kwj yog tsim los ntawm ntau tus ncej. Qhov seemingly du cov ntaub ntawv kwj yeej muaj ntau instantaneous bursts ntawm cov ntaub ntawv. Qhov teeb meem no yuav tsum tau hloov mus rau tsis thiab kho qhov hloov pauv ntawm cov ntaub ntawv.
Cov kev hloov pauv-rau-kem-kho-rau pem hauv ntej cov ntaub ntawv no, yog li nws raug pom zoo kom muaj qee qhov tshwj xeeb. Thaum tsim lub network hloov, tuaj yeem muaj 30% -40% kev tshwj tseg. Rau qhov chaw nres nkoj 100M, nws raug pom zoo tias kev xa mus tsis pub dhau 70M.
