Domin samun damar loda tsarin tsarin sa ido na bidiyo mai rikitarwa, mai sauyawa yana buƙatar samun damar samun ƙarin kyamarori, kuma mafi girman ƙarar bayanai na sauyawa. Dole ne maɓalli ya kasance yana da ingantaccen ƙarfin jujjuya bayanai don isar da adadi mai yawa da ci gaba da bayanan Bidiyo. Don haka, ya kamata maɓalli na ethernet ya zaɓi 100M ko 1000M?

Bayanan da ake yadawa a kowane lokaci a lokacin watsa bayanai ana kiran su code stream, idan adadin bayanan da kyamarar ke turawa a ƙarƙashin mashigin ya zarce karfin tura wani tashar tashar jiragen ruwa, hakanan zai sa wannan tashar ta zubar da adadi mai yawa na bayanai. haifar da matsala.

Akwai ma'auni, dangane da adadin bayanan da tashar tashar sama ta kyamara ke turawa: idan adadin bayanan da tashar tashar ta sama ta kai sama da 70M, zaɓi tashar gigabit, wato, zaɓi gigabit switch ko gigabit uplink switch. .

Akwai lissafin sauri da hanyar zaɓi: ƙimar bandwidth = (rashin rafi + babban rafi) * adadin tashoshi * 1.2:

① Ƙimar bandwidth> 70M, yi amfani da gigabit;

② Darajar bandwidth

Tambaya 1: Tsarin lissafin rafin lambar a bayyane yake, amma me yasa za a ninka shi da 1.2?

Domin bisa ga ka'idar sadarwa ta hanyar sadarwa, toshe fakitin bayanai shima yana bin ka'idar TCP/IP, kuma sashin bayanan yana buƙatar a sanya masa alama tare da filayen taken kowane Layer na yarjejeniya don watsa shi cikin kwanciyar hankali, don haka rubutun kuma zai mamaye wani yanki. wani kaso na sama.
