Kugirango ubashe kwikorera urusobe rwimikorere ya sisitemu yo kugenzura amashusho, sisitemu ikenera kugera kuri kamera nyinshi, kandi nini nini yamakuru yamakuru. Ihindura igomba kuba ifite ubushobozi buhamye bwo guhindura amakuru kugirango yohereze umubare munini kandi uhoraho wa Data. None, guhindura ethernet bigomba guhitamo 100M cyangwa 1000M?

Amakuru yatanzwe kuri buri gihe mugihe cyo kohereza amakuru yitwa code stream, niba umubare wamakuru yoherejwe na kamera munsi ya switch irenze ubushobozi bwo kohereza icyambu runaka, bizanatuma iki cyambu kijugunya amakuru menshi kandi bitera ibibazo.

Kurugero, 100M ihinduranya ikohereza amakuru arenze 100M, bizatera igihombo kinini cyapaki, bikavamo ecran ya ecran. None, ukeneye kamera zingahe ukeneye guhitamo gigabit?

Hano haribisanzwe, ukurikije umubare wamakuru yoherejwe nicyambu cya kamera cyo hejuru: niba umubare wamakuru yoherejwe nicyambu cya uplink arenze 70M, hitamo icyambu cya gigabit, ni ukuvuga, hitamo gigabit cyangwa gigabit uplink switch .

Hariho uburyo bwihuse bwo kubara no guhitamo: umurongo mugari = (sub stream + umugezi nyamukuru) * umubare wimiyoboro * 1.2:

Value Umuyoboro mugari> 70M, koresha gigabit;

ValueUbunini bwagutse

Ikibazo 1: Gahunda yo kubara kode yumurongo irasobanutse neza, ariko kuki igomba kugwizwa na 1.2?

Kuberako ukurikije ihame ryitumanaho ryurusobe, enapsulation yamakuru yamapaki nayo akurikiza protocole ya TCP / IP, kandi igice cyamakuru kigomba gushyirwaho numutwe wimirima ya buri protocole kugirango yandurwe neza, bityo umutwe nawo uzatwara a igipimo runaka cyo hejuru.
Igipimo cya 4M bit na 2M biti ya kamera dukunze kuvuga bivuga ubunini bwigice cyamakuru. Ukurikije igipimo cyitumanaho ryamakuru, umutwe urenze hafi 20%, bityo formula igomba kugwizwa na 1.2.

Ikibazo 2: Kuki 70M itari 100M?

Ahanini kugirango dusuzume ibinyabiziga biturika. Amashusho yamakuru ya videwo agizwe namakadiri menshi. Amakuru asa nkaho yoroshye mubyukuri afite amakuru menshi ako kanya. Iki kibazo gisaba guhinduranya kuri buffer no gukosora ihindagurika ryamakuru.
Guhindura ububiko-imbere-kubika-imbere-imbere aya makuru, birasabwa rero kubika bimwe. Mugushushanya umuyoboro uhindura, hashobora kubaho 30% -40%. Ku cyambu cya 100M, birasabwa ko urujya n'uruza rutarenga 70M.
