Kuti ukwanise kurodha iyo inowedzera kuomarara vhidhiyo yekutarisa system network, switch inoda kuwana mamwe makamera, uye yakakura iyo data data yekuchinja. Iyo switch inofanirwa kuve yakagadzikana kwazvo kugona kushandura data kuti itumire yakakura uye inoenderera Vhidhiyo data. Saka, iyo ethernet switch inofanira kusarudza 100M kana 1000M?

Iyo data inofambiswa panguva yeyuniti panguva yekufambisa data inonzi code stream, kana huwandu hwe data inotumirwa nekamera pasi pe switch inodarika simba rekufambisa reimwe chiteshi, ichaitawo kuti chiteshi ichi chirase huwandu hwakawanda hwe data uye. kukonzera matambudziko.

Semuenzaniso, 100M switch inoendesa mberi data volume inodarika 100M, izvo zvinokonzeresa kuwanda kwekurasikirwa kwepaketi, zvichikonzera kutonhora kwescreen. Saka, mangani makamera aunoda kusarudza gigabit switch?

Pane chiyero, zvichienderana nehuwandu hwe data inotumirwa nekamera uplink port: kana huwandu hwe data inotumirwa neuplink port yakakura kudarika 70M, sarudza gigabit port, kureva, sarudza gigabit switch kana gigabit uplink switch. .

Pane kukurumidza kuverenga uye nzira yekusarudza: bandwidth kukosha = (sub stream + main stream) * nhamba yezviteshi * 1.2:

① Bandwidth kukosha> 70M, shandisa gigabit;

②Bandwidth kukosha

Mubvunzo 1: Iyo kodhi yekuyerera kwekuverenga maitiro akajeka kwazvo, asi nei ichifanira kuwanzwa ne1.2?

Nekuti maererano nemusimboti wekutaurirana kwenetiweki, iyo encapsulation yemapaketi edata zvakare inotevera TCP/IP protocol, uye chikamu chedata chinoda kucherechedzwa nemusoro minda yeimwe neimwe protocol layer kuti ifambiswe zvakanaka, saka musoro unozogarawo. imwe chikamu chepamusoro.
Iyo 4M bit rate uye 2M bit rate yekamera yatinowanzo kutaura nezvayo inoreva saizi yechikamu chedata. Zvinoenderana nereshiyo yekukurukurirana kwedata, musoro wepamusoro unoverengera makumi maviri muzana, saka fomula inofanirwa kuwanzwa ne1.2.

Mubvunzo 2: Sei 70M isiri 100M?

Kunyanya kufunga nezvekuputika traffic. Vhidhiyo data stream inoumbwa neakawanda mafuremu. Iyo inoratidzika kunge yakatsetseka data rwizi inonyatso ine akawanda nekukurumidza kuputika kwedata. Aya mamiriro anoda switch kune buffer uye kugadzirisa kushanduka kwe data.
Iyo switch inochengeta-mberi-chitoro-mberi aya data, saka zvinokurudzirwa kuve nekumwe chengetedzo. Paunenge uchigadzira iyo switching network, panogona kuve ne30% -40% kuchengetedza. Kune 100M chiteshi, zvinokurudzirwa kuti traffic yekutumira isapfuure 70M.
