Cffiberlink ine mutsara wakapfuma wekugovera uye wekutumira chigadzirwa, kusanganisira indasitiri-giredhi inogadziriswa switch ye5G optical fiber yekutaurirana michina, yakangwara POE, network switch, uye SFP optical modules. Pakati pavo, iyo switch chigadzirwa mutsara wega watanga anopfuura zana modhi.
Kune akawanda mamodheru, uye hazvidzivisike kuti pachave nenguva dzaunenge uchipenya.
Nhasi, isu tichagadzirisa zvakarongeka nzira yekusarudza yekuchinja iwe.
01【Sarudza Gigabit kana 100M】
Munetiweki yevhidhiyo yekutarisa sisitimu, yakawanda inoenderera yevhidhiyo data inoda kufambiswa, izvo zvinoda kuti shanduko ive nekukwanisa kuenderera mberi data. Iyo yakawanda makamera akabatanidzwa kune switch, inowedzera huwandu hwe data inoyerera kuburikidza nekuchinja. Tinogona kufungidzira kodhi inoyerera sezvo mvura ichiyerera, uye maswiti ndiwo majunisheni ekuchengetedza mvura imwe neimwe. Kana mvura inoyerera yadarika mutoro, dhamu rinoputika. Saizvozvo, kana huwandu hwe data inotumirwa nekamera pasi pekuchinja ichipfuura kugona kwekufambisa kwechiteshi, ichaitawo kuti chiteshi chirase huwandu hwe data uye kukonzera matambudziko.
Semuenzaniso, 100M switch yekuendesa data data inodarika 100M inokonzeresa kuwanda kwekurasikirwa kwepaketi, zvichikonzera chiitiko cheblurred screen uye kunamatira.
Saka, mangani makamera anoda kubatanidzwa kune gigabit switch?
Pane chiyero, tarisa huwandu hwe data inotumirwa nechiteshi chepamusoro chekhamera: kana huwandu hwe data inotumirwa nechiteshi chepamusoro ichipfuura 70M, sarudza gigabit port, ndiko kuti, sarudza gigabit switch kana gigabit. uplink switch
Heino kukurumidza kuverenga uye nzira yekusarudza:
Bandwidth value = (sub-stream + main stream) * nhamba yematanho * 1.2
①Bandwidth value>70M, shandisa Gigabit
②Bandwidth kukosha <70M, shandisa 100M
Semuenzaniso, kana paine switch yakabatana ne20 H.264 200W makamera (4 + 1M), zvino maererano nekuverenga uku, chiyero chekutumira cheuplink port ndeye (4 + 1) * 20 * 1.2 = 120M > 70M, munyaya iyi, gigabit switch inofanira kushandiswa. Mune zvimwe zviitiko, chiteshi chimwe chete chekuchinja chinoda kuva gigabit, asi kana iyo system system isingagone kugadziridzwa uye traffic inogona kuenzana, ipapo gigabit switch kana gigabit uplink switch inodiwa.
Mubvunzo 1: Nzira yekuverenga yekodhi yekodhi yakajeka, asi sei uchiiwedzera ne 1.2?
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 kamera 4M bit rate, 2M bit rate, etc. isu tinowanzo taura nezvayo tichireva saizi yechikamu chedata. Zvinoenderana nehuwandu hwekutaurirana kwedata, iyo yepamusoro yemusoro inoverengera inosvika makumi maviri muzana, saka iyo fomula inoda kuwanzwa ne 1.2.
Saka, mangani makamera anoda kubatanidzwa kune gigabit switch?
Pane chiyero, tarisa huwandu hwe data inotumirwa nechiteshi chepamusoro chekhamera: kana huwandu hwe data inotumirwa nechiteshi chepamusoro ichipfuura 70M, sarudza gigabit port, ndiko kuti, sarudza gigabit switch kana gigabit. uplink switch.
