Musiyano pakati peLayer 2 uye Layer 3 network switch

Wese munhu anoziva chimwe chinhu nezve Layer 2 uye Layer 3 network, asi yakawanda sei yaunoziva nezvekusiyana kuri pakati pavo?JHATechr ichakutora iwe kuburikidza nazvo.

1. Layer2

Iyo Layer2 network chimiro modhi ine chete musimboti layer uye yekupinda layer iri nyore kushanda. Iyo switch inoendesa mberi data pakiti zvinoenderana neMAC kero tafura.

Kana pane chero, ichaendeswa mberi, kana zvisingaiti, ichafukidzwa, ndiko kuti, data packet ichaparadzirwa kune dzose ports. Kana iyo nzvimbo yekuenda ikagamuchira mhinduro, switch inogona kuwedzera kero yeMAC patafura yekero. Iyi ndiyo nzira iyo switch inosimbisa iyo MAC kero. process.

Nekudaro, kutepfenyura kwakadaro kwemapaketi edata ane zvibodzwa zvisingazivikanwe zveMAC zvinokonzeresa dutu guru retiweki mune yakakura-chiyero network yekuvaka. Izvi zvakare zvinomisa zvakanyanya kuwedzera kweyechipiri-layer network. Naizvozvo, iyo Layer2 network Iyo network yekugona ishoma, saka ivo vanowanzo shandiswa kuvaka maLAN madiki.

2. Layer3

Yakasiyana neiyo Layer2 network, iyo Laye3 network dhizaini inogona kuunganidzwa mumahombe-makuru network.

Iyo yepakati layer ndiyo inotsigira musana uye data yekufambisa chiteshi chese network, uye kukosha kwayo kunozviratidza.

Naizvozvo, mune yese Layer3 network chimiro, iyo yepakati layer ine yepamusoro yemidziyo zvinodiwa. Inofanirwa kuve yakashongedzerwa neyepamusoro-inoshanda data redundant switching zvishandiso uye mutoro wekuenzanisa midziyo kudzivirira kuwandisa, kuitira kuderedza huwandu hwe data inotakurwa nechero core layer switch.

JHA Tech, ndivo vagadziri vepakutanga vakatsaurirwa kuR&D, kugadzira, uye kutengesaEthernet Switchs, Media Converter, PoE Switch&Injector uyeSFP moduleuye akawanda ane hukama zvigadzirwa zve17 makore. Tsigira OEM, ODM, SKD uye zvichingodaro.

Iyo software inotsigira JHA Tech yakagadziriswa switch, L2 uye L3 ndiyo yakafanana software inoshanda sisitimu, iyo inounza nyore kune vatengi. Mufananidzo uri pamusoro unoratidza mabasa ekugadzirisa ayo JHA Tech anogona kuwana nesoftware interface.

BUGs dzakasimudzwa panzvimbo inogona kugadziriswa mukati memaminitsi makumi matatu pakutanga. Zvinhu zvitsva zvakakumbirwa nevatengi zvinogona kuburitswa sekusimudzira mapakeji mukati memazuva manomwe pakutanga. Hapazovi nekuwedzera mari yekusimudzira.

Iwe une mibvunzo nezve mashandisiro eChinja, kana kuti unoda kutenga mamwe mamodheru kukwezva vatengi vakawanda? Kana iwe uchida chero rubatsiro, ndapota siya email kero yako uye isu tichava nenyanzvi yekukubata iwe kune imwe-pane-mhinduro.
