The core layerchinjainonyanya kushandiswa pakusarudza nzira uye kumhanyisa-kumhanya, ichipa yakagadziridzwa uye yakavimbika musana wekufambisa dhizaini, saka iyo yakakosha layer.chinjaapplication ine yakakwirira kuvimbika uye throughput. The aggregation layerchinjandiyo nzvimbo yekubatanidza yeakawanda yekupinda layer switch. Inoshanda seyakabatana egress yeA-Nodes, kutumira uye nzira yekusarudza. Inofanira kukwanisa kubata yese traffic kubva kune yekuwana layer zvishandiso uye nekupa uplink kune yakakosha layer. Basa rekuwana layerchinjandeyekubatanidza mushandisi wekupedzisira kune network, saka iyo yekupinda layerchinjaine maitiro emutengo wakaderera uye yakakwira port density.
Musiyano wekuita
The core layerchinjairi Layer 3chinjane-high-speed kutumirwa, yakakura-inogadzirisa interface bandwidth (yakadai se 10-gigabit interface), uye yakakura backplane yekugadzirisa kukwanisa. Naizvozvo, kuita kwayo kwakakwira kupfuura kuya kweaggregation layer switch uye kuwana layer switch. Aggregation switch inewo mamwe mabasa ekufambisa uye anogona kuve Layer 2 kana Layer 3 switch. Switch switch iLayer 2 switch. Naizvozvo, aggregation switch ine mashandiro epamusoro, madoko mashoma, uye mitengo yakakwira pane yekuwana switch. Muchidimbu, mhedzisiro yekufananidza kwekuita kweava matatu switch ndeiyi: core layerchinja> Aggregation layerchinja> Access layerchinja.
Shandisa scenario musiyano
Hapana chinodiwa chakagadziriswa cheiyo core layerchinja, aggregation layerchinjauye access layerchinja, iyo layer yavanenge vari kunyanya inoenderana nehukuru hwetiweki nharaunda uye kugona kutumira kwechishandiso, kwete network yese inofanirwa kunge iine zvimiro zvitatu izvi, mamwe mabhizinesi anongowana layer.chinjauye core layerchinja, chimwe chezvinangwa zveiyi nzira kuchengetedza mari.
Misiyano yekushanda pakati pekuwana layer, aggregation layer uye core layer switch ndiwo mapoinzi akakosha eruzivo rwuri pamusoro. Kana ari maswichi ataurwa pamusoro apa, iwo akakurumbira kutaurirana zvigadzirwa muShenzhen HDV Phoeletron Technology LTD., senge: Ethernetchinja, Fiberchinja, Ethernet Fiberchinja, zvichingodaro, shanduko dziri pamusoro dzinogona kushandiswa munzvimbo dzakasiyana siyana, kupa sarudzo dzakawanda kune vashandisi vane zvinodiwa zvakasiyana, kugamuchirwa kuti vauye kuzonzwisisa, isu tichapa yakanakisa mhando sevhisi.
