Nzira yakadini inoshandiswa kuenzanisa ne hubs uye routers
A network switch is a device hardware device that centralizes communication between multiple devices in one area area network (LAN) .
Mamiriyoni e-switching Ethernet maitiro aigara achishandiswa pamakambani epamba makore akawanda mapuraneti asati apinda mumba akazozivikanwa. Misha yemazuva ano ma routers inobatanidza Ethernet switches zvakananga muuniti seimwe yemabasa avo epamusoro.
Kushanda kwenhepfenyuro yemagetsi kushandiswa zvakanyanya mumakambani emakambani uye nharaunda. Masoko emitambo dzimwe nguva anonzi kushandura hubs, kubata hubs kana mabhiriji eMAC.
About Network Switches
Apo kushandura humwe huripo kune huwandu hwemhando dzemasiterendi kusanganisira ATM , Fiber Channel , uye Token Ring , Ethernet switches ndiyo inowanzosiyana.
Mainstream Ethernet switches seyavo vari mukati ma router roubandaneti vanotsigira Gigabit Ethernet kukurumidza kuburikidza nehumwe humwe hukama, asi kushandiswa kwepamusoro-soro kufanana nevaya vari munzvimbo dzinochengetedza dare vanowanzotsigira 10 Gbps kuburikidza.
Mhando dzakasiyana dze network network switches rubatsiro rwakasiyana-siyana rwezvinhu zvakabatana. Vatengi-gorosi network switch inopa hutano kana hupfumi hwemaEthernet, asi kushandiswa kwekambani kunowanzotsigira pakati pekubatana kwe 32 ne128.
Shanduro inogona kuwedzera kuve yakabatana kune imwe neimwe, nzira ye-daisy-chaining yekuwedzera nhamba inowedzera zvishoma yezvigadzirwa kuLAN.
Kugadziriswa uye kusina kugadziriswa Switch
Basic network switches yakafanana neaya inoshandiswa mumagetsi evatengi inoda kusarudzwa kwakasarudzwa kudarika kubudiswa mumatare uye simba.
Kana ichienzaniswa nemasikirwo aya asina kushandiswa, mapuraneti ekupedzisira ekushandiswa anoshandiswa pamakambani emakambani anotsigira hukuru hwezvinhu zvakagadzirirwa zvakagadzirirwa kuti zvidzorwe nemuongorori mutungamiri. Zvinhu zvakakurumbira zvinoshandiswa zvinoshandiswa zvinosanganisira SNMP kuongorora, link aggregation, uye kutsigira kweKoS .
Kugadziriswa kwetsika kunokonzerwa kunotungamirirwa kubva ku Unix-style command line interfaces. Chimwe chitsva chegadziriro yakagadzirika inonzi smart switches, inotarisirwa pakunopinda-level uye midrange business enterprise, sangano web-based interfaces rakafanana neimba router.
Network Switches vs. Hubs uye Routers
A network inoshandura muviri inofanana nehutaneti . Kusiyana nematumba, zvisinei, network switches inokwanisa kuongorora mishumo inopinda sezvavanogamuchirwa uye ichivatungamirira pane imwe nzvimbo yekutumira-teknolojia inonzi packet switching .
Shanduko inotarisa nzvimbo uye nzvimbo dzekuenda mazita epaji rimwe nerimwe uye inotumira dheti chete kune zvigadzirwa zvakananga, apo hubs inotumira mapeti kumatokari ose kunze kweiye akagamuchira muthara. Inoshanda nenzira iyi kuchengetedza network bandwidth uye kazhinji kuvandudza kushanda kuenzaniswa nehubs.
Shanduko dzinoitawo sehwe routers network. Kunyange zvazvo routers uye shanduko mbiri dzinoita kuti hutano hwepakombiyuta huvepo, ma routers chete ane rubatsiro rwekubatanidza kune dzimwe nhengo dzeduzhinji, zvichida mitambo yemunharaunda kana internet.
Chitsauko 3 Shanduka
Traditional network switches inoshandiswa paDheta 2 Data Link Layer yemuenzaniso weOSI . Chitsauko 3 shanduko inosanganisa manzwiro edziviriro edziviriro e-switches uye routers mujecha re hybridhi zvakare yakave yakashandiswa mune dzimwe nzvimbo dzebhizimusi.
Inofananidzwa nemasikirwo emasikirwo, Shanduro 3 shinje inopa rubatsiro rwakanaka rwekugadzirisa kwemaLAN (VLAN).
