Iyo ring network switch inoshanda pane data link layer, ine yakakwira-bandwidth kumashure bhazi uye yemukati switching matrix.Mushure mekunge dunhu rekutonga ragamuchira pakiti yedata, chiteshi chekugadzirisa chinotarisa kumusoro kwekero referensi tafura mundangariro kuti uone kuti ndechipi chiteshi chetiweki kadhi (network kadhi) yechinangwa MAC (network kadhi hardware kero) yakabatana.Mapaketi edata anokurumidza kuendeswa kunzvimbo yekuenda kuburikidza nemukati switching matrix.Kana chinangwa cheMAC chisipo, chichatepfenyurwa kumadoko ese.Mushure mekugamuchira mhinduro yechiteshi, iyo ring network switch "ichadzidza" kero itsva yeMAC uye woiwedzera kutafura yekero yeMAC yemukati.Zvinogonekawo kushandisa ring network switch ku "segment" network.Nokuenzanisa iyo IP kero tafura, iyo ring network switch inobvumira chete inodiwa network traffic kuti ipfuure nepakati ring network switch.Kuburikidza nekusefa uye kutumirwa kweiyo ring network switch, iyo collision domain inogona kunyatso kuderedzwa, asi network layer nhepfenyuro haigone kuve. yakakamurwa, ndiko kuti, nzvimbo yekutepfenyura.

Loop switch port.Iyo loop switch inogona kufambisa data pakati peakawanda port pairi panguva imwe chete.Chiteshi chega chega chinogona kutorwa sechikamu chakasiyana chetiweki (Cherechedza: isiri-IP network segment).Midziyo yeNetwork yakabatana nayo inogona kunakidzwa nebandwidth yese pasina kukwikwidzana nemimwe michina.Kana node A inotumira data kune node D, node B inogona kutumira data kune node C panguva imwe chete, uye node mbiri dzinofarira bandwidth yese yetiweki uye ine yavo. own virtual connections.Kana 10Mbps Ethernet ring network switch ikashandiswa, kuyerera kwese kwe ring network switch yakaenzana ne 2*10Mbps=20Mbps.Kana 10Mbps yakagovaniswa hub inoshandiswa, kuyerera kwese kwehubhu hakupfuuri 10Mbps. Muchidimbu, rin'i inoshandura ndeye network network inoenderana nekuzivikanwa kwekero yeMAC, iyo inogona kupedzisa encapsulation uye kutumira mabasa e data data.Iyo ring switch inogona "kudzidza" kero yeMAC uye kuichengeta mutafura yekero yemukati.Nekumisikidza nzira yenguva pfupi yekuchinja pakati peanotanga uye anogashira anogashira data data, furemu yedata inogona kusvika zvakananga kero yakanangwa kubva kukero yekunobva.

Mhete switch drive.Iyo nzira yekufambisa yeinoshandura mhete yakazara-duplex, hafu-duplex, yakazara-duplex/hafu-duplex adaptive.Iyo yakazara duplex yemhete network switch inoreva kuti ring network switch inogona kugamuchira data uchitumira data.Matanho maviri aya anowiriraniswa, sezvatinowanzo taura, tinokwanisawo kunzwa izwi remumwe nemumwe patinotaura.Yese ring switch inotsigira duplex yakazara.Zvakanakira zvizere duplex kunonoka kudiki uye nekukurumidza kumhanya.

Kana tichitaura nezve yakazara-duplex, hatigone kufuratira imwe pfungwa ine hukama zvakanyanya nayo, kureva, "half-duplex."Iyo inonzi hafu-duplex inoreva kuti chiito chimwe chete chinoitika munguva yenguva.Somuenzaniso, nzira nhete inogona kungopfuura motokari imwe chete panguva imwe chete.Kana mota mbiri dzichityaira dzakatarisana, chiyero chimwe chete chinogona kutorwa munyaya iyi.Uyu muenzaniso unoratidza musimboti wehafu-duplex.Ekutanga mawalkie-talkies uye mahubs ekutanga aive hafu-duplex zvigadzirwa.Nekuenderera mberi kwekufambira mberi kwehunyanzvi, iyo hafu-kaviri mubatanidzwa yakabuda zvishoma nezvishoma kubva padanho renhoroondo.
