Umaleko ongundoqotshintshaisetyenziswa ikakhulu kukhetho lwendlela kunye nesantya esiphezulu, ukubonelela ngesakhiwo esiphuculweyo nesithembekileyo sokuhambisa umqolo, ngoko ke umaleko ongundoqo.tshintshaisicelo sinokuthembeka okuphezulu kunye nokuphumelela. Umaleko wokudibanisatshintshayindawo yokudibanisa yofikelelo oluninzi lokutshintsha. Isebenza njengokuphuma okudityanisiweyo kwee-A-Nodes, ukuthunyelwa nokukhetha kwendlela. Kufuneka ikwazi ukuphatha yonke i-traffic evela kwizixhobo zokufikelela kwinqanaba kwaye inike i-uplink kwi-core layer. Umsebenzi wofikelelo umalekotshintshakukudibanisa umsebenzisi wokugqibela kuthungelwano, ngoko ke umaleko wofikelelotshintshaineempawu zexabiso eliphantsi kunye nokuxinana kwezibuko eliphezulu.
Umahluko wokusebenza
Umaleko ongundoqotshintshaluLeya 3tshintshange-speed-speed-forward, i-bandwidth ye-interface enkulu (efana ne-10-gigabit interface), kunye nekhono elikhulu lokucwangcisa i-backplane. Ke ngoko, ukusebenza kwayo kuphezulu kunelo lokutshintsha kwe-aggregation layer kunye nokufikelela kwi-switch switch. Iiswitshi ezidityanisiweyo nazo zinemisebenzi yomzila kwaye zinokuba ziLayer 2 okanye iLayer 3. Iiswitshi zofikelelo zizitshixo zeLayer 2. Ke ngoko, utshintsho oludityanisiweyo lunokusebenza okuphezulu, amazibuko ambalwa, kunye namazinga aphezulu kunokutshintsha kofikelelo. Ngokufutshane, iziphumo zokuthelekisa ukusebenza kwezi zitshintshi zithathu zezi: umaleko ongundoqotshintsha> Umaleko wodibanisotshintsha> Umaleko wofikelelotshintsha.
Sebenzisa umahluko wemeko
Akukho mfuneko ezinzileyo yomaleko ongundoqotshintsha, umaleko wokudityaniswatshintshakunye nofikelelo umalekotshintsha, ngowuphi umaleko abakuwo ikakhulu kuxhomekeke kubungakanani bokusingqongileyo kuthungelwano kunye nekhono logqithiso lesixhobo, ayizizo zonke inethiwekhi ezimele zibe nezi zakhiwo zithathu, amanye amashishini afikelele kuphela umaleko.tshintshakunye ne-core layertshintsha, enye yeenjongo zale ndlela kukugcina iindleko.
Umahluko osebenzayo phakathi komgangatho wofikelelo, i-aggregation layer kunye ne-core switch switch ngamanqaku aphambili olwazi olungentla. Ngokumalunga nokutshintsha okukhankanywe ngasentla, ziimveliso zonxibelelwano ezidumileyo eShenzhen HDV Phoeletron Technology LTD., ezinje: Ethernettshintsha, IFayibhatshintsha, IFayibha ye-Ethernettshintsha, njl., utshintsho olungentla lunokusetyenziswa kwiindawo ezahlukeneyo, ukunika ukhetho olungakumbi kubasebenzisi abaneemfuno ezahlukeneyo, bamkelekile ukuba baqonde, siya kubonelela ngenkonzo esemgangathweni.
