Ukutshintshwa kwe-core layer isetyenziselwa ukhetho lwendlela kunye nokuhanjiswa kwesantya esiphezulu, ukubonelela ngesakhiwo sokuhanjiswa kwe-backbone ephuculweyo kwaye ethembekileyo, ngoko ke isicelo sokutshintshwa kwe-core sinokuthembeka okuphezulu kunye nokugqithisa.Iswitshi yomaleko odityanisiweyo yindawo yokudibanisa yofikelelo oluninzi.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 wokutshintshwa koluhlu lokufikelela kukudibanisa umsebenzisi wokugqibela kuthungelwano, ngoko ke ukutshintshela umaleko wokufikelela kuneempawu zeendleko eziphantsi kunye nobuninzi be-port.
Umahluko wokusebenza
I-core switch layer yi-Layer 3 switch ene-speed-speed-forward, i-interface yomthamo omkhulu we-bandwidth (efana ne-10-gigabit interface), kunye nokukwazi ukucwangcisa i-backplane enkulu.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.Ngamafutshane, iziphumo zokuthelekisa ukusebenza kwezi zitshintshi zithathu zezi: iswitshi engundoqo yomaleko> I-Aggregation layer switch> Fikelela umaleko wokutshintsha.
Sebenzisa umahluko wemeko
Akukho mfuneko esisigxina yokutshintsha umaleko ongundoqo, iswitsha yomaleko odibeneyo kunye nokufikelela kwi-maleko, yeyiphi umaleko abakuyo ubukhulu becala ixhomekeke kubungakanani bendawo yothungelwano kunye nokukwazi ukudlulisa isixhobo, ayizizo zonke inethiwekhi kufuneka zibe nezi zakhiwo zintathu, amanye amashishini afikelela kuphela kwi-switch layer kunye ne-core layer switch, enye yeenjongo zale ndlela kukugcina iindleko.
Umahluko osebenzayo phakathi komgangatho wofikelelo, i-aggregation layer kunye ne-core switch switch ngamanqaku aphambili olwazi olungentla.Ngokubhekiselele kwiiswitshi ezikhankanywe ngasentla, ziimveliso zonxibelelwano ezidumileyo eShenzhen HDV Phoeletron Technology LTD., ezinje: Ethernet switch, iFayibha iswitshi, i-Ethernet iFayibha iswitshi, njl., ezi zitshintshi zingentla zingasetyenziswa kwiindawo ezahlukeneyo, ukubonelela. ukhetho oluninzi lwabasebenzisi abaneemfuno ezahlukeneyo, wamkelekile ukuza kuqonda, siya kubonelela ngenkonzo esemgangathweni.
