Ngokuqhelekileyo, inxalenye yenethiwekhi eqhagamshelwe ngokuthe ngqo kubasebenzisi okanye ifikelele kwinethiwekhi ibizwa ngokuba ngumaleko wokufikelela, kwaye inxalenye phakathi komgangatho wokufikelela kunye ne-core layer ibizwa ngokuba yi-distribution layer okanye i-convergence layer.Ukutshintsha kokufikelela ngokuqhelekileyo kusetyenziselwa ukudibanisa ngokuthe ngqo iikhomputha, kunye nokutshintsha kokudibanisa ngokuqhelekileyo kusetyenziswa phakathi kwezakhiwo.Ukuhlangana kuyalingana nesikhululo sezothutho sengingqi okanye esibalulekileyo, kwaye undoqo ulingana nokuphuma okanye udibaniso lulonke.Injongo yenkcazo yoqobo yoluhlu lokudibanisa kukunciphisa umthwalo kumbindi, ukutshintshiselana ngokutshintshiselana kwedatha yendawo kwi-aggregation switch yendawo, ukunciphisa umthwalo womsebenzi we-core layer, kwaye wenze umaleko ongundoqo kuphela inkqubo yotshintshiselwano lwedatha ngaphandle indawo yendawo.

Aukutshintshela umaleko wokuhlanganisa

Iswitshi yomaleko wokudityaniswa yindawo yokudibanisa yofikelelo lofikelelo oluninzi.Umsebenzi wayo kukudibanisa ukuphuma kweendawo zokungena, kwaye yenza ugqithiso kunye nendlela.Kufuneka ikwazi ukuphatha yonke i-traffic ukusuka kwizixhobo zofikelelo kunye nokubonelela nge-uplinks ukuya kumaleko angundoqo, ngoko ke ukutshintshwa kwe-aggregation layer kufuneka ibe nomsebenzi ophezulu wokugqithisela xa kuthelekiswa nokutshintshela umaleko wokufikelela, oqhelekileyoumaleko 3 tshintsha.
