Nekuvandudzwa kwakajairwa uye kushandiswa kwetiweki tekinoroji, kuvandudza kwekuchinja kwaitawo shanduko huru.Maswichi ekutanga akagadzirwa kubva kune akareruka achinja kuenda ku layer 2 switch, uyezve kubva pa layer 2 switch to layer 3 switch.Saka, chii chinonzi aLayer 3 switch?

Layer 3 switchari chaizvo Layer 2 switching tekinoroji + Layer 3 yekufambisa tekinoroji.Hazvireve kuti kune "matatu akaturikidzana" ekuchinja.Alayer 3 chinjais a switch ine mamwe mabasa router.Chinangwa chinonyanya kukosha cheLayer 3 switchndeye kufambisa shanduko yedata mukati meLAN hombe.Basa rekufambisa rainaro rinopawo masevhisi echinangwa ichi, uye rinogona kufambiswa kamwe chete uye kutumirwa kakawanda.

Kushandura tekinoroji nenzira yechinyakare kunoshanda pachikamu chechipiri cheOSI network standard modhi-iyo data link layer, nepo matatu-layer switching tekinoroji inopedzisa kumhanyisa-kumhanya kwemapaketi edata pachikamu chechitatu chemuenzaniso wetiweki.Periodic links senge data packet kutumira zvinokurumidza kupedzwa nehardware, asi masevhisi akadai sekusimudzira ruzivo rwekusimudzira, kugadzirisa tafura yenzira, kuverenga kwenzira, uye kusimbiswa kwenzira kunopedzwa nesoftware.Iyo haigone chete kuona iyo network routing basa, asi zvakare ive nechokwadi chekuita kwakanakisa network kune akasiyana network mamiriro.
