Ngophuhliso jikelele kunye nokusetyenziswa kobuchwephesha bothungelwano, uphuhliso lotshintshiselwano luphinde lwenze utshintsho olukhulu. Olona tshintsho lwakuqala luphuhliswe ukusuka kutshintsho olulula kakhulu ukuya kumaleko wesi-2, kwaye emva koko ukusuka kumqolo wesi-2 ukuya kumaleko wesi-3. Ngoko ke, yintoni aUluhlu lwesi-3 sokutshintsha?

Uluhlu lwe-3 lokutshintshangenene iThekhinoloji yokutshintsha iLayer 2 + Itekhnoloji yokudlulisa iLayer 3. Oku akuthethi ukuba kukho "imigangatho emithathu" yokutshintsha. Aumaleko 3 tshintshalutshintsho olunemisebenzi yerouter. Eyona njongo ibalulekileyo yeUluhlu lwesi-3 sokutshintshakukwenza lula utshintshiselwano lwedatha ngaphakathi kweLAN enkulu. Umsebenzi womzila onawo ukwabonelela ngeenkonzo zale njongo, kwaye unokuhanjiswa kube kanye kwaye ugqithiselwe amaxesha amaninzi.

Ukutshintsha iteknoloji kwingqiqo yendabuko isebenza kumgangatho wesibini we-OSI imodeli yenethiwekhi eqhelekileyo-idatha yekhonkco yedatha, ngelixa iteknoloji yokutshintsha itekhnoloji emithathu igqiba ukuhanjiswa kwepakethi yedatha kwinqanaba lesithathu lemodeli yenethiwekhi. Iikhonkco zamaxesha athile ezifana nokuhanjiswa kwepakethi yedatha zigqitywe ngokukhawuleza nge-hardware, kodwa iinkonzo ezifana nokuphuculwa kolwazi lwendlela, ukugcinwa kwetafile yokucwangcisa, ukubala umzila, kunye nokuqinisekiswa komzila kugqitywe ngesofthiwe. Ayinakuqonda kuphela umsebenzi wothungelwano wothungelwano, kodwa ikwaqinisekisa ukusebenza kakuhle kwenethiwekhi yeemeko ezahlukeneyo zenethiwekhi.
