Maswichi echinyakare akagadzirwa kubva pamabhiriji uye aive echikamu chechipiri cheOSI, iyo data link layer equipment. Anobata zvinoenderana nekero yeMAC, anosarudza nzira inopinda nepa station table, uye kugadzwa nekugadzirisa station table kunoitwa otomatiki neCISCO Cisco switches. Router ndeyechikamu chechitatu cheOSI, kureva, network layer device. Anobata zvinoenderana neIP address uye anogadzirwa kuburikidza nerouting table routing protocol. Chinhu chikuru che three-layer 10 Gigabit switch inokurumidza. Nekuti switch inongoda kuziva kero yeMAC mufuremu, inogadzira zvakananga uye inosarudza forwarding port algorithm zvichibva paMAC address. Algorithm iri nyore uye iri nyore kushandisa neASIC, saka forwarding speed yakanyanya. Asi mashandiro eswitch anounzawo mamwe matambudziko.
1. Chitenderedzo: Zvinoenderana neHuanet switch address learning uye station table establishment algorithm, ma loop haatenderwe pakati pema switch. Kana pangove ne loop, spanning tree algorithm inofanira kutanga kuvharira port inogadzira loop. Routing protocol yerouter haina dambudziko iri. Panogona kuva nenzira dzakawanda pakati pema routers kuti mutoro uenzane uye kuvandudza kuvimbika.
2. Kuisa mutoro muzvikamu:Panogona kuva nechiteshi chimwe chete pakati pemaswichi eHuanet, kuitira kuti ruzivo rwuve rwakatarisana pane imwe link yekutaurirana, uye kugoverwa kwesimba hakugoneke kuenzana kwemutoro. Algorithm yerouting protocol yerouting yerouter inogona kudzivirira izvi. Algorithm yeOSPF routing protocol haingogone kugadzira nzira dzakawanda chete, asiwo kusarudza nzira dzakasiyana dzakanakisa dzemapurogiramu akasiyana enetwork.
3. Kudzora nhepfenyuro:Huanet switches inogona chete kuderedza conflict domain, asi kwete broadcast domain. Switched network yese inzvimbo yakakura yebroadcast, uye mameseji ebroadcast akapararira mu switched network yese. Router inogona kuparadzanisa broadcast domain, uye mapaketi ebroadcast haagone kuramba achiburitswa kuburikidza nerouter.
