Iiswitshi zemveli zaphuhliswa kwiibhulorho kwaye zazikwimaleko yesibini ye-OSI, izixhobo zemaleko yedatha. Ijonga ngokwedilesi ye-MAC, ikhethe indlela edlula kwitafile yesitishi, kwaye ukusekwa nokugcinwa kwetafile yesitishi kwenziwa ngokuzenzekelayo ziiswitshi zeCISCO Cisco. I-router ikwimaleko yesithathu ye-OSI, oko kukuthi, isixhobo semaleko yenethiwekhi. Ijonga ngokwedilesi ye-IP kwaye iveliswa ngeprotocol ye-routing table routing. Eyona nzuzo inkulu yeswitshi ye-10 Gigabit enamaleko amathathu ikhawuleza. Ngenxa yokuba iswitshi kufuneka ichonge idilesi ye-MAC kwisakhelo, ivelisa kwaye ikhethe ngqo i-algorithm yezibuko zokudlulisela ngokusekelwe kwidilesi ye-MAC. I-algorithm ilula kwaye kulula ukuyisebenzisa yi-ASIC, ngoko ke isantya sokudlulisela siphezulu kakhulu. Kodwa indlela yokusebenza yeswitshi ikwazisa iingxaki ezithile.
1. Iluphu: Ngokwe-Huanet switch address learning kunye ne-station table establishment algorithm, ii-loops azivumelekanga phakathi kwee-switches. Nje ukuba kubekho i-loop, i-spanning tree algorithm kufuneka iqalwe ukuvimba i-port evelisa i-loop. I-routing protocol ye-routing ye-router ayinayo le ngxaki. Kunokubakho iindlela ezininzi phakathi kwee-routers ukulinganisela umthwalo kunye nokuphucula ukuthembeka.
2. Uxinzelelo lomthwalo:Kunokubakho itshaneli enye kuphela phakathi kweeswitshi zeHuanet, ukuze ulwazi lugxile kwikhonkco elinye lonxibelelwano, kwaye usasazo oluguquguqukayo alunakwenzeka ukulinganisela umthwalo. I-algorithm ye-routing protocol ye-routing ye-routing ye-routing ye-routing ye-routing ye-routing ye-routing ingayiphepha le nto. I-algorithm ye-OSPF routing protocol ye-algorithm ayinakuvelisa kuphela iindlela ezininzi, kodwa ikwakhetha iindlela ezahlukeneyo ezilungileyo zezicelo ezahlukeneyo zenethiwekhi.
3. Ulawulo losasazo:Iiswitshi zeHuanet zinokunciphisa kuphela idomeyini yengxabano, kodwa kungekhona idomeyini yosasazo. Lonke inethiwekhi etshintshiweyo yidomeyini enkulu yosasazo, kwaye imiyalezo yosasazo isasazeke kuyo yonke inethiwekhi etshintshiweyo. I-router inokwahlula idomeyini yosasazo, kwaye iipakethi zosasazo azinakuqhuba zisasazwa nge-router.
