Tsika dzechinyakare dzakagadzirwa kubva kumabhiriji uye dzaive dzechipiri chikamu cheOSI, iyo data link layer midziyo.Inotaura zvinoenderana nekero yeMAC, inosarudza nzira kuburikidza netafura yechiteshi, uye kugadzwa uye kugadzirisa kwetafura yechiteshi kunongoitwa neCISCO Cisco switch.Iyo router ndeyechitatu chikamu cheOSI, kureva, network layer device.Inogadzirisa zvinoenderana neIP kero uye inogadzirwa kuburikidza neiyo routing tafura routing protocol.Iyo yakakura mukana weiyo matatu-layer 10 Gigabit switch inokurumidza.Nekuti iyo switch inongoda kuona iyo MAC kero mufuremu, inoburitsa zvakananga uye inosarudza yekutumira port algorithm zvichienderana nekero yeMAC.Iyo algorithm iri nyore uye iri nyore kuita neASIC, saka kumhanya kwekutumira kwakakwira zvakanyanya.Asi mashandisirwo ekushanda kwekuchinja anounzawo mamwe matambudziko.
1. Loop: Zvinoenderana neHuanet switch kero yekudzidza uye chiteshi tafura yekumisikidzwa algorithm, zvishwe hazvitenderwe pakati pekuchinja.Pakangoita loop, iyo inotenderera muti algorithm inofanirwa kutangwa kuvharira chiteshi chinoburitsa loop.Iyo router's routing protocol haina dambudziko iri.Panogona kunge paine nzira dzakawanda pakati pemarouter kuti aenzanise mutoro uye kugadzirisa kuvimbika.
2. Load concentration:Panogona kungova nechiteshi chimwe chete pakati peHuanet switch, kuitira kuti ruzivo ruise pane imwe yekutaurirana link, uye kugovera kwakasimba hakugone kuenzanisa mutoro.Iyo router's routing protocol algorithm inogona kudzivirira izvi.Iyo OSPF routing protocol algorithm haigone chete kugadzira nzira dzakawanda, asi zvakare sarudza nzira dzakasiyana dzakanakisa dzemashandisirwo akasiyana etiweki.
3. Broadcast control:Huanet switches inogona chete kuderedza dhizaini yekunetsana, asi kwete iyo nhepfenyuro dhizaini.Iyo yese switched network inzvimbo yakakura yekutepfenyura, uye mameseji ekutepfenyura akapararira mukati meiyo switched network.Iyo router inogona kutsaura dura renhepfenyuro, uye mapaketi ekutepfenyura haakwanise kuenderera mberi nekutepfenyurwa kuburikidza neiyo router.
