Chii chinonzi router?
Routers anonyanya kushandiswa munharaunda yenharaunda network uye yakakura nzvimbo network.Inogona kubatanidza ma network akawanda kana masegment etiweki "kushandura" data data pakati pemanetiweki akasiyana kana masegment etiweki, kuitira kuti vagone "kuverenga" data remumwe nemumwe kuti vaumbe Indaneti yakakura.Panguva imwecheteyo, ine mabasa akadai senetiweki manejimendi, kugadzirisa data, uye network yekubatanidza.
Chii chinonzi switch
Zvichitaurwa zviri nyore, switch, inozivikanwawo seyo switching hub.Musiyano kubva kune router ndeyekuti inogona kubatana kune imwechete mhando yetiweki, inobatanidza nemhando dzakasiyana dzemambure (akadai seEthernet uye Fast Ethernet), uye kuita kuti makomputa aya aumbe network.
Inogona kutumira masaini emagetsi uye kupa yakasarudzika nzira dzemagetsi masaini kune chero maviri network node dzakabatana kwairi, nekudaro kudzivirira kutapurirana uye kupokana kwechiteshi nekuvandudza kushanda kweBroadband kushandiswa.
Kuchinja kwakajairika kunosanganisira Ethernet switch, local area network switch uye WAN switch, pamwe neoptical fiber switch uye nharembozha inochinja.
Kusiyana pakati pe router uye switch:
1. Kubva pane imwe nzvimbo yekushanda, router ine virtual dialing function, iyo inogona kugovera IP pakarepo.Makomputa akabatana neInternet anogona kugovera akaundi yebroadband pane imwechete router, uye makomputa ari munharaunda imwechete yenzvimbo network.Panguva imwecheteyo, inogona kupa firewall services.Iyo switch haina masevhisi akadaro uye mabasa, asi inogona kukurumidza kuendesa data kune yekuenda node kuburikidza nemukati switching matrix, nekudaro ichichengetedza network zviwanikwa uye nekuvandudza kugona.
2. Kubva pakuona kwechinhu chekutumira data, router inosarudza kuti kero yekutumira data inoshandisa nhamba yeID yetiweki yakasiyana, uye shanduko inosarudza kero yekutumira data kuburikidza nekushandisa kero yeMAC kana kero yemuviri.
3. Kubva padanho rekushanda, router inoshanda inobva pa IP addressing uye inoshanda pa network network yeOSI model, iyo inogona kubata TCP / IP protocol;switch inoshanda pane relay layer yakavakirwa paMAC addressing.
4. Kubva pakuona kwezvikamu, router inogona kupatsanura nzvimbo yekutepfenyura, uye kushandura kunogona kungoparadzanisa nzvimbo yekupokana.
5. Kubva pakuona kwenzvimbo yekushandiswa, ma routers anonyanya kushandiswa kubatanidza maLAN nekunze kwekunze, uye kushandura kunonyanya kushandiswa kwekutumira data muLANs.
6. Kubva pakuona kwekuona, kune matatu router interfaces: AUI port, RJ-45 port, SC port, kune akawanda switch interfaces, akadai seConsole port, MGMT interface, RJ45 port, optical fiber interface, auc interface, vty interface uye vlanif Interface, nezvimwe.
