Chii chinonzi router?
Ma router anonyanya kushandiswa muma network emunharaunda uye ma network enzvimbo yakakura. Anogona kubatanidza ma network akawanda kana maseti e network kuti "aturikire" ruzivo rwe data pakati pe network dzakasiyana kana maseti e network, kuitira kuti vagone "kuverenga" data reumwe neumwe kuti vagadzire internet yakakura. Panguva imwe chete, ine mabasa akadai sekutarisira network, kugadzirisa data, uye kubatana kwe network.
Chii chinonzi switch
Zvichitaurwa zviri nyore, switch, inozivikanwawo se switching hub. Musiyano kubva kurouter ndewekuti inogona kubatana kune network yemhando imwe chete, kubatana nemhando dzakasiyana dzenetwork (dzakadai seEthernet neFast Ethernet), uye kuita kuti makombiyuta aya agadzire network.
Inogona kutumira masaini emagetsi uye kupa nzira dzemagetsi dzega dzega kune chero ma network nodes maviri akabatana nayo, nokudaro ichidzivirira kusawirirana kwekutumira uye chiteshi uye ichivandudza kushanda zvakanaka kwebroadband.
Maswichi akajairika anosanganisira maswichi eEthernet, maswichi enetwork yemunzvimbo uye maswichi eWAN, pamwe nemaswichi eoptical fiber uye maswichi ezwi refoni.
Musiyano uripo pakati pe router ne switch:
1. Kubva pamaonero ekushanda, router ine basa rekufonera rinoshanda, iro rinogona kupa IP otomatiki. Makombiyuta akabatana neInternet anogona kushandisa account yeBroadband pane router imwe chete, uye makombiyuta ari munetwork imwe chete yenzvimbo. Panguva imwe chete, inogona kupa masevhisi efirewall. Switch haina masevhisi akadaro uye mabasa, asi inogona kutumira data nekukurumidza kunzvimbo yekuenda kuburikidza neinternal switching matrix, nokudaro ichichengetedza zviwanikwa zvenetwork uye ichivandudza kushanda zvakanaka.
2. Kubva pamaonero echinhu chinotumirwa data, router inosarudza kuti kero yekutumirwa data inoshandisa nhamba yeID yenetwork yakasiyana, uye switch inosarudza kero yekutumirwa data uchishandisa kero yeMAC kana kero chaiyo.
3. Kubva padanho rekushanda, router inoshanda zvichibva paIP addressing uye inoshanda panetwork layer yeOSI model, iyo inogona kubata TCP/IP protocol; switch inoshanda pa relay layer zvichibva paMAC addressing.
4. Kubva pamaonero ekupatsanura, router inogona kupatsanura nzvimbo yekutepfenyura, uye switch inogona kupatsanura nzvimbo yekupokana chete.
5. Kubva pamaonero enzvimbo yekushandisa, ma router anonyanya kushandiswa kubatanidza maLAN nema network ekunze, uye ma switch anonyanya kushandiswa kutumira data mumaLAN.
6. Kubva pamaonero einterface, kune ma router interfaces matatu: AUI port, RJ-45 port, SC port, kune ma switch interfaces akawanda, akadai seConsole port, MGMT interface, RJ45 port, optical fiber interface, auc interface, vty interface uye vlanif Interface, nezvimwewo.
