Chiratidzo Ring Ring Networks Ndiyo LAN Technology
Yakagadzirwa neBM munguva ye1980 seimwe nzira yeEthernet , Token Ring iyo inoshandiswa ne data data teknolojia yemunzvimbo dzenharaunda dzenharaunda (LANs) apo zvigadzirwa zvinobatanidzwa munyeredzi kana rongedzo rwechikwereti. Iyo inoshanda pakasara 2 yemuenzaniso weOSI .
Kutanga mumakore ekuma1990, Chiratidzo Chinoderera zvakanyanya pakuzivikanwa uye zvishoma nezvishoma chakabudiswa mumabhizinesi mashandisirwo sezvo teknolojia yeEthernet yakatanga kutonga LAN mazano.
Dhigirii yeChechi yeChirungu inobatsira chete kusvika 16 Mbps . Mumakore ekuma1990, shanduro yebazi yakadanwa neHigh Speed Token Ring (HSTR) yakagadziridza teknolojia yekuwedzera Token Ring kusvika 100 Mbps kukwikwidzana neEthernet, asi kushaya kukwana mumusika kwaive kune zveHSTR michina uye teknolojia yakasiyiwa.
Iko Chiratidzo Chigoni Chinoshanda
Kusiyana nedzimwe mimwe miitiro yeLAN inopindirana, Token Ring inogadzira imwe kana kupfuura yakawanda mafaira ekufambisa anoramba achipararira kuburikidza nemutambo.
Mafaira aya anogoverwa nezvose zvakagadzirirwa zvishandiso pamutambo sezvinotevera:
- Chirongwa ( packet ) chinosvika pane imwe inotevera muchengeti wekutevedzera.
- Icho chigadziri chinoongorora kana chitubu chacho chine shoko rakanyorerwa kwariri. Kana zvakadaro, chigadzirwa chacho chinobvisa mharidzo kubva pa-frame. Kana zvisingaiti, chimiro chacho hachina chinhu (chinonzi chimiro chechiratidzo ).
- Chigadziri chinobata faira chinosarudza kana kutumira mharidzo. Kana zvakadaro, inoshandisa dhiyabhorosi yedhipatimendi muhomwe yetikwangwani uye inoidzosera kuLAN. Kana zvisingaiti, chigadzirwa chacho chinodzinga fomu yetikiti yechina inotevera pakutevedzera.
Mune mamwe mazwi, mukuedza kuderedza mitambo yekubatana, imwe chete yedhiyo inoshandiswa panguva. Matanho aya ari pamusoro apa anoramba achidzokororwa kwezviridzwa zvose muchitinho chechiratidzo.
Zviratidzo zviratidzo zvitatu zvinosanganisira kutanga uye kuguma zvinogadzirisa izvo zvinorondedzera kutanga nekuguma kwegadziro (kureva kuti vanocherechedza miganhu yefaira). Uyewo mukati mechiratidzo chiratidzo chekuwana nekuwana. Iyo yakareba urefu hwe data inenge ye 4500 bytes.
Iko Chiratidzo Ring Chienzaniswa neEthernet
Kusiyana netsamba yeEthernet, zvigadziri mukati meToken Ring network zvinogona kunge zvakanyatsofanana neAAC address pasina kukonzera nyaya.
Heano mamwe maonero akasiyana:
- Kubhabhatidza kweChiratidzo Chikwata chendaneti zvinodhura kupfuura Ethernet's CAT 3 / 5e. Uyezve mari yakawanda inonzi Token Ring network makadhi uye mapeji.
- Chiratidzo Chigadziko chinogona kugadziridzwa apo dzimwe node dzinogona kuva nepamusoro pepamusoro pane dzimwe, chimwe chinhu chisingabvumirwi neEthernet isina kuchena.
- Sezvakataurwa pamusoro apa, Token Ring network dzinoshandisa zviratidzo kuti dzisaita kupopotedzana, nepo nhare dzeEthernet (kunyanya kana hubs dzinoshandiswa) dzinowanzova nyore. Ichi ndicho chikonzero nhare dzeEthernet dzinoshandisa kushanduka.
