Concept explanation:
Ethernet ndiye njira yolumikizirana yodziwika kwambiri yotengera LAN yomwe ilipo.Netiweki ya Efaneti imagwiritsa ntchito matekinoloje a CSMA/CD (Carrier Sense Multiple Access and Conflict Detection).
Ethernet imayang'anira matekinoloje a LAN:
1. Mtengo wotsika (makadi ochezera a Ethernet osakwana 100);Kutulutsa kwakukulu ndikugwiritsa ntchito kwakukulu kumapangitsa kuti zitheke kutsika mtengo, motero kukhala ndi malo apamwamba pamsika.
2. Ndilo ukadaulo wogwiritsidwa ntchito kwambiri wa LAN;Zimapangitsa kulankhulana Kwabwino;Ntchito yosavuta;Chofunika kwambiri, protocol yabwino kwambiri imapangitsa kulumikizana pakati pa zida zamakompyuta kukhala kosavuta komanso mwachangu.
3. Ndi otsika mtengo kuposa chizindikiro mphete maukonde ndi ATM maukonde;Mtengo ndiwonso chinsinsi cha kupambana kumeneku;Ntchito yosavuta;
4. Maukonde ali ndi liwiro lalikulu: 10Mb / s ~ 10Gb / s.Kukwaniritsa zofunikira za ogwiritsa ntchito pa liwiro la netiweki zosiyanasiyana.
Miyezo iwiri ya Ethernet
DIX EthernetV2: Protocol yoyamba ya LAN product (Ethernet).
IEEE 802.3:Muyezo woyamba wa IEE Ethernet wopangidwa ndi 802.3 Working Group wa IEEE 802 Committee wapanga zosintha zazing'ono pamawonekedwe a chimango.
Chifukwa cha mpikisano wamalonda pakati pa opanga, komiti ya IEEE 802 inakakamizika kupanga mfundo zingapo za LAN: 802.4 token bus network, 802.5 token ring network, etc.
Pofuna kusinthira bwino ulalo wa ulalo wa data ku milingo yosiyanasiyana ya LAN, komiti ya IEEE 802 idagawa ulalo wa ulalo wa data kukhala wosanjikiza womveka wa LLC ndikuwongolera mwayi wolumikizira media MAC sublayer.
LLC ndi MAC zimalumikizidwa ndi netiweki ndi zigawo zakuthupi, motero, zimakhala ndi ntchito zosiyanasiyana.
Mtundu wofotokozera wa LAN wofotokozedwa mu IEEE 802 muyeso umangofanana ndi wosanjikiza wa data wa OSI komanso wosanjikiza wakuthupi.
Zomwe zili pamwambazi ndizofotokozera za Efaneti Ubwino ndi Miyezo yobweretsedwa ndi Shenzhen Haidiwei Optoelectronics Technology Co., Ltd., wopanga zida zolumikizirana zowoneka bwino.Kampani yolumikizirana ndi cpver ONU, OLT, SFP ndi ena ambiri.
