Efaneti lophimba ndi mtundu wa lophimba kuti transmits deta zochokera Efaneti, ndi Efaneti ndi njira kugawana mabasi kufala TV.Kapangidwe ka chosinthira cha Efaneti: doko lililonse la chosinthira cha Efaneti limalumikizidwa mwachindunji ndi wolandila, ndipo nthawi zambiri amakhala mumayendedwe athunthu.Kusinthaku kungathenso kugwirizanitsa ma doko angapo nthawi imodzi, kotero kuti gulu lirilonse la makamu omwe amalankhulana akhoza kufalitsa deta popanda mikangano.Kusintha kwa Ethernet ndiyenso ntchito yotchuka kwambiri, ndipo mtengo wake ndi wotsika mtengo.Chifukwa chake, gawo logwiritsira ntchito ndi lalikulu kwambiri, ndipo ma switch a Efaneti amatha kuwoneka mu ma LAN akulu ndi ang'onoang'ono.Kusintha kwa Ethernet nthawi zambiri kumakhala ndi madoko angapo mpaka angapo.M'malo mwake, ndi mlatho wamadoko ambiri.Kuonjezera apo, mlingo wake wa doko ukhoza kukhala wosiyana, ndipo mawonekedwe ake ogwira ntchito angakhalenso osiyana, monga kupereka 10M ndi 100M bandwidth, kupereka theka-duplex, full-duplex, ndi modes adaptive work modes.Mfundo ya Ethernet switch: Ethernet switch ndi makina omwe ali pa data link layer.Ethernet imagwiritsa ntchito ma adilesi (adilesi ya MAC), 48 bits, ndi 6 byte.Mfundo yake yogwirira ntchito ndi yakuti pamene chimango chowulutsa chikalandiridwa, chidzatumiza ku madoko onse kupatula doko lolandira.Chimango cha unicast chikalandiridwa, yang'anani adilesi yomwe ikupita ndikugwirizana ndi tebulo la adilesi ya MAC.Ngati pali adilesi yopitira, itumizidwa.Ngati palibe, idzasefukira (kuwulutsa).Pambuyo pa kuwulutsa, ngati palibe wolandira amene adilesi yake ya MAC ili yofanana ndi adilesi ya MAC ya chimango, idzatayidwa.Ngati pali wolandila yemwe adilesi ya MAC ili yofanana, idzawonjezedwa patebulo lake la adilesi ya MAC.
