Concept tsananguro:
Ethernet ndiyo yakajairika yekutaurirana protocol standard inotorwa neLAN iripo. Iyo Ethernet network inoshandisa CSMA/CD (Carrier Sense Multiple Access uye Conflict Detection) matekinoroji.
Ethernet inotonga LAN matekinoroji:
1. Mutengo wakaderera (pasi pe100 Ethernet network makadhi); Kuburitsa kukuru uye kushandiswa kwakakura kunoita kuti zvikwanise kuwana mutengo wakaderera, nokudaro uchitora chinzvimbo chepamusoro mumusika.
2. Ndiyo inonyanya kushandiswa LAN teknolojia; Inoita Kukurukurirana Kwakanaka; Easy operation; Zvinotonyanya kukosha, iyo yakanakisa protocol inoita kuti kutaurirana pakati pemidziyo yemakomputa kuve nyore uye nekukurumidza.
3. Inodhura kudarika chiratidzo chemhete network uye ATM network; Mutengo ndiwo zvakare kiyi yekubudirira uku; Kushanda kuri nyore;
4. Iyo network ine hupamhi hwekumhanya: 10Mb / s ~ 10Gb / s. Sangana nezvido zvevashandisi zvekumhanya kwakasiyana kwetiweki.
Maviri Ethernet zviyero
DIX EthernetV2: Yekutanga LAN chigadzirwa (Ethernet) protocol.
IEEE 802.3:Yekutanga IEE Ethernet mwero wakagadzirwa ne802.3 Working Group yeIEEE 802 Committee yakaita shanduko diki mufomati yefomati.
Nekuda kwemakwikwi ekutengeserana pakati pevagadziri, IEEE 802 komiti yakamanikidzwa kugadzira akati wandei akasiyana LAN zviyero: 802.4 token bhazi network, 802.5 token ring network, nezvimwe.
Kuti ugadzirise zvirinani iyo data link layer kune akasiyana LAN zviyero, IEEE 802 komiti yakakamura iyo data link layer kuita inonzwisisika link layer LLC sublayer uye midhiya yekuwana control MAC sublayer.
LLC neMAC zvakabatana kunetiweki uye zvidimbu zvemuviri, zvichiteerana, saka zvine mabasa akasiyana.
Iyo LAN referensi modhi inotsanangurwa muIEEE 802 yakajairwa inongoenderana neOSI referensi modhi ye data link layer uye yemuviri layer.
Iri pamusoro ndiyo tsananguro yeruzivo yeEthernet Advantages uye Mayero yakaunzwa naShenzhen Haidiwei Optoelectronics Technology Co., Ltd., mugadziri wemidziyo yekukurukurirana yemaziso. Iyo yekutaurirana zvigadzirwa kambani cpverONU, OLT, SFP uye zvimwe zvakawanda.
