Incazelo yomqondo:
I-Ethernet iyindinganiso evamile yokuxhumana esetshenziswa yi-LAN ekhona.Inethiwekhi ye-Ethernet isebenzisa ubuchwepheshe be-CSMA/CD (Carrier Sense Multiple Access and Conflict Detection) .
I-Ethernet ibusa ubuchwepheshe be-LAN:
1. Izindleko eziphansi (amakhadi enethiwekhi e-Ethernet angaphansi kwe-100);Umkhiqizo omkhulu kanye nokusetshenziswa okubanzi kwenza kube nokwenzeka ukuzuza intengo ephansi, ngaleyo ndlela kube nesikhundla esiphezulu emakethe.
2. Iwubuchwepheshe be-LAN obusetshenziswa kakhulu;Kwenza ukuxhumana Kalula;Ukusebenza okulula;Okubaluleke nakakhulu, iphrothokholi enhle kakhulu yenza ukuxhumana phakathi kwamadivaysi ekhompyutha kube lula futhi kusheshe.
3. Kushibhile kunenethiwekhi yendandatho yamathokheni kanye nenethiwekhi ye-ATM;Izindleko nazo ziyisihluthulelo sale mpumelelo;Ukusebenza okulula;
4. Inethiwekhi inebanga elibanzi lesivinini: 10Mb/s~10Gb/s.Hlangana nezidingo zabasebenzisi ngesivinini esihlukile senethiwekhi.
Izindinganiso ezimbili ze-Ethernet
I-DIX EthernetV2: Iphrothokholi yokuqala yomkhiqizo we-LAN (Ethernet).
IEEE 802.3:Izinga lokuqala le-IEE Ethernet elithuthukiswe yiQembu Elisebenzayo le-802.3 leKomidi le-IEEE 802 lenze izinguquko ezincane kufomethi yozimele.
Ngenxa yomncintiswano wezohwebo phakathi kwabakhiqizi, ikomidi le-IEEE 802 laphoqeleka ukuthi lenze amazinga amaningana e-LAN ahlukene: inethiwekhi yebhasi yamathokheni angu-802.4, inethiwekhi yendandatho yamathokheni angu-802.5, njll.
Ukuze kulungiswe kangcono isendlalelo sesixhumanisi sedatha kumazinga ahlukahlukene e-LAN, ikomidi le-IEEE 802 lahlukanisa isendlalelo sesixhumanisi sedatha sibe isendlalelo esingaphansi esinengqondo se-LLC nesilawulayo sokufinyelela kwemidiya i-MAC sublayer.
I-LLC ne-MAC zixhunywe kunethiwekhi nezendlalelo zomzimba, ngokulandelana, ngakho zinemisebenzi ehlukene.
Imodeli yesithenjwa ye-LAN echazwe kuzinga le-IEEE 802 ihambisana kuphela nosendlalelo sesixhumanisi sedatha yemodeli yereferensi ye-OSI kanye nesendlalelo esibonakalayo.
Okungenhla yincazelo yolwazi ye-Ethernet Advantages and Standards elethwa u-Shenzhen Haidiwei Optoelectronics Technology Co., Ltd., umkhiqizi wemishini yokuxhumana ebonakalayo.Inkampani yemikhiqizo yezokuxhumana cpver ONU, OLT, SFP nokunye okuningi.
