Cov ntsiab lus piav qhia:
Ethernet yog tus qauv kev sib txuas lus ntau tshaj plaws uas tau txais los ntawm LAN uas twb muaj lawm.Ethernet network siv CSMA/CD (Carrier Sense Multiple Access and Conflict Detection) technologies.
Ethernet dominates LAN technologies:
1. Tus nqi qis (tsawg dua 100 Ethernet network cards);Cov zis loj thiab siv dav ua rau nws ua tau kom ua tiav tus nqi qis, yog li tuav txoj haujlwm tseem ceeb hauv kev ua lag luam.
2. Nws yog cov cuab yeej siv LAN tshaj plaws;Nws ua rau kev sib txuas lus yooj yim;Kev ua haujlwm yooj yim;Qhov tseem ceeb tshaj, cov txheej txheem zoo heev ua rau kev sib txuas lus ntawm cov cuab yeej siv computer yooj yim dua thiab sai dua.
3. Nws yog pheej yig dua token nplhaib network thiab ATM network;Tus nqi kuj yog tus yuam sij rau txoj kev vam meej no;Kev ua haujlwm yooj yim;
4. Lub network muaj ntau yam ceev: 10Mb/s ~ 10Gb/s.Ua tau raws li cov neeg siv khoom xav tau rau kev sib txawv network ceev.
Ob tus qauv Ethernet
DIX EthernetV2: Thawj LAN khoom (Ethernet) raws tu qauv.
IEEE 802.3:Thawj IEE Ethernet tus qauv tsim los ntawm 802.3 Pawg Neeg Ua Haujlwm ntawm IEEE 802 Pawg Neeg Ua Haujlwm tau hloov pauv me me hauv cov qauv qauv.
Vim tias muaj kev sib tw ua lag luam ntawm cov tuam txhab tsim khoom, IEEE 802 pawg neeg raug yuam kom tsim ntau yam qauv LAN: 802.4 token tsheb npav network, 802.5 token nplhaib network, thiab lwm yam.
Txhawm rau kom hloov kho cov ntaub ntawv txuas tau zoo dua rau ntau cov qauv LAN, IEEE 802 pawg neeg muab faib cov ntaub ntawv txuas txheej rau hauv cov txheej txheem txuas LLC sublayer thiab media access control MAC sublayer.
LLC thiab MAC txuas nrog lub network thiab cov txheej txheem lub cev, feem, yog li lawv muaj cov haujlwm sib txawv.
Tus qauv siv LAN tau piav qhia hauv IEEE 802 tus qauv tsuas yog sib haum rau OSI cov qauv siv cov ntaub ntawv txuas txheej thiab txheej lub cev.
Cov saum toj no yog cov lus piav qhia ntawm Ethernet Qhov Zoo thiab Cov Qauv coj los ntawm Shenzhen Haidiwei Optoelectronics Technology Co., Ltd., lub chaw tsim khoom ntawm cov khoom siv kho qhov muag.Cov khoom lag luam sib txuas lus cpver ONU, OLT, SFP thiab ntau ntxiv.
