Inkcazo yengcamango:
I-Ethernet ngowona mgangatho uqhelekileyo wonxibelelwano weprotocol owamkelwa yiLAN ekhoyo. Inethiwekhi ye-Ethernet isebenzisa i-CSMA / CD (i-Carrier Sense Access Multiple Access kunye ne-Conflict Detection) ubuchwepheshe.
I-Ethernet ilawula itekhnoloji ye-LAN:
1. Ixabiso eliphantsi (ngaphantsi kwe-100 amakhadi enethiwekhi ye-Ethernet); Imveliso enkulu kunye nokusetyenziswa okubanzi kwenza kube lula ukufikelela kwixabiso eliphantsi, ngaloo ndlela ibambe indawo ephezulu kwimarike.
2. Yeyona teknoloji yeLAN isetyenziswa kakhulu; Yenza unxibelelwano olulula; Ukusebenza ngokulula; Okubaluleke ngakumbi, iprotocol ebalaseleyo yenza unxibelelwano phakathi kwezixhobo zekhompyuter lube lula kwaye lukhawuleze.
3. Ixabiso eliphantsi kunenethiwekhi ye-token ring kunye nenethiwekhi ye-ATM; Iindleko zikwasisitshixo kule mpumelelo; Ukusebenza okulula;
4. Inethiwekhi inoluhlu olubanzi lwesantya: 10Mb / s ~ 10Gb / s. Zifezekise iimfuno zabasebenzisi kwizantya zenethiwekhi ezahlukeneyo.
Imigangatho emibini ye-Ethernet
I-DIX EthernetV2: Iprotocol yokuqala ye-LAN yemveliso (Ethernet).
IEEE 802.3:Umgangatho wokuqala we-IEE Ethernet ophuhliswe yiQela eliSebenzayo le-802.3 leKomiti ye-IEEE 802 lenze utshintsho oluncinci kwifomathi yesakhelo.
Ngenxa yokhuphiswano lwezorhwebo phakathi kwabavelisi, ikomiti ye-IEEE 802 yaphoqeleka ukuba iqulunqe imigangatho eyahlukeneyo ye-LAN: i-802.4 inethiwekhi yebhasi ye-token, i-802.5 i-token network ring network, njl.
Ukuze ulungelelanise ngcono umaleko wekhonkco lwedatha kwimigangatho eyahlukeneyo ye-LAN, ikomiti ye-IEEE 802 yahlulahlula umaleko wekhonkco ledatha kwi-logical link layer LLC kunye ne-media access control ye-MAC sublayer.
I-LLC kunye ne-MAC ziqhagamshelwe kwinethiwekhi kunye neengqimba zomzimba, ngokulandelanayo, ngoko banemisebenzi eyahlukeneyo.
Imodeli yereferensi ye-LAN echazwe kumgangatho we-IEEE 802 ihambelana kuphela nemodeli ye-OSI yereferensi yedatha yedatha kunye nomgangatho womzimba.
Oku ngasentla yingcaciso yolwazi lwe-Ethernet Advantages kunye neMigangatho eziswa nguShenzhen Haidiwei Optoelectronics Technology Co., Ltd., umenzi wezixhobo zonxibelelwano zokukhanya. Inkampani yeemveliso zonxibelelwano cpverI-ONU, OLT, SFP kunye nezinye ezininzi.
