    ʻO nā pono a me nā kūlana o Ethernet

    Ka manawa hoʻouna: Oct-12-2022

    Wehewehe manaʻo:

    ʻO Ethernet ka maʻamau maʻamau kamaʻilio protocol maʻamau i hāpai ʻia e ka LAN e kū nei. Hoʻohana ka pūnaewele Ethernet i nā ʻenehana CSMA/CD (Carrier Sense Multiple Access and Conflict Detection).

    ʻO Ethernet ka luna o nā ʻenehana LAN:

    1. Ke kumu kūʻai haʻahaʻa (emi iho ma mua o 100 mau kāleka pūnaewele Ethernet); ʻO ka hoʻopuka nui a me ka hoʻohana ākea e hiki ai ke hoʻokō i kahi kumukūʻai haʻahaʻa, no laila e noho ana i kahi kūlana koʻikoʻi ma ka mākeke.

    2. ʻO ia ka ʻenehana LAN i hoʻohana nui ʻia; Hana ia i ka launa kamaʻilio; Hana maʻalahi; ʻO ka mea nui aku, ʻo ka protocol maikaʻi loa e maʻalahi a wikiwiki hoʻi ka kamaʻilio ma waena o nā polokalamu kamepiula.

    3. ʻOi aku ka maikaʻi ma mua o ka pūnaewele hōʻailona hōʻailona a me ka pūnaewele ATM; ʻO ke kumukūʻai hoʻi ke kī i kēia holomua; Hana maʻalahi;

    4. He laulā ka wikiwiki o ka pūnaewele: 10Mb / s ~ 10Gb / s. Hoʻokō i nā koi o nā mea hoʻohana no nā wikiwiki pūnaewele like ʻole.

    ʻElua mau kūlana Ethernet

    DIX EthernetV2: ʻO ka protocol LAN mua (Ethernet).

    IEEE 802.3:ʻO ka maʻamau IEE Ethernet mua i hoʻomohala ʻia e ka 802.3 Working Group o IEEE 802 Committee ua hoʻololi liʻiliʻi i ke ʻano kiʻi.

    Ma muli o ka hoʻokūkū pāʻoihana ma waena o nā mea hana, ua koi ʻia ke komite IEEE 802 e hoʻokumu i nā kūlana LAN like ʻole: 802.4 token bus network, 802.5 token ring network, etc.

    I mea e hoʻololi maikaʻi ai i ka papa loulou ʻikepili i nā kūlana LAN like ʻole, ua hoʻokaʻawale ke kōmike IEEE 802 i ka papa loulou ʻikepili i loko o ka logical link layer LLC sublayer a me ka media access control MAC sublayer.

    Hoʻopili ʻia ʻo LLC a me MAC i ka pūnaewele a me nā papa kino, kēlā me kēia, no laila he mau hana like ʻole lākou.

    ʻO ke kumu hoʻohālike LAN i wehewehe ʻia ma ka maʻamau IEEE 802 pili wale i ka papa loulou ʻikepili a me ka papa kino o ka OSI.

    ʻO ka mea i luna nei ka wehewehe ʻike o Ethernet Advantages and Standards i lawe ʻia e Shenzhen Haidiwei Optoelectronics Technology Co., Ltd., kahi mea hana o nā lako kamaʻilio optical. ʻO ka hui huahana kamaʻilio cpverONU, OLT, SFP a me nā mea hou aku.

    ʻO nā pono a me nā kūlana o Ethernet
