kana iyo OSI referensi modhi, iyochinjainoshanda pachikamu chechipiri chemuenzaniso uyu, iyo data link layer. Sezvinoratidzwa mumufananidzo unotevera, thechinjaine zviteshi zvisere. Kana mudziyo ukabaiwa muchinjakuburikidza neRJ45, iyo switch's master chip ichaona madoko akabairwa mune network tambo, uye kubatana kunobudirira. Iyo mac kero yechishandiso chakabatana ndeye-kune-imwe inoenderana nechiteshi. Kana ese masere madoko akaiswa mukati, iyo yemukati tenzi inogona kugadzira MAC tafura ine ese madoko. Mune inotevera chiteshi kutaurirana, kana mudziyo uchitumira ruzivo, unoburitsa data pakiti ine sosi mac uye chinangwa mac. Mushure mekunge data packet yasvika kune master control, inogona kukurumidza kutumira iyo data packet kune mudziyo ine inoenderana mac kero kuburikidza neyakasimbiswa mac tafura, kuitira kuti uwane kutaurirana pakati pemidziyo. Pamusoro pezvo, mapaketi anotumirwa kukero yeMAC anongotumirwa kumachiteshi anoenderana, kwete ese madoko. Naizvozvo, thechinjainogona kushandiswa kupatsanura data link layer kutepfenyura, kureva kuti, iyo dhizaini yekupokana, asi haigone kupatsanura network layer nhepfenyuro, kureva, nhepfenyuro.
The chinjaine high-bandwidth kumashure bhazi uye mukati matrix inoshandura. Zvose zviteshi zvechinjaakabatanidzwa nebhazi rekumashure iri. Mushure mekunge dunhu rekutonga ragamuchira pakiti yedata, chiteshi chekugadzira chinotarisa kumusoro tafura yekufananidza kero mundangariro kuti uone kuti ndeipi port NIC (network kadhi) yekuenda MAC (hardware kero yetiweki kadhi) yakanamatira. Iyo data packet ichakurumidza kuendeswa kune yekuenda chiteshi kuburikidza neyemukati yekutsinhana matrix. Kana iyo MAC yekuenda isipo, ichatepfenyurwa kune ese zviteshi, Mushure mekugamuchira mhinduro yechiteshi, shanduko "ichadzidza" iyo MAC kero nyowani uye kuiwedzera kune yemukati MAC kero tafura. Thechinjainogona zvakare "chikamu" network. Thechinjainongobvumira inodiwa network traffic kuti ipfuure nepakatichinjanekuienzanisa neiyo IP kero tafura. Kuburikidza nekusefa uye kutumira kwe switch, iyo dhizaini inogona kudzikiswa kusvika pakukura kunogoneka.
Izvo zviri pamusoro ndiyo tsananguro yenheyo yekushanda yechinjazvinopihwa neShenzhen HDV Phoelectron Technology Co., Ltd. Ndinovimba chinyorwa ichi chinogona kukubatsira iwe kuwedzera ruzivo rwako. Kunze kwechinyorwa ichi kana iwe uchitsvaga yakanaka optical fiber yekutaurirana michina yekugadzira kambani yaungafunganezvedu.
