kana iyo OSI referensi modhi, switch inoshanda pachikamu chechipiri chemuenzaniso uyu, data link layer.Sezvinoratidzwa mumufananidzo unotevera, switch ine zviteshi zvisere.Kana mudziyo ukabaiwa muchinja kuburikidza neRJ45, switch's master chip inozoona madoko akabairwa munetwork 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 packet 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, switch inogona kushandiswa kugovera iyo data link layer kutepfenyura, ndiko kuti, iyo dhizaini yekupokana, asi haigone kugovera network layer nhepfenyuro, kureva, nhepfenyuro.
Tanoshandura ane high-bandwidth kumashure bhasi uye mukati matrix matrix.Zvese zviteshi zvekuchinja zvakanamirwa kune iri bhazi rekumashure.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.Iyo switch inogona zvakare "kugovera" network.Iyo switch inongobvumira inodiwa network traffic kuti ipfuure nekuchinja nekuienzanisa neiyo IP kero tafura.Kuburikidza nekusefa uye kutumira kwe switch, iyo dhizaini inogona kudzikiswa kusvika pahukuru hunogoneka.
Izvo zviri pamusoro ndiyo tsananguro yenheyo yekushanda yekushandura inopiwa 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.
