    Mfundo Yogwira Ntchito ya Switch

    Nthawi yotumiza: Sep-15-2022

    kapena chitsanzo cha OSI, thekusinthaimagwira ntchito pagawo lachiwiri lachitsanzo ichi, data link layer. Monga tawonetsera mu chithunzi chotsatirachi, akusinthaali ndi madoko asanu ndi atatu. Pamene chipangizo cholumikizidwa mukusinthakudzera pa RJ45, chip master's switch's master chip chizindikiritsa madoko omwe alumikizidwa mu chingwe cha netiweki, ndipo kulumikizanako kukuyenda bwino. Adilesi ya Mac ya chipangizo cholumikizidwa ndi chimodzi ndi chimodzi chogwirizana ndi doko. Madoko onse asanu ndi atatu akalumikizidwa, mbuye wamkati amatha kupanga tebulo la MAC ndi madoko onse. Mukulankhulana kwadoko kotsatira, chipangizocho chikatumiza chidziwitso, chidzatulutsa paketi ya data yokhala ndi ma source Mac ndi chandamale Mac. Pambuyo paketi ya data ikafika pa master control, imatha kutumiza phukusi la data ku chipangizocho ndi adilesi yofananira ya mac kudzera pa tebulo lokhazikitsidwa la mac, kuti mukwaniritse kulumikizana pakati pa zida. Kuphatikiza apo, mapaketi otumizidwa ku adilesi ya MAC amangotumizidwa kumadoko awo ogwirizana, osati madoko onse. Chifukwa chake, akusinthaangagwiritsidwe ntchito kugawa ulalo wosanjikiza wosanjikiza kuwulutsa, ndiko kuti, ankalamulira mikangano, koma sangathe kugawa maukonde wosanjikiza kuwulutsa, ndiye ankalamulira kuwulutsa.

    The kusinthaali ndi mabasi obwerera kumbuyo komanso matrix osinthira mkati. Madoko onse akusinthaalumikizidwa ku basi yakumbuyo iyi. Gawo lowongolera litalandira paketi ya data, doko lokonzekera lidzayang'ana tebulo lofananiza la adilesi mu kukumbukira kuti lidziwe kuti NIC (network card) yopita MAC (hardware adilesi ya network card) yalumikizidwa. Phukusi la data litumizidwa mwachangu ku doko lomwe likupita kudzera mu matrix osinthira mkati. Ngati MAC yopita kulibe, idzafalitsidwa ku madoko onse, Pambuyo polandira yankho la doko, kusinthanitsa "kudzaphunzira" adiresi yatsopano ya MAC ndikuwonjezera pa tebulo lamkati la MAC. Thekusinthaingathenso "kugawa" maukonde. Thekusinthazimangolola magalimoto ofunikira pa intaneti kudutsakusinthapoyerekezera ndi tebulo la adilesi ya IP. Kupyolera mu kusefa ndi kutumiza kwa switch, dera la mikangano litha kuchepetsedwa mpaka kukula kotheka.

    Pamwambapa ndi kufotokoza kwa mfundo ntchito yakusinthazoperekedwa ndiMalingaliro a kampani Shenzhen HDV Phoelectron Technology Co., Ltd. ndikukhulupirira kuti nkhaniyi ingakuthandizeni kukulitsa chidziwitso chanu. Kupatula nkhaniyi ngati mukuyang'ana kampani yabwino yopanga zida zoyankhulirana zama fiber zomwe mungaganizirezambiri zaife.
