UMURONGO ni iki?
LAN bisobanura Umuyoboro waho.
LAN ihagarariye indangarubuga, bivuze ko abanyamuryango bose ba LAN bazakira paki zoherejwe numunyamuryango uwo ari we wese.Abagize LAN barashobora kuvugana kandi barashobora gushiraho inzira zabo kuri mudasobwa kuva kubakoresha batandukanye kugirango bavugane batanyuze kuri enterineti.
1) Imiterere yibanze ya LAN
Nkuko bigaragara ku gishushanyo kiri hejuru, nuburyo bwibanze bwa LAN.Niba hari ibikoresho bitandukanye, ugomba kubona aderesi ya MCA yundi.
Urugero rurambuye: A yohereza amakuru kuri C, ariko A ntabwo izi adresse ya MAC ya C. Muri iki gihe, binyuze muri protocole ya ARP (Adresse Resolution Protocol;) Kugirango ubone adresse ya MAC ya C, Banza itangaza icyifuzo cya ARP gikubiyemo intego ya aderesi ya IP kubikoresho byose bifitanye isano na hub.Nyuma yo kwakira ibiganiro, C asubiza aderesi ya MAC kuri A, nibindi bikoresho birukana amakuru.Kugeza ubu, hashyizweho uburyo bwo gutegura itumanaho hagati yibikoresho.Inzira yavuzwe haruguru irashobora koroshya ibi bikurikira: A - protocole ya ARP: ikemura adresse ya MAC yintego IP - C izasubiza adresse ya MAC kuri
Ibikoresho bihujwe muri hub biri murwego rumwe rwamakimbirane no kumurongo wo gutangaza.Kuberako hariho inzira imwe gusa, indangarugero yamakimbirane ni indangarubuga.Gusobanukirwa byoroshye kuriyi miterere nuko igikoresho kimwe gusa gishobora kohereza ikimenyetso icyarimwe nibindi bikoresho bishobora kwakira ibimenyetso.
2) Hub nigikoresho cyumubiri gifatika, ni ukuvuga urwego rwa mbere rwa OSI.Ikoreshwa cyane cyane kwakira, kugarura, kwagura, no kohereza ibimenyetso.Iyo impinduramatwara ihindagurika hamwe na fibre optique ikoreshwa mugukwirakwiza ibimenyetso, hamwe no kwiyongera kwintera, ibimenyetso bizacika intege bigatera kugoreka.Kugoreka ibimenyetso bizatera amakuru yoherejwe kutamenyekana, kandi amaherezo bizana guhagarika ibimenyetso.Hifashishijwe hub, ibimenyetso birashobora kugenda kure;Mugihe kimwe, hub ifite intera nyinshi, zishobora kwagura umubare wanyuma hamwe nubunini bwa LAN.
Ikibazo: Ibikoresho byose kuri hub imwe igabana umurongo.Niba umubare wibikoresho ari munini cyane, bizatera guhuza umurongo, kandi mubihe bikomeye, umuyaga mwinshi.
Iterambere: Urwego runini rwamakimbirane rushobora kugabanywa mubice byinshi bito byamakimbirane ukoresheje switch, bishobora kugabanya urugero rwamakimbirane no kugabanya amakuru.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa ONU LAN yazanwe na Shenzhen HDV Phoelectron Technology Co., Ltd. Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. ni uruganda ruzobereye muri optiqueibikoresho by'itumanaho.
