Umuyoboro waho (LAN)
Yerekeza ku itsinda rya mudasobwa rigizwe na mudasobwa nyinshi zahujwe mu gace runaka. Mubisanzwe, iri muri metero ibihumbi bike z'umurambararo. LAN irashobora kumenya gucunga dosiye, kugabana porogaramu, gucapa
Ibiranga harimo kugabana imashini, guteganya mumatsinda yakazi, imeri na serivisi zitumanaho fax, nibindi byinshi. Umuyoboro waho wafunzwe kandi urashobora kuba ugizwe na mudasobwa ebyiri mubiro.
Irashobora kuba igizwe na mudasobwa ibihumbi n'ibihumbi muri sosiyete.
Umuyoboro mugari (WAN)
Ni ikusanyirizo ry'imiyoboro ya mudasobwa ikora ahantu hanini, mu karere. Mubisanzwe hirya no hino mu ntara, imigi, cyangwa igihugu. Umuyoboro mugari urimo subnets zingana. Subnets irashobora
Irashobora kuba umuyoboro waho cyangwa umuyoboro mugari muto.
Itandukaniro hagati yumurongo waho hamwe numuyoboro mugari
Umuyoboro waho waho uri mukarere runaka, mugihe umuyoboro mugari uhuza umwanya munini. Nigute dushobora gusobanura kariya gace? Kurugero, icyicaro gikuru cyisosiyete nini giherereye i Beijing.
Pekin, n'amashami akwirakwira mu gihugu hose. Niba isosiyete ihuza amashami yose hamwe binyuze murusobe, noneho ishami ni urusobe rwakarere, hamwe nicyicaro gikuru
Urusobe rwisosiyete numuyoboro mugari.
Ni irihe tandukaniro riri hagati yicyambu cya WAN nicyambu cya LAN ya router?
Uyu munsi mugari wa Broadband router mubyukuri ni imiterere ihuriweho na routing + switch. Turashobora kubitekereza nkibikoresho bibiri.
WAN: Yifashishijwe muguhuza aderesi ya IP yo hanze, mubisanzwe yerekeza kuri egress, no kohereza IP data paki kuva imbere imbere ya LAN.
LAN: Yifashishijwe guhuza aderesi ya IP imbere. Imbere muri LAN ni switch. Ntidushobora guhuza icyambu cya WAN no gukoreshaRouternkibisanzwehindura.
Umuyoboro utagira umuyaga (WLAN)
WLAN ikoresha amashanyarazi ya electronique kugirango yohereze kandi yakire amakuru hejuru yikirere idakeneye itangazamakuru rya kabili. Igipimo cyo kohereza amakuru ya WLAN irashobora kugera kuri 11Mbps, kandi intera yoherejwe ni
Nibirometero birenga 20 km. Nubundi buryo cyangwa kwagura imiyoboro gakondo, insinga ya LAN ibohora abantu kumeza kandi ibemerera gukora umwanya uwariwo wose
Kugera amakuru aho ariho hose biteza imbere abakozi neza.
WLAN ivugana ikoresheje itsinda rya radiyo ISM (Inganda, Ubumenyi, Ubuvuzi). Igipimo cya 802.11a kuri WLAN ikoresha umurongo wa 5 GHz kandi igashyigikira cyane
Umuvuduko ntarengwa ni 54 Mbps, mugihe 802.11b na 802.11g zisanzwe zikoresha umurongo wa 2.4 GHz kandi zishyigikira umuvuduko wa 11 Mbps na 54 Mbps.
None WIFI dusanzwe dukoresha ni iki?
WIFI ni protocole yo gushyira mubikorwa imiyoboro idafite insinga (mubyukuri protocole yo guhana intoki), naho WIFI nibisanzwe kuri WLAN. Umuyoboro wa WIFI ukora muri bande ya 2.4G cyangwa 5G. Ibindi
Hanze ya 3G / 4G nayo ni umuyoboro udafite umugozi, ariko protocole iratandukanye kandi igiciro ni kinini cyane!
Umuyoboro Wibanze Wibanze (VLAN)
Virtual LAN (VLAN) bivuga ikoranabuhanga ryurusobe rwemerera imbuga murusobekerane kugabanywa mubice bitandukanye byumvikana ukurikije ibikenewe, utitaye kumwanya wabo.
Kurugero, abakoresha kumagorofa atandukanye cyangwa mumashami atandukanye barashobora kwinjiza LAN zitandukanye nkuko bikenewe: igorofa ya mbere igabanijwemo igice cya 10.221.1.0, naho igorofa ya kabiri igabanyijemo
10.221.2.0 igice cyurusobe, nibindi
