Hub muab faib los ntawm cheeb tsam hauv cheeb tsam network

Los ntawm qhov kev xav ntawm cov cheeb tsam hauv cheeb tsam, hubs tuaj yeem muab faib ua tsib hom sib txawv.
(1) Ib leeg relay network ntu hub
Qhov yooj yim hub yog ib hom hub siv rau qhov yooj yim relay LAN network ntu, zoo ib yam li stacked Ethernet hubs lossis Token Ring Multi Station Access Units (MAUs).
(2) Ntau ntu hub
Tau txais ncaj qha los ntawm ib qho kev sib txuas lus sib txuas ib ntu hub, siv lub hub backplane, hom hub no muaj ntau qhov sib txuas sib txuas. Nws lub ntsiab kom zoo dua yog tias cov neeg siv tuaj yeem faib thoob plaws ntau qhov kev sib txuas hauv network kom txo tau cov ntaub ntawv tsheb thauj mus los ntawm txhua ntu ntu. Cov ntaub ntawv kev khiav tsheb ntawm cov ntu feem ntau yuav tsum muaj kev ywj pheej txuas hniav lossis routers.
(3) Chaw nres nkoj hloov hub
Lub integrator no yog ib lub hub uas automates cov txheej txheem kev twb kev txuas ntawm cov neeg siv ports thiab ntau backplane network segments raws li ib tug ntau segment hub, thiab yog siv los ntawm kev ntxiv ib tug Port Switching Matrix (PSM). PSM tuaj yeem muab cov cuab yeej siv hluav taws xob sib txuas rau lwm tus neeg siv qhov chaw nres nkoj mus rau ib qho kev sib txuas ntawm lub cev ntawm lub hub backplane. Lub ntsiab kom zoo dua ntawm qhov chaw nres nkoj switched hubs yog lub automation feature ntawm kev txav mus los, ntxiv, thiab hloov kho.
(4) Network interconnection hub
Chaw nres nkoj switching hubs tsom rau kev hloov chaw nres nkoj, thaum lub network interconnection hubs tuaj yeem muab qee hom kev sib txuas ntawm ntau qhov sib txuas ntawm lub nraub qaum, uas tau ua tiav los ntawm kev sib txuas lus, router, lossis LAN hloov. Hom hub no feem ntau yog nyob rau hauv daim ntawv ntawm lub chassis.
(5) Hloov hub
Lub ciam teb ntawm hubs thiab keyboards tau dhau los ua qhov muag plooj. Lub hub switching muaj ib tug core switching backplane uas siv ib tug ntshiab switching system es tsis txhob ntawm tsoos sib koom xov xwm relay network segments. Cov khoom lag luam no twb tau tsim tawm lawm, thiab hybrid (relay / hloov) hubs zoo li yuav ua tus thawj coj lag luam hauv xyoo tom ntej. Nws yuav tsum tau muab sau tseg tias yuav luag tsis muaj qhov sib txawv ntawm cov yam ntxwv ntawm xws li hubs thiab keyboards.
Nrog rau txoj kev loj hlob ntawm thev naus laus zis, hubs tau maj mam dhau mus thiab hloov los ntawm cov keyboards hauv cheeb tsam hauv zos, tshwj xeeb tshaj yog cov loj thiab nruab nrab. hubs feem ntau yog siv rau ntawm cov npoo ntawm qee qhov me me thiab nruab nrab cov tes hauj lwm lossis cov tes hauj lwm loj thiab nruab nrab. Cov hauv qab no yog ib qho kev qhia txog kev xaiv rau me me thiab nruab nrab hauv cheeb tsam network, nrog rau lawv daim ntawv thov raws li tus yam ntxwv.
