Hauv lub ntiaj teb kev sib txuas, ob qho khoom siv yooj yim feem ntau tshwm sim: keyboards thiab routers. Txawm hais tias ob qho tib si ua lub luag haujlwm tseem ceeb hauv kev sib txuas cov khoom siv, lawv muaj cov haujlwm sib txawv hauv lub network. Kev nkag siab txog qhov sib txawv ntawm ob tuaj yeem pab cov lag luam thiab cov tib neeg ua cov kev xaiv paub thaum tsim lossis nthuav lawv cov txheej txheem network.
Lub luag haujlwm ntawm cov keyboards network
Network keyboards ua haujlwm nyob rau hauv ib cheeb tsam hauv cheeb tsam network (LAN) los txuas ntau yam khoom siv, xws li khoos phis tawj, tshuab luam ntawv, thiab IP koob yees duab. Nws lub luag haujlwm tseem ceeb yog txhawm rau ua kom muaj kev sib txuas lus zoo ntawm cov khoom siv no los ntawm kev coj cov ntaub ntawv mus rau qhov chaw raug nyob hauv lub network.
Cov hloov pauv txheeb xyuas cov khoom siv hauv lub network los ntawm kev siv MAC (Media Access Control) chaw nyob. Thaum ib lub cuab yeej xa cov ntaub ntawv, tus hloov mus rau nws tshwj xeeb rau tus neeg tau txais kev pab es tsis tshaj tawm nws mus rau txhua lub cuab yeej txuas nrog. Txoj kev tsom mus rau qhov no pab txuag bandwidth thiab nce kev sib txuas ceev, ua rau kev hloov pauv zoo rau cov ntaub ntawv xov xwm siab xws li chaw ua haujlwm, tsev kawm ntawv thiab cov chaw khaws ntaub ntawv.
Lub luag haujlwm ntawm router
Tsis zoo li qhov hloov pauv, uas tsuas yog txwv rau ib lub network nkaus xwb, lub router ua raws li tus choj ntawm cov tes hauj lwm sib txawv. Hauv kev teeb tsa hauv tsev lossis kev lag luam, lub router txuas lub network hauv zos rau Is Taws Nem. Nws ua raws li lub rooj vag uas tswj cov ntaub ntawv nkag thiab tawm, kom ntseeg tau tias cov ntaub ntawv los ntawm Is Taws Nem mus txog qhov raug ntaus ntawv hauv LAN thiab rov ua dua.
Routers siv IP (Internet Protocol) chaw nyob rau xa cov ntaub ntawv ntawm tes hauj lwm. Lawv ua haujlwm ntau dua li cov keyboards, suav nrog muab IP chaw nyob rau cov khoom siv hauv lub network, tswj kev ruaj ntseg network, thiab muab kev tiv thaiv firewall.
Qhov tseem ceeb sib txawv ntawm Hloov thiab Router
Ntawm no yog ib qho kev tawg ntawm qhov sib txawv tseem ceeb ntawm ob lub cuab yeej:
Function thiab Scope:
Hloov: Ua haujlwm hauv ib lub network hauv zos, txuas cov khoom siv thiab ua kom yooj yim sib pauv cov ntaub ntawv ntawm lawv.
Router: Txuas cov tes hauj lwm sib txawv, feem ntau txuas lub network hauv zos mus rau Is Taws Nem thiab tswj cov ntaub ntawv khiav mus rau thiab los ntawm lwm qhov chaw.
Chaw nyob system:
Hloov: Siv MAC chaw nyob los txheeb xyuas thiab sib txuas lus nrog cov khoom siv. Txoj hauv kev no zoo heev rau kev tswj cov ntaub ntawv ntws hauv lub network kaw.
Router: Siv IP chaw nyob rau kev xa cov ntaub ntawv ntawm tes hauj lwm, uas yog qhov tseem ceeb rau kev sib txuas lus hauv Is Taws Nem thiab nkag mus rau lwm lub network.
Data routing thiab data forwarding:
Hloov: xa cov ntaub ntawv ncaj qha mus rau cov khoom siv tshwj xeeb hauv lub network, ua rau cov ntaub ntawv sab hauv ntws tau zoo dua.
Router: Kev xa cov ntaub ntawv hla ntau lub network, xyuas kom meej tias cov ntaub ntawv mus txog qhov tseeb, txawm nyob hauv lub network hauv zos lossis sab nraum lub network.
Kev ruaj ntseg nta:
Hloov: Feem ntau muaj cov kev xaiv kev ruaj ntseg yooj yim, tsom rau kev tswj cov ntaub ntawv sab hauv. Txawm li cas los xij, cov keyboards tswj tau muaj qee qhov kev ruaj ntseg zoo xws li VLAN (virtual LAN) segmentation thiab kev ua haujlwm tseem ceeb.
Router: Muaj kev ruaj ntseg nta xws li firewall, NAT (Network Address Translation), thiab qee zaum VPN txhawb. Qhov no pab tiv thaiv lub network los ntawm kev hem sab nraud thiab tsis tau tso cai.
Yuav siv li cas:
Switches: Zoo tagnrho rau ib puag ncig uas ntau yam khoom siv yuav tsum sib txuas lus hauv tib lub network, xws li chaw ua haujlwm, tsev kawm ntawv, thiab cov chaw khaws ntaub ntawv.
Router: Qhov tseem ceeb rau kev txuas koj lub network hauv zos mus rau lwm lub network, xws li Is Taws Nem, ua rau nws yog ib qho tseem ceeb rau kev sib txuas hauv tsev thiab kev lag luam.
Koj puas xav tau ob qho tib si?
Rau kev teeb tsa feem ntau, yuav tsum muaj qhov hloov pauv thiab router. Nyob rau hauv ib lub tsev network ib txwm, ib lub router txuas koj cov khoom siv rau hauv Is Taws Nem, thiab ib qho kev hloov (txawm yog muab tso rau hauv router lossis cais) tswj kev sib txuas ntawm cov khoom siv hauv tib lub network. Rau kev lag luam thiab ib puag ncig loj, cov keyboards siab siv feem ntau siv los tswj cov kev khiav tsheb sab hauv, thaum routers tswj kev sib txuas ntawm LAN thiab dav Internet.
nyob rau hauv xaus
Cov keyboards thiab routers ua haujlwm ua ke los tsim kom muaj kev sib txuas thiab ua haujlwm tau zoo, nrog rau txhua qhov hloov pauv ua tiav lub luag haujlwm tshwj xeeb. Hloov ua kom zoo dua kev sib txuas lus hauv lub network los ntawm kev coj cov ntaub ntawv mus rau cov khoom siv tshwj xeeb, thaum routers tswj kev sib txuas sab nraud, txuas cov tes hauj lwm hauv zos rau hauv Is Taws Nem thiab tiv thaiv cov ntaub ntawv tsheb. Los ntawm kev nkag siab qhov sib txawv ntawm ob lub cuab yeej no, koj tuaj yeem txiav txim siab paub ntau ntxiv txog koj lub network infrastructure thiab xyuas kom nws ua tau raws li koj qhov kev xav tau kev sib txuas thiab kev nyab xeeb.
Raws li kev siv thev naus laus zis txuas ntxiv mus, cov keyboards thiab routers tau dhau los ua qhov ntse dua hauv lawv lub peev xwm, muab kev lag luam thiab cov tib neeg muaj kev tswj hwm ntau dua ntawm kev ua haujlwm thiab kev ruaj ntseg ntawm lawv cov tes hauj lwm.
