Hloov (Switch) txhais tau hais tias "hloov" thiab yog ib qho khoom siv network siv rau hluav taws xob (optical) teeb liab xa mus.Nws tuaj yeem muab txoj hauv kev tshwj xeeb hluav taws xob rau ib qho ob lub network nodes ntawm kev nkag mus.Cov keyboards feem ntau yog Ethernet keyboards.Lwm qhov sib xws yog xov tooj lub suab keyboards, fiber ntau keyboards thiab lwm yam.
Lub luag haujlwm tseem ceeb ntawm kev hloov pauv muaj xws li qhov chaw nyob ntawm lub cev, lub network topology, kev kuaj xyuas qhov yuam kev, ntu ntu, thiab tswj kev ntws.Qhov hloov pauv kuj muaj qee qhov haujlwm tshiab, xws li kev txhawb nqa rau VLAN (Virtual Local Area Network), kev txhawb nqa rau kev sib txuas sib txuas, thiab qee qhov tseem muaj qhov ua haujlwm ntawm firewall.
1. Zoo li hubs, keyboards muab ntau qhov chaw nres nkoj rau cabling, tso cai rau cabling hauv lub hnub qub topology.
2. Zoo li repeaters, hubs, thiab txuas hniav, ib qho kev hloov dua siab tshiab yuav ua rau lub teeb liab hluav taws xob tsis hloov pauv thaum nws xa mus rau thav ntawv.
3. Zoo li cov txuas hniav, cov keyboards siv tib qhov kev xa mus lossis lim cov logic ntawm txhua qhov chaw nres nkoj.
4. Zoo li tus choj, qhov hloov pauv tau faib cov cheeb tsam hauv cheeb tsam rau hauv ntau qhov kev sib tsoo, txhua tus muaj ib qho kev ywj pheej bandwidth, yog li kev txhim kho bandwidth ntawm cov cheeb tsam hauv cheeb tsam.
5.Ntxiv rau kev ua haujlwm ntawm cov txuas hniav, hubs, thiab rov ua haujlwm dua, cov keyboards muaj cov yam ntxwv siab dua xws li virtual hauv cheeb tsam network (VLANs) thiab kev ua haujlwm siab dua.
