Industrial switchesdzakagadzirirwa chaizvo kusangana nezvinodiwa zvekuchinjika uye zvinochinjika maindasitiri maapplication uye inopa inodhura-inoshanda maindasitiri Ethernet yekukurukurirana mhinduro.Kuchinja kwemaindasitiri, semidziyo yedu inoshandiswa zvakanyanya yeLAN hardware, yagara ichizivikanwa kune wese munhu.Kukurumbira kwayo kuri kukonzerwa nekushandiswa kwakapararira kweEthernet, semidziyo yemazuva ano yeEthernet, pachave nemidziyo yakadaro munharaunda yese network.

Maindasitiri anochinja machinjo anobva paEthernet kufambisa data, uye Ethernet inoshandisa network yenzvimbo inogovera bhazi-rudzi rwekufambisa.Chimiro cheEthernet switch ndechekuti chiteshi chega chega chakabatana zvakananga kune mugamuchiri, uye kazhinji chinoshanda mune yakazara-duplex modhi.Iyo switch inogona kubatana kune akawanda mapeya ezviteshi panguva imwe chete, kuitira kuti imwe neimwe yemauto anotaurirana anogona kutumira data pasina kupokana sekunge ingori nzira yekutaurirana chete.Tichitarisa zvinotevera topology, uchaona kuti panyaya kushandisa nyeredzi topology, pachava zvisingadzivisiki kuva chinja muna Ethernet, nokuti mauto ose akabatana indasitiri chinja vachishandisa tambo kuti kubatanidza kune mumwe.

Muchokwadi, mune yekutanga nyeredzi topology, iyo yakajairwa tambo yepakati yekubatanidza mudziyo ndeye "HUB (hub)", asi hubs ine matambudziko akadai sekugovana bandwidth, kukakavara pakati pezviteshi, nekuti munhu wese anoziva kuti standard Ethernet i "hub".Conflict network” zvinoreva kuti mune inonzi “conflict domain”, kazhinji node mbiri dzinogona kutaurirana.Uyezve, kunyange zvazvo hubhu ine zviteshi zvakawanda, chimiro chayo chemukati chiri zvachose chinonzi "bhazi chimiro" cheEthernet, zvinoreva kuti kune "mutsara" mumwe chete mukati mekukurukurirana.Kana iwe ukashandisa hub mudziyo, semuenzaniso, kana node dziri pakati pezviteshi 1 uye 2 dziri kutaurirana, mamwe madoko anofanira kumirira.Chiitiko chakakonzeresa zvakananga ndechekuti, semuenzaniso, zvinotora maminetsi gumi kutumira data pakati pemanodhi akabatana nechiteshi 1 uye 2, uye node uko madoko 3 ne4 anowanikwa panguva imwe chete anotangawo kutumira data kuburikidza nehubhu iyi, kukakavara. nemumwe nemumwe, zvichikonzera zvinodiwa nemunhu wese Nguva ichange yakareba, uye zvinogona kutora kusvika maminetsi makumi maviri kupedzisa kutapurirana.Kureva kuti, iyo yakawanda madoko pane hubhu inotaurirana kune mumwe nemumwe, iyo yakanyanya kunetsa kunetsana, uye iyo yakareba inotora kuendesa data.

Hunhu hwemuviri hwemaindasitiri switch anoreva maitiro ekutaridzika, hunhu hwekubatanidza hunhu, dhizaini yekumisikidza, base mhando, kugona kwekuwedzera, kugona kurongedza uye zviratidziro zvinopihwa ne switch, inoratidza mamiriro ekutanga ekuchinja.

Iyo switching tekinoroji chigadzirwa chekuchinja chine hunhu hwekureruka, mutengo wakaderera, kuita kwepamusoro uye yakakwirira port density, iyo inomiririra yakaoma switching tekinoroji yebridging tekinoroji muchikamu chechipiri cheOSI referenzi modhi.Kufanana nebhiriji, switch inoita sarudzo yakapusa yekuendesa ruzivo zvinoenderana nekero yeMAC mupaketi yega yega.Uye iyi sarudzo yekutumira kazhinji haitarise rumwe ruzivo rwakadzama rwakavigwa mupacket.Musiyano nemabhiriji ndewekuti kunonoka kwekufambisa kwekuchinja kudiki kwazvo, padyo nekuita kweLAN imwe chete, uye inodarika zvakanyanya kuita kwekutumira pakati peakajairwa mabhiriji ekubatanidza network.

Kuchinja tekinoroji inobvumira bandwidth kugadziridzwa kweakagovaniswa uye akazvitsaurira LAN zvikamu kudzikisa mabhodhoro mukuyerera kweruzivo pakati peLAN.Kune zvinochinjisa zvigadzirwa zveEthernet, Fast Ethernet, FDDI uye ATM tekinoroji.

Kushandiswa kwemasekete akanyatsogadzirwa akabatanidzwa kunoita kuti shanduko ienderere mberi ruzivo rwakafanana pamachiteshi ese pamutsetse wemutsetse, ichipa kuita kwakakwirira kudarika mabhiriji echinyakare.Iyo yekushandisa-chaiyo yakasanganiswa yedunhu tekinoroji inoita kuti shanduko ishande neyakadudzwa pamusoro pekuita mune mamwe madoko, uye mutengo wayo wechiteshi wakaderera pane webhiriji rechinyakare.

Industrial switches inoshandiswa zvakanyanya.Panyaya yekushandiswa kwemaindasitiri, anonyanya kushandiswa mu: chengetedzo yemugodhi wemarasha, njanji yekufambisa, fekitori otomatiki, masisitimu ekurapa mvura, kuchengetedzwa kwemadhorobha, nezvimwe.
