Ukutshintsha kwamashishinizenzelwe ngokukodwa ukuhlangabezana neemfuno zezicelo eziguquguqukayo kunye neziguquguqukayo zemizi-mveliso kwaye zibonelele ngesisombululo esisebenzayo sonxibelelwano lwe-Ethernet yoshishino.Ukutshintsha kwamashishini, njengezixhobo zethu ze-LAN ezisetyenziswa ngokubanzi, bezisoloko ziqhelekile kumntu wonke.Ukuthandwa kwayo kungenxa yokusetyenziswa ngokubanzi kwe-Ethernet, njengezixhobo zanamhlanje ze-Ethernet, kuya kubakho izixhobo ezinjalo phantse kuzo zonke iinethiwekhi zendawo.

Ukutshintsha kwemizi mveliso kukutshintsha okusekwe kwi-Ethernet ukuhambisa idatha, kwaye i-Ethernet isebenzisa inethiwekhi yendawo yendawo eyabelana ngendlela yokuhambisa ibhasi.Ubume bokutshintsha kwe-Ethernet kukuba izibuko ngalinye liqhagamshelwe ngokuthe ngqo kumamkeli, kwaye lisebenza ngokubanzi kwimowudi ephindwe kabini.Ukutshintsha kunokudibanisa izibini ezininzi zamazibuko ngaxeshanye, ukuze isibini ngasinye semikhosi esinxibelelana nomnye sithumele idatha ngaphandle kongquzulwano ngokungathi sisixhobo sonxibelelwano esikhethekileyo.Ukujonga i-topology elandelayo, uya kufumanisa ukuba kwimeko yokusebenzisa i-topology yeenkwenkwezi, ngokuqinisekileyo kuya kubakho ukutshintshela kwi-Ethernet, kuba yonke imikhosi ixhunyiwe kwi-industrial switch usebenzisa iintambo zokudibanisa.

Enyanisweni, kwi-topology yokuqala yeenkwenkwezi, i-standard cable centralized device i-"HUB (hub)", kodwa ii-hubs zineengxaki ezifana ne-bandwidth ekwabelwanayo, iingxabano phakathi kwamachweba, kuba wonke umntu uyazi ukuba i-Ethernet eqhelekileyo "i-hub".Inethiwekhi yongquzulwano” ithetha ukuba kwindawo ebizwa ngokuba “yi-conflict domain”, kwezona ndawo zimbini zinokunxibelelana.Ngaphezu koko, nangona i-hub inamachweba amaninzi, isakhiwo sayo sangaphakathi siyinto ebizwa ngokuba "isakhiwo sebhasi" ye-Ethernet, oku kuthetha ukuba kukho "umgca" omnye ngaphakathi kunxibelelwano.Ukuba usebenzisa isixhobo hub, umzekelo, ukuba ii-nodes phakathi kwamachweba 1 kunye ne-2 ziyanxibelelana, amanye amazibuko kufuneka alinde.Into ebangelwa ngokuthe ngqo kukuba, umzekelo, kuthatha imizuzu eyi-10 ukuhambisa idatha phakathi kweendawo eziqhagamshelwe kumazibuko 1 kunye ne-2, kunye neendawo apho izibuko ze-3 kunye ne-4 zikhoyo ngexesha elifanayo ziqala ukuthumela idatha ngokusebenzisa le hub, iingxabano. omnye nomnye, ebangela oko wonke umntu akufunayo Ixesha liya kuba lide, kwaye kungathatha ukuya kwimizuzu engama-20 ukugqibezela usulelo.Oko kukuthi, amachweba amaninzi kwi-hub enxibelelana omnye nomnye, ingxabano enkulu, kwaye kuthatha ixesha elide ukuhambisa idatha.

Iimpawu ezibonakalayo zokutshintshwa kwemizi-mveliso zibhekiselele kwiimpawu zokubonakala, iimpawu zokudibanisa ngokomzimba, ukucwangciswa kwe-port, uhlobo lwesiseko, amandla okwandisa, ukukwazi ukupakisha kunye nezicwangciso zesalathisi ezinikezelwa ngumtshintshi, obonisa imeko esisiseko yokutshintsha.

Itekhnoloji yokutshintsha yimveliso eguqukayo eneempawu zokulula, ixabiso eliphantsi, ukusebenza okuphezulu kunye noxinaniso lwezibuko oluphezulu, oluquka iteknoloji yokutshintsha okuntsonkothileyo kwethekhnoloji yokuvala ibhuloho kwinqanaba lesibini lemodeli yereferensi ye-OSI.Njengebhulorho, iswitshi yenza isigqibo esilula sokudlulisa ulwazi ngokwedilesi ye-MAC kwipakethi nganye.Kwaye esi sigqibo sokudlulisela ngokubanzi asiyithatheli ingqalelo enye ingcaciso enzulu efihlwe kwipakethi.Umahluko ngeebhulorho kukuba ukulibaziseka kokuhanjiswa kweswitshi kuncinci kakhulu, kufutshane nokusebenza kwe-LAN enye, kwaye kugqithise kakhulu ukusebenza kogqithiso phakathi kothungelwano oludityanisiweyo oluqhelekileyo lonxibelelwano.

Ukutshintsha itekhnoloji ivumela uhlengahlengiso lwe-bandwidth kumacandelo e-LAN ekwabelwana ngawo kunye nezinikezelweyo ukuze kuncitshiswe iibhotile ekuhambeni kolwazi phakathi kweeLAN.Kukho ukutshintshwa kweemveliso ze-Ethernet, i-Fast Ethernet, i-FDDI kunye ne-ATM yeteknoloji.

Ukusetyenziswa kweesekethe ezidityanisiweyo ezilungiselelwe ngokukodwa zenza ukuba utshintsho lugqithise ulwazi ngokuhambelana kuzo zonke izibuko kwizinga lomgca, ukubonelela ukusebenza okuphezulu kakhulu kuneebhulorho zendabuko.Itekhnoloji yesekethe edibeneyo yesicelo edibeneyo yenza ukuba utshintsho lusebenze kunye nokusebenza okukhankanywe ngasentla kwimeko yamachweba amaninzi, kwaye iindleko zayo ze-port ziphantsi kunebhulorho yendabuko.

Ukutshintsha kwamashishini asetyenziswa kakhulu.Ngokubhekiselele kwizicelo zeshishini, zisetyenziswa ikakhulu kwi: ukhuseleko lomgodi wamalahle, ukuhamba ngololiwe, ukuzenzela kwefektri, iinkqubo zokucocwa kwamanzi, ukhuseleko lwasezidolophini, njl.
