Kwihlabathi lezobuchwephesha elihlala lihlala livela, izinto ezithile ezibonakalayo zivele njengamaxesha achukunyisayo ephindaphindiweyo emhlabeni wedijithali. Enye into efana nenethiwekhi itshintshiwe, isixhobo esingenakuphikwa kwishishini kunye neenethiwekhi zeshishini. Ukudalwa kwee-switch yenethiwekhi kuphawuleka utshintsho olukhulu kwindlela yedatha edluliselweyo kwaye ilawulwa, kubangela ukuba uthungelwano lube nenethiwekhi efanelekileyo. Eli nqaku lihlala liphuma kwimvelaphi yokutshintsha kwenethiwekhi kunye nefuthe labo kakhulu kwinethiwekhi yanamhlanje.
Imvelaphi ye-switch yenethiwekhi
Umxholo we-switches yenethiwekhi evele ekuqaleni kweminyaka yo-1990 ukuphendula ekwandiweni kobunzima kunye neemfuno zenethiwekhi zekhompyuter. Phambi kokuba kufakelwe, iinethiwekhi zazo zixhomekeke ikakhulu kwii-hubs kunye neebhulorho, ezithi, ngelixa zisebenza, zinomda, ngokukodwa ngokhuseleko.
Umzekelo, i-hub sisixhobo esilula esiguqula idatha kuzo zonke izixhobo kwinethiwekhi, ngaphandle komamkeli. Oku kukhokelela kwinethiwekhi yokuxinana, ukungasebenzi kakuhle, kunye nengozi yokhuseleko kuba zonke izixhobo zifumana zonke iipakethi, kwanabo bangengabo. Iibhulorho zibonelela ngokuphuculwa ngokwahlulahlula uthungelwano zibe ngamacandelo, kodwa zange bakwazi ukuphatha imithwalo yokwanda kwedatha okanye ukubonelela ngolawulo olufunwa ngu-Nutors.
Ukuqonda le miceli mngeni, oovulindlela beenethiwekhi bafuna isisombululo esinokulawula idatha ngengqondo. Oku kuphononongwa kukhokelele kuphuhliso lwenethiwekhi yokuqala yenethiwekhi, izixhobo ezinokuthi zikhokele iipakethi zedatha kwindawo yazo, ukuphucula kakhulu ukusebenza kwenethiwekhi kunye nokhuseleko.
Ukutshintsha kwenethiwekhi kuqala
Ukutshintsha kwenethiwekhi yokuqala kwezorhwebo kwasungulwa ngo-1990 ngeKalina, inkampani encinci yokunxibelelana. I-kalpana i-Kalpana yayisisixhobo esininzi esisebenzisa itekhnoloji ebizwa ngokuba yi "Free Swipng" ukuya ngqo kwiipakethi kumazibuko athile esekwe kwidilesi yabo yendawo. Ukunciphisa kakhulu itrafikhi engafunekiyo kwinethiwekhi, ityhila indlela yokufumana unxibelelwano ngokukhawuleza nolwazingaphezulu.
Ukutshintsha kwenethiwekhi kaKalpana kwathandwa kwaye impumelelo yayo yatsala umdla. Inkqubo yeCisco, umdlali ophambili kumzi-mveliso wokunxibelelana, ofunyenwe uKalpana ngo-1994 ukudibanisa itekhnoloji yokutshintsha kumgca wayo wemveliso. Ukufunyanwa kwakuphawula ukuqala kokwamkelwa komntwana abe ngowakho kwinethiwekhi ekhangela inethiwekhi kwihlabathi liphela.
Impembelelo kwiWebhu yanamhlanje
Ukuqaliswa kwenethiwekhi yokutshintsha kwenethiwekhi kwiindlela ezininzi eziphambili:
Ukwanda kokusebenza: Ngokungafaniyo nosasazo lwedatha kuzo zonke izixhobo, i-hub idlulisela idatha kuphela kwizixhobo ezithile eziyifunayo. Oku kunciphisa kakhulu ukuxinana kwenethiwekhi kwaye kuvumela ukusetyenziswa ngokukuko kwe-bandwidth.
Ukhuseleko oluphuculweyo: Ngokulawula ukuhamba kwedatha, i-switch inciphise ithuba lokufumana idatha, ukubonelela ngendawo ekhuselekileyo yenethiwekhi.
I-ScAlance: Ukutshintsha kwenethiwekhi kwenza ukuba i-Netchsayithi enkulu, ivumela imibutho enzima, ivumela imibutho ukuphakamisa iziseko zophuhliso zedijithali ngaphandle kokusebenza kakuhle.
Inkxaso yeTekhnoloji yale mihla: Ukutshintshwa kwenethiwekhi kuye kwavela ukuqhubela phambili ngenkqubela phambili yetekhnoloji, ukuxhasa amaxabiso okudluliselwa kwedatha ngokukhawuleza, amandla ngaphezulu kwe-Ethernet (PoE), kunye neZakhono zoLawulo lwenethiwekhi.
Indaleko ye-switch yenethiwekhi
Ukutshintshwa kwenethiwekhi kuye kwenziwa indaleko ebalulekileyo okokuqalisa kwabo. Ukusuka kwi-Swings esisiseko 2 Ukutshintsha kwedatha elula ekudluliseleni ungqimba oluPhambili-3 ukutshintshela okubandakanya amandla emiboleko, itekhnoloji iyaqhubeka ukuqhubela phambili ukuhlangabezana neemfuno ezikhulayo zothungelwano olukhulayo.
Namhlanje, ukutshintshelwa kwenethiwekhi kunxulumene nokusebenza kwamaziko edatha, iinethiwekhi zeshishini kunye neendawo ezisebenza kwimizi mveliso. Baxhasa uluhlu olubanzi lwezicelo, ekukhuthazeni izixhobo ze-IOI kunye nezakhiwo ze-smand, ukunika amandla okufikelela kwi-Intanethi ephezulu kunye nokwenza lula ikhompyuter yelifu.
Ukujonga kwikamva
Njengoko sihamba ngakumbi kwixesha lenguquko yedijithali, indima yokutshintsha kwenethiwekhi iya kuqhubeka nokuvela. Ngokuqala kwe-5G, i-computer yomphetho kunye ne-Intanethi yezinto (IOI), isidingo sezisombululo ezinamandla nenethiwekhi eziguqukayo ziya kunyuka kuphela. Ukutshintshelwa kwenethiwekhi kubanakho ukuziqhelanisa nale miceli mngeni kwaye kuya kuqhubeka nokuba kwindawo ephambili kolu phuhliso, ukuqinisekisa ukuba idatha ingahambanga ngokuthembekileyo, ngokukhuselekileyo nangokufanelekileyo kwihlabathi lethu elidibeneyo.
ukuququmbela
Ukuzalwa kwe-Switch yenethiwekhi kunamanzi kwimbali yonxibelelwano lwedijithali. Itshintshele i-datha elawulwa yidatha kwaye idluliselwa ngaphezulu kwenethiwekhi, ibeka isiseko senethiwekhi ekhulileyo, enesikhafu kunye nokukhusela iinethiwekhi. Njengoko itekhnoloji iyaqhubeka ukuqhubela phambili, ukutshintsha kwenethiwekhi ngokungathandabuzekiyo kuya kudlala indima ephakathi ekwakheni ikamva lokunxibelelana kwehlabathi.
