Kwihlabathi elihlala liguquka letekhnoloji, iinguqulelo ezithile zigqama njengamaxesha abalulekileyo ahlengahlengisa ubume bonxibelelwano lwedijithali. Olunye ulutsha olunjalo lutshintsho lwenethiwekhi, isixhobo esiyimfuneko kuthungelwano lweshishini kunye nezoshishino. Ukwenziwa kokutshintsha kwenethiwekhi kuphawule utshintsho olukhulu kwindlela yokuhanjiswa nokulawulwa kwedatha, okukhokelela kuthungelwano olusebenzayo, olunokwehla noluthembekileyo. Eli nqaku lijonge kwimvelaphi yokutshintsha kwenethiwekhi kunye nefuthe labo elinzulu kuthungelwano lwanamhlanje.
Imvelaphi yoTshintsho lweNethiwekhi
Ingqikelelo yokutshintsha kwenethiwekhi yavela ekuqaleni kweminyaka yoo-1990 ekuphenduleni ukwanda kobunzima kunye neemfuno zothungelwano lwekhompyuter. Ngaphambi kokuveliswa kwazo, uthungelwano lwaluxhomekeke ikakhulu kwii-hubs kunye neebhulorho, ezithi, ngelixa zisebenza, zinemida, ngakumbi ngokubhekiselele kwi-scalability, ukusebenza kakuhle kunye nokhuseleko.
Ngokomzekelo, i-hub sisixhobo esilula esithumela idatha kuzo zonke izixhobo kwinethiwekhi, kungakhathaliseki ukuba ngubani ocetywayo. Oku kukhokelela kwingxinano yothungelwano, ukungasebenzi kakuhle, kunye nemingcipheko yokhuseleko enokubakho kuba zonke izixhobo zifumana zonke iipakethi, kwanezo zingezozazo. Iibhulorho zibonelele ngophuculo ngokwahlula-hlula uthungelwano ngokwamacandelo, kodwa abakwazanga ukumelana nokwanda kwemithwalo yedatha okanye ukunika ulawulo olufunwa luthungelwano lwale mihla.
Ukuqaphela le mingeni, oovulindlela benethiwekhi bafuna isisombululo esinokulawula ukuthuthwa kwedatha ngobuchule. Olu phononongo lwakhokelela ekuphuhlisweni kokutshintsha kwenethiwekhi yokuqala, izixhobo ezinokuthi ziqondise kuphela iipakethi zedatha kwindawo yazo ekujoliswe kuyo, ukuphucula kakhulu ukusebenza kwenethiwekhi kunye nokhuseleko.
inethiwekhi yokuqala yokutshintsha
Ukutshintshwa kwenethiwekhi yokuqala eyimpumelelo yorhwebo yasungulwa ngo-1990 nguKalpana, inkampani encinci yenethiwekhi. Ukuveliswa kwe-Kalpana yayisisixhobo se-multiport esasebenzisa iteknoloji ebizwa ngokuthi "ukutshintshwa kwefreyimu" ukuqondisa iipakethi kwiichweba ezithile ezisekelwe kwidilesi yazo. Olu lutsha lunciphisa kakhulu ukugcwala kwedatha okungafunekiyo kwinethiwekhi, kuvula indlela yonxibelelwano olukhawulezayo noluthembekileyo.
Ukutshintsha kwenethiwekhi yeKalpana ngokukhawuleza kwaduma kwaye impumelelo yayo yatsala ingqalelo. I-Cisco Systems, umdlali omkhulu kumashishini onxibelelwano, wafumana i-Kalpana kwi-1994 ukudibanisa iteknoloji yokutshintsha kumgca wayo wemveliso. Ukufunyanwa kuphawule ukuqala kokwamkelwa ngokubanzi kokutshintsha kwenethiwekhi kwihlabathi liphela.
Impembelelo kwiwebhu yanamhlanje
Ukuqaliswa kokutshintsha kwenethiwekhi kuguqule uthungelwano ngeendlela ezininzi eziphambili:
Ukonyuka kokusebenza kakuhle: Ngokungafaniyo ne-hub esasaza idatha kuzo zonke izixhobo, i-hub idlulisela kuphela idatha kwizixhobo ezithile eziyifunayo. Oku kunciphisa kakhulu ukuxinana kwenethiwekhi kwaye kuvumela ukusetyenziswa ngokufanelekileyo kwe-bandwidth.
Ukhuseleko oluphuculweyo: Ngokulawula ukuhamba kwedatha, ukutshintshwa kunciphisa ithuba lokubanjwa kwedatha, ukubonelela ngemeko yenethiwekhi ekhuselekileyo.
I-Scalability: Ukutshintshwa kwenethiwekhi kuvumela ukudala uthungelwano olukhulu, olunzima ngakumbi, oluvumela imibutho ukuba ikhulise iziseko zabo zedijithali ngaphandle kokuphazamisa ukusebenza.
Inkxaso yezobuchwepheshe zanamhlanje: Ukutshintsha kwenethiwekhi kuye kwavela ukuze kuhambisane nenkqubela phambili yezobuchwepheshe, ukuxhasa amazinga okudlulisa idatha ngokukhawuleza, Amandla phezu kwe-Ethernet (i-PoE), kunye nobuchule obuphezulu bolawulo lwenethiwekhi.
Inguquko yokutshintsha kwenethiwekhi
Ukutshintsha kweNethiwekhi kuye kwavela kwinguqu ebalulekileyo ukusukela ekusekweni kwabo. Ukusuka kwiiswitshi ezisisiseko zoMaleko wesi-2 ezijongana nokuhanjiswa kwedatha ngokulula ukuya kutshintsho oluphambili lweLayer 3 olubandakanya ubuchule bokukhokela, itekhnoloji iyaqhubeka nokuqhubela phambili ukuhlangabezana neemfuno ezikhulayo zothungelwano lwale mihla.
Namhlanje, utshintsho lwenethiwekhi luyimfuneko ekusebenzeni kwamaziko edatha, uthungelwano lwamashishini, kunye neendawo zoshishino. Baxhasa uluhlu olubanzi lwezicelo, ukusuka ekudibaniseni izixhobo ze-IoT kunye nokunika amandla izakhiwo ezihlakaniphile, ukunika amandla ukufikelela kwi-Intanethi ngesantya esiphezulu kunye nokuququzelela i-computing yefu.
Ukujonga kwikamva
Njengoko siqhubela phambili kwixesha lenguqu yedijithali, indima yokutshintsha kwenethiwekhi iya kuqhubeka nokuvela. Ngokufika kwe-5G, i-edge computing kunye ne-Intanethi yezinto (IoT), imfuno yezisombululo zenethiwekhi ezinamandla kunye neziguquguqukayo ziya kwanda kuphela. Ukutshintsha kweNethiwekhi kunamandla okuziqhelanisa nale mingeni mitsha kwaye kuya kuqhubeka kuphambili kolu phuhliso, ukuqinisekisa ukuba idatha inokuhamba ngokungenamthungo, ngokukhuselekileyo nangokufanelekileyo kwihlabathi lethu elixhaphakileyo.
ukuququmbela
Ukuzalwa kokutshintsha kwenethiwekhi yindawo yamanzi kwimbali yonxibelelwano lwedijithali. Itshintshe indlela idatha elawulwa ngayo kwaye idluliselwe kuthungelwano, ibeka isiseko sothungelwano oluphambili, olunomngcipheko kunye nolukhuselekileyo esixhomekeke kulo namhlanje. Njengoko itekhnoloji iqhubela phambili, ukutshintshwa kwenethiwekhi ngokungathandabuzekiyo kuya kudlala indima ephambili ekubumbeni ikamva loqhagamshelwano lwehlabathi.
