Ezweni elihlale elivelayo lobuchwepheshe, izinto ezithile ezintsha zivela njengezikhathi ezimnandi ezakha kabusha isimo sezokuxhumana sedijithali. Ukuqamba okukodwa okunjalo yi-Network Shintsha, idivaysi ebaluleke kakhulu kumabhizinisi namanethiwekhi wezimboni. Ukudalwa kokushintshwa kwenethiwekhi kumakwe i-Shift enkulu ngendlela idatha yendlela idluliselwa futhi ilawulwa, ibamba amanethiwekhi asebenza kahle futhi anokwethenjelwa. Le ndatshana idonsela emgabeni wokushintshwa kwenethiwekhi kanye nomthelela wawo omkhulu kumanethiwekhi wanamuhla.
Umsuka wokushintshwa kwenethiwekhi
Umqondo wokushintshwa kwenethiwekhi uqhamuke ekuqaleni kweminyaka yama-1990s ukuphendula ubulukhuni obukhulayo kanye nezidingo zamanethiwekhi ekhompyutha. Ngaphambi kokusungula kwabo, amanethiwekhi athembele ngokuyinhloko kuma-hubs namabhuloho, okuthi, ngenkathi esebenza ngempumelelo, ayenokulinganiselwa, ikakhulukazi ngokwesikali, ukusebenza kahle kanye nokuphepha.
Isibonelo, i-HUB iyithuluzi elilula elidlulisela idatha kuwo wonke amadivayisi kunethiwekhi, kungakhathalekile ukuthi umemukeli ohlosiwe. Lokhu kuholela ekuxinekeni kwenethiwekhi, ukungasebenzi kahle, kanye nezingozi zokuphepha ngoba wonke amadivaysi athola wonke amaphakethe, ngisho nalabo okungeyona eyabo. Amabhuloho ahlinzeke ngentuthuko ethile ngokuhlukanisa inethiwekhi ezingxenyeni ezithile, kepha ayisakwazi ukuphatha imithwalo yedatha eyandayo noma ukuhlinzeka ngokulawula okudingekayo ngamanethiwekhi wanamuhla.
Ukubona lezi zinselelo, amaphayona wenethiwekhi afuna ikhambi elingaphatha ithrafikhi yedatha ngobuhlakani. Lokhu kuhlola kuholele ekuthuthukisweni kokushintshwa kwenethiwekhi yokuqala, amadivaysi akwazi ukuqondisa amaphakethe wedatha kuphela endaweni yawo okuhlosiwe, ngcono kakhulu ukusebenza kahle kwenethiwekhi nokuphepha.
Shintsha inethiwekhi yokuqala
Ukushintshwa kwenethiwekhi yokuqala okuphumelelayo kwezentengiselwano kwezethulwe ngo-1990 nguKalpana, inkampani encane yokuxhumana. Ukusungulwa kukaKalpana kwakuyithuluzi le-multiport elalisebenzisa ubuchwepheshe obubizwa ngokuthi "ukushintshana kohlaka" ukuqondisa amaphakethe kumachweba athile asuselwa ekhelini lawo. Lokhu okusha kunciphisa kakhulu ithrafikhi yedatha engadingekile kwinethiwekhi, kuveze indlela yokuxhumana okusheshayo nokuthe xaxa.
Ukushintshwa kwenethiwekhi kaKalpana kwasheshe kwathandwa futhi impumelelo yayo idonsele ukunakwa. Amasistimu weCisco, umdlali omkhulu embonini yezingosi zokuxhumana, athola iKalpana ngo-1994 ukuhlanganisa ubuchwepheshe bokushintshana emgqeni wawo womkhiqizo. Ukutholwa kuphawulwe ukuqala kokwamukelwa okwenziwe ngamehlo okuguqulwa kwenethiwekhi emhlabeni jikelele.
Umthelela kuwebhu yesimanje
Ukwethulwa kwenethiwekhi Ukushintshwa Kwenethiwekhi Kuguquko Izinethiwekhi ngezindlela ezimbalwa ezibalulekile:
Ukwanda kokusebenza kahle: Ngokungafani ne-HUB esakaza idatha kuwo wonke amadivayisi, i-HUB idlulisela kuphela idatha kumadivayisi athile adingayo. Lokhu kunciphisa kakhulu ukugcwala kwenethiwekhi futhi kuvumela ukusetshenziswa okusebenzayo kwe-bandwidth.
Ukuphepha okuthuthukile: Ngokulawula ukuhamba kwedatha, ukushintshwa kwehlisa ithuba lokuqonda kwedatha, ukuhlinzeka ngendawo ephephile yenethiwekhi.
Ukwehla: Ukushintshwa kwenethiwekhi kunika amandla ukudalwa kwamanethiwekhi amakhulu, amanethiwekhi ayinkimbinkimbi, avumele izinhlangano ukuba zilinganise ingqalasizinda yazo yedijithali ngaphandle kokuyekethisa ukusebenza.
Ukusekelwa kobuchwepheshe besimanje: Ukushintshwa kwenethiwekhi sekuvele ukuhambisana nentuthuko yezobuchwepheshe, ukusekela amanani okudlulisela idatha ngokushesha, amandla ngaphezulu kwamandla we-Ethernet (POE), namakhono okuphathwa kwenethiwekhi athuthukile.
Ukuvela kokushintshwa kwenethiwekhi
Ukushintshwa kwenethiwekhi sekuguqulwe okubalulekile kusukela kwasungulwa. Kusuka ku-Basic Earler 2 switchs ephatha idatha elula yokudlulisela ku-advelted ungqimba ama-3 switch
Namuhla, ukushintshwa kwenethiwekhi kubalulekile ekusebenzeni kwezikhungo zedatha, amanethiwekhi webhizinisi kanye nezindawo zezimboni. Basekela izinhlobo eziningi zezicelo, kusuka ekuxhumaniseni amadivaysi e-IOT futhi banikeze amandla ezakhiwo ze-Smart, ukunika amandla ukufinyelela okuphezulu kwe-Intanethi futhi kusiza i-Computing Cloud.
Ngifuna ikusasa
Njengoba siqhubekela enkathini yenguquko yedijithali, iqhaza lokushintshwa kwenethiwekhi lizoqhubeka nokuvela. Ngokuqala kwe-5G, i-Computing ye-Edge kanye ne-Intanethi yezinto (iot), isidingo sezixazululo ezinamandla neziguquguqukayo zizokwanda kuphela. Ukushintshwa kwenethiwekhi kunekhono lokuzivumelanisa nalezi zinselelo ezintsha futhi kuzoqhubeka nokuba phambili kwale ntuthuko, ukuqinisekisa ukuthi idatha ingahamba ngomthungo, ngokuphepha nangokuphumelelayo ezweni lethu elixhumeke ngokwengeziwe.
Ekuphetheni
Ukuzalwa kokushintshwa kwenethiwekhi kuyinto enamanzi emlandweni wokuxhumana kwedijithali. Kuguqulwe indlela idatha ephethwe futhi yadluliselwa ngamanethiwekhi, ibeka isisekelo samanethiwekhi athuthukile, ahlelekile futhi aphephile esincike kukho namuhla. Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, ukushintshwa kwenethiwekhi ngokungangabazeki kuzodlala indima enkulu ekubumbeni ikusasa lokuxhumana komhlaba wonke.
