Emhlabeni ohlale uvela wobuchwepheshe, izinto ezintsha eziqanjiwe zigqama njengezikhathi ezibalulekile ezilolonga kabusha isimo sokuxhumana kwedijithali. Enye yezinto ezintsha ezinjengalezi wukushintsha kwenethiwekhi, idivayisi ebaluleke kakhulu kumanethiwekhi ebhizinisi nezimboni. Ukwakhiwa kwamaswishi enethiwekhi kumake ushintsho olukhulu endleleni idatha esakazwa ngayo futhi ephathwa ngayo, okuholele kumanethiwekhi asebenza kahle kakhulu, angalawuleki futhi athembekile. Lesi sihloko sidingida umsuka wokushintsha kwenethiwekhi kanye nomthelela wabo omkhulu kumanethiwekhi esimanje.
Umsuka Wokushintsha Kwenethiwekhi
Umqondo wokushintshwa kwenethiwekhi wavela ekuqaleni kwawo-1990 ukuphendula ubunzima obukhulayo kanye nezidingo zamanethiwekhi wekhompyutha. Ngaphambi kokusungulwa kwawo, amanethiwekhi ayethembele ikakhulukazi kumahabhu namabhuloho, okuthi, nakuba esebenza kahle, abe nemikhawulo, ikakhulukazi ngokuya ngokuqina, ukusebenza kahle, kanye nokuphepha.
Isibonelo, ihabhu iyidivayisi elula edlulisela idatha kuwo wonke amadivayisi kunethiwekhi, ngaphandle kokunaka umamukeli ohlosiwe. Lokhu kuholela ekuminyanisweni kwenethiwekhi, ukungasebenzi, kanye nezingozi ezingaba khona zokuphepha ngoba wonke amadivayisi athola wonke amaphakethe, ngisho nalawo okungewona awo. Amabhuloho anikeze ukuthuthukiswa okuthile ngokuhlukanisa inethiwekhi ibe amasegimenti, kodwa awakwazanga ukuphatha ukulayishwa kwedatha okwandayo noma ukunikeza ngokulawula okudingekayo amanethiwekhi esimanje.
Ngokubona lezi zinselele, amaphayona okuxhumana afuna isixazululo esingaphatha ukutholwa kwedatha ngobuhlakani. Lokhu kuhlola kuholele ekuthuthukisweni kokushintsha kwenethiwekhi kokuqala, amadivaysi angaqondisa kuphela amaphakethe wedatha lapho aya khona, athuthukise kakhulu ukusebenza kahle kwenethiwekhi nokuphepha.
ukushintsha kwenethiwekhi yokuqala
I-switch yenethiwekhi yokuqala ephumelelayo kwezohwebo yethulwa ngo-1990 nguKalpana, inkampani encane yokuxhumana. Ukusungulwa kuka-Kalpana kwakuyithuluzi le-multiport esebenzisa ubuchwepheshe obubizwa ngokuthi “ukushintsha uzimele” ukuze kuqondiswe amaphakethe ezimbobeni ezithile ngokusekelwe ekhelini lawo. Lokhu okusha kunciphisa kakhulu ukugcwala kwedatha okungadingekile kunethiwekhi, kuvula indlela yokuxhumana okusheshayo nokuthembekile.
Ukushintsha kwenethiwekhi ka-Kalpana kwasheshe kwaduma futhi impumelelo yakhona yadonsa ukunaka. I-Cisco Systems, isidlali esikhulu embonini yezokuxhumana, ithole i-Kalpana ngo-1994 ukuze ihlanganise ubuchwepheshe bokushintshwa emgqeni womkhiqizo wayo. Ukutholwa kuphawule ukuqala kokwamukelwa kabanzi kwamaswishi enethiwekhi emhlabeni jikelele.
Umthelela kuwebhu yesimanje
Ukwethulwa kokushintsha kwenethiwekhi kuguqule ukuxhumana phakathi kwezindlela ezimbalwa ezibalulekile:
Ukusebenza okuthuthukisiwe: Ngokungafani nehabhu esakaza idatha kuwo wonke amadivayisi, ihabhu idlulisela idatha kumadivayisi athile ayidingayo. Lokhu kunciphisa kakhulu ukuminyana kwenethiwekhi futhi kuvumela ukusetshenziswa ngokuphumelelayo komkhawulokudonsa.
Ukuvikeleka okuthuthukisiwe: Ngokulawula ukuhamba kwedatha, iswishi inciphisa ithuba lokutholwa kwedatha, inikeze indawo yenethiwekhi evikeleke kakhulu.
I-Scalability: Amaswishi enethiwekhi anika amandla ukudalwa kwamanethiwekhi amakhulu, ayinkimbinkimbi, avumela izinhlangano ukuthi zilinganise ingqalasizinda yazo yedijithali ngaphandle kokuphazamisa ukusebenza.
Ukusekelwa kobuchwepheshe besimanje: Amaswishi enethiwekhi athuthukile ukuze ahambisane nentuthuko yezobuchwepheshe, asekela amanani okudlulisa idatha asheshayo, Amandla phezu kwe-Ethernet (PoE), namandla okuphatha inethiwekhi athuthukile.
Ukuvela kokushintsha kwenethiwekhi
Ukushintsha kwenethiwekhi kube nokuguquguquka okukhulu kusukela kwasungulwa. Kusuka kumaswishi ayisisekelo Esendlalelo 2 aphatha ukudlulisela idatha okulula kuya kumaswishi e-Layer 3 athuthukisiwe ahlanganisa amandla omzila, ubuchwepheshe buyaqhubeka buthuthukela ukuze buhlangabezane nezidingo ezikhulayo zamanethiwekhi esimanjemanje.
Namuhla, ukushintshwa kwenethiwekhi kuyingxenye yokusebenza kwezikhungo zedatha, amanethiwekhi wamabhizinisi, nezimo zezimboni. Basekela uhla olubanzi lwezinhlelo zokusebenza, kusukela ekuxhumeni amadivaysi e-IoT kanye nokunika amandla izakhiwo ezihlakaniphile, ukuvumela ukufinyelela ku-inthanethi ngesivinini esikhulu kanye nokwenza lula ukusebenzisa ikhompuyutha yamafu.
Ukubheka ikusasa
Njengoba siqhubekela phambili enkathini yenguquko yedijithali, indima yokushintshwa kwenethiwekhi izoqhubeka nokuvela. Ngokufika kwe-5G, i-edge computing kanye ne-Inthanethi Yezinto (IoT), isidingo sezixazululo zenethiwekhi ezinamandla neziguquguqukayo sizokhula kuphela. Amaswishi enethiwekhi anekhono lokuzivumelanisa nalezi zinselele ezintsha futhi azoqhubeka nokuba phambili kulokhu kuthuthukiswa, aqinisekise ukuthi idatha ingageleza ngaphandle komthungo, ngokuphepha nangokuphumelelayo emhlabeni wethu oxhumeka ngokuya ngokuya.
Ekuphetheni
Ukuzalwa kokushintshwa kwenethiwekhi kuwumlando wokuxhumana kwedijithali. Kuguqule indlela idatha ephathwa ngayo futhi edluliswa ngayo ngamanethiwekhi, kwabeka isisekelo samanethiwekhi athuthukile, angakala futhi avikelekile esithembele kuwo namuhla. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, amaswishi enethiwekhi ngokungangabazeki azodlala indima ebalulekile ekulolongeni ikusasa lokuxhumana komhlaba wonke.
