Yintoni i-switch yenethiwekhi kwaye isebenza njani?

Kwiminyaka yedijithali, iziseko zophuhliso zenethiwekhi zidlala indima ebalulekileyo njengamashishini kunye namakhaya axhomekeke kwizixhobo ezininzi ezinxulumene ne-Intanethi. Elinye lawona macandelo aphambili ezi zibonelelo yinethiwekhi yokutshintsha, isixhobo esiqinisekisa ukuntywila okuthambileyo kwedatha phakathi kwezixhobo kwinethiwekhi yengingqi. Kodwa yintoni kanye kanye inethiwekhi yokutshintsha? Ingaba isebenza kanjani?

Yintoni i-switch yenethiwekhi?
Inguqulelo yenethiwekhi sisixhobo esibonisa izixhobo ezinxibelelana ngezixhobo ezininzi kwinethiwekhi yendawo yengingqi (LAN). Ezi zixhobo zinokubandakanya iikhompyuter, abashicileli, iiseva, iifowuni ze-IP, kunye neekhamera zezokhuseleko. Ngokungafaniyo nenethiwekhi elula yosasazo kwidatha kwisixhobo ngasinye, i-switch ikhuthazekile: Ikhokela idatha kwizixhobo ezithile eziyifunayo, ukuqhubela phambili ukugcwala kwenethiwekhi.

Kwishishini kunye neenethiwekhi zasekhaya, ukutshintshela kusebenza njengamanqaku aphambili okunxibelelana, ukuvumela izixhobo zokunxibelelana nenye ngokufanelekileyo. Oku kubaluleke kakhulu kwiimeko ezinesidingo sedatha ephezulu, njengoko i-switch inokujongana nemithamo enkulu yezithuthi ngaphandle kokukhulula inethiwekhi.

Isebenza njani inethiwekhi yomsebenzi?
Umsebenzi ophambili wokutshintsha kwenethiwekhi kukufumana, qhubeke, kwaye uqhubekise idatha kwifowuni efanelekileyo. Nali inyathelo elinamanyathelo ngamanyathelo ngendlela yokutshintsha le nkqubo:

Ukufumana iipakethi: Xa isixhobo kwinethiwekhi, njengekhompyuter, ithumela idatha, idatha iqhekezwe kwiiyunithi ezincinci ezibizwa ngokuba ziipakethi. Ezi pakethi zithunyelwa kwiswitshi.

Funda idilesi yeMac: Zonke ifowuni kwinethiwekhi inesazisi esahlukileyo esibizwa ngokuba yi-Mac (Ulawulo loFundo lweMidiya). Ukutshintsha kuphonononga iidilesi zazo zonke izixhobo ezixhwanweyo kwaye zibabambisa etafileni, ziyivumela ukuba ichonge indawo nganye kwinethiwekhi.

Idatha ngqo kwindawo efanelekileyo: usebenzisa itheyibhile yedilesi ye-MAC, iswitshi ingamisela indawo eya kuyo iPacket nganye. Endaweni yedatha yosasazo kuzo zonke izixhobo, ithumela iipakethi kwisixhobo ekujoliswe kuyo, esigcina i-bandwidth kwaye inyuse isantya senethiwekhi.

Ukulawulwa kwezithuthi ngokufanelekileyo: Ngokukhuthala ukugcwala ngokungxamisekileyo, i-switch iqinisekisa ukuba isixhobo ngasinye sifumana idatha ngaphandle kokulibazisa.

Kutheni i-switches yenethiwekhi ibalulekile?
Kuyo nayiphi na intlangano okanye iseti apho izixhobo ezininzi kufuneka zinxibelelane, ukutshintshela kubalulekile kulawulo lwedatha efanelekileyo. Nazi ezinye zezizathu eziphambili zokuba kutheni i-switches yenethiwekhi ibalulekile:

Ukuphuculwa kokuSebenza kwenethiwekhi

Ukhuseleko oluphuculweyo: Ukutshintshwa okulungiselelwe ukubonelela ngeempawu ezinceda ukulawula ukufikelela kwenethiwekhi, ukufumana izoyikiso, kunye nezithuthi zecandelo ukongeza ulwazi lokhuseleko.

I-Scialser: Njengoko ishishini lakho likhula, ukutshintshisela kunokongeza ngokulula izixhobo ezingaphezulu kwinethiwekhi ngaphandle kwesantya okanye ukusebenza.

Ukuthembeka: Ukutshintshwa kwenzelwe ukuphatha ukuhamba kwedatha eqhubekayo kwaye kuyaziqhelanisa nokuqinisekisa ukunxibelelana okungaphazanyiswa kuwo wonke uthungelwano.

Uhlobo lwenethiwekhi yokutshintsha
Zininzi iintlobo zokutshintsha kwenethiwekhi, yenzelwe i-thegement yeemfuno ezahlukeneyo:

Iitshizi ezingalunganga: Ezi zixhobo ezilula zeplagi kwaye zihlala zisetyenziswa ekhaya okanye kwinethiwekhi encinci yeshishini. Bafuna ukungabinakho nokulawula ngokuzenzekelayo izithuthi phakathi kwezixhobo ezixhunyiweyo.

Ukutshintshwa okulawulwa: ezi zinto zitshintshiwe zibonelela ngolawulo olungaphezulu kunye nokwenza izinto zokwenza ngokweziko, zenza ukuba zilungele iitopaji enkulu okanye ezingaphezulu. Abalawuli banokucwangcisa useto ukuze babeka phambili iintlobo ezithile zendlela, ukufikelela kulawulo, nokubeka iliso kwimpilo yenethiwekhi.

I-Poe (iMandla ngaphezulu kwe-Ethernet) Switchs: Ezi zitshintshi zinokudlulisela amagunya ngaphezulu kweentambo, zisenza ukuba zilungele iikhamera ze-IP kunye neendawo zokungena ezingenazingcingo apho iindawo zokungena kwamandla zinokulinganiselwa.

ukuququmbela
Ukutshintsha kwenethiwekhi kungaphezulu nje kwesinxibelelanisi kwisixhobo sakho; Licandelo elibalulekileyo eligcina inethiwekhi yakho isebenza kakuhle, ngokukhuselekileyo, kwaye ngokufanelekileyo. Ngokukhokela idatha kuphela kubamkeli bayo, ukutshintshela kuyanceda ukugcina isantya, ukunciphisa ukuxinana, nokubonelela ngendawo ethembekileyo yokuhlala yendawo yedijithali. Nokuba inethiwekhi exakekileyo yeshishini okanye ikhaya elinobuchule, ukutshintsha kwenethiwekhi entliziyweni yokunxibelelana ngaphandle kokungena engenamthungo exhasa iimfuno zehlabathi elixhunyiwe namhlanje.

Njengoko itekhnoloji yokunxibelelana nenethiwekhi iyaqhubeka ukuqhubela phambili, ukutshintshela kuya kuba namandla kwaye bubonisa isityebi, ukubonelela amashishini kunye namakhaya anokufakwa okungakumbi, ukhuseleko, kunye nokhetho lolawulo. Njengoko uthungelwano luyaqhubeka lukhula kwaye luvela, ukubaluleka kolawulo lwedatha olusebenzayo ngokuguqula kuya kukhula kuphela.
