Ubuchwepheshe be-Ungqimba 3I-switch ikhula ngokuya ngokuvuthwa futhi izinhlelo zayo ziya ngokuya ziba zibanzi.Ebangeni elithile, inezinzuzo eziningi kunama-routers, kodwa kusenomehluko omkhulu phakathi kokushintshwa kwezingqimba ezintathu kanye nomzila.Kunethiwekhi yendawo yendawo, ukushintshwa kwezendlalelo ezintathu kunezinzuzo ezisobala.

1. Umkhawulokudonsa wokudlulisa phakathi kwama-subnet ungabiwa ngokungekho emthethweni:

Kurutha yendabuko, imbobo ye-serial ngayinye ingaxhunywa ku-subnet, futhi izinga lale subnet elidluliswa ngomzila linqunyelwe ngokuqondile umkhawulokudonsa wesixhumi esibonakalayo.Umehluko ukuthi iswishi yesendlalelo sesithathu ichaza izimbobo eziningi njengenethiwekhi ebonakalayo (i-VLAN), isebenzisa inethiwekhi ebonakalayo ehlanganiswe nezimbobo eziningi njengesixhumi esibonakalayo senethiwekhi, futhi ithumela ulwazi olukuyo kusendlalelo sesithathu ngokusebenzisa izimbobo ezakha i-virtual. inethiwekhi.Ukushintsha, ngenxa yokuthi inani lamachweba lingacaciswa ngokungafanele, umkhawulokudonsa wokudlulisa phakathi kwama-subnet awukhawulelwe.

2. Ukwabiwa okunengqondo kwezinsiza zolwazi

Ngenxa yokuthi isistimu yenethiwekhi exhunywe ukushintshwa kwesigaba sesithathu isetshenziswa, izinga lensiza le-subnet yokufinyelela alihlukile kunenani lensiza yenethiwekhi yomhlaba wonke, ngakho-ke akunangqondo ukusetha iseva ehlukile.Ngokusungula ngokuqondile iqoqo leseva kunethiwekhi yomhlaba wonke, ngaphansi kwesisekelo sokuqinisekisa izinga lokudluliselwa kwe-intranethi ye-broadband, ayikwazi nje ukulondoloza izindleko, kodwa futhi isebenzise ngokugcwele izinzuzo zesofthiwe kanye nezinsiza ze-hardware zeseva yeqoqo, futhi ingalungisa ngokunengqondo futhi iphathe izinsiza zolwazi ezahlukahlukene.Le nkinga kunzima ukuyixazulula kunethiwekhi yomzila.

3. Yehlisa izindleko

Ekwakhiweni kwenethiwekhi yebhizinisi, ngoba abantu ngokuvamile basebenzisa izendlalelo ezimbili zokushintshwa ukuze benze isizinda esifanayo sokusakaza esingaphansi, ama-routers asetshenziselwa ukuxhuma i-subnet ngayinye, okwenza inethiwekhi yebhizinisi ibe i-intranet, futhi ama-routers ayabiza, ngakho amabhizinisi asekela ama-intranethi Inethiwekhi ayikwazi. ukunciphisa izindleko zemishini.Manje, ohlelweni lwenethiwekhi esemgqeni, abantu basebenzisa ukushintshwa kwesendlalelo sesithathu kumklamo wenethiwekhi, hhayi nje kuphela ukuthi i-subnet ye-virtual ingahlukaniswa ngokungafanele ibe ama-subnets, kodwa futhi ingaqedela ukuxhumana phakathi kwama-subnets ngokusebenzisa umsebenzi womzila onezendlalelo ezintathu weswishi , Okusho ukuthi, ukusungulwa kwama-subnets nama-subnets angaphakathi kungaqedwa ngokushintsha, okusindisa kakhulu ama-routers abizayo.
