Njengemveliso yonxibelelwano lwedatha ebalulekileyo,iiswitshi Ethernet yamashishinikufuneka ivuleke kwaye ihambelane neemveliso ezivela kubavelisi abaninzi ukuze kuqinisekiswe ukusebenza okuzinzile kwexesha elide kunye nokukhuselekileyo kwenkqubo.Ukuba uthembele kuphela kumenzi othile, umngcipheko uphezulu kakhulu.Ngoko ke, ngokusekelwe kwingqwalasela kunye nokuhambelana, ingqwalasela epheleleyo kufuneka inikwe ukuxubaiiswitshi Ethernet yamashishiniukusuka kubenzi abahlukeneyo ukwenza inethiwekhi yeringi engafunekiyo ukubeka isiseko esiluqilima sokwandiswa kwenethiwekhi yexesha elizayo.Ke, ngaba iiswitshi ze-Ethernet zemizi-mveliso ezivela kubavelisi abahlukeneyo zakhainethiwekhi yeringi engafunekiyo?

Impendulo nguewe.I-Industrial Ethernet switchs evela kubakhiqizi abahlukeneyo banokunxibelelana omnye nomnye nge-loop yombane port kunye ne-optical port.

⑴ Iprothokholi yothungelwano

Imigangatho yesizwe efanelekileyo, imigangatho yeshishini laseGuodian, kunye nemigangatho yoshishino equlunqwayo yonke ichaza ngokucacileyo ukuba "uthungelwano lunokwakheka ngokweemfuno zenkqubo yamandla, kwaye iprothokholi yothungelwano kufuneka yamkele iprothokholi esemgangathweni yamazwe ngamazwe:RSTP, MSTP, njl.”Ke ngoko, ukongeza ekuxhaseni iprothokholi yeRingi yabucala enamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda aphuhliswe ngumenzi ngamnye, iswitshi ye-Ethernet yeshishini kufuneka kwakhona ixhase i-RSTP kunye ne-MSTP yeenkqubo zenethiwekhi zeringi ezisemgangathweni zamazwe ngamazwe.Logama nje i-RSTP kunye ne-MSTP iiprothokholi zothungelwano zeringi ezisemgangathweni zamazwe ngamazwe zamkelwe, iiswitshi ze-Ethernet zemizi-mveliso ezivela kubavelisi abahlukeneyo zinokwenza uthungelwano kunye nezakhiwo ze-topological ezifana neenkwenkwezi, i-ring, kunye nomthi.

⑵ umaleko womzimba

Akukho ngxaki kwi-interconnection kunye ne-intercommunication yokutshintsha ukusuka kubakhiqizi abahlukeneyo kwinqanaba lomzimba, nje ukuba iiparitha zeendaba zihambelana, njengokuba i-industrial-grade optical fiber transceiver i-mode-mode okanye i-multi-mode, kunye ne-wavelength. iiparamitha ze-optical fiber transceiver.Ukushwankathela, kungakhathaliseki ukuba yeyiphi iprotocol yothungelwano okanye umaleko womzimba, iiswitshi ezivela kubavelisi abahlukeneyo zinokunxibelelana omnye nomnye xa zenza inethiwekhi yeringi efanayo.
